Having intense, hard-to-control hunger, constantly feeling hungry, and having severe preoccupation with food can cause distress and make it difficult to function.

If this describes you or your child, you’re not the only one, and it’s not your fault. Intense hunger and obesity from a very early age are two symptoms of a few rare genetic diseases of obesity. These genetic diseases – Bardet-Biedl syndrome (BBS), pro-opiomelanocortin (POMC) deficiency, proprotein convertase subtilisin/kexin type 1 (PCSK1) deficiency and leptin receptor (LEPR) deficiency – cause the signals that turn off hunger in the brain to stop working properly.
