Discovering the Connection: Gut Microbiota’s Role in Migraine and IBS
Recent research unveils a fascinating connection between two seemingly unrelated conditions: migraine and Irritable Bowel Syndrome (IBS), particularly in the Chinese Han population.
This study highlights the critical role of gut microbiota in these conditions, revealing insights that could transform our approach to healthcare.
The Study: A Comprehensive Look at the Chinese Han Population
Conducted at the International Headache Center of Chinese PLA General Hospital, the research focused on 29 Chinese Han individuals, including 16 migraine patients with IBS and 13 IBS patients without migraine.
The participants, aged between 23 and 58 years, were carefully chosen to ensure no significant differences in factors like age, BMI, education, or lifestyle habits, ensuring the study’s accuracy (χ2 and t-values).
Uncovering the Mystery: Clinical Characteristics and Microbial Analysis
Intriguingly, the study found that while there were no significant differences in most lifestyle factors between the two groups, the migraine patients with IBS showed higher anxiety levels (HAMA scores) than the IBS group without migraine (P = 0.006).
This suggests a potential link between psychological factors and the gut-brain axis in these conditions.
Gut Microbiota: The Crucial Link
Using advanced 16S rRNA sequencing, the researchers analyzed the gut microbiota’s alpha and beta diversity.
They found significant differences in the gut microbial structure between migraine patients with IBS and those with only IBS (P = 0.041 for Bray–Curtis PCoA; P < 0.001 for PLS-DA).
This indicates a distinct microbial pattern in individuals suffering from both conditions.
Taxa Alteration: A Key Discovery
At the phylum and genus levels, differences in the abundance of certain microbiota like Bacteroidota and Firmicutes were noted, though not statistically significant.
However, the presence of Cyanobacteria was exclusive to the IBS group, suggesting a unique microbial signature in migraine patients with IBS.
Predictive Models: Towards Personalized Medicine
Using Random Forest predictive models, the study identified specific microbiota and clinical data, like the Hamilton Anxiety and Depression scores, that could predict the presence of migraine in IBS patients.
This highlights the potential of personalized medicine in treating these conditions.
No Direct Correlation, But a Trend Towards Significance
While the study didn’t find a direct statistical correlation between gut microbiota and clinical characteristics of migraine, there was a trend toward significance.
For instance, the genus Parabacteroides showed a potential positive correlation with sleep quality (PSQI scores), and Paraprevotella showed a negative trend with disease duration (DD).
Gut Microbiota Connection in Migraine and IBS
Migraine and IBS: A Complex Connection
Migraine and IBS often coexist, leading to a more challenging prognosis for those affected.
However, identifying specific biomarkers for migraine within the context of IBS has proven elusive.
This study represents a pioneering effort, revealing noteworthy alterations in gut microbiota among migraine patients with IBS.
Surprisingly, these changes didn’t correlate with clinical migraine characteristics 18.
Understanding Microbial Diversity
While the study didn’t find significant differences in the diversity of gut microbiota in migraine patients with IBS compared to those with IBS alone, it did uncover distinct qualitative differences in their microbiota profiles.
A parallel study involving elderly women with migraines further emphasized the importance of microbial diversity.
This study revealed a notable decrease in alpha diversity, indicating a less varied microbiota in migraine sufferers at both the genus and species levels.
However, species richness remained consistent between the migraine and control groups 19.
The differences in alpha diversity results between the two studies could be attributed to several factors.
Firstly, the study populations differed; the current study focused on migraine patients with IBS and IBS patients, while the other study centered on elderly female migraine patients and healthy individuals.
Secondly, distinct stool detection methods were employed—16S rRNA gene sequencing in the current study and metagenomic shotgun sequencing in the previous research.
Lastly, diversity analysis was based on different data, with the current study using OTUs and the previous one focusing on genus and species levels.

Phylum-Level Insights
At the phylum level, the study uncovered intriguing findings.
Migraine patients with IBS exhibited a higher abundance of the gram-negative phylum Bacteroidota and lower levels of the gram-positive phyla Firmicutes and Actinobacteriota, although these differences didn’t reach statistical significance.
