Bleeding after menopause: causes, tests and treatment — Dr Jérémie Zeitoun Paris
Gynaecology · Patient guide

Bleeding after menopause: which causes, which tests?

Bleeding that occurs after menopause is never "normal" — however light, even a single episode. The great majority of these bleeds have a benign cause — atrophy, a polyp, hyperplasia of the endometrium. But because they can also be the first sign of endometrial cancer, any postmenopausal bleeding deserves a work-up, without delay and without alarm: consulting early gives you every chance of a straightforward diagnosis.

Bleeding after menopause, even light?
A prompt consultation, a full work-up, a clear answer.

Whether the bleeding is isolated or repeated, whether your ultrasound shows a thickened endometrium or a polyp — Dr Zeitoun organises the work-up (ultrasound, biopsy, hysteroscopy) and, where needed, the surgical treatment, from diagnosis to follow-up.

No medical advice can be given without an in-person consultation and a full review of your file.

Menopause is defined by twelve consecutive months without periods. Past that point, the endometrium — the lining of the inside of the uterus — is no longer stimulated by ovarian hormones: it thins out and no longer bleeds. Any bleeding that reappears afterwards, whether red blood, pink or brownish discharge, is therefore a signal that warrants investigation.

That signal is most often reassuring in the end: in the great majority of cases, the work-up finds a benign cause — atrophy of the lining, an endometrial polyp, a cervical polyp, or hyperplasia of the endometrium. More rarely, it reveals endometrial cancer — a cancer whose first sign is precisely bleeding, and which, detected early, is treated with a good prognosis. That is the whole point of consulting promptly.

This article explains why you should consult even for a single trace of blood, what the possible causes are, how the work-up unfolds — transvaginal ultrasound then hysteroscopy, which is at the heart of diagnosis and treatment — and in which situations a hysterectomy becomes necessary. It draws on the guidelines of the CNGOF and the French National Cancer Institute.

Bleeding after menopause should not be waited out — it should be investigated.

THE RIGHT REFLEX

Why consult, even for a single trace of blood

There is no organised screening for endometrial cancer. Bleeding is the warning signal that takes its place: it is what makes early diagnosis possible. And the first reflex, faced with this bleeding, is always to rule out a cause lower down — in the cervix, vagina or vulva — before exploring the uterus.

Gynaecological consultation for bleeding after menopause — Dr Jérémie Zeitoun Paris
The principle

After menopause, the uterus no longer bleeds

Twelve months without periods marks menopause: the endometrium, deprived of hormonal stimulation, becomes thin and no longer sheds. Any subsequent bleeding is therefore abnormal by definition — whatever its volume, colour or duration.

This applies to red blood as well as to pink or brownish discharge, to a single episode as well as to repeated bleeding, and whether your menopause dates back two years or twenty. The instruction is the same: consult — not as an emergency, but without delay.

Four figures to keep in mind

Most Benign causes The great majority of postmenopausal bleeds have a benign cause.
12 months No periods = menopause Beyond 12 months without periods, any bleeding is abnormal and deserves a work-up.
≤ 4 mm Reassuring endometrium Endometrial thickness on ultrasound making cancer very unlikely (off hormone therapy).
Early = good prognosis When cancer is involved, early diagnosis allows simple, effective treatment.

Key point: consulting for postmenopausal bleeding is not worrying for nothing — it is doing exactly what medicine expects of this symptom. Most of the time you leave reassured; and if not, you will have made an early diagnosis possible, at the stage where treatment is simplest and most effective.

UNDERSTANDING

The possible causes, the reflex first

Bleeding after menopause may come from the uterus, but also from the cervix, vagina or vulva. The reflex is therefore always to rule out a lower cause through clinical examination, before exploring the endometrium.

Cervix, vagina, vulva

First of all, the clinical examination looks for a cause lower down: a lesion of the cervix (including a polyp), the vagina or the vulva. Speculum, smear if needed and vulvar inspection are the first, systematic step of the work-up.

