What’s the Link Between Gut Health and Multiple Sclerosis?

Multiple sclerosis (MS) is a chronic condition that affects the central nervous system, disrupting communication between the brain and the rest of the body. While it’s often managed with medications and neurological care, a growing body of research suggests something unexpected may also play a role in its progression: gut health.

At IGEA Brain, Spine, Pain and Orthopedics, we stay on the leading edge of research to help patients manage complex neurological conditions like MS.

Understanding the Gut-Brain Axis

The gut and brain communicate constantly through a network known as the gut-brain axis. This connection links the gastrointestinal system with the central nervous system via neural, hormonal, and immune pathways. What happens in your gut—especially with your gut microbiome (the trillions of bacteria that live in your digestive tract)—can influence brain function, mood, inflammation, and even disease activity.

The Gut Microbiome and MS

Recent research has found that people with MS often have imbalances in their gut microbiome. These imbalances, or “dysbiosis,” may lead to increased inflammation and a disrupted immune response—both of which are central to the development and flare-ups of MS.

Some studies suggest that certain strains of gut bacteria may either exacerbate or help regulate the immune response in MS. For example:

• Harmful bacteria may trigger immune cells to mistakenly attack the protective coating of nerve fibers (myelin).
• Beneficial bacteria may help reduce inflammation and support immune tolerance, potentially calming MS activity.

Although the science is still developing, the link is strong enough that researchers are exploring gut-focused therapies—including probiotics, dietary changes, and even microbiome transplants—as potential ways to manage MS symptoms.

Can Improving Gut Health Help Manage MS?

While gut health alone won't replace medications or established MS treatments, it may support your overall wellness and reduce disease-related inflammation. Some strategies that may support a healthier microbiome include:

• Eating a fiber-rich, plant-based diet
• Reducing highly processed foods and added sugars
• Incorporating fermented foods like yogurt, kefir, kimchi, or sauerkraut
• Considering probiotic or prebiotic supplements under medical guidance

It’s important to talk with your care team before making major changes, especially when managing a condition as complex as MS.

Supporting the Whole Patient

At IGEA, we take a comprehensive, patient-centered approach to care. For patients living with MS, we focus not only on managing symptoms and preventing flare-ups but also on identifying ways to improve quality of life—including exploring the role of nutrition, inflammation, and gut health.

If you or a loved one is living with MS and looking for more than symptom control, we’re here to help guide you toward the most effective and holistic treatment options available.
