Bleeding after menopause

If you experience vaginal bleeding after menopause, even if it is light or happens only once, you should arrange an assessment with a gynaecologist. In many cases the cause is benign and treatable. The purpose of the assessment is to identify the cause and safely rule out more serious conditions.

What is postmenopausal bleeding?

Postmenopausal bleeding is any vaginal bleeding that occurs after 12 consecutive months without a menstrual period. Menopause is defined retrospectively after this year without periods, so bleeding afterwards should not be assumed to be a returning menstrual cycle. It may appear as spotting, pink or brown discharge, or heavier bleeding.

The amount of blood does not indicate how serious the cause is. Even a small amount of spotting deserves assessment. If you are unsure whether you have reached menopause, discuss the bleeding with a healthcare professional.

Why does it need to be checked?

Most cases have a benign explanation, such as thinning of the vaginal or uterine lining. However, bleeding after menopause is also the most common warning symptom of endometrial (womb) cancer. This does not mean that cancer is the likely diagnosis, but it is important to investigate rather than wait for the bleeding to recur.

Possible causes

• Vaginal or endometrial atrophy: lower oestrogen levels make the vaginal and uterine lining thinner and more fragile.
• Endometrial or cervical polyps: usually benign growths that can cause intermittent bleeding.
• Endometrial hyperplasia: thickening of the uterine lining, sometimes associated with hormonal factors.
• Medication: hormone therapy or blood-thinning medicines may contribute to bleeding, although they do not remove the need for assessment.
• Endometrial cancer or other less common conditions: these need to be ruled out when appropriate.

How is it investigated?

Your gynaecologist will ask about the bleeding, menopause, medication and medical history, and may perform a pelvic examination. A transvaginal ultrasound scan is commonly the first imaging test. It assesses the thickness and appearance of the endometrium and may identify polyps or other abnormalities.

Depending on the ultrasound findings and your risk factors, further tests may be recommended, such as an endometrial biopsy or hysteroscopy. Hysteroscopy allows the inside of the uterus to be examined with a fine camera and, when needed, a targeted sample to be taken.

What happens next?

Management depends on the cause. Atrophy may be treated with appropriate local therapy; polyps can often be removed hysteroscopically; and endometrial hyperplasia requires follow-up and treatment tailored to the biopsy result. If a more serious condition is suspected or diagnosed, your clinician will explain the next steps and arrange appropriate specialist care.

When should you seek medical advice?

Any bleeding after menopause should be assessed, even if it is a single episode or only spotting. Seek urgent care if bleeding is heavy, you feel faint or unwell, or you have severe pain.

Frequently asked questions

Is bleeding after menopause ever normal?

It is not considered a normal period. Although the cause is often benign, every episode should be assessed by a healthcare professional.

Does a small amount of spotting need checking?

Yes. The amount or colour of the blood cannot reliably identify the cause, so even light spotting should be assessed.

Will I need a biopsy?

Not always. The need for a biopsy or hysteroscopy depends on the ultrasound findings, your medical history and other risk factors.
