What Is lactose Intolerance ?
Lactose intolerance is caused by the body ‘s inability to digest milk carbohydrate, or lactose. In decree to break lactose down into simple sugars, or monosaccharides, the body must produce the enzyme called “ lactase, ” which is produced in the small intestine. Without lactase, the lactose from milk products is ineffective to be digested. This causes the symptoms of gas, cramps and diarrhea that many people experience after eat or drink in dairy products.
lactose intolerance is a condition that normally develops over time. After a person reaches about 2 years of age, the body begins to produce less of the enzyme lactase. The reasons for this are not silent. It is rare for an baby to be born lactose intolerant, which can cause vomit and a “ failure to thrive. “ Symptoms of lactose intolerance can appear years after childhood .

People of northerly European and some Middle Eastern ( Bedouins, Saudis, Yemenis ) descents have little incidence of lactose intolerance. geographic regions seem to play a function in the incidence of lactose intolerance. Descendants of people from northerly Europe, for exemplar, have been dependent on milk products as a food source in their geographic region for a few thousand years.

Blood is drawn to measure the current blood glucose level. future, the patient will drink a fluid that contains up to 50 grams of lactose. For the future two hours, more blood samples are taken to measure lineage glucose levels. If the lactose is being broken down in the body by the enzyme lactase, the blood glucose horizontal surface will rise. If the blood glucose flush does not rise, that means that the lactose is not being broken down into simple sugars and the affected role has lactose intolerance .
The hydrogen breath test. This test is identical exchangeable to the lactose intolerance test and might be done on children adenine young as 6 months arsenic well as adults. After fasting for several hours, the patient will exhale in to a mouthpiece connected to a foil bag that looks like a balloon.

More hint samples will be taken at assorted intervals for up to 6 hours .
normally, there is no hydrogen confront in a person ‘s hint. When a lactose intolerant person ingests lactose, it stays in their intestines and ferments, ultimately producing hydrogen gas. consequently, if hydrogen is present in the breath samples taken after drinking the lactose, the diagnosis of lactose intolerance can be made .
The stool acidity test. This examination is normally done on infants and little children. It is noninvasive and presents no problems, such as dehydration caused by diarrhea, from ingesting boastfully amounts of lactose. A stool sample is collected and tested for lactic acid, glucose and other short-chain fatso acids that may be give when lactose remains undigested by the body .
