As multiple sclerosis (MS) continues to challenge those living with the condition, recent studies have raised the possibility that weight loss drugs, particularly GLP-1 medications like Ozempic and Wegovy, may offer benefits beyond traditional treatments. These medications, typically used for managing obesity and type 2 diabetes, have garnered attention for their potential to improve MS symptoms, though researchers caution that further investigation is required to fully understand their effects.
Obesity’s Impact on Multiple Sclerosis
Obesity has long been linked to worsened MS outcomes, with extra weight exacerbating symptoms and increasing disease severity. According to Dr. Afsaneh Shirani, a neurologist at the University of Nebraska Medical Center, excess body fat triggers chronic, low-level inflammation, which can intensify the inflammation in the brain and spinal cord, thereby worsening MS symptoms. Additionally, obesity can disturb the immune system, elevating harmful pro-inflammatory cells while decreasing protective ones. This imbalance may contribute to more frequent relapses and faster disease progression in people with MS.
Obesity is also frequently associated with comorbidities such as hypertension, diabetes, and cardiovascular disease, which can further compromise neurological health and aggravate common MS symptoms like fatigue and mobility issues.
The Role of Nutrition and Weight Management
Maintaining a healthy weight is crucial for individuals with MS, not only to reduce the risks of other health complications but also to manage disease progression. Dr. Anne H. Cross, a neurologist at Washington University, notes that the benefits of a healthy weight and balanced diet for MS patients are similar to those seen in the general population: a lower risk of heart disease, diabetes, and other chronic conditions. Healthy weight management helps preserve mobility, delays physical disability, and boosts energy levels, potentially easing the fatigue that many MS patients experience.
While traditional approaches such as regular exercise and a balanced diet remain vital in weight management, recent trends have seen calorie restriction—especially intermittent fasting—gaining traction as a potential tool for MS patients. Dr. Cross highlights that some small studies suggest calorie restriction may not only help with weight loss but could also support nerve repair processes in MS patients.
Weight Loss Medications and MS: Early Findings
A 2024 study led by Dr. Shirani, Dr. Cross, and Dr. Olaf Stuve from the University of Texas explored the relationship between weight-loss medications and MS using data from the U.S. Food and Drug Administration’s Adverse Event Reporting System. The study investigated whether certain weight-loss drugs, such as GLP-1 medications, were linked to a reduction in MS reports. While the study did not prove a direct protective effect, the findings suggested that some antidiabetic medications promoting weight loss might hold promise as potential treatments for MS.
However, as Dr. Shirani points out, the findings do not establish a definitive cause-and-effect relationship, and much more research is necessary before these medications can be repurposed for MS treatment. Clinical trials specifically focused on MS are needed to confirm these preliminary results.
Caution Regarding GLP-1 Medications
Both Dr. Cross and Dr. Shirani urge caution when considering GLP-1 medications for MS management. “We are not recommending that patients use these drugs specifically for MS until scientific data from clinical trials are available,” Dr. Cross states. Although weight management remains a critical aspect of MS care, these medications should only be used for their approved purposes, such as managing obesity or type 2 diabetes, until more conclusive evidence emerges regarding their efficacy in treating MS itself.
The Future of MS Treatment: Metformin and Other Investigations
Looking ahead, researchers are also exploring other potential treatments that may benefit MS patients. Dr. Cross is closely following studies on metformin, a drug commonly used to treat type 2 diabetes. Several global studies are investigating whether metformin could have a positive impact on MS, particularly in promoting nerve repair and reducing inflammation. One such study, led by Dr. Barbara Willekens at Antwerp University Hospital in Belgium, is testing the effectiveness of metformin in people with progressive MS. Early animal studies have shown promising results, indicating that metformin may protect nerves and promote myelin repair.
If successful, metformin could become a safe, accessible treatment to slow disease progression and restore function in people with progressive MS.
A Holistic Approach to MS Care
For those living with MS, maintaining overall health through regular exercise, a balanced diet, and adequate hydration remains essential. Dr. Shirani recommends focusing on whole foods, such as fruits, vegetables, lean proteins, and healthy fats, and following anti-inflammatory diets like the Mediterranean or plant-based diets. Regular low-impact exercises such as walking, swimming, or yoga can help improve mobility and cardiovascular health, while stretching and strength training can reduce fatigue.
Collaboration with healthcare providers, including neurologists, dietitians, and physical therapists, is crucial to create a personalized plan that takes into account MS symptoms and any comorbidities. As always, it’s important for patients to consult their doctors before making significant changes to their treatment plans.
In summary, while weight loss medications like GLP-1 drugs hold promise for improving MS outcomes, much more research is needed before these treatments can be recommended as part of standard MS care. Until then, a balanced diet, regular exercise, and professional medical guidance remain the cornerstones of effective MS management.
