What causes dysfunctional uterine bleeding?

Dysfunctional uterine bleeding (DUB) is caused by abnormal levels of the hormone estrogen. In women with normal periods, the high level of estrogen decreases after releasing an egg. With dysfunctional uterine bleeding, the egg is not always released and the woman's uterine lining sheds irregularly. Other causes of hormone imbalance, including thyroid problems and some medication, can also cause DUB.

Hormone imbalance is a common cause of dysfunctional uterine bleeding.

Thyroid conditions, weight fluctuations and hormones secreted by the pituitary gland can all affect the menstrual cycle. If dysfunctional uterine bleeding (DUB) occurs, medical care should be sought. Individuals over the age of 40 often require endometrial tissue biopsy to exclude pathologic conditions.
