With adenomyosis, the tissue grows into the walls of the uterus.
Although they are two distinct conditions, adenomyosis and endometriosis share symptoms such as painful periods andheavy menstrual bleeding.
Because of this, they are often mistaken for one another.

They can even occur at the same time.
Despite these changes, the endometrial tissues remain functional and are shed with each period, causing bleeding.
The tissues that extend beyond the uterus in endometriosis are different.
While they are similar to endometrial tissue, they are not exactly like what’s in the uterus.
These tissues function similarlybreaking down and bleeding with each periodbut ultimately become trapped in the organs they invade.
This can lead to scarring and adhesions (the sticking together of tissues).
Even so, there are certain signs that can help differentiate them.
Causes
The exact cause of adenomyosis and endometriosis is unknown.
However, certain risk factors can increase the likelihood of developing these conditions.
Your surgeon may also take an endometrial biopsy for further testing.
While there is no cure for these conditions, they can be well-managed.
Symptoms of both include pelvic pain and heavy menstrual periods, but there are some unique symptoms as well.
Possible treatments include over-the-counter pain relievers, hormonal contraceptives, and hysterectomy.
Frequently Asked Questions
Endometriosis is more likely to cause symptoms than adenomyosis.
Many individuals with adenomyosis do not know they have it because of the lack of symptoms.
Adenomyosis may lead toabdominal distention.
The uterus can become enlarged when its walls become overly thick due to endometrial tissue growth.
This can cause the abdomen to swell.
While adenomyosis does not cause endometriosis, the two conditions are linked.
Individuals with endometriosis are more likely to be diagnosed with adenomyosis than women without a disorder of the endometrium.
