Effects of antipsychotics on fat deposition and changes in leptin and insulin levels

Patients first receiving antipsychotic drugs experience substantial deposition of both subcutaneous and intra-abdominal fat, reflecting a loss of the normal inhibitory control of leptin on body mass. Along with fat deposition, the increase in levels of fasting lipids and in non-fasting glucose may provide early signs of drug-induced progression towards the metabolic syndrome.
