What Is Red Degeneration of a Uterine Fibroid Tumor?

Fibroids are typically benign growths that form in the uterus. While many do not cause symptoms, some fibroids cause pain and bleeding. Red degeneration of a fibroid typically occurs in pregnancy.

Pregnancy and Fibroids

The process of pregnancy stimulates estrogen production. This can trigger already present-fibroids to grow larger.

Incidence

Red degeneration occurs in about 10 percent of fibroids, according to Northern Westchester Hospital. They typically manifest during the middle weeks of pregnancy but can occur any time, even in non-pregnant women.

Causes

The excess estrogen triggers the fibroid to grow faster than its blood supply can support it. The lack of oxygen and nutrients causes the fibroid to turn red and break down.

Symptoms and Complications

Red degeneration causes severe stomach pain and contractions. It can lead to miscarriage or early labor, according to Women's Health, a London-based health center.

Treatment

Treatment consists of pain medication and possibly medications to stop the contractions. You cannot perform surgery or other procedures during pregnancy due to the risk of bleeding, according to Northern Westchester Hospital. Your doctor can offer guidance post-pregnancy on whether you should consider treatment.
