hyperphagia

PRONUNCIATION:
(hy-puhr-FAY-jee-uh)

MEANING:
noun: Compulsive overeating.

ETYMOLOGY:
From Greek hyper- (over) + -phagia (eating). Earliest documented use: 1941.

NOTES:
Before winter denning, a bear’s favorite type of food is simply “Yes!” Human hyperphagia can have medical causes, including damage to the hypothalamus, which helps regulate hunger and satiety. It can be a symptom, not a character flaw; judgment need not be on the menu.

In this sense, a synonym is polyphagia. But if someone overeats many different kinds of food, polyphagia totally applies.

USAGE:
“Then in the fall, the animals transition into hyperphagia, when ‘pretty much all their energy is devoted to eating as much as possible,’ Perry says.”
Melissa Hobson; Hibernating Bears Could Hold a Clue to Treating Diabetes; National Geographic (Washington, DC); Sep 27, 2022.

A THOUGHT FOR TODAY:
Bullets cannot be recalled. They cannot be uninvented. But they can be taken out of the gun. -Martin Amis, novelist (25 Aug 1949-2023)
