Adenomyosis: The Condition We Don’t Talk About Enough

Adenomyosis is a common yet under-recognised condition that can significantly impact daily life.

It occurs when endometrial-like tissue grows within the muscular wall of the uterus. This can change how the uterus functions — affecting its structure, contractility, and inflammatory environment.

Despite its prevalence, adenomyosis is still less understood and less frequently discussed than endometriosis.

More Than “Heavy Periods”

Adenomyosis is often associated with:

  • Heavy or prolonged menstrual bleeding

  • Painful periods

  • Pelvic pressure or fullness

But its impact can extend beyond these symptoms.

Changes within the uterine muscle can alter how the uterus contracts and responds throughout the menstrual cycle. This may contribute to:

  • Persistent pelvic discomfort

  • Lower back or hip pain

  • Fatigue (often linked to heavy bleeding and iron deficiency)

  • Gastrointestinal or bladder symptoms

For many, these symptoms don’t always feel obviously “gynaecological” — which can delay recognition and diagnosis.

The Role of Inflammation and Uterine Function

Emerging research suggests adenomyosis is not just structural, but also inflammatory.

The condition is associated with:

  • Increased local inflammation within the uterus

  • Altered nerve signalling and pain sensitivity

  • Changes in uterine contractility (how the uterus moves)

These factors together may explain why symptoms can feel both cyclical and persistent.

Why Diagnosis Can Be Delayed

Adenomyosis has historically been difficult to diagnose without surgery, though advances in imaging — particularly transvaginal ultrasound and MRI — have improved non-invasive detection.

Even so, many people experience years of symptoms before receiving clarity.

This is often due to:

  • Normalisation of heavy or painful periods

  • Symptom overlap with other conditions (including endometriosis and IBS)

  • Lack of awareness, both clinically and socially

A Whole-Person Approach to Care

Adenomyosis is not just a condition of the uterus — it can affect the whole body.

Management may involve a combination of approaches depending on symptoms, life stage and individual goals, including:

  • Hormonal therapies

  • Pain management strategies

  • Iron support where needed

  • Surgical options in some cases

At Elgin House, we take an integrated approach — considering hormonal, inflammatory and structural factors together to guide care.

When to Seek Support

If you’re experiencing:

  • Heavy or prolonged bleeding

  • Ongoing pelvic pain or pressure

  • Fatigue that feels disproportionate

  • Symptoms that don’t feel quite right

It’s worth exploring further.

You know your body best — and when something feels off, it deserves attention.
