Postmenopausal bleeding

Overview

Postmenopausal bleeding is any vaginal bleeding that occurs 12 months or more after your last menstrual period. It is not a normal part of menopause and should always be checked by a doctor.

Yes, postmenopausal bleeding is fairly common. About 10% of postmenopausal women will experience it at some point.

It affects women who have gone through menopause, usually those over age 45–55. It can also affect younger women who have had their ovaries removed or whose periods have stopped early due to medical treatments.

Symptoms

Common symptoms

• Any vaginal bleeding after more than 12 months without a period, including spotting or staining
• Light bleeding that may be pink, red, or brown
• Heavy bleeding that soaks through pads or tampons
• Bleeding after sex (postcoital bleeding)

Symptoms in older adults

• The same symptoms as common — any bleeding after menopause is abnormal

Causes

Main causes

• Thinning of the vaginal tissues (vaginal atrophy) — the most common cause
• Non-cancerous growths such as polyps or fibroids
• Endometrial hyperplasia (thickening of the womb lining)
• Endometrial cancer (cancer of the womb lining)
• Use of hormone replacement therapy (HRT), especially oestrogen-only HRT
• Cervical or vaginal infections

Risk factors

• Being overweight or obese
• Long-term use of oestrogen-only HRT
• Having diabetes or high blood pressure
• Never having been pregnant
• Starting menopause after age 55
• A family history of uterine or ovarian cancer

When to see a doctor

See a doctor urgently if:

• See your GP or gynaecologist as soon as possible if you have any vaginal bleeding after menopause, even if it stops on its own.
• If you have heavy bleeding with pain or dizziness, go to an emergency department.

Book a routine appointment if:

• If you are already under investigation for postmenopausal bleeding, follow your doctor's schedule for follow-up appointments.

Diagnosis

Your doctor will ask about your bleeding pattern, medical history, and any medications you take. They may then refer you to a gynaecologist for further tests.

Tests that may be done

• Transvaginal ultrasound — a small probe placed in the vagina to measure the thickness of the womb lining
• Endometrial biopsy — taking a small sample of the womb lining to check for abnormal cells
• Hysteroscopy — a thin telescope passed through the cervix to look inside the womb
• Blood tests to check for anaemia or hormone levels

What to expect at your appointment

You will likely be seen by a specialist in a gynaecology clinic. Many tests can be done in an outpatient setting and do not require an overnight stay. Your doctor will explain each test and what the results mean. You may need to wait a few weeks for results, but prompt investigation gives the best chance of a good outcome.

Treatment

Treatment depends on the underlying cause. Options range from simple monitoring to medication or surgery. Your doctor will discuss the best approach for you based on the test results and your overall health.

Self-care at home

• Keep a diary of any bleeding, noting dates, amount, and any pain.
• Avoid using tampons during bleeding episodes — use pads instead.
• Apply a cold pack to your lower belly if you have mild pain.
• Stay hydrated and eat iron-rich foods (like leafy greens and lean meat) if you are losing blood.

Medical treatments

If the cause is vaginal atrophy, your doctor may suggest vaginal moisturisers or topical oestrogen treatments (creams or rings) — these are applied locally and do not increase cancer risk significantly. For endometrial hyperplasia without cancer, progestogen (a hormone) can be given in various forms to help shed the lining. For fibroids or polyps, medication to shrink them or control bleeding may be offered. Treatment plans are individualised and may be adjusted over time.

When is surgery considered?

Surgery may be needed if the biopsy shows endometrial cancer, if large polyps or fibroids are causing problems, or if hyperplasia does not respond to medication. Options include removal of polyps or fibroids (hysteroscopic resection or myomectomy) or removal of the womb (hysterectomy). Your surgeon will explain the risks and benefits of each procedure.

Living with this condition

After treatment, you will need regular follow-up appointments to monitor for any recurrence of bleeding. Most women can return to normal activities within a few days to weeks, depending on the treatment. If you had surgery, follow your surgeon's advice about rest, lifting, and sexual activity.

Lifestyle tips

• Maintain a healthy weight to lower the risk of conditions linked to oestrogen.
• Stay physically active — aim for at least 30 minutes of moderate exercise most days.
• Avoid smoking and limit alcohol.
• Manage stress through relaxation techniques or hobbies you enjoy.

Diet and exercise

Eat a balanced diet rich in fruits, vegetables, whole grains, and lean protein. If you are anaemic from bleeding, include iron-rich foods such as spinach, beans, and fortified cereals. Gentle exercise, like walking or swimming, can help maintain bone health and overall wellbeing.

Mental health and emotional wellbeing

Worrying about postmenopausal bleeding can cause anxiety, stress, and fear of cancer. It is normal to feel this way. Talk to your doctor or a counsellor about your concerns. Support groups (online or in person) can connect you with others who have had similar experiences.

Prevention

Not all cases can be prevented, but you can lower your risk by maintaining a healthy weight, limiting the use of oestrogen-only HRT to the shortest possible time, and not smoking. Regular check-ups and prompt attention to any bleeding are the best ways to catch problems early.

Screening programmes

There is no routine screening test for postmenopausal bleeding, but if you are at higher risk (for example due to family history or obesity), your doctor may recommend regular pelvic exams or ultrasound. If you have any bleeding, you should be investigated regardless of screening.

Complications

If left untreated

• If the cause is cancer, it may spread (metastasize) to other parts of the body without treatment.
• Persistent bleeding can lead to anaemia (low red blood cells), causing fatigue, weakness, and shortness of breath.
• Non-cancerous conditions like fibroids or polyps can cause pain or heavy bleeding that interferes with daily life.

Long-term outlook

The outlook for postmenopausal bleeding is generally good, especially when you seek medical help promptly. Most causes are benign and easily treated. If cancer is found, early diagnosis greatly improves the chances of successful treatment and recovery. Even if the diagnosis is serious, modern treatments offer hope and support.
