A study led by the University of Eastern Finland and the Karolinska Institutet in Sweden has found that GLP-1 medications, which are often used to treat diabetes and induce weight loss, may also improve mental health. The study followed nearly 100,000 individuals in Sweden between 2009 and 2022, including over 20,000 people who used GLPs. It found that those taking these medications were less likely to require hospital care or take extended leave due to psychiatric conditions. However, some experts have cautioned that the study does not prove that the medications directly improve the mental health of individuals.
