The condition resulting from the absence or deficiency of LACTASE in the MUCOSA cells of the GASTROINTESTINAL TRACT, and the inability to break down LACTOSE in milk for ABSORPTION. Bacterial fermentation of the unabsorbed lactose leads to symptoms that range from a mild indigestion (DYSPEPSIA) to severe DIARRHEA. Lactose intolerance may be an inborn error or acquired.
A measure of a patient's ability to break down lactose.
An enzyme which catalyzes the hydrolysis of LACTOSE to D-GALACTOSE and D-GLUCOSE. Defects in the enzyme cause LACTOSE INTOLERANCE.
Production or presence of gas in the gastrointestinal tract which may be expelled through the anus.
A disaccharide of GLUCOSE and GALACTOSE in human and cow milk. It is used in pharmacy for tablets, in medicine as a nutrient, and in industry.
Raw and processed or manufactured milk and milk-derived products. These are usually from cows (bovine) but are also from goats, sheep, reindeer, and water buffalo.
Any tests done on exhaled air.
The multifunctional protein that contains two enzyme domains. The first domain (EC 3.2.1.62) hydrolyzes glycosyl-N-acylsphingosine to a sugar and N-acylsphingosine. The second domain (EC 3.2.1.108) hydrolyzes LACTOSE and is found in the intestinal brush border membrane. Loss of activity for this enzyme in humans results in LACTOSE INTOLERANCE.
The first chemical element in the periodic table. It has the atomic symbol H, atomic number 1, and atomic weight [1.00784; 1.00811]. It exists, under normal conditions, as a colorless, odorless, tasteless, diatomic gas. Hydrogen ions are PROTONS. Besides the common H1 isotope, hydrogen exists as the stable isotope DEUTERIUM and the unstable, radioactive isotope TRITIUM.
The white liquid secreted by the mammary glands. It contains proteins, sugar, lipids, vitamins, and minerals.
A syndrome produced by severe protein deficiency, characterized by retarded growth, changes in skin and hair pigment, edema, and pathologic changes in the liver, including fatty infiltration, necrosis, and fibrosis. The word is a local name in Gold Coast, Africa, meaning "displaced child". Although first reported from Africa, kwashiorkor is now known throughout the world, but mainly in the tropics and subtropics. It is considered to be related to marasmus. (From Dorland, 27th ed)
Sensation of discomfort, distress, or agony in the abdominal region.
General term for a group of MALNUTRITION syndromes caused by failure of normal INTESTINAL ABSORPTION of nutrients.
Calcium compounds used as food supplements or in food to supply the body with calcium. Dietary calcium is needed during growth for bone development and for maintenance of skeletal integrity later in life to prevent osteoporosis.
A component of the NATIONAL INSTITUTES OF HEALTH concerned with research, overall planning, promoting, and administering mental health programs and research. It was established in 1949.
A pathological state in which BLOOD GLUCOSE level is less than approximately 140 mg/100 ml of PLASMA at fasting, and above approximately 200 mg/100 ml plasma at 30-, 60-, or 90-minute during a GLUCOSE TOLERANCE TEST. This condition is seen frequently in DIABETES MELLITUS, but also occurs with other diseases and MALNUTRITION.
An increased liquidity or decreased consistency of FECES, such as running stool. Fecal consistency is related to the ratio of water-holding capacity of insoluble solids to total water, rather than the amount of water present. Diarrhea is not hyperdefecation or increased fecal weight.
A disorder with chronic or recurrent colonic symptoms without a clearcut etiology. This condition is characterized by chronic or recurrent ABDOMINAL PAIN, bloating, MUCUS in FECES, and an erratic disturbance of DEFECATION.
The portion of the GASTROINTESTINAL TRACT between the PYLORUS of the STOMACH and the ILEOCECAL VALVE of the LARGE INTESTINE. It is divisible into three portions: the DUODENUM, the JEJUNUM, and the ILEUM.
An autosomal recessive fructose metabolism disorder due to deficient fructose-1-phosphate aldolase (EC 2.1.2.13) activity, resulting in accumulation of fructose-1-phosphate. The accumulated fructose-1-phosphate inhibits glycogenolysis and gluconeogenesis, causing severe hypoglycemia following ingestion of fructose. Prolonged fructose ingestion in infants leads ultimately to hepatic failure and death. Patients develop a strong distaste for sweet food, and avoid a chronic course of the disease by remaining on a fructose- and sucrose-free diet.
A group of enzymes that catalyzes the hydrolysis of terminal, non-reducing beta-D-galactose residues in beta-galactosides. Deficiency of beta-Galactosidase A1 may cause GANGLIOSIDOSIS, GM1.
Symptoms of cerebral hypoperfusion or autonomic overaction which develop while the subject is standing, but are relieved on recumbency. Types of this include NEUROCARDIOGENIC SYNCOPE; POSTURAL ORTHOSTATIC TACHYCARDIA SYNDROME; and neurogenic ORTHOSTATIC HYPOTENSION. (From Noseworthy, JH., Neurological Therapeutics Principles and Practice, 2007, p2575-2576)
An enzyme complex that catalyzes the transfer of GALACTOSE from UDP GALACTOSE to GLUCOSE, forming LACTOSE. The enzyme complex is composed of a B subunit, ALPHA-LACTALBUMIN, which changes the substrate specificity of the A subunit, N-ACETYLLACTOSAMINE SYNTHASE, from N-ACETYLGLUCOSAMINE to glucose making lactose synthesis the preferred reaction.

