Bleeding After Menopause Menopause is officially reached once you've gone 12 months without a period.

So if you notice any bleeding or spotting after that point — even light, even just once — it's called postmenopausal bleeding.

And it should always be checked by your GP.

This isn't meant to alarm you. In most cases, the cause turns out to be straightforward and treatable. But because a small number of cases have a more serious cause, postmenopausal bleeding is never something to wait and watch.

Why Does Bleeding Happen After Menopause? There are several possible causes, and most are benign.

1. Vaginal and Womb Lining Changes (Atrophy)

With oestrogen settled at a much lower level, the tissue lining the vagina and womb becomes thinner and more fragile.

This can lead to:

▫️Light spotting

▫️Bleeding after sex

▫️Irritation or discomfort

This is the most common cause of postmenopausal bleeding.

1. Polyps

Small, usually non-cancerous growths can form in the womb lining or cervix.

They can cause irregular spotting or bleeding and are often simple to remove.

1. Hormone Replacement Therapy (HRT)

Some forms of HRT — particularly in the first few months of starting or changing a regimen — can cause breakthrough bleeding or spotting.

This is common but should still be mentioned to your GP, especially if it continues.

1. Infection or Inflammation

Infections of the vagina, cervix, or womb lining can occasionally cause bleeding.

1. Thickening of the Womb Lining

In some cases, the womb lining can thicken (endometrial hyperplasia), which needs to be assessed and, depending on the cause, treated.

1. Less Common: Endometrial Cancer

In a small percentage of cases, postmenopausal bleeding is caused by cancer of the womb lining.

This is exactly why every case is checked — catching it early makes treatment far more effective. Most women who are investigated do not have cancer, but investigation is the only way to know.

What Happens When You See Your GP Your GP will likely:

▫️Ask about your bleeding pattern, HRT use, and other symptoms

▫️Examine you, which may include a vaginal exam

▫️Refer you for a transvaginal ultrasound to check the thickness of your womb lining

▫️Possibly arrange a hysteroscopy or biopsy if the ultrasound findings need further investigation

This process is standard and most women are seen fairly quickly, precisely because postmenopausal bleeding is treated as a priority to check.

When to Seek Medical Advice Always contact your GP if you experience:

▫️Any bleeding or spotting after 12 months without a period

▫️Bleeding after sex

▫️Bleeding while on HRT that is heavy, prolonged, or doesn't settle

▫️Bleeding accompanied by pelvic pain

Don't wait for it to happen again, and don't assume it will resolve on its own. Get it checked the first time.

A Note on HRT-Related Bleeding If you're on cyclical HRT, a regular monthly bleed is expected and normal.

If you're on continuous combined HRT (no planned bleeding) and you experience breakthrough bleeding, this is common in the first 3–6 months but should be mentioned at your next review. Bleeding that starts after your periods on HRT had settled, or that continues beyond 6 months, should be checked sooner.

FAQ Section Is any bleeding after menopause normal?

No. Any bleeding after 12 months without a period should be checked by a GP, even if it's light or happens only once.

Does postmenopausal bleeding always mean something serious?

No. Most cases are caused by benign issues like vaginal thinning or polyps. But because a small number of cases have a more serious cause, it always needs investigating.

Can HRT cause bleeding?

Yes, particularly in the first few months of starting or changing HRT. It's still worth mentioning to your GP, especially if it persists.

How quickly should I see a doctor?

As soon as possible. Postmenopausal bleeding is generally treated as a priority referral, so most women are seen and investigated quickly.
