[Classification and pathophysiology of symptomatic obesity].

Symptomatic obesity was classified by 1) endocrine obesity, 2) central nerve-related obesity, 3) genetic syndrome with obesity and 4) drug-induced obesity. Pathogenesis and pathophysiology of the diseases which induce symptomatic obesity, were briefly described. The origins of hyperphagia and obesity in these diseases have not yet clarified. Gene abnormalties of the genetic syndrome with obesity will be elucidated in near future by the rapidly progress of molecular biological techniques.
