Endometriosis Diet: Foods, Nutrition Strategies & Anti-Inflammatory Eating Tips

Learn what the research says about the best diet for endometriosis and helpful nutrition strategies

As a digestive health dietitian, I’m seeing more clients with diagnosed or suspected endometriosis as the condition often presents alongside digestive concerns. Endometriosis is very common, affecting an estimated 1 in 7 women and individuals assigned female at birth. While research is still evolving, we are learning more about how nutrition and lifestyle strategies may help support symptom management and overall quality of life. In this post, we’ll explore what endometriosis is, common symptoms, and nutrition strategies that may help support you and your body. 

Key Takeaways

• Endometriosis is a chronic inflammatory condition that can affect pain, digestion, energy, mood, and fertility.  

• Nutrition won’t cure endometriosis, but anti-inflammatory eating patterns may help support symptom management.  

• Focus on adding nutrient-dense foods like leafy greens, berries, fatty fish, nuts, seeds, and healthy fats instead of restrictive diets.  

• Digestive symptoms are common, and nutrition strategies should be individualized and sustainable. 

What is Endometriosis? 

Endometriosis is a chronic inflammatory condition where tissue similar to the lining of the uterus grows outside of the uterus. This tissue responds to hormonal changes during the menstrual cycle, particularly estrogen. The growth of these lesions contributes to inflammation, scarring, adhesions, and pain. These endometrial “implants” are commonly found around the ovaries, fallopian tubes, bowels, and bladder. In rare cases they have also been found in other areas of the body, such as the lungs and brain. 

What are the Symptoms of Endometriosis? 

Endometriosis presents differently from person to person. Some individuals experience mild symptoms, while others experience debilitating pain that significantly impacts daily life. Symptom severity does not always correlate with the extent of the disease. 

Common symptoms include: 

• Severe menstrual pain and/or heavy bleeding  

• Pelvic pain  

• Pain during or after sex  

• Infertility  

Other symptoms may include: 

• Bloating  

• Diarrhea  

• Constipation  

• Abdominal pain  

• Painful bowel movements  

• Frequent urination or urinary urgency  

• Fatigue and sleep difficulties  

• Headaches or dizziness during periods  

• Anxiety, stress, or depression  

Symptoms often begin during adolescence and may improve after menopause, as endometriosis is influenced by estrogen levels. Because endometriosis can mimic other conditions, particularly digestive disorders like irritable bowel syndrome, diagnosis can be challenging. If you suspect you may have endometriosis, it’s important to speak with your healthcare provider for further assessment. This self assessment tool is useful to complete and bring with you to your provider if you suspect you may have endometriosis.  

What Causes Endometriosis? 

The exact cause of endometriosis remains unclear, but research suggests it is likely influenced by a combination of genetic, hormonal, immune, and environmental factors. Factors associated with increased risk may include: 

• A family history of endometriosis (especially a first-degree relative)  

• Early menstruation (early menarche)  

• Lower birth weight  

• Lower body weight  

• Higher alcohol intake  

• Immune and inflammatory factors  

• Previous abdominal surgery  

Currently, there is no cure for endometriosis. However, treatment options such as hormonal therapies, medications, surgery, pelvic floor physiotherapy, psychotherapy, nutrition support, and complementary therapies like acupuncture may help improve symptoms and quality of life.

How Does Endometriosis Affect Digestion, Inflammation, and Energy? 

Endometriosis is associated with chronic inflammation and an overactive immune response. Many individuals experience persistent pain, which can significantly impact energy levels, sleep, mood, and overall well-being. Digestive symptoms are also very common and may include: 

• Bloating  

• Constipation  

• Diarrhea  

• Abdominal pain  

• Painful bowel movements  

In some cases, endometrial-like tissue may grow near or around the bowel or bladder, contributing to digestive and urinary symptoms. There is also significant overlap between endometriosis and disorders of gut-brain interaction, including irritable bowel syndrome (IBS). Chronic pain and stress can further influence digestion through the gut-brain connection. 

Can Diet Help Endometriosis? 

While nutrition cannot cure endometriosis, some evidence suggests that anti-inflammatory eating patterns may help support symptom management and overall health. For individuals experiencing digestive symptoms, a low FODMAP diet may sometimes be helpful, particularly if IBS symptoms are also present. However, this approach is not appropriate or beneficial for everyone and should ideally be done under the guidance of a registered dietitian trained in digestive health. 

What is the Best Diet for Endometriosis?

