A major new study from King's College London suggests that medications used to treat diabetes and obesity may also help improve emotional health.

These drugs, known as GLP-1 receptor agonists (or GLP1-RAs), include medications like semaglutide, which are already widely used to support weight loss and manage blood sugar levels. The study provides new evidence that they are not only physically safe but may also benefit mental health.

People living with obesity or diabetes often face emotional struggles such as depression, low self-esteem, and poor mental health. These issues can make it harder for them to take their medications properly or stick to a healthy routine.

In some cases, this can lead to poor blood sugar control and more health problems. There have been some concerns in recent years that GLP1-RAs could make mental health worse, but those reports have been unclear and not always based on strong evidence.

To get a clearer picture, researchers at the Institute of Psychiatry, Psychology & Neuroscience (IoPPN) at King's College London carried out a meta-analysis -- a type of study that combines results from many earlier studies to find larger patterns.

They looked at 80 high-quality clinical trials involving over 107,000 people with obesity or diabetes. These trials compared people taking GLP1-RAs to those taking a placebo (a dummy treatment) to see if there were any differences in mental health outcomes.

The results were encouraging. The researchers found no increased risk of psychiatric side effects, such as depression or anxiety, in people using GLP1-RAs compared to those using a placebo. This means that taking these medications does not seem to make mental health worse.

In fact, the study found some positive effects. People taking GLP1-RAs reported better mental health-related quality of life. That means they felt better emotionally and mentally in their day-to-day lives.

The study also found that these drugs helped reduce emotional eating and encouraged more mindful or restrained eating habits. Emotional eating is when people eat to deal with stress, sadness, or boredom, which can make weight problems harder to manage.

Dr. Toby Pillinger, one of the lead researchers from King's, explained that living with obesity or diabetes can seriously affect both physical and emotional health.

He said this large study helps show that GLP1-RA medications not only support weight and blood sugar control but may also help people feel better emotionally. This is important as these drugs are being prescribed more and more around the world.

In summary, this study brings good news for both patients and doctors. It confirms that GLP1-RA drugs like semaglutide are not linked to harmful mental health side effects.

Even better, they may actually improve how people feel emotionally, particularly by reducing emotional eating and helping them feel more in control of their food choices. As these medications continue to play a big role in treating obesity and diabetes, this added mental health benefit could make them even more valuable.
