Lactase deficiency or lactose intolerance in children is a serious disorder. In adults, it manifests a variety of unpleasant symptoms, for which a person may not even realize that he enzyme deficiency, writing off its malaise to other diseases, such as allergies, gastritis, gastric ulcer and duodenal ulcers, nervous disorders, goiter

Etiology and pathogenesis
Lactose intolerance is widespread in the world, although its incidence in different countries is very different. Lactase deficiency can be congenital or acquired.
Congenital lactase deficiency develops as genetically determined reduction of the enzyme lactase in the intestinal lumen and divided by the total absence of the enzyme and partial, which determines the clinical picture of a pathological condition.
Acquired lactase deficiency is divided into primary and secondary.
Primary is associated with reduced activity of the enzyme itself - the so-called constitutional lactase deficiency.
Resale associated with damage to the enterocytes of the intestine caused by both acute and chronic conditions, such as celiac disease or intestinal infections
Celiac disease - not quite intestinal pathology
. Secondary lactase deficiency can cause prolonged starvation, and unbalanced diet.
Clinical symptoms and diagnosis
Full lactase deficiency in adults is most often manifested osmotic diarrhea - after ingestion of foods containing lactose, appears loose stools, frequent, frothy, sour smell.
However, more often lactase deficiency is partial and its degree of manifestation is directly proportional to the lactase deficiency in the lumen of the intestine, therefore the symptoms can be different - from mild bloating
Flatulence - when you need to worry about?
To which many do not pay attention to severe abdominal distention
Bloating - if you are bursting inside
and spilled abdominal pain.
Diagnosis lactase deficiency presents some difficulties due to the lack of vigilance among doctors, especially when the patient is no clear link between the intake of dairy products and the development of characteristic symptoms.
Lactase deficiency can be confirmed clinically by dietodiagnostiki when the patient to the exclusion of lactose product feels good, and vice versa, for a load receiving dairy products starting to feel much worse.
Used method for determining the pH of feces, which is normally above 5, 5, and decreases with lactase deficiency. A common method of diagnosis is to identify the carbohydrates in the feces. Normally, in adults, they are absent.
It is used as the method of determination of labeled carbon dioxide in the exhaled air, which detects the activity of lactose fermentation microflora after the use of the patient labeled lactose.
Treatment lactase deficiency
Treatment of lactase deficiency in adults is the correct diet.
In severe, you can use no more than one gram of lactose per day, and with moderate - to ten. When selecting products, you need to consider two measures: the lactose content in them, and the total amount of which is to be consumed.
The dishes that contain lactose, are better absorbed in combination with other products, as more food passes more slowly through the intestinal tube thus lactase molecules have more time to break down lactose.
It should also be borne in mind that products having contrasting temperatures cause more discomfort, so the preference should be given to warm food.
The large amount of lactose present in milk and milk products, but in small quantities, which is sufficient for the development of symptoms, lactose contained in other foods such as meats, chocolates, sweetened condensed milk, semi-finished products, bakery products and concentrates.
