Fibroids are abnormal growth of tissues that develop in the woman’s uterus. The growths are typically benign or non-cancerous. In some cases, they cause no signs or symptoms at all. But sometimes fibroids become quite large and cause severe abdominal pain and heavy periods. The root cause of fibroids is still unknown to medical science.
Intramural fibroids are one of the most common types of fibroids. 70% of the women develop these fibroids in their childbearing age. Intramural fibroids develop within the wall of the uterus. They begin as a small nodules in the muscular wall of the uterus. Intramural fibroids may develop inwards, which will lead to distortion and elongation of the uterine cavity.
These fibroids can grow towards the endometrial cavity to become submucosal fibroids. They can also grow towards the outer surface of the uterus to become subserosal fibroids.
Symptoms of Intramural Fibroids
Intramural fibroids often cause few, if any, symptoms. But it may cause you to experience severe discomfort. Its symptoms are similar to those of other fibroids types. Some of the common symptoms of Intramural fibroids are:
- Heavy menstrual bleeding
- Prolonged menstrual periods
- Pelvic pain
- Bleeding between menstrual periods
- Lower back pain
- Frequent urination
Causes of Intramural Fibroids
Exact cause of intramural fibroids is still unknown. But there are some factor which can contribute to its development. Estrogen and progesterone hormones are major reason behind the development of intramural fibroids. These hormones are produced in the ovaries.
Women who have family history of fibroids are more prone towards developing fibroids. Also during the pregnancy, estrogen and progesterone hormones are produced rapidly and may lead to the development of fibroids. African American women at more risk of intramural fibroids.
Intramural Fibroids and Pregnancy
It has been observed that only 3% of women with these fibroids are linked with infertility. In case intramural fibroids get enlarged or multiple fibroids are developed, then a women may find conceiving troublesome.
If intramural fibroids are located at the cervix, it can prevent sperm from entering the uterine cavity. These fibroids can also enlarge the cavity of the uterine, which will increase the distance that sperms need to travel to reach the fallopian tube. Also, intramural fibroids can affect the uterus ability to contract, which will affect sperm migration and ovum transport.
Intramural fibroids may also inhibit the implantation of the embryo. They can distort the uterine cavity, affecting the blood supply to the endometrium and interfering with endometrium structure. Even after successful implantation, these fibroids may interfere with the development of the fetus.
Fibroids gets larger as the pregnancy proceeds, this starts a struggle for space between the fetus and the intramural fibroids. This could induce defects in the unborn baby or may even lead to miscarriage.
