Flushing, palpitations, headaches, itchy skin, gut upset, broken sleep... and a body that suddenly feels more sensitive. If that sounds familiar in your 40s, there's a lot going on beneath the surface.
Mast cells are the immune system's alarm cells. They release histamine and inflammatory messengers, and research suggests that shifting oestrogen and ongoing stress may make them more reactive. That could help explain why some women feel more inflamed, more sensitive and more "on edge" in perimenopause.
The science is still emerging. Most of the link so far comes from lab, animal and observational studies, and many of these symptoms overlap with perimenopause itself, thyroid and iron changes, so a proper health provider assessment always comes first. Herbs like quercetin, vitex, schisandra and grape seed are popular, but the human evidence is small and early.
Swipe to see how mast cells, inflammation, immune balance and hormones may be connected, what the evidence really says, and the steps that can help you feel more settled.
