Pelvic Pain: Why Looking Beyond Endometriosis Matters

Pelvic pain is not just frustrating, it can be debilitating. You might have pain that comes and goes, symptoms that change throughout your menstrual cycle, bloating or constipation, bladder symptoms, pain with sex, or discomfort that seems difficult to explain.

And sometimes, despite investigations and treatment, the pain persists and the questions continue to build up. Nothing is validating your experience.

One of the most helpful ways to understand persistent pelvic pain is to stop thinking about it as a problem belonging to one body part.

Pelvic pain can involve the reproductive system, bowel, bladder, pelvic floor and nervous system — and these systems can influence one another. This is why managing pelvic pain often requires a multidisciplinary approach rather than focusing solely on one diagnosis or treatment.

Nutrition is one piece of this bigger picture.

It won't be the answer for everyone, but for some people, supporting bowel function, adequate nutrition and the gut-brain connection can be an important part of reducing symptoms and improving quality of life.

What is pelvic pain?

Persistent pelvic pain is generally defined as pain in the pelvic or lower abdominal region that has been present for six months or more.

It can feel like:

Aching or cramping
Sharp or stabbing pain
Burning
Pressure or heaviness
Bloating or abdominal discomfort
Pain with sex
Pain when going to the toilet
Pain associated with your period or ovulation

Pelvic pain can have many different causes, including endometriosis, adenomyosis, bowel conditions, bladder conditions and pelvic floor dysfunction. But importantly, endometriosis and pelvic pain are not the same thing.

Endometriosis may kick off the pain, but pain can sometimes persist even when endometriosis is seemingly managed well. Over time, the nervous system, pelvic floor, bowel and other systems can become involved.

Why can pelvic pain continue?

Let’s break it down into initiators and perpetuators.

An initiator is something that may initially trigger pain. For example, endometriosis, an infection, surgery, injury or another painful experience. But the original trigger isn't necessarily what keeps the pain going. Over time, several systems can begin interacting:

Menstrual cycle ↔ Bowel ↔ Pelvic floor ↔ Nervous system ↔ Life load

For example, pain can cause the pelvic floor to become tense. A tense pelvic floor can make bowel emptying more difficult. Constipation and bloating can then increase abdominal and pelvic discomfort, further increasing the body's sensitivity to pain. This definitely doesn't mean the pain is "in your head".

Your pain is real.

It means there are multiple systems involved in how your body experiences and responds to pain. That gives us more opportunities to help.

Where does nutrition fit in?

Nutrition isn't a treatment for every cause of pelvic pain. However, the bowel and gut are closely connected to the pelvis, and bowel symptoms are very common in people experiencing persistent pelvic pain.

This makes nutrition particularly relevant when you're also experiencing:

Constipation
Bloating
Abdominal pain
Irritable bowel syndrome (IBS)
Diarrhoea
Difficult or incomplete bowel movements
Food-related anxiety or restriction

A dietitian can help identify whether your diet is contributing to your symptoms, without automatically putting you on a highly restrictive diet.

1. Supporting healthy bowel function

Constipation is more than simply "not going every day". You can still have constipation if you are regularly opening your bowels but:

Need to strain
Spend a long time on the toilet
Pass hard stools
Feel like you haven't completely emptied
Need to use specific manoeuvres to help you go

Constipation can contribute to abdominal discomfort and may interact with pelvic floor dysfunction.

Nutrition can help

Depending on your individual symptoms, this might mean looking at:

Fibre:
Increasing or adjusting fibre from foods such as oats, wholegrains, fruit, vegetables, legumes, nuts and seeds can support bowel health. But more fibre isn't always better. If you're very bloated or have certain types of IBS, suddenly increasing fibre can make symptoms worse.

Fluids:
Adequate fluid intake helps support softer stools, particularly when increasing fibre.

Regular eating:
Eating regularly can help establish a more predictable routine and strengthen your digestive system.

Food variety:
A broad range of plant foods provides different types of fibre and supports a diverse gut microbiome.

And sometimes, diet alone isn't enough. Laxatives, pelvic floor physiotherapy or other medical treatment may be appropriate depending on what's causing your constipation.

2. Bloating and IBS

Bloating can be particularly uncomfortable when you're already experiencing pelvic pain. For some people, IBS or other gut symptoms are an important part of the picture. In these situations, dietary strategies can sometimes reduce the amount of bloating, abdominal pain and bowel disturbance you're experiencing.

This might include:

Identifying individual food triggers
Adjusting meal size and timing
Reviewing fibre type and amount
Supporting regular bowel movements
Considering a structured low-FODMAP trial when appropriate

However, a low-FODMAP diet is not something we recommend everyone with pelvic pain needs to do. It is a therapeutic diet designed for specific gastrointestinal symptoms and is best undertaken with guidance from a dietitian. Unnecessary restriction can make eating more stressful, and stress is a perpetuator to pelvic pain. Hence, this can be a very counterintuitive strategy.

3. Eating enough matters too

When you're living with chronic pain, eating can become complicated. You might avoid foods because you're worried they will cause symptoms. You might skip meals when you're bloated. You might have a very small list of "safe" foods. Over time, this can lead to inadequate energy and nutrient intake.

More restriction isn't the solution to pelvic pain.

Your body still needs enough energy, protein, carbohydrates, fats, vitamins and minerals to support everyday functioning. A dietitian can help you find ways to meet your nutritional needs while also considering your individual gastrointestinal symptoms.

4. The gut-brain connection

Your gut and nervous system are constantly communicating via a pathway called the vagus nerve. When your nervous system is under a lot of stress, gut symptoms can become more noticeable. Likewise, ongoing bloating, constipation or abdominal pain can increase the overall stress placed on your nervous system.

For some people, approaches that address both sides of this relationship (such as gut–brain behavioural therapies alongside appropriate nutrition strategies) can be helpful.

Pelvic pain is a whole-body problem

Nutrition is just one part of the picture. Depending on your symptoms, your care team may include a:

GP or gynaecologist
Pelvic floor physiotherapist
Dietitian
Pain specialist
Psychologist or other mental health professional
Exercise physiologist

Other strategies such as pain education, appropriate medication, movement, sleep support, stress management and diaphragmatic breathing may also form part of treatment.

Our goal is to establish a greater quality of life for you in the long run, and that might not mean that you are completely pain free.
