Excessive hunger commonly seen in diabetes?

Explanation:
When insulin is deficient or its action is impaired, glucose stays in the blood but can’t enter many cells. Cells sense an energy shortage and trigger hunger signals, leading to excessive appetite (polyphagia) despite high blood glucose. The other symptoms—excessive urination and thirst—come from osmotic effects of high glucose in the urine, causing dehydration rather than hunger. Anaphylaxis is unrelated to glucose metabolism and presents with other acute symptoms, not increased appetite.
