Colored bands are obtained as final result, and depending on the different combination, it would be possible to determine whether the patient is lactose intolerant. This test allows a noninvasive definitive diagnostic. Management edit When lactose intolerance is due to secondary lactase deficiency, treatment of the underlying disease may allow lactase activity to return to normal levels. 5 In people with coeliac disease, lactose intolerance normally reverts or improves several months after starting a gluten-free diet, but temporary dietary restriction of lactose may be needed. 4 45 people with primary lactase deficiency cannot modify their bodys ability to produce lactase. 1 In societies where lactose intolerance is the norm, it is not considered a condition that requires treatment. However, where dairy is a larger component of the normal diet, a number of efforts may be useful. There are four general principles in dealing with lactose intolerance: avoidance of dietary lactose, substitution to maintain nutrient intake, regulation of calcium intake, and use of enzyme substitute. 41 Regular consumption of dairy food by lactase deficient individuals may also reduce symptoms of intolerance by promoting pijn colonic bacteria adaptation. 46 dietary avoidance edit The primary way of managing the symptoms of lactose intolerance is to limit the intake of lactose to a level that can be tolerated. 47 Lactase deficient individuals vary in the amount of lactose they can tolerate, 1 and some report that their tolerance varies over time, depending on health status and pregnancy. 48 49 However, as a rule of thumb, people with primary lactase deficiency and no small intestine injury are usually able to consume at least 12 grams of lactose per sitting without symptoms, or with only mild symptoms, with greater amounts tolerated if consumed with.

The bacteria in the colon, mixed with the lactose, cause acidity in stools. Stools passed after the ingestion of the lactose are tested for level of acidity. If the stools are acidic, the infant is intolerant to lactose. 40 Stool pH in lactose intolerance is less than.5. Intestinal biopsy edit An intestinal biopsy can confirm lactase deficiency following discovery of elevated hydrogen in the hydrogen breath test. 41 Modern techniques have enabled betekent a bedside test, identifying presence of lactase enzyme on upper gastrointestinal endoscopy instruments. 42 However, for research applications such as mrna measurements, a specialist laboratory is required. Stool sugar chromatography edit Chromatography can be used to separate and identify undigested sugars present in faeces. Although lactose may be detected in the faeces of people with lactose intolerance, this test is not considered reliable enough to conclusively diagnose or exclude lactose intolerance. Citation needed genetic verdwijnt diagnostic edit genetic tests may be useful in assessing whether a person has primary lactose intolerance. 43 Lactase activity persistence in adults is associated with two polymorphisms : C/T 13910 and G/A 22018 located in the mcm6 gene. 44 These polymorphisms may be detected by molecular biology techniques at the dna extracted from blood or saliva samples; genetic kits specific for this diagnosis are available. The procedure consists of extracting and amplifying dna from the sample, following with a hybridation protocol in a strip.

36 Blood test edit In conjunction, measuring blood glucose level every 10 to 15 minutes after ingestion will show a "flat curve" in individuals with lactose malabsorption, while the lactase persistent will have a significant "top with a typical elevation of 50 to 100, within. However, due to the need for frequent blood sampling, this approach has been largely replaced by breath testing. 37 After an overnight fast, blood is drawn and then 50 grams of lactose (in aqueous solution) are swallowed. Blood is then drawn again at the 30-minute, 1-hour, 2-hour, and 3-hour marks. If the lactose cannot be digested, blood glucose levels will rise by less than 20 mg/dl. 38 Stool acidity test edit This test can be used to diagnose lactose intolerance in infants, for whom other forms of testing are risky or impractical. 39 The infant is given lactose to drink. If the individual is tolerant, the lactose is digested and absorbed in the small intestine; otherwise, it is not digested and absorbed, and it reaches the colon.