Racial bias in federal nutrition policy, Part I: The public health implications of variations in lactase persistence. (1/280)

The Dietary Guidelines for Americans from the basis for all federal nutrition programs and incorporate the Food Guide Pyramid, a tool to educate consumers on putting the Guidelines into practice. The Pyramid recommends two to three daily servings of dairy products. However, research has shown that lactase nonpersistence, the loss of enzymes that digest the milk sugar lactose, occurs in a majority of African-, Asian-, Hispanic-, and Native-American individuals. Whites are less likely to develop lactase nonpersistence and less likely to have symptoms when it does occur. Calcium is available in other foods that do not contain lactose. Osteoporosis is less common among African Americans and Mexican Americans than among whites, and there is little evidence that dairy products have an effect on osteoporosis among racial minorities. Evidence suggests that a modification of federal nutrition policies, making dairy-product use optional in light of other calcium sources, may be a helpful public health measure.  (+info)

Fructooligosaccharides and lactulose cause more symptoms in lactose maldigesters and subjects with pseudohypolactasia than in control lactose digesters. (2/280)

BACKGROUND: Many lactose maldigesters tolerate more lactose in experimental studies than in everyday life, in which their symptoms may result from other carbohydrates as well. OBJECTIVE: The question of whether the symptoms caused by large quantities of carbohydrates are more severe in lactose maldigesters than in control lactose digesters or in lactose digesters who report milk to be the cause of their gastrointestinal symptoms (pseudohypolactasic subjects) was studied in a randomized, double-blind, crossover study. Comparisons between commonly used diagnostic methods for lactose maldigestion were also made. DESIGN: The subjects were 40 women aged 20-63 y from 3 groups: lactose maldigesters (n = 12), pseudohypolactasic subjects (n = 15), and control lactose digesters (n = 13). The subjects were given either 50 g lactose, 50 g sucrose, 25 g lactulose, or 25 g fructooligosaccharides. After carbohydrate ingestion, urine was collected and the breath-hydrogen concentration was measured every 30 min for 3 h. Blood glucose was measured every 20 min for 1 h and subjective gastrointestinal symptoms were monitored for 8 h with a questionnaire. RESULTS: When lactulose and fructooligosaccharides were ingested, the lactose maldigesters (P = 0.04 and 0.09, respectively) and the pseudohypolactasic subjects (P = 0.006 and 0.01, respectively) reported more symptoms than did the control lactose digesters. Sucrose caused more symptoms in the lactose maldigesters than in the control lactose digesters (P = 0.05). CONCLUSIONS: Lactose maldigesters and lactose digesters with pseudohypolactasia experience more symptoms than control lactose digesters after a single intake of large amounts of indigestible carbohydrates. Lactose maldigesters also experience more symptoms after ingesting sucrose.  (+info)

Lactose malabsorption and rate of bone loss in older women. (3/280)

