Obesity due to SIM1 deficiency is a rare genetic disorder caused by a mutation in the SIM1 gene. This gene is responsible for the production of the protein SIM1, which plays a role in the regulation of appetite and energy balance. People with this disorder have an increased appetite and difficulty controlling their weight, leading to obesity. Treatment typically involves lifestyle changes such as diet and exercise, as well as medications to help control appetite and reduce weight.

Symptoms of obesity due to SIM1 deficiency can include excessive weight gain, increased appetite, and difficulty losing weight despite diet and exercise. Other symptoms may include fatigue, sleep disturbances, and mood changes. In some cases, individuals with SIM1 deficiency may also experience delayed puberty, infertility, and/or abnormal glucose metabolism.
