What Could Trigger Enlarged Uterus? 12 Possible Causes

Adenomyosis

Adenomyosis is a condition wherein the inner lining of the uterus or the endometrium breaks through the muscle wall of the uterus or myometrium. As a result, endometrial glands and stroma in the uterine walls result in a diffusely enlarged uterus. In women with adenomyosis, the uterus may double or triple in size but does not exceed the size of a uterus at 12 weeks’ gestation.

The incidence and prevalence of an enlarged uterus in women with adenomyosis are unknown, which makes early diagnosis challenging. Developing adenomyosis is higher in women diagnosed with uterine fibroids, endometriosis, and pelvic pain.

Symptoms of adenomyosis include heavy menstrual bleeding, pelvic pain, and pain during sexual intercourse. There is no cure for adenomyosis, but treatment options include hormonal therapy, pain medication, and surgery. Some women may also choose to undergo a hysterectomy which involves the surgical removal of the uterus to reduce uterus size and relieve other symptoms. 

Adenomyosis is a chronic condition, so there is no way to prevent it. However, early diagnosis and treatment can help to manage symptoms and improve quality of life.
