Because "eat more fibre" may be missing the actual point.
If your gut feels slower than it used to, you're not imagining it. Many women in their late thirties and forties notice changes in their digestion: more bloating, more constipation, or a general sense that things just aren't moving the way they once did. A study published this week suggests that gut transit time, how long food takes to travel through your system, may be more than a comfort issue. It could be a meaningful signal worth paying attention to on your gut wellness journey.
What Is Gut Transit Time, and Why Might It Matter?
Gut transit time refers to how long it takes for food to travel from your mouth to, well, the other end. Research suggests this may vary enormously between people, ranging from as little as 10 hours to more than 73 hours. For most people, a transit time somewhere between 24 and 48 hours appears to fall within a healthy range, though researchers are careful to note that "normal" is still being defined and may vary considerably between individuals.
What the emerging science appears to show is that transit time may be linked to the diversity and composition of your gut microbiome. A slower transit time appears to be associated with lower microbial diversity, which researchers think may, in turn, be linked to everything from nutrient absorption to immune function. A faster transit time appears to carry its own considerations too, including the possibility that nutrients may pass through before being properly absorbed. Neither extreme appears to be where you want to be, though individual responses seem to vary considerably.
Why Your Gut May Feel Different in Your Thirties and Forties
The connection between hormonal changes and gut motility, how actively your gut moves things along, is an area of growing research interest. Estrogen and progesterone appear to influence how quickly the gut contracts and moves food through your system, which may partly explain why so many women notice digestive changes during perimenopause.
Studies indicate that as estrogen levels begin to fluctuate in the years before menopause, the gut microbiome also appears to shift. Researchers believe this may affect the production of short-chain fatty acids, compounds that seem to play a role in supporting the gut lining and gut motility. In other words, the hormonal changes of perimenopause may affect your gut in ways that go well beyond the occasional bout of bloating. For many women, this connection appears to be real and worth exploring.
What You Can Do With This Information
The most useful thing you can do is start noticing. Not obsessively, but with genuine curiosity.
- How does your gut appear to respond after different meals?
- Do certain foods seem to slow things down?
- Does stress appear to affect your gut's pace?
- Does your digestion feel different at different points in your cycle?
Research suggests that some dietary approaches may support gut motility. Adequate fibre intake, particularly from a variety of plant sources, appears to be associated with greater microbiome diversity, which may in turn support more comfortable transit times. Staying well hydrated may help too, and regular movement appears to play a role. Some studies suggest that even gentle walking after meals may be associated with gut motility support, which seems like a relatively low-effort thing worth exploring.
A gut wellness monitor like Gutsi may help you track patterns over time, so that instead of guessing what your gut might be responding to, you have something more concrete to explore on your gut wellness journey.
