What is the term for excessive ingestion of food?

The term "polyphagia" refers to excessive ingestion of food. This condition is not just about eating large amounts at one time but can also encompass an overwhelming or insatiable appetite that drives an individual to consume more food than what is considered normal. Polyphagia is often associated with certain medical conditions, such as diabetes, where the body struggles to utilize nutrients effectively, leading to increased hunger. It is important to differentiate this term from others related to eating behaviors or conditions.

For example, anorexia refers to a significant loss of appetite or an intense fear of gaining weight, often leading to restrictive eating. Bulimia involves cycles of binge eating followed by compensatory behaviors such as vomiting or excessive exercise to prevent weight gain. Cachexia describes a state of severe weight and muscle loss often associated with chronic illness, rather than excessive food intake. Understanding these distinctions helps in grasping the broader context of appetite and eating disorders in health science.
