Could yoga have a therapeutic role in disorders of gut-brain interaction? Emerging evidence suggests that practices targeting stress, nervous system regulation and physical activity may support and enhance traditional dietetic care.

When patients with IBS, IBD or dyspepsia say their symptoms flare up during stress, they are describing the gut-brain connection in action. The gut-brain axis refers to two-way communication between the gastrointestinal tract and the central nervous system: an inner dialogue mediated through neural, hormonal, immune and microbial pathways.[1,2] This raises the question of whether yoga – through movement, breathing and relaxation practices – could help alleviate symptom flare-ups and influence processes such as motility, bowel regulation and overall gastrointestinal function.

How does yoga interact with the gut-brain connection?

Unlike dietary interventions, yoga influences gut function indirectly by regulating stress responses and supporting nervous system balance. Combining breath with movement, yoga shifts the body towards greater parasympathetic influence by stimulating the vagus nerve, enhancing vagal tone and strengthening the signalling pathways that link the gut and brain.[3] Yoga may also alter the hypothalamic-pituitary-adrenal (HPA) axis, reducing stress-related hormonal responses that are known to disrupt gut function.[2,3] Together, these help shape gut-brain signalling, offering an indirect approach to symptom management.

What does the evidence say about yoga’s role in gut-brain health?

Evidence exploring the effects of yoga and the gut-brain connection is growing, particularly in patients with IBS. A randomised clinical trial of an eight-week Hatha yoga programme found that participants engaged well with the program and noted how practical it was to implement, reporting improvements in IBS symptom severity, quality of life, fatigue and perceived stress.[4] This correlates with systematic reviews that suggest yoga may improve IBS symptoms, psychological well-being and overall quality of life.[5,6]

However, a note of caution: in the randomised trial, yoga was not statistically superior to the advice-only control group, indicating that improvements may not be attributable to yoga alone.[4] Generally, the evidence base consists of relatively small studies with limited participant numbers, short follow-up periods and variation in the style of yoga followed.[5, 6]

Combining approaches

At the core of the gut-brain axis lies the gut microbiome, steering stress responses, inflammation and neurotransmitter signalling.[1] Additional research combining yoga with probiotics similarly reported improvements in IBS-related quality of life and some microbiome markers, highlighting the potential of combining approaches to support gut-brain function.[7] However, evidence that yoga directly shapes the gut microbiome in a clinically meaningful way within gut-brain disorders remains limited. As diet and lifestyle factors also have a strong influence on microbial composition, yoga-related changes become difficult to disentangle.

Yoga for bowel health and regulation

Outside of clinical GI contexts, physical activity may offer a practical approach towards supporting gut-brain axis function for bowel health and regulation across broader populations, although the evidence base for yoga is still developing. Moderate exercise has been shown to enhance intestinal motility and reduce constipation risk,8 and yoga is likely to share comparable benefits through movement and mind-body mechanisms.

In particular, yoga influences physical factors relevant to bowel function, such as core engagement and pelvic floor strength, which are important in conditions such as chronic constipation and incontinence. However, this evidence is largely derived from postpartum populations.[9] This could be relevant for older adults, where constipation and pelvic floor dysfunction are common.

Engagement in yoga programmes among older adults is reportedly limited by perceived difficulty, fear of injury and access barriers, despite generally positive attitudes towards yoga.[10] Telehealth yoga may help overcome these barriers by improving accessibility and reducing travel, cost and anxiety associated with group settings.[11] However, guidance from a trained instructor remains important to support safe modifications and reduce injury risk.

What does this mean for dietitians?

Within a biopsychosocial approach, dietary advice remains central, but gastrointestinal symptoms are shaped within the wider gut-brain web. Stress, mood, sleep, physical activity and nervous system signalling all contribute to symptom experience, helping to explain why approaches beyond diet alone may support symptom management.

In practice, yoga could be put forward as a supportive self-management option, with potential benefits for gut-brain regulation and bowel function, particularly in populations where constipation and pelvic floor function are concerns. It may also help to regulate stress-related gut signalling and support quality of life in GI disorders. However, it should not be presented as a treatment or replacement for evidence-based dietary approaches. Patients should be encouraged to start gently and choose beginner-friendly classes led by qualified and trained instructors, with yoga positioned as a supportive addition alongside dietary care.

Conclusion

Framed within the context of the gut-brain network, yoga shows clinical promise. For dietitians and patients, yoga is not primary care but could be a low-risk assist that supports gut-brain balance. The evidence points towards benefit, but stronger and longer-term studies are needed before firm clinical recommendations can be made.
