Postmenopausal Bleeding

Postmenopausal bleeding (PMB) refers to any vaginal bleeding that occurs after menopause, which is defined as the time when a woman has not had a menstrual period for 12 consecutive months.

Causes of Postmenopausal Bleeding

• Hormone replacement therapy (HRT): HRT can cause PMB in some women, especially during the first year of treatment.
• Endometrial atrophy: Thinning of the lining of the uterus (endometrium) is a common cause of PMB.
• Endometrial polyps: Growths in the lining of the uterus can cause bleeding.
• Uterine fibroids: Non-cancerous growths in the uterus can cause bleeding.
• Endometrial hyperplasia: Thickening of the lining of the uterus can cause bleeding.
• Endometrial cancer: Cancer of the lining of the uterus is a rare but serious cause of PMB.
• Cervical polyps: Growths on the cervix can cause bleeding.
• Cervical cancer: Cancer of the cervix is a rare cause of PMB.
• Vaginal atrophy: Thinning and drying of the vaginal walls can cause bleeding.
• Other medical conditions: Certain medical conditions, such as thyroid disorders or liver disease, can cause PMB.

Risk Factors for Postmenopausal Bleeding

• Age: The risk of PMB increases with age.
• Family history of endometrial cancer or other gynecologic cancers: Women with a family history of these cancers are at increased risk of developing PMB.
• Obesity: Obesity is associated with an increased risk of PMB.
• Hormone replacement therapy (HRT): HRT can increase the risk of PMB.
• Tamoxifen use: Tamoxifen, a medication used to treat breast cancer, can increase the risk of PMB.

Diagnosis and Evaluation of Postmenopausal Bleeding

A thorough medical history, physical examination, and diagnostic tests are necessary to determine the cause of PMB. Diagnostic tests may include:

• Pelvic exam: A pelvic exam is performed to check for any abnormalities in the uterus, cervix, or vagina.
• Transvaginal ultrasound (TVUS): TVUS uses sound waves to create images of the uterus and ovaries.
• Endometrial biopsy: A sample of tissue is taken from the lining of the uterus to check for cancer or other abnormalities.
• Pap test: A Pap test is performed to check for abnormal cells on the cervix.
• Other diagnostic tests: Other tests, such as a hysteroscopy or dilation and curettage (D&C), may be necessary to determine the cause of PMB.

Treatment and Management of Postmenopausal Bleeding

Treatment for PMB depends on the underlying cause. Treatment options may include:

• Hormone replacement therapy (HRT): HRT may be prescribed to manage symptoms of menopause, including PMB.
• Progesterone therapy: Progesterone therapy may be prescribed to thin the lining of the uterus and reduce bleeding.
• Endometrial ablation: A procedure that destroys the lining of the uterus to reduce or stop bleeding.
• Hysterectomy: Surgical removal of the uterus may be necessary in some cases, such as endometrial cancer.
• Other treatments: Other treatments, such as medications or lifestyle changes, may be recommended to manage symptoms and underlying conditions.
