Let’s dive into what the researchers learned about these gastrointestinal symptoms—and what might help mitigate them. The results showed that women are statistically more likely to experience nausea/vomiting, abdominal pain, diarrhea, constipation, loss of appetite, heartburn, weight gain, and bloating during premenopausal, perimenopausal, and postmenopausal states. Interestingly, the only GI symptom that wasn’t more prevalent and more severe during these states was weight loss. Some of the study’s most striking observations were racial and ethnic associations. For example, Asian participants reported a lower number and lower total severity of GI symptoms, while non-Hispanic white participants had higher total severity scores than other groups, especially for nausea/vomiting, diarrhea, constipation, and loss of appetite. Meanwhile, Hispanic participants were more likely to have higher severity scores for constipation, weight gain, and bloating. As it turns out, there’s a well-known link between estrogen and digestion. For example, a review of 18 studies2 found a clear link between times of declining or low ovarian hormones and an increase in GI symptoms, suggesting that estrogen (and progesterone, the other main female sex hormone) withdrawal may contribute either directly or indirectly to GI distress. If you’ve ever found yourself running to the bathroom before or during your period, you’ve already experienced this connection in action. There’s still quite a bit of mystery surrounding the ins and outs of the relationship between hormonal health and gut health, but previous research has shown that there’s a lot of interplay between sex hormones and the microbiome. The authors of one study3 explain that sex hormones influence the gut microbiota due to their involvement in microbial metabolism, and in turn, the gut microbiota influence sex hormone levels. According to the North American Menopause Society, levels of cortisol (often referred to as the main “stress” hormone) also increase during menopause. This can initiate an increase in adrenaline, which can lead to changes in digestive function. As this organization explains it: “For example, gas could build up with bloating. Foods could go through the GI tract without being fully broken down, resulting in constipation.” For many of us, this is pretty relatable. It’s common to end up with a stomachache, bloat, or heartburn during stressful periods in our lives. You’ve probably heard about probiotics before. These “friendly” bacteria are found naturally in fermented foods (think kimchi, yogurt, and kefir) and can be a powerful tool for promoting overall health. A well-formulated probiotic supplement can also ease digestive distress and holistically support your gut microbiome throughout all stages of your life, regardless of your age or gender. In fact, it has also been shown that poor gut health can affect testosterone production4 in men, so investing in a healthy microbiome really behooves us all. To get you started, here’s a list of our favorite probiotic supplements.