(April 2016) to assess lactose intolerance, intestinal function dikke is challenged by ingesting more dairy products than can be readily digested. Clinical symptoms typically appear within 30 minutes, but may take up to two hours, depending on other foods and activities. 34 Substantial variability in response (symptoms of nausea, cramping, bloating, diarrhea, and flatulence) is to be expected, as the extent and severity of lactose intolerance varies among individuals. The next step is to determine whether it is due to primary lactase deficiency or an underlying disease that causes secondary lactase deficiency. 2 Physicians darm should investigate the presence of undiagnosed coeliac disease, crohn disease, or other enteropathies when secondary lactase deficiency is suspected and an infectious gastroenteritis has been ruled out. 2 Lactose intolerance is distinct from milk allergy, an immune response to cow's milk proteins. They may be distinguished in diagnosis by giving lactose-free milk, producing no symptoms in the case of lactose intolerance, but the same reaction as to normal milk in the presence of a milk allergy. A person can have both conditions. If positive confirmation is necessary, four tests are available. 35 Hydrogen breath test edit In a hydrogen breath test, the most accurate lactose intolerance test, after an overnight fast, 25 grams of lactose (in a solution with water) are swallowed. If the lactose cannot be digested, enteric bacteria metabolize it and produce hydrogen, which, along with methane, if produced, can be detected on the patient's breath by a clinical gas chromatograph or compact solid-state detector.

This form of lactose intolerance can occur in both infants and lactase persistent adults and is generally reversible. 27 It may be caused by acute gastroenteritis, coeliac disease, crohn's disease, ulcerative colitis, 28 chemotherapy, intestinal parasites (such as giardia or other environmental causes. Primary congenital alactasia edit Primary congenital alactasia, also called congenital lactase deficiency, is an extremely rare, autosomal recessive enzyme defect that prevents lactase expression from birth. 2 3 people with congenital lactase deficiency cannot digest lactose from birth, so cannot digest breast milk. This genetic defect is characterized by a complete lack of lactase (alactasia). About 40 cases have been reported worldwide, mainly limited to finland. 3 Before the 20th century, babies born with congenital lactase deficiency often did not survive, 2 but death rates decreased with soybean -derived infant formulas and manufactured lactose-free dairy products. 33 diagnosis edit This section needs more medical references for verification or relies too heavily on primary sources.

18 The lactase deficiency also could be linked to certain heritages. Approximately 75 percent of African Americans, native americans, and Jewish Americans are lactose intolerant, as are 90 percent of Asian Americans and 53 percent of Mexican Americans. 19 20 Analysis of the dna of 94 ancient skeletons in Europe and Russia concluded that the mutation for lactose tolerance appeared about 4,300 years ago and spread throughout the european population. 21 Some human populations have developed lactase persistence, in which lactase production continues into adulthood probably as a response to the benefits of being able to digest milk from farm animals. 3 Some have argued that this links intolerance to natural selection favoring lactase-persistent individuals, but it is also consistent with a physiological response to decrease lactase production when it is not needed in cultures in which dairy products are not an available food source. 22 Although populations in Europe, india, arabia, and Africa were first thought to have high rates of lactase persistence because of a single mutation, lactase persistence has been traced to a number of mutations that occurred independently. 23 Different alleles for lactase persistence have developed at least three times in East African populations, with persistence extending from 26 in Tanzania to 88 in the beja pastoralist population in Sudan. Lactose intolerance is classified according to its causes as: Primary hypolactasia edit Primary hypolactasia, or primary lactase deficiency, is genetic, only affects adults, and is caused by the absence of a lactase persistence allele. In individuals without the lactase persistence allele, less lactase is produced by the body over time, leading to hypolactasia in adulthood. 2 25 The frequency detoxen of lactase persistence, which allows lactose tolerance, varies enormously worldwide, with the highest prevalence in Northwestern Europe, declines across southern Europe and the middle east and is low in Asia and most of Africa, although it is common in pastoralist populations. 3 26 Secondary hypolactasia edit secondary hypolactasia or secondary lactase deficiency, also called acquired hypolactasia or acquired lactase deficiency, is caused by an injury to the small intestine. zit er lactose in ei

