    Study Notes

    Diagnostic Evaluation for Menorrhagia

    • History collection
    • Physical examination
    • Blood tests
      • To determine levels of hormones produced by the pituitary gland (FSH, LH, TSH and prolactin) and the ovaries (estrogen)
    • Ultrasonography of the pelvis
      • To assess abnormalities of the genital tract or look for polycystic ovaries.
    • CT Scan or MRI of the head
      • To exclude pituitary and hypothalamic causes of amenorrhea.

    Additional Tests for Menorrhagia

    • Determination of prolactin levels
    • Hysterosalpingogram (x-ray test)
      • To examine the uterus
    • Hysteroscopy
      • To examine the endometrium, which is shed during menstruation.

    Menorrhagia Causes

    • Hormone imbalance
      • The endometrium develops in excess and eventually sheds via heavy menstrual bleeding.
    • Dysfunction of the ovaries
      • Ovaries may not release an egg (ovulate) during a menstrual cycle (anovulation). This can lead to hormone imbalance.
    • Uterine fibroids
      • Noncancerous tumors of the uterus that can cause heavier than normal or prolonged menstrual bleeding.
    • Polyps
      • Small, benign growths on the lining of the uterus (uterine polyps) that can cause heavy or prolonged menstrual bleeding.
    • Adenomyosis
      • Glands from the endometrium become embedded in the uterine muscle, often causing heavy bleeding and painful menses.
    • Intrauterine device (IUD)
      • A common side effect is menorrhagia, which may require removal of the IUD.
    • Pregnancy complications
      • Heavy bleeding can be due to a miscarriage.
    • Cancer
      • In rare cases, uterine, ovarian, and cervical cancer can cause excessive menstrual bleeding.

    Clinical Manifestations of Menorrhagia

    • Soaking through one or more sanitary pads or tampons every hour for several consecutive hours.
    • Needing to use double sanitary protection to control menstrual flow.
    • Needing to wake up to change sanitary protection during the night.
    • Bleeding for longer than a week.
    • Passing blood clots with menstrual flow for more than one day.
    • Restricting daily activities due to heavy menstrual flow.
    • Symptoms of anemia, such as tiredness, fatigue or shortness of breath.

    Diagnostic Evaluation for Menorrhagia

    • History collection
    • Physical examination
    • Blood test
      • To check for iron deficiency (anemia) and other conditions, such as thyroid disorders or blood-clotting abnormalities.
    • Pap test
      • To test for infection, inflammation, or changes that may be cancerous or lead to cancer.
    • Endometrial biopsy
      • To examine tissue from the lining of the uterus.
    • Ultrasound scan
      • To produce images of the uterus, ovaries, and pelvis.
    • Sonohysterogram
      • A fluid is injected into the uterus to look for problems in the lining.
    • Hysteroscopy
      • This procedure examines the cervix and the lining of the uterus.

    Treatment Options for Menorrhagia

    • Hormonal therapy
      • Birth control pills, progestin-only pills, or other hormone medications can help regulate the menstrual cycle.
    • Nonsteroidal anti-inflammatory drugs
      • These drugs can help reduce pain and inflammation.
    • Iron supplements
      • To treat anemia.
    • Dilation and curettage (D&C)
      • This procedure widens the cervix and then scrapes or suctions tissue from the lining of the uterus to reduce menstrual bleeding.
    • Uterine artery embolization
      • This procedure shrinks fibroids by blocking blood flow to them.
