In medicine
In medicine, polyphagia (sometimes known as hyperphagia) is a medical sign meaning excessive hunger and abnormally large intake of solids by mouth. It can be caused by disorders such as diabetes, Kleine-Levin syndrome (a malfunction in the hypothalamus), and the genetic disorders Prader-Willi syndrome and Bardet-Biedl syndrome. Knocking out vagal nerve receptors has been shown to cause hyperphagia.
