Adenomyosis and endometriosis are often confused, and it makes sense why. They can share similar symptoms, but they affect the body in different ways ☝️
Adenomyosis happens within the uterus, where endometrial tissue (the lining of the uterus that sheds during the period) grows into the muscle wall. This can make the uterus feel enlarged and is often linked with heavier, more painful periods that can change over time. It’s more commonly identified in your 30s and 40s, usually through imaging like ultrasound or MRI.
Endometriosis sits outside the uterus. Endometrial tissue grows around areas like the ovaries or pelvis, and pain can show up before, during, or after your period. For some people it becomes ongoing. Periods don’t always change in the same way, which can make it harder to spot early. It often starts earlier, sometimes in your 20s or 30s, and is usually confirmed through laparoscopy. It can sometimes also be seen on ultrasound scans.
If your symptoms feel different to what they used to, or harder to manage, this kind of context can be a useful starting point.
You don’t need to have it all figured out. Understanding what could be behind your symptoms is often where these conversations begin 💫
