How Menopause Affects Gut Health – And What You Can Do About It

Menopause marks the natural end of a woman’s reproductive years. Typically occurring between the ages of 45 and 56, it’s defined as going 12 consecutive months without a menstrual period. Menopause is often accompanied by a range of physical and emotional changes, including hot flashes, sleep disturbances, and mood shifts. But what many people don’t realize is that menopause doesn’t just affect reproductive hormones — it also impacts gut health.

Emerging research shows that the decline in estrogen and progesterone levels during menopause can influence everything from how your digestive system functions to the balance of microbes living in your gut. These changes may help explain why many women experience symptoms like bloating, constipation, or other GI issues during midlife.

 In this blog post, we’ll explore how hormonal changes during menopause affect the gut, the most common digestive symptoms people face during this time, and evidence-based strategies to support gut health through menopause and beyond.

Understanding the Gut-Hormone Connection

Your gut is home to trillions of microorganisms, collectively known as the gut microbiome, that play a key role in digestion, immune function, and many other important bodily functions. This microbial community is also closely linked with your hormones, including estrogen and progesterone.

 Estrogen and progesterone help regulate gut motility (the movement of food through your digestive tract), influence the integrity of the gut barrier, and impact the composition of your gut microbiome. When these hormone levels decline during menopause, it can disrupt the balance of gut microbes and increase intestinal permeability (gut “leakiness”).

One key player in this connection is the estrobolome, a collection of gut bacteria involved in the metabolism and recycling of estrogen. This bidirectional relationship means that changes in gut health can impact hormones (and vice versa), making the gut-hormone connection particularly important during menopause.

How Menopause Affects Gut Health

Levels of estrogen and progesterone naturally decline during menopause, which can impact your gut health.

Menopause and the Gut Microbiome

Hormonal changes during menopause can shift the composition of the gut microbiome. Research shows that microbial diversity often decreases after menopause, which may increase gut permeability (colloquially known as “leaky gut”) and promote low-grade inflammation. This state of dysbiosis can not only worsen digestive symptoms but may also contribute to symptoms like fatigue and mood changes.

Increased Risk of GI Symptoms

Many women experience a range of digestive symptoms during menopause, including gas, bloating, indigestion, and unpredictable bowel habits. Some women may develop new or worsened irritable bowel syndrome (IBS) during this hormonal transition. However, more research is needed to fully understand why menopause is associated with digestive symptoms and increased rates of IBS.

Estrogen Metabolism and the Estrobolome

Estrobolome activity may be reduced during menopause, which can impair the body’s ability to recycle estrogen. This can contribute to symptoms like fatigue, brain fog, and mood swings, and may also influence breast cancer risk.

Gut Health and Menopause-Related Weight Gain

Weight gain (especially around the midsection) is a common complaint during menopause, and your gut health may play a role. The gut microbiome influences how your body digests food, regulates appetite, and stores fat. A balanced and diverse gut microbiome helps regulate hormones related to hunger and satiety, like ghrelin and leptin. But during menopause, microbial diversity often declines, which may lead to disruptions in these signals.

In addition, some animal studies suggest that changes in the gut microbiome affect the number of calories extracted from food. Hormonal shifts during menopause also promote the accumulation of visceral fat (fat stored around your internal organs), which is not only harder to lose but also promotes inflammation. Changes in the gut microbiome are also associated with the development of visceral fat, highlighting the important relationship between the gut microbiome and metabolic health.

Strategies to Support Gut Health During Menopause

Supporting gut health during menopause can help ease digestive discomfort, improve regularity, and promote overall well-being. Here are some evidence-based strategies to get you started.

Eat More Fiber

Fiber is essential for a healthy gut microbiome, and it helps increase microbial diversity while supporting regular bowel movements. Fiber also binds to excess estrogen in the gut, aiding in its removal from the body and hormonal balance.

 Aim to include a variety of fiber-rich foods like whole grains, flaxseeds, chia seeds, lentils, berries, and leafy greens. These foods not only nourish your gut microbiome, but can also help you feel full for longer and aid with weight management.

Include Fermented Foods

Fermented foods like yogurt, kefir, sauerkraut, kimchi, and tempeh contain beneficial bacteria and bioactive compounds that can help support gut health. Regularly incorporating them into your diet may help reduce bloating and improve digestion.

Manage Stress

Stress has a significant impact on the gut-brain axis and can exacerbate digestive symptoms. Managing stress through mindfulness meditation, deep breathing, or practices like yoga and tai chi can help regulate the gut-brain connection and may reduce gut discomfort.

Incorporate Physical Activity

Regular movement supports healthy digestion by promoting gut motility and facilitating the passage of gas and waste through the intestines. Exercise has also been linked to increased microbial diversity and reduced levels of inflammation.

Stay Hydrated

Adequate hydration is essential for preventing constipation and supporting smooth digestion. Aim for at least 8 cups of fluid daily (keep in mind that you may need more if you’re very active or live in a dry climate).

Final Thoughts

Menopause is a time of significant hormonal change, and those changes don’t just affect reproductive health. Shifts in estrogen and progesterone can impact gut motility, microbiome diversity, and inflammation, leading to digestive symptoms like bloating, constipation, and gas.

Fortunately, there are many simple, proactive ways to support your gut health during this phase of life. Prioritizing fiber-rich foods, including fermented foods, getting regular exercise, managing stress, and hydrating can all make a meaningful difference.
