Keto and Endometriosis: What the Research Shows
The ketogenic diet, a low-carbohydrate high-fat eating pattern, has gained attention for its potential effects on chronic inflammatory conditions. Endometriosis, where tissue similar to the uterine lining grows outside the uterus, creates inflammation and pain that often worsens during menstruation. Emerging evidence suggests dietary approaches like keto may influence these symptoms through multiple pathways.
How Ketosis Affects Inflammation
Ketones produced during nutritional ketosis appear to reduce inflammatory markers like IL-6 and TNF-alpha. A 2019 study in Frontiers in Endocrinology found ketogenic diets decreased systemic inflammation in people with type 2 diabetes, another condition with inflammatory components. While not endometriosis-specific, this mechanism may be relevant as endometriosis lesions create local inflammation. the anti-inflammatory effects of keto
Hormonal Influences
Endometriosis is estrogen-dependent. The ketogenic diet may lower circulating estrogen levels by reducing body fat, where estrogen is stored. Research in Nutrition & Metabolism showed women with PCOS (another hormone-sensitive condition) experienced improved hormone profiles on keto. Though PCOS differs from endometriosis, both conditions respond to hormonal modulation. keto macros for hormone balance
Pain Management Considerations
Some women report reduced pelvic pain on keto, possibly due to:
- Lower prostaglandin production (compounds that intensify menstrual cramps)
- Stabilised blood sugar reducing pain perception
- Increased consumption of anti-inflammatory omega-3s found in oily fish
What This Means in Practice
UK supermarkets make keto-friendly options accessible. Sainsbury’s sells 500g packs of Scottish salmon for £5.50, rich in anti-inflammatory fats. Seasonal British vegetables like kale (79p per bunch at Tesco) provide fibre without excess carbs. During colder months, bone broth made with Morrisons beef bones (£2.30/kg) may support gut health – important as endometriosis and gut issues often coexist.
Potential Cautions
Those with endometriosis considering keto should:
- Monitor iron levels if experiencing heavy periods
- Ensure adequate magnesium from leafy greens or supplements
- Gradually reduce carbs to avoid initial energy dips
Frequently Asked Questions
Can keto cure endometriosis?
No diet can cure endometriosis, but some women find symptom relief through keto’s anti-inflammatory effects. Always consult your GP before making dietary changes alongside medical treatment.
How long until I might notice changes?
Some report differences within 2-3 menstrual cycles, but individual responses vary. Tracking symptoms in the Keto Dieting app can help identify patterns.
Are sweeteners okay with endometriosis?
Some artificial sweeteners may disrupt gut bacteria. Small amounts of erythritol or stevia (available at Waitrose) are generally better tolerated.
The Bottom Line
The ketogenic diet shows theoretical promise for endometriosis through inflammation reduction and hormonal effects, though direct research remains limited. A focus on quality fats, moderate protein and low-glycemic vegetables may support conventional treatments. Many find keeping carbs below 50g daily helps maintain ketosis. If you’d rather not do the macro maths yourself, the Keto Dieting app does it for you on Google Play and the App Store.
