Lactase deficiency:

Lactose intolerance ( )

Lactose intolerance is a condition in which the patient experiences stomach aches or diarrhea after consuming dairy products, due to a lack of the enzyme lactase in the intestines.

Full Description

Lactose intolerance is a common condition in which there is a lack of the enzyme lactase in the intestines, resulting in lack of proper digestion of lactose found in dairy products. Children possess large amounts of lactase, which allows the digestion of their mother’s milk. However, after being weaned, levels drop steadily, leading to intolerance for dairy products. About 15% of people in Central Europe are affected, while 95% in Asia are.

Medical Conditions

An intolerance presents itself as strong stomach aches, flatulance, and diarrhea after consuming milk or dairy products. Certain types of hard cheeses, butter, and lactose-free products can be tolerated well.


Treatment is simple and consists of a lactose-free diet. More and more supermarkets offer lactose-free products. If consumption of dairy cannot be avoided, you can take the enzyme lactase in a medicated form.
