INTOLERÂNCIA À LACTOSE

Abstract

Lactose intolerance (IL) is considered when there is a partial or total deficiency of lactase, which is responsible for hydrolyzing lactose into two sugars. IL can be classified in three ways: the most frequent is primary lactase deficiency, known as adult hypolactasia, secondary lactase deficiency and the third classified as congenital lactose intolerance. Symptoms appear according to the classification and volume of lactose ingested, and may appear through a simple headache, even acute diarrhea and irritating dermatitis. Diagnosis is somewhat invasive. it can be done through three exams. The treatment of IL is quite simple, being necessary to suspend the use of any food that contains a certain amount of lactose, thus avoiding unpleasant symptoms.
