Recent research has revealed that drugs like Ozempic and Wegovy, originally approved to treat diabetes and aid in weight loss, may offer a range of additional health benefits. However, these medications, which belong to the class of GLP-1 agonists, also present new risks that need careful consideration, particularly regarding their long-term effects.
GLP-1 agonists mimic a natural hormone that helps regulate appetite and slow digestion, and they have become popular in recent years for their weight-loss benefits. A new study, involving 200,000 participants in the U.S., suggests that these medications may also lower the risk of conditions such as Alzheimer’s disease, adding to their list of potential benefits.
Despite the promising findings, experts urge caution. Dr. Abraham Snaiderman, a psychiatrist with the Toronto Rehabilitation Institute, emphasized that while the study is compelling, it should not lead people to start using these drugs for conditions beyond diabetes and obesity. Dr. Ziyad Al-Aly, the senior author of the study, explained that those already using these drugs for weight loss may notice additional benefits, such as reduced cravings and a potential decrease in addiction behaviors.
The study, published in Nature Medicine, explored the relationship between GLP-1 drugs and 175 health conditions over 3½ years in people with diabetes. It found that these medications may help reduce the risk of heart disease, stroke, kidney disease, and even mental health conditions such as schizophrenia and suicidal ideation. One of the more unexpected findings was that GLP-1 drugs were linked to a lower risk of addiction disorders, as they act not only on the stomach but also on brain areas involved in impulse control and reward-signaling.
However, the study also highlighted some significant health risks. Side effects like nausea, vomiting, arthritis, and low blood pressure that can cause fainting were reported. Additionally, the medications were linked to an increased risk of pancreatitis, a potentially life-threatening inflammation of the pancreas. There is also concern that these drugs could cause kidney inflammation, possibly due to dehydration from decreased water intake.
Dr. Al-Aly suggested that the increased joint pain seen with these drugs might be more complex, as weight loss typically improves arthritis. The drugs’ widespread effects on various organs, including the brain, could explain the diverse range of benefits and risks they present. Dr. Donald Weaver, senior scientist at the Krembil Research Institute, noted that the link between Type 2 diabetes and Alzheimer’s disease makes the use of GLP-1s for neurological disorders an area of growing interest.
Despite the potential for these drugs to offer broad health benefits, the researchers caution against their use for non-approved purposes until more rigorous clinical trials are conducted to confirm these associations. The drugs are expensive, and their side effects may not make them suitable for everyone.
Dr. Daniel Drucker, a clinician-scientist who helped develop these medications, called the study a powerful analysis but echoed the importance of waiting for more data. Furthermore, the study sample, primarily made up of older, white men, highlights the need for future research to include a more diverse group of participants to better understand the broader impact of these medications.
In conclusion, while drugs like Ozempic show promise in combating a variety of conditions, including dementia, they are not without risks. As with any new treatment, patients should consult their doctors and wait for further evidence before using these medications beyond their intended purposes.
