Etymology and pronunciation
The word polyphagia (, from the Greek words πολύς (polys), "very much" or "many", and φᾰ́γω (phago), "eating" or "devouring".
Underlying conditions and possible causes
Polyphagia is one of the most common symptoms of diabetes mellitus. It is associated with hyperthyroidism and endocrine diseases, e.g., Graves' disease, and it has also been noted in Prader–Willi syndrome and other genetic conditions caused by chromosomal anomalies. It is only one of several diagnostic criteria for bulimia and is not by itself classified as an eating disorder. As a symptom of Kleine–Levin syndrome, it is sometimes termed megaphagia.[3]
Knocking out vagal nerve receptors has been shown to cause hyperphagia.[4]
Changes in hormones associated with the female menstrual cycle can lead to extreme hunger right before the period. Spikes in estrogen and progesterone and decreased serotonin can lead to cravings for carbohydrates and fats.[5]