OBJECTIVES: to study the prevalence of lactose malabsorption with increasing age and to determine whether lactose malabsorbers consume less dietary calcium, have lower bone mineral density or display faster bone loss than lactose absorbers. DESIGN: 80 healthy Caucasian women aged 40-79 years (20 per decade) were studied for 1 year. METHODS: breath hydrogen exhalation was measured for 3 after a 50 g oral lactose challenge. Bone density was assessed in the radius, femoral neck, lumbar spine and total body by dual energy x-ray absorptiometry and dietary calcium intake was estimated by 4-day diet records and food-frequency questionnaires. RESULTS: lactose malabsorption rose with age (15% in those aged 40-59 years versus 50% in those aged 60-79; P < 0.01). Malabsorbers aged 70-79 years consumed significantly less calcium than lactose absorbers of this age (P < 0.05). Baseline total body calcium values were lower in lactose malabsorbers (n=26) than in lactose absorbers (n=54) but age-adjustment eliminated this difference. Bone change (% per year) was correlated with dietary calcium intake at the femoral neck and trochanter (P < 0.05) but was not statistically greater in malabsorbers than in absorbers. CONCLUSIONS: the ability to absorb lactose declines in the 7th decade. This may contribute to decreased dietary intakes of milk products and calcium in elderly women. However, lactose malabsorption without reduction in calcium intake has little effect on bone mineral density or the rate of bone loss.  (+info)

Lactose absorption in patients with ovarian cancer. (4/280)

To determine whether lactase persistence might be related to ovarian cancer risk, in 1994-1995 the authors assessed the capacity to digest lactose by measuring breath hydrogen production after oral administration of lactose in 50 women with ovarian cancer and 100 healthy controls. All of the women came from Sassari (Sardinia), Italy, an area where the population has a high frequency of lactose malabsorption. Thirty percent of cases were lactose absorbers, as compared with 15% of controls. The odds ratio for ovarian cancer among lactose absorbers was 2.51 (95% confidence interval 1.10-5.68). These results provide some support for a role of lactose ingestion and galactose cytotoxicity in the pathogenesis of ovarian cancer.  (+info)

Galactose consumption induces conditioned flavor avoidance in rats. (5/280)

Recent findings revealed that intragastric infusions of galactose conditioned a flavor avoidance in adult rats. To determine whether the galactose-conditioned avoidance was due to the infusion procedure, we investigated the flavor conditioning effect of orally consumed galactose. Food-restricted rats drank a flavored galactose solution, a flavored fructose solution and a flavored saccharin solution in separate one-bottle training sessions; grape, cherry and orange flavors were used. Because fructose is sweeter than galactose, saccharin was added to the galactose solution to increase its palatability. Pre- and posttraining preferences for the galactose and fructose solutions were evaluated in two-bottle choice tests. Also, preferences for the sugar-paired flavors were evaluated in two-bottle tests with the flavors presented in saccharin. In Experiment 1, rats were trained with flavored 80 g/L fructose, 80 g/L galactose + 2 g/L saccharin, and 2 g/L saccharin solutions (20 mL/d). Their preference for the flavored galactose solution changed (P < 0.01) from 76% (pretraining) to 19% (posttraining). The rats also avoided (P < 0.05) the flavor paired with the galactose solution in choice tests with the fructose-paired flavor and the saccharin-paired flavor. Similar pre- to posttraining preference reversals were obtained in Experiments 2 and 3, which used 20 g/L galactose and fructose solutions, and 20 g/L galactose and fructose solutions mixed with 20 g/L glucose, respectively. These findings, together with the intragastric infusion data, demonstrate that galactose has aversive postingestive consequences in adult rats even at low concentrations (20 g/L). Unlike lactose intolerance, which is due to intestinal malabsorption, this galactose-induced flavor avoidance is presumably due to the slow and incomplete postabsorptive metabolism of galactose.  (+info)

Ibuprofen augments gastrointestinal symptoms in lactose maldigesters during a lactose tolerance test. (6/280)

BACKGROUND: Clinical symptoms during lactose tolerance test mimic those seen after therapeutic administration of prostaglandins, and resemble inflammatory processes. AIM: To investigate the possibility that lactose-induced gastrointestinal symptoms are associated with prostaglandins and/or nitric oxide. METHODS: After an overnight fast, nine maldigesters ingested lactose or sucrose with or without an inhibitor of prostaglandin synthesis (ibuprofen), in a randomised double-blind crossover trial. Gastrointestinal symptoms, concentrations of PGE2-M in blood and urine, and urinary 6-keto PGF1alpha (as indicators of prostaglandin synthesis), and urinary nitrate and nitrite as well as cyclic GMP excretions (as indicators of nitric oxide formation), were measured. RESULTS: Ibuprofen increased the first 3-h symptom scores (flatulence + borborygmi + abdominal bloating + pain) caused by lactose (P=0.008) but not sucrose. The concentrations of PGE2-M in the plasma and in the urine were unaffected. Lactose increased the urinary excretion of 6-keto PGF1alpha by about 30% (P=0.17), which was inhibited by ibuprofen (P=0.02). The production of nitric oxide was unaffected by lactose or ibuprofen. CONCLUSION: The inhibition of prostaglandin synthesis intensified gastrointestinal symptoms in lactose maldigesters, suggesting a negligible role for prostanoids in lactose-induced symptoms.  (+info)

