Uterine fibroids – Myoma
The uterus is part of a female reproductive organ located between the bladder and the rectum. The main purpose of the uterus is to nourish a fetus until birth. If the egg does not become fertilized by the time it reaches the uterus, it is reabsorbed and shed along with the peeled lining of the uterus through the cervix, into the vagina and out of the body. This is called menstruation.
The uterus has three layers:
- Endometrium (the inner lining)
- Myometrium (the middle muscular layer)
- Perimetrium (the outer layer)
Uterine fibroids are very common non-cancerous (benign) tumors that are formed in the muscular wall of the uterus (Myometrium). It affects more than 30% of women after the age of 30. Fibroids can grow as a single tumor, or there can be many of them inside or outside the uterus. They can range in size from very tiny to larger than a grapefruit. Uterine fibroids may be related to estrogen hormone that is produced in the ovaries. Uterine fibroids during pregnancy may cause abortion, early labor, early separation of the placenta and heavy uterine bleeding after childbirth.
There are 3 types of uterine fibroids:
- Intramural: Which is the most common type. This type of fibroid grows and develops on the wall of the uterus, and presses on the lining of the uterus causing an increase in menstrual bleeding and duration. However, this type of fibroid often does not affect fertility.
- Submucosal: This type of fibroid grows under the lining of the uterus inside the uterine cavity and causes long duration of the menstrual cycle and increases bleeding and pain. Thus, this type of fibroid often affects fertility and increases the frequency of miscarriages.
- Subderosal: This type of fibroid grows from the uterus towards the abdominal cavity and causes pressure on nearby organs such as bladder and rectum. This pressure can cause frequent urination and / or constipation.
