In medicine, polyphagia (sometimes known as hyperphagia) is a medical sign meaning excessive hunger and abnormally large intake of solids by mouth. Disorders such as diabetes, Kleine-Levin Syndrome (a malfunction in the hypothalamus), the genetic disorders Prader-Willi Syndrome and Bardet Biedl Syndrome can cause hyperphagia (compulsive hunger).[1] It is associated with excessive hunger or increased appetite.[2] It derives from the Greek words πολύς (polys) which means "very much", and φαγῶ (phago) meaning "eat".
Causes[]
Causes of increased appetite include:[3]
- Anxiety
- Certain drugs
- Diabetes mellitus
- Hyperthyroidism
- Hypoglycemia
- Premenstrual syndrome
- Prader-Willi syndrome
- Bulimia
- Graves' disease
Diabetic ketoacidosis[]
Polyphagia usually occurs early in the course of diabetic ketoacidosis.[4] However, once insulin deficiency becomes more severe and ketoacidosis develops, appetite is suppressed.[5]
In biology[]
In biology, "polyphagia" is a type of phagy, referring to an animal that feeds on many kinds of food.
