Hunger Overview

Abnormal hunger or excessive eating, also called polyphagia or hyperphagia, can be the symptom of various disorders. Simple causes relate to low food intake, over-exercising, or practical difficulties with food. Psychological eating may occur in various eating disorders.

Organic disease can also cause hunger and excessive eating behavior, especially two common diseases: diabetes and hyperthyroidism. Hunger is a classic sign of undiagnosed diabetes, where a person is usually eating voraciously while still losing weight! Another possibility is hyperthyroidism (excessive thyroid hormone) which causes the body’s metabolism to speed up, resulting in weight loss and increased demand for food.
