Postmenopausal bleeding is any vaginal bleeding that occurs after menstrual periods have stopped. While not always an emergency, it should be assessed to identify common benign causes and to rule out more serious conditions. Below are likely causes, typical investigations, and general follow‑up guidance.
Common causes at a glance
Causes range from benign to more serious. Frequent reasons include vaginal or endometrial atrophy (thinning of tissues), endometrial polyps, hormonal effects such as from hormone replacement, and medication‑related changes. Less commonly, endometrial hyperplasia or uterine cancer can be responsible. Bleeding can also come from clotting disorders, cervical lesions, or the urinary tract, so careful assessment is needed. The amount, timing and associated symptoms help guide priorities.
Typical tests and examinations
Evaluation usually begins with a detailed history and pelvic examination. Transvaginal ultrasound is commonly used to measure endometrial thickness. An endometrial biopsy (sampling tissue regardless of cycle) is often recommended when imaging or risk factors suggest it. Hysteroscopy allows direct inspection of the uterine cavity and can be combined with treatment when needed. Basic laboratory tests such as a full blood count and coagulation studies may be ordered to assess overall status. The choice of tests depends on the clinical context.
Risk factors and how they affect testing
Certain features increase the likelihood of significant pathology and influence the diagnostic approach: prolonged estrogen exposure, obesity, diabetes, high blood pressure, and a family history of gynecologic cancers. Recurrent or heavy bleeding, severe pain, and signs of anemia also raise priority. These factors help determine which investigations are done first and whether referral to a specialist is needed.
When to seek urgent care
Seek emergency evaluation if bleeding is extremely heavy and accompanied by fainting, dizziness, low blood pressure, shortness of breath, or very severe abdominal pain. High fever with bleeding or any sudden, rapidly worsening condition also warrants urgent assessment. If symptoms are milder, a scheduled appointment with a gynecologist is usually appropriate.
