Yes, in many women. Changes in gut motility, the microbiome and bowel habits can all contribute. Stress, diet and food intolerances play a role too. Persistent or new-onset bloating always warrants a proper clinical assessment rather than the assumption that it is purely hormonal.
Gut health and menopause:
How Changing Hormones Affect Your Digestion And Microbiome
Ms Monica Durigon
09, October 2026
Bloating, constipation, changes in bowel habits or a feeling that digestion is simply different are among the more common, and more overlooked, experiences of perimenopause and menopause. For some women these symptoms appear for the first time. For others, existing digestive issues become more noticeable as hormones change.
LIPS Healthcare provides gastroenterology, nutrition and menopause care at Battersea Power Station, London, with specialist clinicians who understand the connection between hormonal health and gut function. This article explains how gut health and menopause interact, what the evidence shows and which changes make the most practical difference.
TABLE OF CONTENTS:
What happens to your digestion during menopause?
During menopause, declining oestrogen levels can affect gut motility, bowel habits and the composition of the gut microbiome. Common changes include bloating, constipation, acid reflux and altered food tolerance. These occur because the gastrointestinal tract contains receptors for sex hormones.
A major 2025 review in Nature Reviews Gastroenterology and Hepatology concluded that menopause can affect gastrointestinal health through changes in gut motility and microbial composition. Some gastrointestinal conditions may also become more symptomatic during peri- and postmenopause.
Common digestive changes include:
- Bloating, particularly after meals or in the afternoon
- Constipation or noticeably altered bowel habits
- Acid reflux or indigestion that has changed in pattern
- Abdominal discomfort
- Changes in food tolerance, including foods previously well tolerated
Persistent or significant gastrointestinal symptoms always warrant proper clinical assessment. Other causes need to be ruled out, not assumed away. But hormonal changes are a legitimate and often underrecognised part of the picture.
How menopause changes the gut microbiome
The gut microbiome is the community of bacteria and other microorganisms living within the intestinal tract. These organisms break down food components, produce useful metabolites, communicate with the immune system and support the intestinal environment.
Studies comparing premenopausal and postmenopausal women have found differences in microbial diversity and composition. One of the largest human studies found that the microbiome of postmenopausal women became somewhat more similar to that seen in men, and that some of those microbial differences were associated with less favourable cardiometabolic markers.
More recent reviews support the idea that declining oestrogen influences microbial composition, but they also emphasise that there is no single healthy menopausal microbiome. Diet, geography, medications, activity levels and many other factors shape the microbiome. Individual variation is substantial, which is why a personalised approach always outperforms a generic one.
What is the estrobolome and why does it matter?
The estrobolome refers to the collection of gut microbial genes capable of influencing how oestrogens are metabolised in the body.
After oestrogen is processed by the liver, some is released into the intestine ready for elimination. Certain gut bacteria produce enzymes that can convert some of these oestrogens back into a reabsorbable form, allowing them to re-enter the circulation. The microbiome may therefore influence how much active oestrogen remains in the body.
This mechanism is genuinely interesting and helps explain some of the interaction between gut health, menopause and hormonal balance. However, it remains an evolving area of science. We cannot currently read a microbiome test result and reliably identify which bacterial pattern is responsible for a particular woman's symptoms, or prescribe a specific microbial combination to adjust oestrogen levels. The estrobolome is important ongoing research, not yet a stand-alone clinical tool.
What to eat for better gut health during menopause
The most evidence-based starting point for supporting the gut microbiome is not a supplement. It is the quality and diversity of food eaten consistently over time.
Gut bacteria use plant-based fibres and polyphenols as fuel. Increasing plant variety is one of the most practical and well-supported strategies available. Useful foods include:
- A wide range of vegetables, aiming for variety rather than volume
- Fruit and berries
- Beans and lentils
- Whole grains: oats, quinoa, brown rice
- Nuts and seeds
- Herbs and spices, which contribute polyphenols and diversity
Fermentation of certain fibres by gut bacteria produces short-chain fatty acids, which support the cells lining the colon and play a role in immune and metabolic signalling.
More fibre is not automatically better for every woman. Those already experiencing significant bloating, constipation or IBS-type symptoms may find a sudden increase makes things worse before they improve. The type, amount and pace of introduction all matter. Adequate hydration and regular physical activity are equally important, as fibre works best alongside both.
Are probiotics worth taking during menopause?
Fermented foods such as natural yoghurt, kefir, kimchi, sauerkraut and traditionally fermented vegetables can contribute microbial diversity and are a useful addition for most women, provided they are well tolerated.
Specific probiotic supplements are a more complicated question. A 2025 review found encouraging evidence that some prebiotic and probiotic interventions may influence microbial diversity and aspects of metabolic health during menopause. A 2025 systematic review and meta-analysis also examined probiotic use across the menopausal transition, reflecting growing research interest in this area.
Both sets of researchers were clear: the evidence base is still developing and we do not yet know which strains, doses or combinations are most beneficial for which women. Probiotic effects tend to be strain-specific. A product labelled "for menopause" is not automatically appropriate for a given individual.
The most suitable option, if one is clinically indicated, depends on the individual's digestive history, symptoms, current diet and overall health picture. A clinician can advise based on that full picture rather than a label.

Frequently asked questions about gut health and menopause
Emerging research suggests that the gut microbiome and oestrogen metabolism interact through the estrobolome. However, we do not yet have sufficient clinical evidence to reliably alter menopause symptoms by targeting specific microbial patterns. Diet, fibre intake and fermented foods are the most evidence-based starting points.
Early evidence is encouraging but not yet conclusive. Probiotic effects are strain-specific, so choosing based on a label is unreliable. Fermented foods are a safer and better-evidenced daily habit. For specific probiotic supplementation, speak to a clinician who can advise based on your individual history.
A diverse range of plant foods, adequate fluid intake and fermented foods where tolerated provide the most consistent dietary support. Oats, beans, lentils, vegetables, whole fruit and nuts all contribute fibre and support the microbiome. Introducing variety gradually tends to work better than sudden large increases in fibre.
See a clinician promptly if you notice persistent changes in bowel habits, unexplained weight loss, blood in the stool, significant abdominal pain or symptoms that interfere with daily life. Do not assume all new digestive symptoms are hormonal. Specialist gastroenterology assessments, including same-day consultations, are available at LIPS Healthcare, Battersea Power Station.
It can be useful in specific clinical contexts when interpreted alongside symptoms, dietary intake, bowel habits, medical history and relevant investigations. A test result on its own is not a diagnosis. The value depends on whether the findings change the clinical approach. Discuss with a clinician whether it would genuinely add to your management plan.
