Polyphagia and binge eating are related conditions characterized by excessive food intake, but they have distinct features.

Polyphagia

• Definition: Excessive hunger or increased appetite, often accompanied by a persistent urge to eat large amounts of food and difficulty feeling satiated.
• Common Causes:
• Diabetes mellitus: Uncontrolled blood sugar levels leading to excessive hunger.
• Hyperthyroidism: Increased metabolic rate resulting in heightened appetite.
• Stress and anxiety: Emotional factors driving overeating.
• Certain medications: Drugs like corticosteroids or antipsychotics.
• Prader-Willi syndrome: A genetic condition causing chronic hunger and overeating.

Binge Eating Disorder (BED)

  • Consuming food even when not physically hungry.
  • Experiencing guilt, shame, or disgust after bingeing.
• Associated Conditions:

  • Depression and anxiety: Psychological factors often co-occur with BED.
  • Low self-esteem: Negative self-perception commonly accompanies this disorder.
