Bleeding after menopause: is it normal, and why?

What is bleeding after menopause?

Menopause is recognized when you have gone 12 consecutive months without a period, with no other cause (WHO). Any vaginal bleeding after those 12 months is called postmenopausal bleeding. The amount doesn’t matter. Light spotting, a pink or brown mark on your underwear, or a single episode of bleeding all fall under this definition. The NHS recommends seeing a doctor even if the bleeding happened only once, is only spotting, or you’re not sure that what you saw is blood (NHS, Symptoms).

This is different from irregular bleeding in perimenopause. In perimenopause, periods become less frequent, and sometimes you skip a few months and then they return. Bleeding before the 12 months are up is generally not counted as postmenopausal bleeding. But the Turkish Ministry of Health’s Public Health Directorate (HSGM) advises that irregular bleeding before and after menopause should not be considered normal and that you should always see a doctor (HSGM). The NHS also recommends seeing a doctor if you still have periods but your bleeding has become noticeably heavier than before (NHS, Symptoms).

Why is bleeding after menopause taken seriously?

First, the reassuring part: the NHS says that bleeding after menopause is often not caused by anything serious. But the same source stresses that it can also be a sign of cancer, and that cancer can be easier to treat when it’s found early (NHS, Postmenopausal bleeding).

The numbers show this balance well. In a meta-analysis (a study that pools the results of many studies) combining a large number of studies:

• Endometrial cancer (cancer of the womb lining) was found in about 9 percent of women with postmenopausal bleeding. In other words, in the vast majority of those who had bleeding, the cause was not cancer.
• Among women with endometrial cancer, about 91 percent had had postmenopausal bleeding (Clarke et al., 2018).

So bleeding is usually not cancer, but endometrial cancer usually shows itself first through bleeding. The point of taking bleeding seriously is not to panic but to avoid missing this early sign.

What causes bleeding after menopause?

The NHS lists the causes of postmenopausal bleeding from most to least common as follows (NHS, Postmenopausal bleeding):

• Tissue thinning (atrophy): As estrogen falls, the inner lining of the vagina (atrophic vaginitis) or the womb lining (endometrial atrophy) becomes thinner and can become inflamed. This thin tissue can bleed easily. It is the most common cause.
• Polyps: Small growths, usually not cancer, that develop on the cervix or inside the womb.
• Thickening of the womb lining (endometrial hyperplasia): Hormone therapy, high estrogen levels or excess weight can cause this. It is not cancer itself, but it can progress to womb cancer over time, so it needs follow-up.

Less common causes include cancers such as womb cancer and ovarian cancer (NHS, Postmenopausal bleeding).

It isn’t possible to tell from symptoms which of these causes is involved. A painless, light, one-off bleed can come from a benign cause or from cancer. Only an examination and tests can tell them apart.

Where is the bleeding coming from?

When you see blood on your underwear or toilet paper after menopause, it may not always be clear where it’s coming from. Vaginal bleeding, blood in the urine and blood from the back passage can be confused with one another. You don’t have to work this out on your own. The NHS recommends seeing a doctor even if you’re not sure that what you saw is blood (NHS, Symptoms). It’s enough to tell your clinician exactly what you saw, when and in what circumstances you noticed it; the examination will make the distinction.

Which tests are done?

This section is for information; your clinician decides which tests are needed. According to the NHS, the following may be done (NHS, Postmenopausal bleeding):

• Physical examination: The doctor feels your abdomen and vagina to check for any lump, tenderness or swelling.
• Pelvic examination: An instrument called a speculum is used to look at the vaginal walls and the cervix.
• Vaginal ultrasound: A small probe placed in the vagina is used to image the uterus and ovaries. How the womb lining looks is an important part of this scan.
• Hysteroscopy and biopsy: A thin instrument with a camera on the end is passed through the cervix to look inside the uterus, and a small tissue sample (biopsy) is taken. The sample is examined in a laboratory. This can be done under local or general anesthesia.

Most of these tests are quick. If the results are normal, nothing more may be needed; if a cause is found, you’ll discuss the options with your clinician.

Which doctor should you see for bleeding after menopause, and how quickly?

When you notice bleeding, there’s no need to wait and think “I’ll go if it happens again.” Book an appointment soon. Even if the bleeding has stopped on its own, that does not remove the need for an assessment. And if your annual check-up is a few months away, don’t wait for that date; postmenopausal bleeding needs to be assessed separately, without waiting for a routine check-up. You don’t need to feel you’re wasting the doctor’s time just because the bleeding is light.

In the UK, the NHS expects a GP to refer the patient to a hospital or a postmenopausal bleeding clinic in this situation, with no more than a 2-week wait to see a specialist (NHS, Postmenopausal bleeding). This timeframe is a good measure of how seriously the situation is taken. In Türkiye, you can see your family doctor or go directly to an obstetrician-gynecologist. Saying “I’ve had bleeding after menopause” when you book makes the urgency clear.

While you wait for results

The days between the tests and the results can be anxious. That’s a completely natural reaction. During this time, it helps to keep the following in mind:

• In most people who have bleeding, the cause is not cancer; the purpose of the tests is to clarify the cause (Clarke et al., 2018; NHS, Postmenopausal bleeding).
• If the bleeding comes back or gets heavier, note it and tell your clinician.
• At the end of the appointment, ask when and how you’ll get the result, and whom you can call.
• Talk to your clinician before using any medication or vaginal product for the bleeding on your own.

Whatever the result, having gone early buys you time.

What should you note before the appointment?

Your clinician will most likely ask these questions; writing your answers down in advance makes things easier:

• When was your last period? If you don’t know the exact date, the approximate month and year is enough.
• When did the bleeding start, how many days did it last, how many times has it happened?
• How heavy was it: spotting, or bleeding that needed a pad?
• Did it happen during or after sex?
• Do you have other symptoms, such as pain, foul-smelling discharge or burning when you pee?
• Are you on hormone therapy, or what other medicines do you take?
