Laktoseintolerans divided into aprimaryand asecondaryshape.
Primary laktoseintoleranscan be congenital or acquired. The congenital form is very rare. Here missing lactase from birth. The acquired form is frequent. Here are lactase present from birth and the first year of life, but then gradually disappear. 5% of the adult Danes have primary occupation laktoseintolerans. In other populations, for example. Africans, Chinese, Eskimos, Indians, etc., much more frequently. Worldwide, approximately. 50% primary occupation laktoseintolerans.
Secondary laktoseintoleransare frequent and caused damage to tarmens mucous membrane. When there is damage to the mucous membranes, for example. seen by glutenintolerance (coeliac disease) or after a gastro-intestinal infection , Lost lactase, and thus the ability to digest lactose. This form is temporary, because the lactase restored with the mucous membranes, where the operative reason treated or disappear by itself.
Symptoms of laktoseintolerans
The symptoms occur only in connection with the consumption of milk. The symptoms debuterer mostly in the 2-4 age is:

The test is positive if the known symptoms occur, and blood sugar does not increase, which it normally would do. The diagnosis can also be made by genetic and a so-calledhydrogen breath test.
Consideration of laktoseintolerans
The treatment is to eliminate lactose, that is. primarily milk from the diet. Since milk is the main source of lime, must also be given calcium supplements. Laktoseindtaget can resume at the secondary laktoseintolerans when the reason for this is processed. Lactose tolerated but only again when the mucous membranes is completely restored, as laktasen is the last fordøjelsesenzym to come back.
Select and complications
The forecast is good. The primary occupation laktoseintolerans the symptoms disappear as soon as the lactose is removed from the diet, and will not come back unless, the person again eat laktoseholdig diet. At the secondary laktoseintolerans disappear laktoseintoleransen when the operative reason treated or disappear by itself.
