The Estrogen–Inflammation Connection in Perimenopause & Menopause

In 2020, well into the midst of Covid, I was slowly becoming someone I didn’t recognize. I was gaining weight, struggling with brain fog, and at times thought that I may just have ADD because the ability to concentrate continually eluded me. My sleep was also suffering and, completely out of the blue, I was diagnosed with rosacea. I thought it was all due to working from home and not getting enough movement due to the lockdown. I slowly came to realize that all my symptoms came down to perimenopause.

When I realized what may be going on, I reached out to my doctor. I was told that, yes, I was probably in perimenopause but there was really not much I could do about it. “Eat better and get exercise” was what I was told. Of course, she never asked me one question about what I was already doing, which was eating well and exercising. But that is a story for another post.

If you’ve been told that your symptoms are “just part of aging,” you’re not wrong but your practitioner is not providing a full picture either.

One of the most important, and often overlooked, pieces of this transition is the relationship between estrogen and inflammation.

Estrogen isn’t just a reproductive hormone. It plays a powerful role in regulating the immune system and keeping inflammation in check. In many ways, it acts as a natural anti-inflammatory in the body, helping to protect everything from your brain to your heart to your bones.

During perimenopause, estrogen doesn’t simply decline in a straight line. It zig zags on its way down. These swings can feel unpredictable as your body tries to adapt. This is often when women begin noticing symptoms like mood changes, disrupted sleep, and increased sensitivity to stress.

Then in menopause, estrogen levels drop more steadily and remain low. Without that consistent anti-inflammatory support, the body can become more prone to chronic, low-grade inflammation.

This shift can show up in ways that feel disconnected from one another but are deeply related:

• Hot flashes that seem to come out of nowhere

• Increasing insulin resistance or changes in how your body handles blood sugar

• A rise in cardiovascular risk factors

• Gradual loss of bone density

• Flare-ups in autoimmune conditions or new sensitivities

These aren’t random. They are part of a larger physiological shift.

Inflammation is not inherently bad. It is a necessary and protective response. But when it becomes chronic, it can start to amplify many of the symptoms women experience during this stage of life.

And there’s yet another layer: chronic stress.

Stress hormones like cortisol can further increase inflammatory signaling in the body. When combined with fluctuating or declining estrogen, this can create a perfect storm, where the body feels like it’s constantly in a heightened state of reactivity.

This is why supporting your body during perimenopause and menopause isn’t just about managing symptoms. It is about understanding the underlying shifts that are happening and working with them, not against them.

Because this isn’t simply “aging.” It’s a complex, whole-body transition that deserves a more thoughtful and supportive approach.

Next time, I’ll discuss holistic ways that you can support yourself through the perimenopause transition.