Survival and therapeutic potential of probiotic organisms with reference to Lactobacillus acidophilus and Bifidobacterium spp. (7/280)

The present paper provides an overview on the use of probiotic organisms as live supplements, with particular emphasis on Lactobacillus acidophilus and Bifidobacterium spp. The therapeutic potential of these bacteria in fermented dairy products is dependent on their survival during manufacture and storage. Probiotic bacteria are increasingly used in food and pharmaceutical applications to balance disturbed intestinal microflora and related dysfunction of the human gastrointestinal tract. Lactobacillus acidophilus and Bifidobacterium spp. have been reported to be beneficial probiotic organisms that provide excellent therapeutic benefits. The biological activity of probiotic bacteria is due in part to their ability to attach to enterocytes. This inhibits the binding of enteric pathogens by a process of competitive exclusion. Attachment of probiotic bacteria to cell surface receptors of enterocytes also initiates signalling events that result in the synthesis of cytokines. Probiotic bacteria also exert an influence on commensal micro-organisms by the production of lactic acid and bacteriocins. These substances inhibit growth of pathogens and also alter the ecological balance of enteric commensals. Production of butyric acid by some probiotic bacteria affects the turnover of enterocytes and neutralizes the activity of dietary carcinogens, such as nitrosamines, that are generated by the metabolic activity of commensal bacteria in subjects consuming a high-protein diet. Therefore, inclusion of probiotic bacteria in fermented dairy products enhances their value as better therapeutic functional foods. However, insufficient viability and survival of these bacteria remain a problem in commercial food products. By selecting better functional probiotic strains and adopting improved methods to enhance survival, including the use of appropriate prebiotics and the optimal combination of probiotics and prebiotics (synbiotics), an increased delivery of viable bacteria in fermented products to the consumers can be achieved.  (+info)

Effect of an episode of severe malnutrition and age on lactose absorption by recovered infants and children. (8/280)

The degree of which the ability to absorb lactose can be regained after recovery from an acute episode of severe malnutrition is in doubt. Lactase activity was indirectly assessed by means of a standard lactose tolerance test (2 g lactose per kilogram of body weight) in 71 Peruvian Mestizo infants and children (age 5 to 55 months) who had suffered such an episode. All were studied just before discharge after several months of hospital rehabilitation, during which linear growth and weight gain had accelerated and signs of significant malabsorption of other nutrients had disappeared. Only 39% of the total group had a positive test (delta blood glucose greater than 25 mg/dl); there was a decreasing proportion of positive responders with increasing age. No difference in response attributable to type or severity of malnutrition was found. Comparison of the present data with previous data from children in the same community who had never been acutely malnourished suggests that acute malnutrition may hasten the permanent decline of lactase activity normally expected later in life.  (+info)

Lactose intolerance is a digestive condition in which the body has difficulty digesting lactose, a sugar found in milk and dairy products. This occurs due to a deficiency or insufficiency of lactase, an enzyme produced by the small intestine that breaks down lactose into simpler sugars (glucose and galactose) for absorption. When there is not enough lactase to digest the consumed lactose, it passes undigested into the large intestine, where it is fermented by bacteria, leading to various gastrointestinal symptoms.

The symptoms of lactose intolerance may include bloating, cramps, diarrhea, nausea, and gas, usually occurring within 30 minutes to two hours after consuming dairy products. The severity of these symptoms can vary depending on the amount of lactose consumed and an individual's level of lactase deficiency or insufficiency.

Lactose intolerance is not life-threatening but can cause discomfort and may affect a person's quality of life. It is essential to manage the condition through dietary modifications, such as consuming smaller amounts of dairy products, choosing lactose-free or reduced-lactose options, or using lactase enzyme supplements before eating dairy products. In some cases, a healthcare professional may recommend additional management strategies based on an individual's specific needs and medical history.

