The short explanation
Adenomyosis is a condition where tissue like the lining of the womb grows into the muscle wall of the womb. During periods this tissue bleeds and swells within the muscle, which can make the womb larger, described as bulky on a scan, and cause heavy, painful periods. It is common in women in their forties and in those who have had children. It is not cancer. Treatment depends on how much the symptoms affect you, your age and whether you might want a pregnancy. Options include pain relief, hormonal treatments such as a hormonal IUD or other hormonal methods, treatments to reduce bleeding and, for some women whose family is complete and symptoms are severe, surgery. Symptoms usually settle after menopause.
What depends on your situation
The parts of this that change from woman to woman. Uncertainty is stated, not hidden.
- Your doctor may check your blood count, because years of heavy bleeding can cause anaemia.
- Adenomyosis can occur together with fibroids or endometriosis, and the scan may not separate them clearly. An MRI is sometimes used if the picture is unclear.
- It is worth thinking about what matters most to you, such as controlling bleeding, reducing pain or avoiding surgery, so you can discuss options that fit your life.
What this answer cannot determine
The boundary of online education. These need a clinician who can see you.
- This answer cannot tell how severe your adenomyosis is or which treatment will suit you. A gynaecologist needs to examine you and review the scan and your history.
Questions for your clinician
Take these with you. You can add any of them to an appointment card.
- How sure are we that this is adenomyosis and not fibroids?
- What are my options for controlling the pain and bleeding?
- Is a hormonal IUD suitable for me?
- Should my blood count be checked for anaemia?
- When would surgery be considered?
When to seek help
Clinician-approved guidance for this topic. When in doubt, being seen is never the wrong choice.
Emergency — call 112 now
- Call 112 or go to the nearest emergency department if you have very heavy bleeding with fainting, chest pain or breathlessness.
Get help the same day
- Get care the same day if you are soaking through pads every hour or feel dizzy and weak.
Raise it at a routine appointment
- Book an appointment with a gynaecologist to discuss your report and treatment options.
