Sophie Richards has said she felt dismissed by medics for years, despite being "bed-bound" for a fortnight each month. This was until she received her diagnosis and transformed her life.

The women's health practitioner and presenter of 'The Finally Found Podcast' revealed she felt like she was "screaming at doctors" that something was seriously wrong, yet was repeatedly told it was "just IBS or just painful periods– it's 'part of being a woman'".

She’d experience “agonising pain”, brain fog, nausea, fatigue and extremely heavy, 10-day-long periods, until she was diagnosed at 21. Now 29, Richards says it wasn’t that doctors didn’t want to help, they just didn’t have answers.

Endometriosis UK calculates that 10% of women battle the chronic condition – where tissues similar to the uterine lining develop outside the womb – yet it takes roughly eight years on average from the initial GP appointment to secure a diagnosis.

There is currently no cure for endometriosis, and Cardiff-based Richards was told there was nothing more they could do to alleviate her symptoms, except a hysterectomy – “That this was my life, and I just thought, ‘there is no way I can carry on in this agonising pain’.”

She reveals the agony peaked at two points each month. "In the middle of my cycle and then just before my period, the luteal phase, were absolutely excruciating. For at least two weeks of the month, I was bed-bound."

One thing Richards noticed was that her symptoms often got worse after certain meals. “I started to do a little bit more digging and some research, and saw this link between inflammation and endometriosis."

Because of this, she enrolled in a course to become a women’s health practitioner, began eliminating inflammatory foods from her diet, and shared her progress on Instagram.

“I was really sceptical. I thought, ‘How on earth are lifestyle changes going to help when I’ve had four surgeries (including two for egg freezing) and they’re all telling me nothing’s going to work. But I just thought, you know what? What’s the harm?”

Previously, she ate what she considers a regular diet for someone of university age “with no nutritional background or information”.

She says: “I thought what was healthy was a vegetable lasagne instead of a meat lasagne – it was very processed, I was eating lots of protein bars.

"I grew up thinking calories were bad, so anything that had ‘low calorie’ and ‘low fat’ I thought was a green sign. In my mind I was eating healthy food but the reality was very, very different.”

Richards soon began implementing little daily habits and immediately started to feel better. “My periods are a little bit lighter, which was crazy because I used to flood through all my pads and tampons, and I wasn’t flooding anymore.”

Now she has published her debut book, The Anti-Inflammatory 30-Day Reset, an accumulation of everything she has learned, along with expert knowledge and recipes, split into six ‘pillars’ of an anti-inflammatory lifestyle: food, gut health, detoxification, sleep, stress, and movement.

Her diet and how she viewed food were the biggest changes she made. “There were some meals that I would eat and, straight after it, I’d be doubled over [with] a big swollen belly, and just didn’t understand why.

“Looking back, it was more heavily processed foods. Basically, the more complicated the ingredients were, the more artificial the chemical sweeteners, the worse the symptoms were. Artificial carbohydrates were my biggest problem. Things like white pasta, very processed breads…”

She said that the grain-free seeded bread in her book is “actually the only bread I can have that doesn’t make me feel awful and it’s because it’s full of healthy, whole food ingredients rather than processed stuff.

“I used to eat gluten and it would swell me up. I’d have this huge kind of migraine after it. So processed foods, gluten and dairy I’d say were the three key things.

“I do have one piece of red meat a week, and I try my best to make sure it’s as high quality as possible because anaemia is something a lot of people with endometriosis struggle with. And I know I can struggle with it from time to time because of that blood loss."

While changing her diet helped Richards, she knows that people with the condition are "unique" and not everyone has the same symptoms. Inflammation is a complicated topic we don’t even fully understand yet, she admitted.

“But, from what we do know, it’s very clear that there are different points in the cycle that are more inflammatory. And it is really clear that some foods can cause inflammation over others. The general consensus is [to] move to a whole food way of eating.

“When something doesn’t have a label, it’s a good sign. So I always think; meat, fish, fruit, veg, nuts, seeds, grains, legumes. When you move to that way of eating, you lower inflammation. Fibre is so important to the gut, it helps with hormones, and helps with inflammation.”

“First of all, remember it’s totally normal. These foods are built to make you feel addicted to them. Also, off the back of Christmas, when you have that high blood sugar going on, you tend to crave more as well.”

But if you’re able to balance your blood sugar by eating meals high in protein, fats and ‘nature’s carbohydrates’, “and when you understand the ‘why’ behind something, you’re able to sit with the craving a little bit more.

“The more sugar you eat, typically, the more you will crave it. Now I don’t eat any rubbish, and I don’t crave any rubbish because I’ve been eating this way for so long.”

But that doesn’t mean no sweet treats. "It’s not about giving up anything. It’s just about making those healthier swaps. There are plenty of sweet treats that don’t take you on that roller coaster of cravings.”

Living an anti-inflammatory lifestyle has also helped Richards’ mood dramatically improve. “I didn’t even realise I was struggling until I’d almost come out of the fog. I wasn’t feeling down all the time.”

Of course, the condition is still there, but it doesn’t take over her life in the same way. “I have endometriosis, but because I’m not feeling the symptoms of it anymore, I can live with anything if it’s not affecting me.”
