Lactose intolerance is often confused with a dairy allergy and end up eliminating some foods unnecessarily from their diet.

Food allergies are caused by the body's reaction to the protein found in a food and in case of dairy products, that means the whey or casein. When allergic situation, occure the body sends out a whole drama of reactions to fend off what it perceives to be invader. This cause symptoms beyond intestinal distress.

But, lactose intolerance is simply a case of limited production of the enzyme (lactase) that breaks down the double sugar, lactose. Enzyme is normally produced in the lining of the small intestine.When low levels occur because of genetics, alcoholism, increasing age,intestinal parasites, use of certain antibiotics,cystic fibrosis, some cancer treatments, or because of trauma to or inflammation of intestinal lining.

Lactose intolerance could be temporary situation with some people. As example would be someone with celiac disease who produces inadequate lactase while consuming gluten. When they become gluten-free and the intestines return to normal, lactose intolerance vanish.

Causes of lactose intolerance symptoms - bloating and gas: When the lactase enzyme is in low level, lactose does not broke down and travels into the colon. There it is consumed by the bacteria that live there, what results in gas production. With some people, undigested lactose in the lower bowel is causing diarrhea.
