HYPERPHAGIA
Hyperphagia here is a hypothalamic problem, not a willpower problem.
Satiety is delayed or incomplete. Miller's phase 3 had a median onset of 8 years (often 5 to 13). Some adults later reach phase 4 and can feel full. Most do not. A 2025 US drug approval does not replace food locks.
MECHANISM
Satiety is often incomplete
Thinking about food can take up a lot of the day. Sneaking is common and is not a character issue. People whose weight is under control, after a large binge, are the group gastric alerts keep naming.
One US approval in 2025. Food storage still matters.
VYKAT XR is the first US drug indicated for hyperphagia in PWS, from age 4. It needs a clinician who knows this syndrome. Carbetocin missed every endpoint in a 175-person phase 3 trial and development stopped.
