What Is Adenomyosis?

Adenomyosis is a condition of the uterus (womb) where the cells that usually form a lining inside the uterus also grow in the uterus's muscle wall.


The term adenomyosis comes from the words:

adeno – gland myo – muscle and osis – condition

  • Where does Adenomyosis occur?

Adenomyosis is most likely to occur in the muscle layer of the back wall of the uterus but can occur anywhere in the muscle layer. If Adenomyosis is concentrated in one area, it can lead to a mass called an adenomyoma.

AdenomyomaAn adenomyoma is a focal region of adenomyosis resulting in a mass, which is difficult to distinguish from a uterine fibroid, although in general the degree to which the contour of the uterus is distorted is less marked in adenomyosis.

Can an enlarged uterus cause constipation?

In short, yes. General symptoms of an enlarged uterus, which can be caused by fibroids and other conditions as well, may include: 

Bloating / Constipation / Unexplained weight gain or a swollen lower belly / Frequent urination / Pain

What are the signs and symptoms of Adenomyosis? 

The most common symptoms are: 

abnormal or heavy menstrual bleeding/painful periods /often after years without pain/pain with intercourse (dyspareunia) / bleeding between periods / on vaginal examination, the uterus feels enlarged and is usually tender to touch  / excessive menstrual bleeding can lead to symptoms of anemia (deficiency in the number of red blood cells) or iron deficiency such as tiredness

What are the causes?

The cause of Adenomyosis is unknown; however, there are several theories: 

The lining cells invade into the muscle layer as a result of surgery / Lining tissue was deposited into the uterine muscle early in fetal life, before birth / Inflammation of the lining after childbirth causes cells to pass into the weakened muscle layer

Adenomyosis is only seen in women in their reproductive years because its growth requires ostrogen. After menopause, Adenomyosis usually goes away because of the lack of oestrogen.

Oestrogen:Is one of the main female sex hormones. While both women and men produce oestrogen, it plays a more significant role in women's bodies. Oestrogen is produced by your hormonal (endocrine) system and moves through the bloodstream. In the female body, oestrogen is needed for puberty.