There is no single diet that cures endometriosis. However, a Mediterranean-style eating pattern rich in vegetables, fruit, legumes, nuts, seeds, fish, and olive oil may help support overall health and symptom management.

Foods That May Help Reduce Endometriosis Symptoms 

An anti-inflammatory eating pattern focused on adding nutrient-dense foods that support overall health may benefit individuals with endometriosis. Some foods that are considered anti-inflammatory include:  

• Leafy greens like spinach, kale, and Swiss chard  

• Vegetables such as broccoli, Brussels sprouts, eggplant, tomatoes, and bell peppers  

• Berries, including blueberries, strawberries, and raspberries  

• Fatty fish such as salmon, mackerel, and sardines  

• Nuts and seeds including walnuts, chia seeds, flaxseeds, and almonds  

• Healthy fats like extra virgin olive oil, avocados, and olives  

• Herbs and spices such as turmeric, ginger, garlic, and cinnamon  

• Dark chocolate 

Aim for variety and focus on adding foods rather than creating overly restrictive rules. 

Foods That Some People Choose to Limit

Nutrition Strategies to Support Hormone Balance and Endometriosis Symptom Management 

When supporting endometriosis nutritionally, I prefer an “add-in” approach rather than elimination diets. Many diets marketed online as “curing” endometriosis are unnecessarily restrictive and often unsustainable. Eating enough food, eating consistently, and including a variety of nutrients is important for supporting hormone health, energy, immune function, and stress management. 

Here are some simple nutrition strategies you can try to boost your intake of anti-inflammatory foods: 

• Add 1 handful of frozen blueberries and some chia seeds and hemp hearts to your yogurt  

• Add berries to your oatmeal, yogurt, or smoothies. You can try this delicious berry monster smoothie or berry baked oatmeal  

• Add spinach or kale to smoothies, stir fries, pasta dishes, soups or stews, or throw a handful in scrambled eggs 

• Plan for fish on your weekly meal rotation at least once per week. I love this salmon recipe, or this easy poached fish recipe  

• Include 1 handful of nuts or seeds at your afternoon snack alongside a piece of fruit  

• Add some dark chocolate to your day paired with nuts for your afternoon snack 

• Spread avocado on toast, add to a salad, or try this strawberry avocado salsa with whole grain crackers  

• Add nutrient dense energy balls or chia seed pudding to your snack rotation 

 Remember, small, sustainable changes often have a greater long-term impact than strict food rules! 

Can Supplements Help Endometriosis?

Some low-quality or emerging evidence suggests that certain supplements may modestly improve symptoms in some individuals, though research findings are mixed. 

These may include: 

• Omega-3 supplements containing EPA (500 mg) and DHA (200 mg)  

• Vitamin D supplementation of 2,000 IU  

• Palmitoylethanolamide (PEA) at 400 mg twice daily for pain support  

Before starting supplements, it’s important to speak with a healthcare provider or Registered Dietitian to determine what is appropriate for your individual needs. 

Common Endometriosis Diet Myths 

“You have to avoid gluten and dairy.” 

Not necessarily. While some individuals may notice digestive symptom improvement when reducing gluten or dairy, others experience no benefit. Symptoms may also be related to other conditions such as celiac disease, lactose intolerance, IBS, or non-celiac gluten sensitivity. Eliminating foods unnecessarily can make eating more stressful and restrictive, so it’s best to work with a registered dietitian before removing major food groups. 

“Sugar feeds endometriosis lesions.” 

There is currently no evidence showing that sugar directly feeds endometriosis lesions. Endometriosis is hormonally driven, particularly by estrogen. 

“Diet can cure endometriosis.” 

There is currently no cure for endometriosis. Nutrition may help support symptom management and overall well-being, but diet alone is not a cure. 

“Seed oils cause endometriosis.” 

There is no evidence that seed oils cause endometriosis. Endometriosis is a complex condition influenced by genetics, hormones, immune factors, and the environment. 

“Soy worsens endometriosis.” 

Soy contains phytoestrogens, which has led to concern because endometriosis is estrogen sensitive. However, current evidence does not show that moderate soy intake worsens endometriosis, and soy foods may actually provide benefit for individuals with endometriosis.

Endometriosis is a complex condition that can affect many aspects of health, including digestion, energy, pain, and mental well-being. While nutrition is not a cure, gentle and sustainable dietary strategies may help support symptom management and improve quality of life. 

Rather than focusing on restriction, try emphasizing nourishment, variety, and consistency. Small changes can add up over time, and support from a healthcare team, including a qualified registered dietitian, can help you find an approach that works for your unique needs.