The lactose tolerance test is a medical procedure used to determine the body's ability to digest lactose, a sugar found in milk and other dairy products. In this test, a patient is given a liquid that contains a high amount of lactose to drink. Blood samples are then taken over a two-hour period following the consumption of the lactose solution. These blood samples are tested for glucose levels.

If the body is able to digest lactose properly, the lactose will be broken down into glucose and absorbed into the bloodstream, resulting in an increase in blood glucose levels. However, if the body has difficulty digesting lactose (lactose intolerance), little or no increase in blood glucose levels will be observed.

A positive lactose tolerance test indicates that the individual can tolerate lactose and has a functioning lactase enzyme in their small intestine. A negative result suggests lactose intolerance, which is often due to insufficient lactase production. This condition can lead to symptoms such as bloating, diarrhea, and abdominal cramps after consuming dairy products.

Lactase is a specific enzyme that is produced by the cells lining the small intestine in humans and other mammals. Its primary function is to break down lactose, a sugar found in milk and dairy products, into simpler sugars called glucose and galactose, which can then be absorbed into the bloodstream.

Lactase is most active during infancy and early childhood, when breast milk or formula is the primary source of nutrition. However, in some individuals, lactase production decreases after weaning, leading to a condition called lactose intolerance. Lactose intolerant individuals have difficulty digesting lactose, which can result in various gastrointestinal symptoms such as bloating, cramps, diarrhea, and gas.

Supplemental lactase enzymes are available over the counter to help lactose-intolerant individuals digest dairy products more comfortably.

Flatulence is the medical term for the release of intestinal gas from the rectum, commonly known as passing gas or farting. It is a normal bodily function that occurs when the body digests food in the stomach and intestines.

During digestion, the body breaks down food into nutrients that can be absorbed into the bloodstream. However, not all food particles can be fully broken down, and some of them reach the large intestine, where they are fermented by bacteria. This fermentation process produces gases such as nitrogen, oxygen, carbon dioxide, hydrogen, and methane.

The buildup of these gases in the digestive tract can cause discomfort, bloating, and the urge to pass gas. The average person passes gas about 10-20 times a day, although this can vary widely from person to person.

While flatulence is a normal bodily function, excessive or frequent passing of gas can be a sign of an underlying digestive issue such as irritable bowel syndrome (IBS), lactose intolerance, or gastrointestinal infections. If you are experiencing persistent or severe symptoms, it is recommended to consult with a healthcare professional for further evaluation and treatment.

Lactose is a disaccharide, a type of sugar, that is naturally found in milk and dairy products. It is made up of two simple sugars, glucose and galactose, linked together. In order for the body to absorb and use lactose, it must be broken down into these simpler sugars by an enzyme called lactase, which is produced in the lining of the small intestine.

People who have a deficiency of lactase are unable to fully digest lactose, leading to symptoms such as bloating, diarrhea, and abdominal cramps, a condition known as lactose intolerance.

Dairy products are foods produced from the milk of animals, primarily cows but also goats, sheep, and buffalo. The term "dairy" refers to the place or process where these products are made. According to the medical definition, dairy products include a variety of foods such as:

1. Milk - This is the liquid produced by mammals to feed their young. It's rich in nutrients like calcium, protein, and vitamins A, D, and B12.
2. Cheese - Made from milk, it can vary greatly in texture, taste, and nutritional content depending on the type. Cheese is a good source of protein and calcium.
3. Yogurt - This is formed by bacterial fermentation of milk. It contains probiotics which are beneficial bacteria that can help maintain gut health.
4. Butter - Made from cream or churned milk, butter is high in fat and calories but also provides some essential nutrients like vitamin A.
5. Ice Cream - A frozen dessert made from cream, milk, sugar, and often egg yolks. While it can be a source of calcium and protein, it's also high in sugar and should be consumed in moderation.
6. Casein and Whey Proteins - These are proteins derived from milk that are often used as dietary supplements for muscle building and recovery after exercise.

Individuals who are lactose intolerant may have difficulty digesting dairy products due to the sugar lactose found in them. For such individuals, there are lactose-free versions of these products available or they can opt for plant-based alternatives like almond milk, soy milk, etc.

