Uterine fibroids are the most common benign tumors in the female reproductive organs and one of the most common tumors in the human body. They are also called fibroids and uterine fibroids. Since uterine fibroids are mainly formed by the proliferation of uterine smooth muscle cells, with a small amount of fibrous connective tissue existing as a supporting tissue, it is more accurate to call them uterine leiomyomas, or uterine fibroids for short.

Why do uterine fibroids cause abdominal pain? The reasons why uterine fibroids cause abdominal pain are as follows:

1. Oppression

Uterine fibroids can compress pelvic blood vessels, causing congestion or compress nerves, causing pain. Large subserosal fibroids that grow into the broad ligament can not only compress the nerves and blood vessels and cause pain, but can also compress the ureters and cause hydroureteral or renal pelvis, leading to low back pain.

2. Twist

Torsion of the pedicle of subserosal uterine fibroids or giant subserosal uterine fibroids in the fundus of the uterus can cause uterine torsion in some cases and can cause acute abdominal pain.

3. Transformation

Red degeneration of uterine fibroids is more common during pregnancy, manifesting as acute abdominal pain in the lower abdomen, accompanied by vomiting, fever and local tenderness of the tumor.

4. Submucosal uterine fibroids

Submucosal uterine fibroids can also cause abdominal pain during the discharge from the uterine cavity, but in general the discharge process is slow and gradual, and the cervix is ​​soft. The fibroids stimulate uterine contractions, causing paroxysmal lower abdominal discomfort, and rarely cause acute lower abdominal pain. When submucosal fibroids become infected and necrotic, followed by acute pelvic inflammatory disease, it can cause acute lower abdominal pain, but this is rare.

5. Infection

Necrotic infection of uterine fibroids causes pelvic inflammatory disease, adhesion and traction.

The above is an introduction to why uterine fibroids cause abdominal pain. From the above introduction, we can know that compression, torsion, degeneration, infection, etc. caused by uterine fibroids can cause abdominal pain. Therefore, for female friends who often experience abdominal pain, it is important to check in time, because it is likely caused by uterine fibroids!
