Introduction
Painful, heavy periods and a uterus that feels constantly tender or swollen get written off as "just part of being a woman" far too often. For many, those symptoms are actually adenomyosis — increasingly recognised, but still frequently misdiagnosed.
What Is Adenomyosis?
Adenomyosis happens when the tissue that normally lines the uterus grows into the muscular wall itself. Each month, that misplaced tissue still thickens, breaks down, and bleeds with your cycle — but trapped inside the muscle wall, it has nowhere to go. The result is an enlarged uterus, and often, real pain.
It's similar to endometriosis in some ways. Endometriosis involves endometrial-like tissue growing outside the uterus and in the pelvis, while adenomyosis involves it growing within the uterine muscle wall. It's also possible to have both at once.
What Are the Symptoms of Adenomyosis?
Severity varies widely — some women barely notice, others find it dominates daily life. Common signs include heavy or prolonged periods, period pain that worsens over time, chronic pelvic pain beyond just your period, pressure or bloating low in the abdomen, pain during intercourse, and sometimes difficulty conceiving.
Because these symptoms overlap with so many other gynaecological conditions, adenomyosis is genuinely hard to diagnose on symptoms alone — which is exactly why imaging matters.
How Is Adenomyosis Diagnosed?
It used to be that adenomyosis could only be confirmed after a hysterectomy, examining the tissue directly. Imaging has changed that: it can now typically be identified through detailed ultrasound while the uterus stays exactly where it is.
A detailed ultrasound scan lets our specialists examine the uterine wall closely, looking for the tell-tale signs — thickening of the muscle layer, small cyst-like areas, an enlarged or irregularly shaped uterus. An MRI may be added for further clarity in some cases, particularly where the picture isn't clear or surgical planning is needed.
The scan itself is painless and non-invasive. For many women, simply having a name for what they've lived with for years — after being told it's normal — brings real relief on its own.
What Does Adenomyosis Mean for Fertility?
This is usually the question people actually want answered, and the honest reply is: it depends. For some women, adenomyosis has no real impact on conceiving or carrying a pregnancy. For others, it's linked to a higher risk of difficulty conceiving, miscarriage, or later pregnancy complications, largely because an altered uterine environment can affect implantation.
What's important to hold onto is this: adenomyosis does not rule out a healthy pregnancy. Many women conceive naturally, or with support, once the condition is identified and managed as part of a personalised fertility plan.
What Treatment Options Are Available?
Treatment depends on your symptoms, severity, and fertility goals. Options range from hormonal treatment to manage pain and bleeding, to fertility-focused management tailored to protect implantation if you're trying to conceive, through to surgical options in more severe cases where fertility isn't the immediate priority. Your specialist will work through what fits both your symptoms and your plans.
Getting the Clarity You Deserve
If heavy, painful periods have left you with a nagging feeling that something isn't right, you deserve more than being told it's normal. A detailed ultrasound can give you real answers — and with the right diagnosis, a clear path forward, whether that's symptom relief, fertility planning, or both.
