increased desire to eat. Could be caused by physical exertion or dieting and alleviated after eating. Other reasons could be premenstrual syndrome, stress, anxieties, reaction to medications (corticosteroids, cyproheptadine, tricyclic antidepressants, etc). Significantly increased appetite over a prolonged period, especially if it is accompanied by additional symptoms, could be a symptom of a serious illness, such as diabetes or hyperthyroidism.
