The Fibromyalgia-Gut Connection: Why Your Digestion Matters

Practical Strategies for Gut Health

Understanding the gut-fibromyalgia connection is empowering because gut health is something you can actively influence. Unlike many fibromyalgia triggers, you have substantial control over what you eat and how you support your gut microbiome.

Probiotics That Actually Help

Not all probiotics are equal. Research specific to fibromyalgia has identified certain strains that appear beneficial. Look for products containing Lactobacillus and Bifidobacterium species, particularly Lactobacillus plantarum and Bifidobacterium longum, which have shown promise in fibromyalgia studies.

Start with a modest dose and increase gradually. Probiotics can cause temporary bloating and gas as your gut adjusts. Quality matters—choose products from reputable manufacturers with third-party testing. Refrigerated probiotics typically contain higher numbers of live organisms.

Prebiotics—fiber that feeds beneficial bacteria—are equally important. Foods like garlic, onions, asparagus, bananas, and oats provide prebiotic fiber that helps beneficial bacteria thrive.

The Low-FODMAP Approach

Many fibromyalgia patients with IBS symptoms benefit from a low-FODMAP diet. FODMAPs are fermentable carbohydrates that can trigger digestive symptoms in sensitive people. The diet involves temporarily eliminating high-FODMAP foods, then systematically reintroducing them to identify personal triggers.

This isn't a permanent elimination diet—it's a diagnostic tool to identify which specific foods cause your symptoms. Most people can eventually reintroduce many foods and only need to avoid their specific triggers. Working with a dietitian experienced in FODMAP protocols increases success rates.

Anti-Inflammatory Eating

Focus on foods that reduce rather than promote inflammation. This generally means emphasizing whole, unprocessed foods: vegetables, fruits, lean proteins, healthy fats (olive oil, avocados, fatty fish), and minimizing processed foods, refined sugars, and trans fats.

The Mediterranean diet pattern has research support for reducing inflammation and improving symptoms in fibromyalgia. It's not restrictive or extreme—it's sustainable, evidence-based eating that supports both gut health and overall fibromyalgia management.

Testing for SIBO

If you have significant bloating, especially worsening throughout the day, ask your doctor about SIBO testing. The breath test for SIBO is non-invasive and can identify if bacterial overgrowth is contributing to your symptoms. Treatment typically involves antibiotics or herbal antimicrobials followed by probiotics and dietary changes.
