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


    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.


    There are no specific steps to prevent this condition.
