Is Excess Oestrogen Behind Your Symptoms? What Every Woman Needs to Know
Heavy periods. Sore breasts. Mood swings that floor you. Unexplained weight gain. If any of this sounds familiar, you’re not alone — and more importantly, there may be a very specific reason behind what you’re experiencing.
As a Registered Nutritional Therapist and women’s health nutritionist based in Southport, I work with women across Merseyside, Lancashire and the wider UK who are struggling with hormonal symptoms — many of whom have never been told that excess oestrogen could be a significant driver of what they’re going through.
This post brings together everything I shared in a recent series on Instagram, covering the role of excess oestrogen in female health conditions, and the simple, practical steps you can take to support your body in rebalancing.
Could Excess Oestrogen Be Behind Your Diagnosis?
Oestrogen dominance — where oestrogen levels are too high relative to progesterone — is more common than many women realise. It can be a significant driver in a range of conditions, including:
Endometriosis
Fibroids
PMS (premenstrual syndrome)
PMDD (premenstrual dysphoric disorder)
PCOS and PMOS
And if you’re in perimenopause, oestrogen imbalance can sit behind some of the most disruptive symptoms of that transition, including heavy or irregular periods, breast tenderness, migraines, mood swings and unexplained weight gain.
Many women carry these symptoms for years. They manage. They cope. But they’re rarely told that the levels of oestrogen circulating in their body could be fuelling what they experience every single month.
Step One: Feed Your Body More Fibre
One of the simplest and most powerful steps you can take is increasing the fibre in your diet. Think of fibre like a brush sweeping through your digestive system — clearing out waste products, including excess hormones like oestrogen, and carrying them out of the body.
Without enough fibre and regular bowel movements, that oestrogen doesn’t make it out. Instead, it can get reabsorbed back into the bloodstream, keeping levels higher than they should be.
Great sources of fibre to include daily:
Wholemeal bread, brown rice, oats and wholegrain pasta
Beans and pulses such as lentils, chickpeas and kidney beans
Seeds including chia seeds and flaxseed
Your Hormone Heroes: Cruciferous Vegetables
If there’s one food group to prioritise for hormonal balance, it’s cruciferous vegetables. They contain powerful natural compounds — including indole-3-carbinol — that actively support your liver’s ability to process and eliminate excess oestrogen. They’re also an excellent source of fibre, giving you a double dose of hormone support in every serving.
Your hormone hero list includes:
Broccoli
Kale
Cabbage
Brussels sprouts
Cauliflower
Rocket
Pak choi
Watercress
Spring greens
Radishes
Aim for at least one portion every day. Steamed, roasted, raw or stir-fried — it all counts.
Love Your Liver: Why It Matters for Hormonal Health
Your liver is your body’s main detoxification organ and plays a central role in processing and clearing excess oestrogen. But it isn’t just hormones it’s dealing with. Every day it’s also filtering out compounds from skincare, haircare, cosmetics, household cleaning products, alcohol, medications and environmental pollution.
When that load becomes too heavy, oestrogen clearance can be compromised — and levels can creep up higher than they should be. Supporting your liver isn’t a luxury. It’s essential.
These foods actively support your liver’s detoxification pathways:
Garlic and onions — rich in sulphur compounds that help neutralise and eliminate toxins
Leeks and chives — also from the sulphur-rich allium family
Beetroot — supports bile production to help carry waste products out of the body
Citrus fruits — packed with vitamin C and antioxidants that protect liver cells
Cruciferous vegetables — work directly on the oestrogen processing pathways in the liver
Hidden Hormone Disruptors in Everyday Products
Here’s a statistic that tends to stop women in their tracks: according to research by the Environmental Working Group, the average woman applies 168 chemicals to her body every single day through personal care products, cosmetics, perfumes and feminine hygiene products alone.
Many of these chemicals are endocrine disruptors — substances that interfere with your body’s hormonal system by mimicking, blocking or altering the way your natural hormones work. Some of the most common, such as parabens and phthalates, actually mimic oestrogen in the body, adding to the overall hormonal load your liver and digestive system are working so hard to clear.
The good news is that there are brilliant natural and clean alternatives available. Some simple swaps to consider:
Conventional moisturiser → natural or organic alternative
Standard shampoo and conditioner → sulphate and paraben-free options
Everyday cosmetics → clean beauty brands
Household cleaning products → natural, fragrance-free options
Synthetic home fragrances → essential oil diffusers or natural candles
You don't need to overhaul everything overnight — and you don't need to spend hours researching every product label either. As a Tropic ambassador, I recommend their range wholeheartedly. Every product is natural, organic and free from the hormone-disrupting chemicals we've been talking about. It's one of the easiest and most trustworthy switches you can make.

Want a Clear Picture of What Your Hormones Are Actually Doing?
The tips above are a brilliant starting point. But for women with a diagnosis — or a long list of symptoms and no real answers — getting a detailed picture of what is happening with your hormones can be genuinely life-changing.
Dried urine hormone testing is one of the most comprehensive tools available. Unlike a standard blood test, it goes beyond simply measuring hormone levels. It shows how well your body is actually processing and clearing oestrogen — giving you and your practitioner the insight needed to put a truly personalised plan in place.
This type of testing can be particularly valuable if you are living with or experiencing:
Endometriosis or fibroids
PMS or PMDD
PCOS or PMOS
Perimenopause symptoms including heavy periods, breast tenderness, migraines, mood swings or weight gain
Special Offer — June 2026
Throughout June, I am offering a free 45-minute results interpretation consultation to any woman who books a dried urine hormone test through my practice. Together we’ll go through your results in detail, explore what they mean for your health, and map out your next steps with clarity and confidence.
