Abnormal bleeding from the uterus that’s not related to menstruation is defined as uterine bleeding. Imperfect ovarian functioning is said to be the major reason for dysfunctional bleeding. Hormones and eggs that act on the uterus are usually provided by the ovaries.
A limited amount of blood is shed by a woman’s uterus in normal circumstances during every menstrual period. This is 80 ml or less than 5 tablespoons.Abnormal uterine bleeding is considered to be excessive menstrual bleeding or bleeding that occurs during menstrual periods. Any uterine bleeding will be termed as abnormal if the woman’s menstrual cycle has ended and she has entered menopause and is not taking any hormone therapy.
Different Causes of Bleeding From Uterus
Hormone secretion problems associated with the ovary are the cause of lack of menstrual bleeding. A physical examination is performed and medical history is taken by a doctor for diagnosing an ovulation.
It is also helpful to conduct blood tests for checking hormone levels. Medications are usually given for treatment as they can restore the balance of the hormones.
Abnormalities of the Cervix and Vagina
Bleeding can also be caused by infections or other conditions of the vagina and cervix. The bleeding can also be associated with intercourse because it is usually light. Light bleeding may also occur in postmenopausal women because their vagina walls become thin. Bleeding can also be caused due to abnormalities of the cervix such as cervical cancer. Office tests and a physical examination is helpful for diagnosing these conditions.
Benign and noncancerous growths that develop in the uterus are called fibroids. No symptoms occur in most women who suffer from fibroids and they may not need treatment. Medical attention should be sought in case any symptoms occur.
Irregular uterine bleeding can also occur because of these benign growths in the uterine lining. A hysteroscopy is a procedure used for removing these growths. A slender telescope is inserted into the uterine cavity of the women through the vagina and the cervix in this procedure for the purpose of examining the cavity and removing the polyps.
Cancer of the lining of the uterus or endometrial cancer is usually indicated by abnormal bleeding in women who have already experienced menopause.
Tests in the office such as endometrial biopsy can be used for diagnosing this problem. The endometrius is cleaned from some of the cells in this procedure. If diagnosed early, surgery can also treat endometrial cancer.
Hypothalamus might be affected by psychological disturbances or emotional stress and can lead to uterine bleeding because it suppresses stimulants to the ovary. Anxieties, chronic illnesses, sexual problems, changes in environment and obesity can also cause dysfunctional bleeding.
Heart congestion, clotting defects, anemia and fragile capillaries are some cardiovascular and blood disorders that contribute to abnormal bleeding. If the blood pressure is high, small blood vessels may rupture.
The uterine wall can also be injured or bruised by local injuries. Irritation and injury can also be caused by mechanical contraceptive devices, abortion attempts, intercourse, forceful inserting of tampons and masturbation.
