GLP-1RAs are safe and effective weight loss treatments for individuals with obesity and mental illness exerting a positive effect on mental state and quality of life. There is a need for RCTs with larger sample sizes, a longer treatment duration and longer follow-up periods to evaluate the long-term effect of GLP-1RAs. It would be of great interest to conduct studies investigating the use of GLP-1RAs with the purpose to treat mental illness in order to directly assess their use in improving mental health.
