Antipsychotics and severe mental illness (SMI) are associated with weight gain, and obesity increases the risks of cardiometabolic disease and premature death. These present management and liability issues for psychiatrists. Physical healthcare for people with SMI is poor, and this may partly be owing to training limitations and lack of proactiveness by psychiatrists. Ethically and legally, psychiatrists have a duty to avoid unnecessary harm and to maintain an acceptable standard of care. This would apply particularly to patients receiving compulsory treatment for their SMI owing to their vulnerability. Discrepancy between psychiatric and non-psychiatric approaches to pharmacological treatment creates ambiguity, and weight gain could demotivate antipsychotic adherence. This article explores how the Mental Health Act could be used to address these issues, and the ethical considerations, and proposes how long-acting glucagon-like peptide-1 receptor agonists could be introduced into existing psychiatric practice as a treatment option for antipsychotic-induced weight gain and obesity in SMI.
