For Kathy Schwartz, the battle against cravings for alcohol, cigarettes, and opiates was a daily struggle, despite being ten years free from these substances. However, in June last year, a turning point occurred.
Prescribed the weight-loss drug semaglutide, Schwartz not only shed nearly 30 kilograms over 10 months but also experienced a significant reduction in her cravings. “I do not crave, which I didn’t think would be a side effect,” she shares. Remarkably, her previous struggles with depression and anxiety also lessened.
Schwartz’s experience is not isolated. Recent research is uncovering the unexpected brain and mental health benefits of semaglutide drugs like Ozempic and Wegovy, along with other related diabetes and weight-loss medications that mimic a gut hormone released after eating.
While it’s still early in the research, there are indications that these drugs could be repurposed to address conditions such as depression, anxiety, addiction, and certain eating disorders. Additionally, they might have potential applications in neurological conditions like Parkinson’s disease and Alzheimer’s. Intriguingly, these effects appear to be mediated not only through weight loss but also through direct action on the brain.
The story of drugs like Ozempic traces back to the 1970s and 1980s when researchers discovered that a gut hormone called glucagon-like peptide-1 (GLP-1) could stimulate insulin production and lead to weight loss when injected into laboratory rodents. Further research revealed that GLP-1 increases the feeling of fullness.
Today, drugs like semaglutide are at the forefront of this research, offering promising avenues for addressing mental health and brain-related conditions beyond their original purpose of weight loss. As the scientific community delves deeper into understanding the mechanisms behind these effects, the potential for transformative treatments in various health domains continues to grow.
