Research indicates that weight loss injections might play a role in enhancing mental health while also curbing appetite.
A study conducted by scientists at the University of Bern, Switzerland, suggests that these appetite-suppressing injections can lead to better mood and overall quality of life, often more so than insulin or other diabetes medications.
Drugs initially designed for diabetes treatment are shifting the landscape of obesity management, with increasing evidence pointing to further health advantages.
According to the Institute for Financial Research, around 13-15% of the workforce in England and Wales is dealing with long-term mental health or behavioral issues, with approximately 2 million individuals in touch with NHS Mental Health Services as of December 2024.
The findings, presented at the European Congress in Malaga, Spain, show that these weight loss injections are both safe and effective even for adults on antipsychotics or antidepressants for severe mental health conditions.
These medications belong to a category known as glucagon-like peptide-1 (GLP-1) receptor agonists, which function by slowing digestion and reducing appetite. The research revealed that treatments including semaglutide (marketed as Ozempic or Wegovy) did not worsen mental health or elevate the likelihood of new mental illness or psychiatric hospitalizations.
Five studies confirmed improvements in mental health and quality of life for individuals with schizophrenia spectrum disorder, major depressive disorder, and bipolar disorder. In adults without mental health issues, weight loss injections proved more beneficial for mental health than traditional diabetes medications.
Dr. Sigrid Bright, a lead researcher from the University of Bern, mentioned that the antidepressant and anti-anxiety effects might stem from the drugs’ anti-inflammatory and antioxidant characteristics, potentially aiding in reducing neuroinflammation.
“This is especially significant for individuals with severe mental disorders, who are three times more likely to be obese compared to the general population,” she pointed out.
Mental health professionals have reacted positively to these findings. Dr. Ed Beveridge, President of the Royal College of Psychiatrists’ Lead for Physical Health, emphasized that many individuals with mental illnesses struggle with weight management for numerous reasons, making it crucial to prioritize their access to suitable medications.
Rachel Hastings-Caplan, Clinical Research Policy Manager for Rethink Mental Illness, remarked that individuals often grapple with the tough decision of taking antipsychotics that help alleviate their mental health symptoms but could negatively affect their physical health due to side effects.
“While this study on weight loss injections is significant and hopeful, we believe these drugs are just temporary fixes. It’s essential to seek clinical support that improves mental health without unwanted side effects, whether through new medications or other means,” she stated.
“Weight loss injections should only be prescribed and used under professional guidance, with particular care taken for those at risk of eating disorders.”
