  • Uterine fibroid
  • Bleeding disorder (eg, von Willebrand disease )
  • Hormonal imbalance
  • Cervical or endometrial polyp
  • Ovarian cyst
  • Certain medicines
  • Intrauterine device (IUD)
  • Risk Factors

    Factors that may increase the risk of menorrhagia include:

        
  • Being an adolescent
  • Approaching menopause
  • Symptoms

    Symptoms of menorrhagia include:

        
  • Menstrual bleeding lasting more than seven days
  • Unusually heavy bleeding (soaking through a sanitary napkin or tampon every hour)
  • Menstrual flow requiring change of sanitary protection during the night
  • Menstrual flow including large clots
  • Menstrual flow interfering with lifestyle
  • Fatigue and/or shortness of breath (symptoms of anemia )
  • When Should I Call My Doctor?

    Call your doctor if you have symptoms of menorrhagia.

    Diagnosis

    Your doctor will ask about your symptoms and medical history. A physical examination, including a pelvic exam, will be done. Tests may include:

        
  • Pap test
  • Blood tests
  • Transvaginal ultrasound
  • Endometrial biopsy (removal of a sample of endometrial tissue)
  • Dilation and curettage (scraping of the inner lining of the uterus)
  • Hysteroscopy (examination of the cervix and fallopian tubes)
  • Treatment

    Treatment depends on the underlying cause of the heavy menstrual bleeding. Your doctor will work with you to create a treatment plan.

    Medications

    Your doctor may recommend:

        
  • Hormonal therapy
  • An IUD that releases the hormone progesterone
  • Nonsteroidal anti-inflammatory drugs
  • Iron supplement
  • Surgical Procedures

    In some cases, surgery may be needed, such as:

        
  • Dilation and curettage
  • Operative hysteroscopy (may be used along with other tools to remove a polyp)
  • Endometrial ablation (removal of the lining of the uterus)—This procedure reduces your chance of becoming pregnant.
  • Hysterectomy (removal of the uterus)—After this procedure, you will not be able to become pregnant.
  • Prevention

    There are no specific steps to prevent this condition.
