Adenomyosis: what it is and how it differs

In endometriosis, lining-like tissue grows outside the uterus; in adenomyosis, it's within the uterine muscle. The two can occur together, and symptoms can overlap.

Adenomyosis may cause heavier periods, more painful periods, or a feeling of pressure. Some people have few symptoms.

Diagnosis often involves history, examination and imaging such as ultrasound. Management focuses on controlling symptoms, using options decided together with a clinician.

If you have heavy or painful periods, a specialist can assess whether adenomyosis (or a related condition) is involved and discuss options.
