In children and adolescents obesity can be:
- independent primary disease (primary alimentary obesity, exogenous-constitutional obesity);
- cerebral* (possible reasons – cerebral tumors and infectious diseases of the brain);
- endocrine* (possible reasons – thyroid diseases, dysfunction of the adrenal gland or hypothalamus-pituitary system);
- genetic** (possible reasons – Prader-Willi syndrome, Laurence-Moon-Bardet-Biedl syndrome, Cohen syndrome).
*When eliminating symptoms of endocrine and cerebral diseases, body weight gradually normalizes in children and adolescents under 12 years.
**Obesity, arising due to genetic predisposition requires a long-term complex and continuous treatment.