Notably, predictive models highlighted the importance of the Bacteroidota phylum in migraine patients with IBS 20.
These findings resonate with research in central nervous system diseases, such as Alzheimer’s disease21, Parkinson’s disease22,
multiple sclerosis, major depressive disorder23 , and autism spectrum disorder24, which also observed decreased Firmicutes and increased Bacteroidetes in the gut microbiota.
However, variations were noted compared to other studies.
For instance, individuals with obesity tend to have a higher F/B ratio, more Firmicutes, and fewer Bacteroidetes 25.
Conversely, patients with IBS typically show increased Firmicutes and decreased Bacteroidetes 26.
Additionally, a study on elderly female migraine patients found significantly higher levels of Firmicutes relative to controls27 .
This divergence at the phylum level suggests that changes in gut microbiota may indeed be associated with the occurrence of migraine within the context of IBS.
The balance between Firmicutes and Bacteroidetes, along with the potential for immunoregulatory and proinflammatory responses, could play a pivotal role in the pathogenesis of migraine in IBS patients.
Furthermore, the absence of the phylum Cyanobacteria in migraine patients with IBS raises intriguing questions about its potential role in this condition 28.
Genus-Level Insights
Exploring the gut microbiota at the genus level uncovers additional layers of complexity.
Notably, migraine patients with IBS exhibited a higher relative abundance of Parabacteroides and lower levels of Paraprevotella, Lachnospiraceae_UCG-010, Lactococcus, Collinsella, and Comamonas.
These findings were corroborated by LEfSe analysis, which revealed an overrepresentation of Parabacteroides and a dearth of Paraprevotella in the gut microbiota of migraine patients with IBS.
Parabacteroides, a group of gram-negative anaerobic bacteria within the Bacteroidota phylum, is known for its proinflammatory effects through substances like LPS and succinic acid 29.
Paraprevotella, also within the Bacteroidota phylum, contributes to the production of propionate and exerts anti-inflammatory effects 30.
Lachnospiraceae_UCG-010, though less understood, may have a beneficial role31.
Lactococcus, a genus of gram-positive bacteria, is crucial for intestinal health and the synthesis of antimicrobial compounds 32.
Reduced levels of Lactococcus in migraine patients with IBS could potentially affect sex hormone levels 33.
Comamonas, a genus in the Proteobacteria phylum, plays a role in vitamin B12 synthesis 34.
Contrary to these findings, a metagenomic study on elderly women with migraines identified detrimental species, especially Clostridium spp., as significantly enriched in migraineurs.
In contrast, the controls had more beneficial microorganisms like Bifidobacterium adolescentis, Faecalibacterium prausnitzii, and Bacteroides intestinalis, along with some less friendly species 35.
Overall, these varied results highlight the complexity of the gut microbiota’s role in migraine and IBS, which may be influenced by factors such as sex hormone changes, inflammation, and vitamin B12 levels.
No Correlation with Clinical Characteristics
Intriguingly, the study found no correlation between the gut microbiota genus and clinical characteristics of migraine.
This included variables such as attack frequency, disease duration, pain severity, migraine disability, sleep quality, anxiety, and depression.
Nevertheless, a potential positive correlation trend was observed between the genus Parabacteroides and PSQI scores, suggesting that increased Parabacteroides may be associated with poorer sleep quality, likely due to its pro-inflammatory nature.
On the other hand, a potential negative correlation trend was identified between the genus Paraprevotella and disease duration, implying that longer migraine duration may reduce the abundance of Paraprevotella, weakening its anti-inflammatory effects
Future Directions
This groundbreaking study opens new avenues for understanding and potentially treating migraine patients with IBS
However, it remains unclear whether the observed alterations in gut microbiota are causative or consequential.
Animal experiments will be essential in verifying these findings and elucidating the underlying mechanisms.
Limitations must be acknowledged.
The study’s sample size was limited, necessitating further research with larger and more diverse populations.
Cohort studies could provide valuable insights into disease progression.
To gain deeper insights, future studies should consider employing shotgun metagenome analysis for functional and species-level analysis.
