Perimenopause constipation isn't just about fiber or hydration. Hormonal changes—especially fluctuating progesterone and declining estrogen—can slow gut motility and alter the gut microbiome, leading to constipation, bloating, and digestive discomfort. Learn what current research says, how magnesium may help, when symptoms need medical attention, and the practical strategies that made a difference in my own perimenopause journey.

Your gut microbiome does far more than digest food — it's actively managing your oestrogen through a community of bacteria called the estrobolome. In perimenopause, declining hormones disrupt this microbial ecosystem, which then worsens hormone signalling in return. The result? A vicious cycle that may be driving your bloating, brain fog, hot flashes, mood crashes and weight gain harder than you realise. Here's the science — and what the evidence says actually helps.
