Why am I always hungry?

Constant hunger usually has lifestyle roots before medical ones. The big four: meals built on refined carbs that spike and crash blood sugar, leaving you hungry an hour later; not enough protein and fiber, the two nutrients that actually signal fullness; short sleep, which measurably raises hunger hormones the next day; and stress, which drives eating through cortisol. Thirst masquerading as hunger is common too. The fix is mechanical: anchor meals with protein and fiber, drink water before assuming hunger, sleep seven-plus hours, and watch whether hunger shrinks within a week or two. That experiment answers most cases. When hunger is a symptom instead: hunger paired with excessive thirst, frequent urination, and weight loss is the diabetes triad - get a blood sugar test promptly. An overactive thyroid can drive appetite with weight loss, shakiness, and a racing heart - also a blood test. Some medications, especially steroids and some psychiatric drugs, genuinely increase appetite. And in pregnancy, rising hunger is normal physiology. Pymander is a free AI doctor, 24/7 by text.
