Oligotrophy - chronic frustration of the delivery, described a various degree of loss of mass of a body. As a rule, an oligotrophy children of early age suffer.

Etiology, pathogenesis. Distinguish the congenital (prenatal) got oligotrophy. The congenital oligotrophy is caused by diseases of mother more often or bound to a fetal hypoxia, an infection of a fetus, chromosomal mutations. Among the reasons got oligotrophies allocate exogenous and endogenous. To the first carry alimentary factors (a hypogalactia at mother, incorrectly calculated ration at artificial feeding, unilateral feeding, etc.), the pylorostenosis and a pylorospasm, medicinal poisonings (hypervitaminosis D, etc.), infections of a gastrointestinal tract, disadvantages of leaving, a regimen, education, etc. the Endogenous reasons of an oligotrophy can be developmental anomalies of a gastrointestinal tract and other organs, lesions of the central nervous system, hereditary anomalies of a metabolism and immune scarce conditions, endocrine diseases, etc.

In a basis of a pathogenesis of an oligotrophy depression of recycling of alimentary substances with disturbance of processes of digestion, an absorption and their mastering under influence of various factors lays.

Distinguish 1 and 2 degrees of gravity of an oligotrophy.

Clinical picture. The oligotrophy of 1 degree is characterized by loss of mass of a body no more than on 20 % from forced on age. The hypodermic fatty layer on a stomach becomes more thin.

At an oligotrophy of 2 degrees loss of mass of a body makes 25-30 % in comparison with age norm. The hypodermic is kept only on the face, it is especially refined on a stomach and extremities. The skin dry, easily gathers in cords, here and there hangs down. Backlog in body height is observed, appetite decreases, the child becomes irritable, loses the skills got earlier, the thermoregulation is broken.
