When people talk about menopause, the focus usually stays on hot flashes, mood swings, and sleep disturbances. Yet, there is one area that often gets overlooked, even though it affects how you feel every single day: your gut.
Can menopause affect gut health? The answer is yes, and for many women, it already has, even if they do not realise it yet.
Why Your Gut Starts Acting Up Midlife
Digestive health might not be the first thing that comes to mind when you think of menopause, but for many women, it quietly becomes one of the more disruptive changes.
Hormones have a much broader role in the body than most of us realise, and that includes how your digestive system behaves. As oestrogen and progesterone begin to decline, their influence on gut function also begins to change.
Oestrogen helps keep your digestive tract moving at a healthy pace, while progesterone has a relaxing effect on the muscles in your gut. When both of these start dropping, it can lead to slower digestion, more bloating and irregular bowel habits.
That is why the conversation about gut health and menopause should not just be about food. We also need to look at how hormonal change alters your entire internal environment.
Bloating, Bathroom Changes and What Is Really Going On
At Her Medical, some of the most common concerns we hear from women moving through the menopausal transition are discomfort after eating, unexpected bloating, and a bathroom routine that suddenly feels unpredictable.
These symptoms often stem from slower digestion, which allows food to linger in the gut. As it sits longer, gas builds and water is reabsorbed, leading to that tight, swollen feeling that can last for hours.
On top of that, lower progesterone levels affect the rhythm of your colon, causing constipation or alternating constipation and diarrhoea. Some women even find they react differently to foods they have eaten for years without any issue. All of these point to a gut that is out of rhythm with the rest of the body.
How Menopause Changes Your Gut Microbiome
After menopause, the collection of bacteria that helps regulate digestion, immunity and inflammation, called the gut microbiome, undergoes major shifts. Its diversity drops, and its composition begins to look more like that of men than premenopausal women.
Microbial diversity is important because it strengthens your body’s ability to process food, fight infection, reduce inflammation and even support mental clarity. A richer microbiome tends to mean more resilience, while a less varied one can leave the gut more vulnerable to imbalance and discomfort.
These changes in your gut microbiome affect more than just digestion. The balance between helpful and inflammatory bacteria shifts as well, often tipping toward microbes like Bilophila that can trigger gut irritation and inflammation. This can contribute not only to digestive issues but also to fatigue, weakened immunity and increased sensitivity to stress.
Your Body Stops Absorbing Nutrients Like It Used To
As the microbiome changes, it also affects how efficiently your body absorbs essential nutrients. After menopause, women are at higher risk for deficiencies in calcium, vitamin D, iron and omega-3s.
These nutrients support bone health, immune function and cognitive clarity. They also help regulate mood, maintain energy levels and support cardiovascular health. Unfortunately, lower microbial diversity and slower digestion can disrupt this process, meaning your body may need more support just to get the same benefit from food or supplements it once handled easily.
What Stress Does to Your Digestion During Menopause
Stress is another major player during menopause. The gut-brain axis—the two-way communication between your digestive system and your mind—can become even more reactive when hormones are shifting. Stress hormones like cortisol slow digestion further, make your gut more sensitive, and increase discomfort after eating.
Mood swings, anxiety and sleep disturbances all feed into this feedback loop and make digestive symptoms more intense. Many women do not realise their emotional stress is showing up in their gut, which can make symptoms feel confusing or unrelated.
Stress can also disrupt the microbiome, leading to an imbalance known as dysbiosis, which only adds to the cycle.
What Your Gut Says About Your Hormones
Your gut does not just react to hormonal changes. It also helps regulate them.
A specific part of the gut microbiome, called the estrobolome, produces enzymes that help recycle oestrogen in the body. When the estrobolome is functioning well, it helps maintain hormonal balance.
However, when the microbiome is disrupted, this process breaks down. Oestrogen may not be processed correctly, which can worsen symptoms like hot flashes, mood swings, and weight gain.
At the same time, digestive symptoms, such as bloating or irregular bowel movements, can become more pronounced, forming a frustrating cycle for many women.
Supporting Your Gut Through the Menopause Transition
The good news is that there are ways to support your gut through this transition. A diet rich in fibre, fermented foods, and plant-based variety can help restore microbial diversity.
Managing stress, getting enough sleep, and moving your body regularly also help calm the gut-brain axis.
At Her Medical, we work with women seeking support for the many changes they undergo before and after menopause. From digestive discomfort to hormonal shifts, every woman’s experience is different. That is why we offer individualised care, whether it involves nutrition support, hormone therapy, gut-focused treatments or lifestyle guidance.
