Perimenopause and Gut Health: Why Your Digestion Changes in Your 40s
Discover the oestrogen-gut connection and strategies to support your digestion through perimenopause.
PMS, Perimenopause, Thyroid & Fertility
Hormonal imbalances — from PMS and perimenopause to thyroid issues and fertility challenges — are deeply connected to gut health. As a functional medicine practitioner and nutritional therapist, Elena Rolt addresses the gut-hormone connection to help restore hormonal balance naturally.

Your gut contains a collection of bacteria called the 'estrobolome' that specifically regulates oestrogen levels. When gut bacteria are imbalanced, oestrogen can be reabsorbed instead of eliminated, leading to oestrogen dominance and symptoms like PMS, heavy periods, and hormonal acne. The gut also influences thyroid hormone conversion and cortisol regulation. Healing the gut is often essential for restoring hormonal balance.
Do any of these sound familiar?
What might be driving your symptoms:
We take a root-cause functional medicine approach to hormonal imbalance & gut health, using advanced gut microbiome testing and personalised nutritional therapy protocols.
We use advanced hormone testing alongside gut analysis to understand the full picture.
We target the specific gut bacteria that influence hormone metabolism and balance.
We create a comprehensive plan addressing both gut health and hormonal balance together.
"My PMS was debilitating every month. Elena's approach of healing my gut alongside hormone support has given me my life back. I barely notice my cycle now."

Yes. Many PMS and perimenopause symptoms — including mood swings, bloating, weight gain, and fatigue — are worsened by gut imbalances affecting hormone metabolism. A functional medicine approach that addresses both gut health and hormonal balance can significantly reduce these symptoms.
The gut plays a critical role in thyroid health: it's where T4 is converted to active T3, where thyroid-disrupting antibodies can be triggered by leaky gut, and where nutrient absorption (selenium, zinc, iodine) essential for thyroid function occurs. Healing the gut often improves thyroid markers.