A breath test is a medical or forensic procedure used to analyze a sample of exhaled breath in order to detect and measure the presence of various substances, most commonly alcohol. The test is typically conducted using a device called a breathalyzer, which measures the amount of alcohol in the breath and converts it into a reading of blood alcohol concentration (BAC).

In addition to alcohol, breath tests can also be used to detect other substances such as drugs or volatile organic compounds (VOCs) that may indicate certain medical conditions. However, these types of breath tests are less common and may not be as reliable or accurate as other diagnostic tests.

Breath testing is commonly used by law enforcement officers to determine whether a driver is impaired by alcohol and to establish probable cause for arrest. It is also used in some healthcare settings to monitor patients who are being treated for alcohol abuse or dependence.

Lactase-phlorizin hydrolase (LPH) is an enzyme that is primarily responsible for the digestion of lactose, a sugar found in milk and dairy products. LPH is located on the brush border of the small intestine and catalyzes the hydrolysis of lactose into its component sugars, glucose and galactose, which are then absorbed into the bloodstream.

LPH is also known as lactase, and a deficiency in this enzyme can lead to a condition called lactose intolerance. In lactose intolerance, the body is unable to properly digest lactose, leading to symptoms such as bloating, diarrhea, and abdominal cramps.

Phlorizin is a compound that was originally used in research to study the properties of LPH. It is not typically associated with the physiological function of this enzyme in the body.

I'm sorry for any confusion, but "Hydrogen" is not a medical term. It is a chemical element with the symbol H and atomic number 1. It is the lightest and most abundant chemical element in the universe, making up about 75% of its elemental mass.

In a medical context, hydrogen can be discussed in terms of molecular hydrogen (H2) which has been studied for potential therapeutic benefits. Some research explores its use as an antioxidant and anti-inflammatory agent, but more studies are needed to confirm these effects and understand the mechanisms behind them.

Medically, "milk" is not defined. However, it is important to note that human babies are fed with breast milk, which is the secretion from the mammary glands of humans. It is rich in nutrients like proteins, fats, carbohydrates (lactose), vitamins and minerals that are essential for growth and development.

Other mammals also produce milk to feed their young. These include cows, goats, and sheep, among others. Their milk is often consumed by humans as a source of nutrition, especially in dairy products. However, the composition of these milks can vary significantly from human breast milk.

Kwashiorkor is a severe form of protein-energy malnutrition characterized by edema (fluid accumulation in the body's tissues), a distended belly, and a weakened immune system. It typically occurs in children between the ages of 1 and 3 who experience a sudden stop in breastfeeding and are switched to a diet that is low in protein but high in carbohydrates. The lack of protein impairs the body's ability to produce essential enzymes and hormones, leading to the characteristic symptoms of Kwashiorkor. It can also result in liver enlargement, skin lesions, hair changes, and impaired growth and development. Immediate medical attention is required for individuals with Kwashiorkor to prevent further complications and promote recovery.

Abdominal pain is defined as discomfort or painful sensation in the abdomen. The abdomen is the region of the body between the chest and the pelvis, and contains many important organs such as the stomach, small intestine, large intestine, liver, gallbladder, pancreas, and spleen. Abdominal pain can vary in intensity from mild to severe, and can be acute or chronic depending on the underlying cause.

Abdominal pain can have many different causes, ranging from benign conditions such as gastritis, indigestion, or constipation, to more serious conditions such as appendicitis, inflammatory bowel disease, or abdominal aortic aneurysm. The location, quality, and duration of the pain can provide important clues about its cause. For example, sharp, localized pain in the lower right quadrant of the abdomen may indicate appendicitis, while crampy, diffuse pain in the lower abdomen may suggest irritable bowel syndrome.

It is important to seek medical attention if you experience severe or persistent abdominal pain, especially if it is accompanied by other symptoms such as fever, vomiting, or bloody stools. A thorough physical examination, including a careful history and a focused abdominal exam, can help diagnose the underlying cause of the pain and guide appropriate treatment.

