What Are Uterine Fibroids?

Uterine fibroids, or leiomyomata, are smooth muscle tumors that develop within or outside the wall of the uterus. The muscle cells start growing abnormally resulting in a fibroid, which is just a benign tumor. These fibroids are very common and almost all women might develop fibroids at one point in their lives. In most cases, they remain unnoticed as they are asymptomatic and harmless. Presence of fibroids is one of the leading causes of hysterectomies in women.

The actual cause of uterine fibroids is still unknown. Estrogen, the female hormone, seems to influence the growth of these benign tumors. Fibroids are seen only after puberty and it starts shrinking in size once menopause is achieved. This is mainly because of the dropping levels of estrogens in the blood after menopause. It normally develops after women reach the age of 3-years-old.

The most common factors that affect the development of uterine fibroids include:

  • Family history of fibroids – Women who have close relatives with this condition have increased chances of developing fibroids.

  • Birth control pills – The risk of fibroids reduces if the woman is on birth control pills.

  • Increased frequency of urination
  • Pain at the back or legs

Drugs that are generally used for the treatment of fibroids include Lupron, birth control pills, androgens, pain relievers, and iron. Among the surgical options, hysterectomy, myomectomy and focused ultrasound surgery are popular. Hysterectomy, the complete removal of uterus is a permanent method for preventing fibroids. In myomectomy only the fibroids are removed while the uterus is left as such.
