Although no precise answers exist for the development of uterine fibroid tumors, there is a link between fibroids and estrogen production.

Fibroids do not develop until the body begins producing estrogen during the onset of menstruation. During the reproductive years, hormonal imbalance can cause fibroids to form and grow.  Hormonal imbalance occurs when estrogen and progesterone are not present in the proper proportions, often referred to as estrogen dominance. The most common imbalance that causes fibroids is low progesterone in ratio to estrogen.

Progesterone production decreases during the 30s and 40s.  When additional estrogen, such as the type found in birth control pills, hormone replacement therapy, and plant and environmental estrogens is brought into the mix, hormonal imbalance occurs.  Additionally, fibroid tumors may grow very quickly during pregnancy when the body is producing extra estrogen.

Primary Types of Uterine Fibroids

Uterine fibroids can be so tiny that you need a microscope to see them. However, they can grow very large. They may fill the entire uterus, and may weigh several pounds. Although it is possible for just one fibroid to develop, usually there are more than one.

There are four primary types of uterine fibroids, classified primarily according to location in the uterus:

Addressing Uterine Fibroids

Often, women are told that a fibroid condition is not medically addressed unless they become bothersome. However, at this point invasive procedures, such as surgery, hysterectomy, myomectomy, and embolization are generally the only options offered.  Therefore, it is a good idea to try and resolve this condition before they become too large or problematic. In many cases, if they have become large and problematic, but are not a threat to your health or vital organs, then you should still be able to attempt to shrink them naturally. 

Furthermore, uterine fibroids often shrink and disappear after menopause when the body stops producing as much estrogen.  However, if a woman has used hormone replacement therapy for many years, there is a possibility that she may have an excess of stored estrogen that can prevent fibroids from shrinking after menopause. A woman will almost never develop fibroid tumors when they are postmenopausal.