Malabsorption syndromes refer to a group of disorders in which the small intestine is unable to properly absorb nutrients from food, leading to various gastrointestinal and systemic symptoms. This can result from a variety of underlying conditions, including:

1. Mucosal damage: Conditions such as celiac disease, inflammatory bowel disease (IBD), or bacterial overgrowth that cause damage to the lining of the small intestine, impairing nutrient absorption.
2. Pancreatic insufficiency: A lack of digestive enzymes produced by the pancreas can lead to poor breakdown and absorption of fats, proteins, and carbohydrates. Examples include chronic pancreatitis or cystic fibrosis.
3. Bile acid deficiency: Insufficient bile acids, which are necessary for fat emulsification and absorption, can result in steatorrhea (fatty stools) and malabsorption. This may occur due to liver dysfunction, gallbladder removal, or ileal resection.
4. Motility disorders: Abnormalities in small intestine motility can affect nutrient absorption, as seen in conditions like gastroparesis, intestinal pseudo-obstruction, or scleroderma.
5. Structural abnormalities: Congenital or acquired structural defects of the small intestine, such as short bowel syndrome, may lead to malabsorption.
6. Infections: Certain bacterial, viral, or parasitic infections can cause transient malabsorption by damaging the intestinal mucosa or altering gut flora.

Symptoms of malabsorption syndromes may include diarrhea, steatorrhea, bloating, abdominal cramps, weight loss, and nutrient deficiencies. Diagnosis typically involves a combination of clinical evaluation, laboratory tests, radiologic imaging, and sometimes endoscopic procedures to identify the underlying cause. Treatment is focused on addressing the specific etiology and providing supportive care to manage symptoms and prevent complications.

Dietary calcium is a type of calcium that is obtained through food sources. Calcium is an essential mineral that is necessary for many bodily functions, including bone formation and maintenance, muscle contraction, nerve impulse transmission, and blood clotting.

The recommended daily intake of dietary calcium varies depending on age, sex, and other factors. For example, the recommended daily intake for adults aged 19-50 is 1000 mg, while women over 50 and men over 70 require 1200 mg per day.

Good dietary sources of calcium include dairy products such as milk, cheese, and yogurt; leafy green vegetables like broccoli and kale; fortified cereals and juices; and certain types of fish, such as salmon and sardines. It is important to note that some foods can inhibit the absorption of calcium, including oxalates found in spinach and rhubarb, and phytates found in whole grains and legumes.

If a person is unable to get enough calcium through their diet, they may need to take calcium supplements. However, it is important to talk to a healthcare provider before starting any new supplement regimen, as excessive intake of calcium can lead to negative health effects.

Glucose intolerance is a condition in which the body has difficulty processing and using glucose, or blood sugar, effectively. This results in higher than normal levels of glucose in the blood after eating, particularly after meals that are high in carbohydrates. Glucose intolerance can be an early sign of developing diabetes, specifically type 2 diabetes, and it may also indicate other metabolic disorders such as prediabetes or insulin resistance.

In a healthy individual, the pancreas produces insulin to help regulate blood sugar levels by facilitating glucose uptake in muscles, fat tissue, and the liver. When someone has glucose intolerance, their body may not produce enough insulin, or their cells may have become less responsive to insulin (insulin resistance), leading to impaired glucose metabolism.

Glucose intolerance can be diagnosed through various tests, including the oral glucose tolerance test (OGTT) and hemoglobin A1c (HbA1c) test. Treatment for glucose intolerance often involves lifestyle modifications such as weight loss, increased physical activity, and a balanced diet with reduced sugar and refined carbohydrate intake. In some cases, medication may be prescribed to help manage blood sugar levels more effectively.

Diarrhea is a condition in which an individual experiences loose, watery stools frequently, often exceeding three times a day. It can be acute, lasting for several days, or chronic, persisting for weeks or even months. Diarrhea can result from various factors, including viral, bacterial, or parasitic infections, food intolerances, medications, and underlying medical conditions such as inflammatory bowel disease or irritable bowel syndrome. Dehydration is a potential complication of diarrhea, particularly in severe cases or in vulnerable populations like young children and the elderly.

Irritable Bowel Syndrome (IBS) is a functional gastrointestinal disorder characterized by recurrent abdominal pain, bloating, and altered bowel habits in the absence of any structural or biochemical abnormalities. The symptoms can vary from person to person, ranging from mild to severe.

The exact cause of IBS is not known, but it's thought to involve a combination of factors such as muscle contractions in the intestine, abnormalities in the nervous system, inflammation in the intestines, severe infection, or changes in bacteria in the gut.

It's important to note that while IBS can cause great discomfort and distress, it does not lead to serious complications such as changes in bowel tissue or increased risk of colorectal cancer. However, it can significantly affect a person's quality of life and daily activities.

