Hyperphagia

Hyperphagia is the medical term for an abnormally strong and persistent feeling of hunger that does not go away even after eating. It can be caused by hormone imbalances, certain medications, or genetic conditions and often contributes to weight gain.

Hyperphagia is characterised by excessive food intake driven by dysregulation of appetite-controlling hormones such as ghrelin, leptin, and insulin. It is a hallmark feature of Prader-Willi syndrome and can also occur secondary to hypothalamic lesions, certain antipsychotic medications, and insulin-induced hypoglycaemia. Differentiating pathological hyperphagia from behavioural overeating is essential for appropriate management.

Understanding whether your hunger is driven by biological factors or habits is key to effective treatment. At Accord Medical, Dr. Joseph Wang identifies the root cause of excessive appetite as part of your personalised weight management plan.
