Effective Strategies from a Dietitian for Managing Endo Flare-Up Symptoms

Living with endometriosis can feel like riding a rollercoaster, especially during those challenging flare ups. As both an endometriosis dietitian and someone who lives with endo, I understand firsthand how overwhelming these can be.

Now I want to highlight one thing before we dive in, diet is not a cure for endometriosis. Anyone telling you otherwise is not qualified to be giving you any medical nutrition advice. Some people eat beautifully, prioritise their health, do all the "right" things and still have flares. That is not a failure on your part. That's the nature of this condition.

What we do know is that anti-inflammatory eating can reduce symptom severity over time for many/some people. Certain foods and eating patterns can genuinely help with the bloating, fatigue, and bowel symptoms that often come with endo.

Think of food as one tool in your endo toolkit a good one, but not the whole kit. The best outcomes I see are generally when people work alongside their multidisiplinary team (GP, Gynaecologist, Physiotherapist, Pain Specialist etc) AND support their body through nutrition.

What Does an Endometriosis Flare Actually Look Like?

Flares look different for everyone, but common ones I hear about from clients (and experience myself) include digestive issues (constipation, diarrhoea, bloating), the dreaded endo belly, chronic fatigue, pain ranging from cramps to completely debilitating and nausea that feels like a hangover you definitely didn't earn.

Best Diet for Managing Endometriosis Flares

There's no one best diet for managing endometriosis flares however, there are diet & lifestyle strategies you can use to help manage your endometriosis flareup's. What I recommend is having a toolkit of strategies you can pull from depending on what's going on for you on any given day. Here's how to approach the most common flare symptoms:

Managing Constipation

If you're experiencing constipation during a flare:

• Elevate your feet while on the toilet (using a small stool or even a cardboard box, it doesn't need to be fancy). This puts your body in a more natural position and genuinely makes a difference, trust me!

• Include natural laxative foods like 2x green kiwifruit and/or prunes every day

• Make sure you are eating enough fibre as most people aren't (grainy bread, fruits, veg, rolled oats, beans or lentils, brown rice, chia seeds etc)

• Consider a fibre supplement if needed (e.g. psyllium husk, PHGG etc)

• HYDRATE, HYDRATE, HYDRATE!! If you are dehydrated your body doesn't have enough fluid to help soften your stools making them much harder to pass

• Look into stool softeners for chronic constipation (discuss with your GP first)

Dealing with Diarrhoea

Loose stools during a flare can leave you dehydrated fast, so hydration is the first priority don't wait until you feel thirsty.

Beyond fluids, soluble fibre is your friend here. Foods like banana, avocado, oats, and psyllium husk help add bulk and slow things down. It can also help to temporarily pull back on common trigger foods like high-fat or fried foods, baked goods, high-sugar foods, dairy (for some people), alcohol, artificial sweeteners, and high-FODMAP foods like onion and garlic.

One important note: please don't try a low-FODMAP diet on your own. It's a therapeutic diet that needs guidance from a dietitian to do safely and effectively. Done incorrectly, it can actually make things worse.

Tackling Bloating

Bloating is one of the most frustrating endo symptoms because it's so visible, uncomfortable and can feel completely out of your control. A few strategies that often help:

• Eating smaller, more frequent meals

• Slowing down and chewing your food properly

• Skip the carbonated drinks and temporarily reduce gas-producing foods like brussels sprouts, broccoli, and legumes during a flare

• Peppermint is worth trying too, whether that's peppermint tea or a supplement

• And staying well hydrated and getting gentle movement in when you can

Fighting Fatigue

Endo fatigue can be debilitating and as its another invisible symptom, it's one that many people just don't understand. Nutrition plays a bigger role in managing it than most people realise.

Quite often in my clinic I see people who are not eating enough and/or skipping meals. When you're in pain, eating often feels like the last thing you want to do but skipping meals makes fatigue significantly worse. Aim for regular meals with some snacks and build them around a combination of protein, low-GI carbohydrates, healthy fats, and plenty of colour.

Low-GI carbs in particular are important because they're your body's preferred energy source and provide steady fuel rather than the spike and crash of high sugar or refined options. Think wholegrain bread or wraps, rolled oats or Weet-Bix, legumes, quinoa or potato/sweet potato with the skin on.

Pain Management

Firstly, it's important that you know that food won't reduce pain acutely. If you're mid-flare and hoping a meal will make the pain stop, that's not how it works unfortunately. However, dietary changes can reduce pain severity over time as part of a longer-term anti-inflammatory strategy.

During a flare, keep your meals simple. You don't need elaborate recipes when you're in pain. Eggs on grainy toast with spinach, tomato, and avo any time of day is a perfectly balanced, nourishing meal. So are baked beans on grainy toast with spinach or even a microwave meal. Next we want to make sure that you are hydrated as fatigue is a symptom of dehydration. Aim for a minimum of 8 glasses per day (everyone's specific requirements will be different). And finally, listen to your body's needs and rest if you can!

Although your diet won't reduce pain in the moment, dietary changes and anti-inflammatory foods may help reduce pain over time. Focus on the following:

• 2 serves of fruit and 5 serves veg/salad daily

• Choose whole grains (e.g. swap white bread to grainy wholemeal bread, choose rolled oats or weet-bix for breakfast, add legumes to mince dishes, swap to wholemeal pasta etc)

• 2-3 serves of fatty fish every week (e.g. salmon, mackeral, tuna, sardines etc) If you don't eat seafood, consider an omega 3 supplement

• Use extra virgin olive oil every day. EVOO contains oleocanthal which has been shown to work in a similar way to ibuprofen for reducing pain!
