Lymphohypoplastic diathesis ranks second in the group of allergic and other protracted diseases. Children with lymphohypoplastic diathesis appear to be pale, apathetic, easy to feel fatigue and they cannot tolerate long-term and severe irritation.
These children usually have excess body weight, tissue and muscle tension is reduced, the skin is loose. Subcutaneous fat is excessively developed, and unevenly distributed (predominantly on the abdomen and thighs). Diffuse hyperplasia of lymphoid tissue is typical for lymphohypoplastic diathesis: propensity to lymph nodes hyperplasia, thymus, tonsils, there is proliferation of adenoid tissue. Thymus can be of significant size, causing hoarseness, noisy breathing, throwing of the head during sleep, respiratory distress, status astmaticus, asphixia epizodes, and seizures. Such children refer to sickly kids. They often show skin changes, the tendency to frequent and prolonged respiratory infections developing neurotoxicity and violations of microcirculation disturbance. Symptoms nanifested to the high extent during lymphohypoplastic diathesis are -sually developed at the age of 3-6 years. Later on, manifestations of diathesis gradually get smooth or resolve, although children may have
delay in sexual development. It should be kept in mind that children with lymphohypoplastic diathesis are in the high risk group of infant death syndrome, infection-dependent bronchial asthma and autoimmune diseases.
