Patient-Friendly Explanation

Hyperphagia is a condition where a person has an abnormally strong drive to eat, often feeling they cannot control how much they consume. Unlike normal hunger, it persists even after eating a full meal. Hyperphagia may be caused by hormonal imbalances, certain genetic conditions, or as a side effect of some medications.

Clinical Definition

Hyperphagia is characterised by excessive food consumption beyond homeostatic energy needs, driven by dysregulation of appetite-control pathways in the hypothalamus. It differs from polyphagia (excessive hunger) in that hyperphagia specifically refers to the behavioural act of overeating. It is a hallmark feature of Prader-Willi Syndrome and can also occur with hypothalamic lesions, certain antipsychotic medications, and leptin deficiency.

Why It Matters

Identifying and addressing hyperphagia is essential for effective weight management because willpower alone cannot overcome a biological drive to overeat. NuLifeCare Singapore’s approach includes medical assessment for underlying causes of hyperphagia and targeted interventions such as GLP-1 receptor agonists that help regulate appetite at the neurological level.