Clinical examFirst step

Atrophy of the endometrium and vagina

Deprived of oestrogen, the lining becomes thin and fragile: it can bleed spontaneously or after intercourse. It is the leading cause of postmenopausal bleeding — benign, but accepted only once everything else has been ruled out.

BenignDiagnosis of exclusion

Polyp of the endometrium or cervix

A benign outgrowth of the lining, an endometrial polyp or cervical polyp tends to bleed intermittently. After menopause, its removal by hysteroscopy and analysis are systematically recommended.

HysteroscopySystematic analysis

Endometrial hyperplasia

A thickening of the uterine lining, often the source of the bleeding. It is diagnosed and treated by operative hysteroscopy, with endometrectomy (resection of the lining), which both stops the bleeding and provides the tissue for analysis.

Operative hysteroscopyEndometrectomy

Endometrial cancer

Rarer, but it is what the work-up sets out to rule out first, because its first sign is precisely bleeding — and its prognosis depends greatly on how early it is diagnosed. Learn more.

To rule outEarly diagnosis

Bleeding on treatment

Tamoxifen can stimulate the endometrium and promote polyps and thickening; an anticoagulant can amplify bleeding without creating its cause. Neither removes the need for a work-up: on the contrary, they may reveal an underlying lesion.

TamoxifenWork-up regardless

Risk factors for endometrial cancer worth knowing: age, overweight and obesity (fatty tissue produces oestrogen), diabetes, high blood pressure, tamoxifen, and Lynch syndrome (a hereditary predisposition warranting genetic counselling). Having these factors does not mean having cancer — but they make it all the more important never to dismiss bleeding.

THE WORK-UP

The tests: ultrasound and hysteroscopy

The work-up follows a simple logic: examine (cervix, vagina, vulva), look (ultrasound), then explore the uterine cavity by hysteroscopy when needed. Hysteroscopy is the central examination: it makes it possible to see, sample and treat all at once.

Transvaginal pelvic ultrasound measuring endometrial thickness — Dr Jérémie Zeitoun
First step

Transvaginal ultrasound: measuring the endometrium

Performed vaginally and painless, it measures the thickness of the endometrium and looks for a polyp, a fibroid or an ovarian abnormality. In a postmenopausal woman not on hormone therapy, an endometrium of ≤ 4 mm makes cancer very unlikely.

A thickened or heterogeneous endometrium, a polyp, or bleeding that persists or recurs despite a reassuring ultrasound: in these situations, we move on to hysteroscopy to see the cavity directly and treat in the same session.

01

Full clinical examination

Speculum examination (cervix, vagina), pelvic examination, vulvar inspection — to rule out first a lower cause and miss nothing downstream of the uterus.

02

Transvaginal ultrasound

Painless, it measures the thickness of the endometrium and spots polyps, fibroids or ovarian abnormalities. It is what guides the rest of the work-up.

03

Hysteroscopy: see, sample, treat

A fine camera introduced through the natural routes visualises the whole uterine cavity, and in the same session allows a polyp to be removed or the lining to be resected (endometrectomy), with analysis of the tissue removed. Hysteroscopy in detail.

In practice at the clinic: Dr Zeitoun performs the clinical examination and the ultrasound from the very first consultation, and organises the rest of the work-up. Hysteroscopy, diagnostic then operative, is scheduled as day surgery at Clinique Hartmann: it is what allows, in a single procedure, to see, remove the lesion and analyse it. The results are explained to you at a dedicated consultation.

DIAGNOSIS AND TREATMENT IN ONE STEP

Endometrial hyperplasia: operative hysteroscopy

"Hyperplasia" means the uterine lining has thickened. It is a frequent cause of bleeding after menopause — and operative hysteroscopy allows it, in the same procedure, to be diagnosed and treated.

