Summary

Polyphagia is the medical term for excessive hunger or eating. It is a common symptom of diabetes but may also indicate other conditions.

Excessive hunger is not always easily explained because all individuals have unique caloric needs based on a variety of factors, including age, body size and activity level. People who are very hungry after an extended period without food, and those who have always had a large appetite, do not have polyphagia.

Polyphagia is Diabetes mellitus is a disorder in the body's ability to break down blood sugar (glucose).often an acute symptom caused by hypoglycemia (low blood glucose), a condition that affects many people with diabetes. Other causes of polyphagia may include anxiety, eating disorders, hyperthyroidism and pregnancy.

Unexplained weight loss may accompany polyphagia in people with type 1 diabetes. However, many people with type 2 diabetes who have polyphagia gain weight after overeating. Individuals who feel compelled to overeat are advised to contact their physician.

Diagnosis of polyphagia begins with a medical history and physical examination. Treatment of polyphagia is directed at its cause. For example, an individual with diabetes may be prescribed exercise, diet and possibly insulin or other medication.
