History(rate of weight gain, dietary history, caloric expenditure, prescribed diet for successful weight loss, recently quit smoking, endocrine features,
cold, constipation, hair change, virilization, striae, buffalo hump).
etiology of obesity, dietary and caloric expenditure history, family history and exploration of socioeconomic factors and medications(including many anti- psychotic and antidepressant medications, insulin, sulfonylureas, anticonvulsants, beta blockers, and cyproheptadine). Endocrine causes are rare and include Cushing’s disease, hypothyroidism, or hypothalamic disorders. Routine testing for endocrine causes is not recommended unless the history, physical examination, and distribution of adipose tissue support the endocrine diagnosis. When patients claim they are not los- ing weight on a diet below 1200 calories per day, it almost invariably means they are not keeping an accurate record of their caloric intake.
