Understanding the Link Between Migraines and Gut Health: What You Need to Know
Introduction
Hi everyone, I'm Dr. Kevin Smith, a vestibular physical therapist. Today, I want to talk about something that might not be on your radar when it comes to migraines—the gut. If you're dealing with migraines or chronic migraines, you know how they can turn your life upside down. Work, relationships, just getting through the day—it all becomes a struggle. If you’re still trying to figure out what’s causing your vertigo, go ahead and download my free ebook on the five most common causes of vertigo and how to recover through the link below!

The Gut-Brain Connection
One crucial aspect to consider with migraines is the gut. There's some fascinating research out there that demonstrates an association between gut dysfunction and migraines. Our gut is full of bacteria and yeast that need to be in balance. When things get out of balance, or dysbiosis happens, it may lead to a host of issues, possibly including migraines.
The Gut-Brain Axis
The gut-brain axis is this two-way communication system between the gut and the brain. We all know how stress can give us butterflies in our stomachs—that’s a real thing. It’s not just in our heads; it’s a complex interaction of signals and substances between our gut and brain.
Research is showing that gut issues can lead to problems like anxiety and depression and possibly migraines. So, how exactly does the gut influence migraines?
The Vagus Nerve
A big player in the gut-brain connection is the vagus nerve. This nerve runs from the brain to the abdomen and significantly impacts the parasympathetic nervous system, which is all about that rest-and-digest state, helping us feel calm and relaxed. It also influences gut function. Keeping the vagus nerve healthy is crucial for maintaining good gut health.
Factors Influencing the Gut-Brain Axis
Several factors can mess with the gut-brain axis, including:
Inflammatory Mediators: Migraine sufferers often have elevated levels of pro-inflammatory cytokines, which can disrupt gut function.
Neuropeptides: Substances like CGRP and substance P are found at elevated levels in migraine patients and can influence gut health.
Serotonin Pathway: Serotonin is produced in both the brain and the gut and plays a role in pain and inflammation.
Stress Hormones: Stress can impact both brain function and gut motility.
Nutrients: Proper nutrition is vital for maintaining the gut barrier and its neuroprotective properties.
Gut Microbiome and Migraines
Studies have shown that the gut microbiome is different in people who suffer from migraines. Certain bacteria are found at higher levels in those with migraines compared to healthy folks. For example, researchers have identified increased levels of bacteria in migraine patients:
Tissierellia, Tissierellales, Peptoniphilaceae, Roseburia, Eubactgerium_g4, Agathobacter, PAC000195_g, Catenibacterium Haemophilus sp. Rothia sp. Clostridium species (e.g., Cl. asparagiforme, Cl. clostridioforme, Cl. bolteae, Cl. citroniae, Cl. hathewayi, Cl. ramosum, Cl. spiroforme, and Cl. symbiosum
Helicobacter pylori
One study found a higher prevalence of Helicobacter pylori infection in migraine patients (45%) compared to controls (33%). While this difference isn't huge, it’s statistically significant, suggesting a potential link between H. pylori infection and migraines.
IBS and Celiac Disease
Other gastrointestinal disorders like IBS and celiac disease have also been linked to migraines. Studies show that IBS is more common in migraine patients, and those with celiac disease are more likely to experience migraines.
Exploring the Cause-Effect Relationship
While we see these associations between gut dysfunction and migraines, the exact cause-effect relationship is still a bit murky. Researchers are trying to figure out if increased inflammation causes migraines or if migraines lead to increased inflammation. We definitely need more research to get to the bottom of this.
Practical Advice
If you’re dealing with migraines and suspect gut issues might be a factor, talk to your healthcare provider. They can help you address potential gut health problems that might be contributing to your migraines.
Conclusion
The connection between gut health and migraines is a developing area of research. Not everyone with migraines will have gut issues, but it's worth exploring if you’re struggling with chronic migraines. Lifestyle changes, like regular exercise, spending time in nature, and maintaining a balanced diet, can help improve gut health and might even help with your migraines. Not everyone experiencing migraines may have gut dysfunction, but there may be a subset of people with migraines that have an association with gut dysfunction.
Have you noticed any changes in your migraines after working on your gut health? I’d love to hear your experiences. Let’s keep the conversation going and support each other in finding effective ways to manage migraines!