1 The dikke severity of symptoms typically increases with the amount of lactose consumed; most lactose-intolerant people can tolerate a certain level of lactose in their diets without ill effects. 13 14 Lactose intolerance is a consequence of lactase deficiency, which may be genetic ( primary hypolactasia and primary congenital alactasia ) recepten or environmentally induced ( secondary or acquired hypoalactasia ). In either case, symptoms are caused by insufficient levels of lactase in the lining of the duodenum. Lactose, a disaccharide molecule found in milk and dairy products, cannot be directly absorbed through the wall of the small intestine into the bloodstream, so, in the absence of lactase, passes intact into the colon. Bacteria in the colon can metabolise lactose, and the resulting fermentation produces copious amounts of gas (a mixture of hydrogen, carbon dioxide, and methane ) that causes the various abdominal symptoms. The unabsorbed sugars and fermentation products also raise the osmotic pressure of the colon, causing an increased flow of water into the bowels (diarrhea). 15 16 The lct gene provides the instructions for making lactase. The specific dna sequence in the mcm6 gene helps control whether the lct gene is turned on or off. 17 At least several thousand years ago, some humans developed a mutation in the mcm6 gene that keeps the lct gene turned on even after breast feeding is stopped. 18 people who are lactose intolerant do not have this mutation. The lct and mcm6 genes are both located on the long arm (q) of chromosome 2 in region. The locus can be expressed as 2q21.

3 Onset is typically in late childhood or early adulthood. 1 The ability to digest lactose into adulthood evolved in several human populations independently probably as an adaptation to domestication of dairy animals 10,000 years ago. 9 3 10 Contents Terminology edit lactose intolerance primarily refers to a syndrome having one or more symptoms upon the consumption of food substances containing lactose. Individuals may be lactose intolerant to varying degrees, depending on the severity of these symptoms. "Lactose malabsorption" refers to the physiological concomitant of lactase deficiency (i.e., the body does not have sufficient lactase capacity yakult to digest the amount of lactose ingested). 2 Hypolactasia (lactase deficiency) is distinguished from alactasia (total lack of lactase a rare congenital defect. 11 Lactose intolerance is not an allergy, because it is not an immune response, but rather a sensitivity to dairy caused by lactase deficiency. Milk allergy, occurring in only 4 of the population, is a separate condition, with distinct symptoms that occur when the presence of milk proteins trigger an immune reaction. 12 Signs and symptoms edit The principal symptom of lactose intolerance is an adverse reaction to products containing lactose (primarily milk including abdominal bloating and cramps, flatulence, diarrhea, nausea, borborygmi, and vomiting (particularly in adolescents ). These appear one-half to two hours after consumption.

Secondary lactose intolerance is due to injury to the small intestine such as from infection, celiac disease, inflammatory bowel disease, or other diseases. 1 4, developmental lactose intolerance may occur in premature babies and usually improves over a short period of time. 1 Congenital lactose intolerance is an extremely rare genetic disorder in which little or no lactase is made from birth. 1 diagnosis may be confirmed if symptoms resolve following eliminating lactose from the diet. 1 Other supporting tests include a hydrogen breath test and a stool acidity test. 1 Other conditions that may produce similar symptoms include irritable bowel syndrome, celiac disease, and inflammatory bowel disease. 1 Lactose intolerance is different from a milk allergy. 1 Management is typically by decreasing the amount of lactose in the diet, taking lactase supplements, or treating the underlying disease. 1 5 people are usually able to drink at least one cup of milk per sitting without developing significant symptoms, with greater amounts tolerated if drunk with a meal or throughout the day. 1 6 The exact number of adults with lactose intolerance is unknown. 7 One estimate puts the average at 65 of the global population. 8 Rates of lactose intolerance vary between regions, from less harde than 10 in Northern Europe to as high as 95 in parts of Asia and Africa.

Not to be confused with, milk allergy. Lactose intolerance is a condition in which people have symptoms due to the decreased ability to digest lactose, a sugar found in milk products. 1, those affected vary in the amount of lactose they can tolerate before symptoms develop. Symptoms eten may include abdominal pain, bloating, diarrhea, gas, and nausea. 1, these symptoms typically start between one half and two hours after drinking milk or eating milk products. Severity depends on the amount a person eats or drinks. 1, it does not cause damage to the gastrointestinal tract. 2, lactose intolerance is due to the lack of enzyme lactase buikvet in the small intestines to break lactose down into glucose and galactose. 3, there are four types: primary, secondary, developmental, and congenital. 1, primary lactose intolerance occurs as the amount of lactase declines as people age.