The small intestine is the portion of the gastrointestinal tract that extends from the pylorus of the stomach to the beginning of the large intestine (cecum). It plays a crucial role in the digestion and absorption of nutrients from food. The small intestine is divided into three parts: the duodenum, jejunum, and ileum.

1. Duodenum: This is the shortest and widest part of the small intestine, approximately 10 inches long. It receives chyme (partially digested food) from the stomach and begins the process of further digestion with the help of various enzymes and bile from the liver and pancreas.
2. Jejunum: The jejunum is the middle section, which measures about 8 feet in length. It has a large surface area due to the presence of circular folds (plicae circulares), finger-like projections called villi, and microvilli on the surface of the absorptive cells (enterocytes). These structures increase the intestinal surface area for efficient absorption of nutrients, electrolytes, and water.
3. Ileum: The ileum is the longest and final section of the small intestine, spanning about 12 feet. It continues the absorption process, mainly of vitamin B12, bile salts, and any remaining nutrients. At the end of the ileum, there is a valve called the ileocecal valve that prevents backflow of contents from the large intestine into the small intestine.

The primary function of the small intestine is to absorb the majority of nutrients, electrolytes, and water from ingested food. The mucosal lining of the small intestine contains numerous goblet cells that secrete mucus, which protects the epithelial surface and facilitates the movement of chyme through peristalsis. Additionally, the small intestine hosts a diverse community of microbiota, which contributes to various physiological functions, including digestion, immunity, and protection against pathogens.

Fructose intolerance, also known as hereditary fructose intolerance (HFI), is a genetic disorder that affects the body's ability to metabolize the sugar called fructose, which is found in fruits, vegetables, and processed foods. It is caused by a deficiency of an enzyme called aldolase B, which is necessary for the breakdown and absorption of fructose in the liver.

When individuals with fructose intolerance consume food or drinks containing fructose, the undigested fructose accumulates in the bloodstream and gets absorbed by other organs, leading to a range of symptoms such as abdominal pain, bloating, diarrhea, vomiting, and low blood sugar. Prolonged exposure to high levels of fructose can also cause liver damage, kidney failure, and growth retardation in children.

The diagnosis of fructose intolerance is usually made through a combination of clinical symptoms, genetic testing, and a fructose tolerance test. The treatment for fructose intolerance involves avoiding foods and drinks that contain fructose or limiting their consumption to very small amounts. In some cases, supplementation with enzyme replacement therapy may be recommended.

Beta-galactosidase is an enzyme that catalyzes the hydrolysis of beta-galactosides into monosaccharides. It is found in various organisms, including bacteria, yeast, and mammals. In humans, it plays a role in the breakdown and absorption of certain complex carbohydrates, such as lactose, in the small intestine. Deficiency of this enzyme in humans can lead to a disorder called lactose intolerance. In scientific research, beta-galactosidase is often used as a marker for gene expression and protein localization studies.

Orthostatic intolerance is a condition in which an individual experiences lightheadedness, dizziness, or fainting when standing or maintaining an upright position for extended periods. It is caused by an abnormal physiological response to gravity and results in inadequate blood flow to the brain upon standing.

The medical definition of orthostatic intolerance includes symptoms that are exacerbated by upright posture and relieved by recumbent (lying down) position. The underlying mechanisms involve dysfunction in the autonomic nervous system, which controls involuntary bodily functions such as heart rate, blood pressure, and vasoconstriction.

Orthostatic intolerance can be a symptom of various medical conditions, including postural orthostatic tachycardia syndrome (POTS), neurogenic orthostatic hypotension, and other autonomic disorders. Proper diagnosis and management require a thorough evaluation by a healthcare professional to identify the underlying cause and develop an appropriate treatment plan.

Lactose synthase is an enzyme composed of two subunits: a regulatory subunit, β-1,4-galactosyltransferase (β-1,4-GT), and a catalytic subunit, α-lactalbumin. This enzyme plays a crucial role in lactose biosynthesis during milk production in mammals. By catalyzing the transfer of a galactose molecule from UDP-galactose to glucose, lactose synthase generates lactose (or milk sugar), which is essential for providing energy and growth to newborns. The activity of lactose synthase is primarily regulated by α-lactalbumin, which modifies the substrate specificity of β-1,4-GT, allowing it to use glucose as an acceptor instead of other glycoconjugates.
