Your uterine bleeding may be heavy. Or you may have bleeding between periods. They may be caused by an imbalance of hormones. Or they can be caused by growths, an intrauterine device (IUD), bleeding disorder, or pregnancy. Learn more about the causes below.
Hormonal imbalance
Your menstrual cycle is controlled by hormones. They include estrogen and progesterone. Sometimes there is too much or too little of one or both of these hormones. This can cause heavy periods. Or it can cause bleeding between periods. Causes of hormonal imbalance can include:
- Hormonal changes in teens and in people nearing menopause.
- Diabetes, thyroid disease, or other medical problems.
- Obesity.
- Stress.
- Heavy exercise.
- Anorexia, an eating disorder.
- Pregnancy.
Uterine growths
There are different kinds of uterine growths. These include:
Fibroids. These are round knots of muscle tissue in the uterus. They are not cancer (benign).
Polyps. These are soft tissue growths in the uterine lining. They often extend into the uterus.
Adenomyosis. This is when the uterine lining grows into the muscle wall.
Hyperplasia. This is when the uterine lining gets too thick or grows too much.
Endometrial cancer. This is uncontrolled growth of abnormal cells in the uterine lining.
Other causes of uterine bleeding
There are other causes of uterine bleeding. They include:
- IUD (intrauterine device). This is a method of birth control. Some IUDs contain hormones.
- Bleeding disorders. This is when the blood can't clot normally.
- Uterine or cervical cancer. This is cancer of the uterus or cervix.
