What could be the cause?
The exact cause of uterine fibroids is still unclear. But following factors are believed to cause uterine fibroids.
Genetic mutations: In most of the cases, fibroids may occur as a result of genetic alterations in the healthy uterine muscle cells.
Hormonal changes: The hormones, estrogen and progesterone, causes the regeneration of uterine lining during each menstrual cycle. These hormones stimulate the growth of the fibroids in the uterus.
Other causes: The factors that help to maintain normal body mechanisms, such as insulin-like growth factor may also cause uterine fibroids.
Abnormal hormone levels:Due to an increase in the levels of estrogen and progesterone during pregnancy, most of the pregnant women develop fibroids in the uterus which may shrink off after the pregnancy.
