- Infection of the uterus or cervix
- Fibroids or polyps
- Problems with blood clotting

How is abnormal uterine bleeding diagnosed?
Diagnosing the cause of abnormal uterine bleeding starts with a complete medical history, including detailed information on your normal menstrual cycle and the abnormal bleeding you are experiencing. Keep a record of the dates, duration, and amount of abnormal bleeding.
A physical exam, pelvic exam, and Pap smear should also be conducted.
Additional tests may include:
- Screening for STDs (sexually transmitted diseases)
- Blood tests
- Ultrasound. To take images of your pelvic organs.
- Endometrial biopsy. To obtain and analyze a tissue sample from the lining of your uterus.
- Sonohysterography. An ultrasound using sterile saline to expand the uterine cavity for easier imaging.
- Hysteroscopy. An office procedure using a small, lighted telescope (hysteroscope) inserted through the vagina and cervix to see the inside of the uterus.
- Hysterosalpingography. An x-ray taken after injecting dye into the uterus and fallopian tubes.
- Dilation and curettage (D&C). To obtain tissue from the lining of the uterus for examination under a microscope.
- Laparoscopy. A thin, lighted tube with a camera on the end (laparoscope) is inserted into the abdomen through a small incision, allowing the surgeon to see inside the abdomen.
How is abnormal uterine bleeding treated?
Treatment of abnormal uterine bleeding depends on the cause, patient's age and other factors. Treatment options include:
- Wait and watch approach
- Medical treatment. Using hormones such as oral contraceptives, estrogen and progestins, and other medications.
- Surgical treatment. To remove growths such as polyps or fibroids that can cause bleeding. Surgery can often be performed using hysteroscopy, a minimally invasive approach to examine and treat areas of concern inside the uterus.