Operative hysteroscopy + endometrectomy

Through the natural routes, with no scar, the camera explores the uterine cavity and the endometrectomy removes the thickened lining. The procedure stops the bleeding and provides the whole tissue for analysis — far more representative than a simple sample. Hysteroscopy in detail.

Natural routesDay surgery

The analysis decides what comes next

The tissue removed is analysed under the microscope. In the great majority of cases, hysteroscopy has solved the problem. Only in the event of atypical hyperplasia or cancer on analysis — or failure / recurrence of bleeding — is a hysterectomy discussed.

HistopathologyTailored decision

The pathway, simple and stepwise: we begin with hysteroscopy, which sees and treats. It is enough in the great majority of situations. A hysterectomy only comes into play in specific cases: failure or recurrence of bleeding, a diagnosis of atypical hyperplasia, or endometrial cancer. We only move up a step when it is genuinely necessary.

THE NEXT STEP, WHEN IT IS NEEDED

When a hysterectomy becomes necessary

In most cases, hysteroscopy has solved the problem. A hysterectomy is only considered in three situations: bleeding that persists or recurs despite hysteroscopy, atypical hyperplasia, or endometrial cancer.

Laparoscopic hysterectomy in the operating theatre — minimally invasive surgery, Dr Jérémie Zeitoun Clinique Hartmann
The technique

A laparoscopy, minimally invasive

When indicated, a hysterectomy is most often performed laparoscopically (a few short incisions, a camera and fine instruments): simpler recovery, less pain, a short hospital stay — usually 1 to 3 nights — and a faster return to activity than with open surgery.

Depending on the situation, it removes the uterus alone or together with the ovaries and tubes. The detail of the operation, its recovery and its variants is explained on the dedicated page: hysterectomy.

And if it is endometrial cancer? Caught early thanks to the bleeding, it most often carries a good prognosis and relies first on surgery. The work-up, the stages and the full range of treatments are detailed on the dedicated page: endometrial cancer. Dr Zeitoun manages this pathway and also sees patients for a second opinion.

YOUR QUESTIONS

Frequently asked questions

Is bleeding after menopause always serious?

No. In the great majority of cases, the cause is benign: endometrial atrophy, a polyp, hyperplasia of the endometrium. But because bleeding can also be the first sign of endometrial cancer, any bleeding must be investigated, without exception.

I had a single, light episode of bleeding: do I really need to see a doctor?

Yes. Even a single, light, pink or brownish episode warrants a consultation. When endometrial cancer is involved, it is almost always bleeding that reveals it, often discreetly at first. Consulting early makes a diagnosis at an early stage possible, when treatment is simpler.

What are the possible causes?

The most frequent are benign: atrophy of the endometrium or vagina, a polyp of the endometrium or cervix, endometrial hyperplasia, bleeding promoted by tamoxifen or an anticoagulant. More rarely it is an endometrial cancer, or a cause of the cervix, vagina or vulva — which the clinical examination rules out first.

What is the risk that it is cancer?

The great majority of bleeds after menopause are benign. The risk of cancer exists but remains a minority; it increases with age and certain factors (overweight, diabetes, tamoxifen, Lynch syndrome). Only investigation can rule out a serious cause with certainty — hence the importance of consulting.

Which tests will I have?

The work-up combines a full gynaecological examination, a transvaginal pelvic ultrasound measuring the thickness of the endometrium, and if needed a tissue sample: an endometrial biopsy in the consulting room or a hysteroscopy, which visualises the inside of the uterine cavity and allows a lesion to be sampled or removed.

What does endometrial thickness on ultrasound mean?

After menopause, the endometrium is normally thin. A thickness of 4 mm or less in a woman not taking hormone therapy makes cancer very unlikely. Above that, or if the bleeding persists despite a reassuring ultrasound, a tissue sample is needed: the image does not replace microscopic analysis.

Does an endometrial biopsy hurt?

It is performed in the consulting room, without anaesthesia, using a thin flexible tube (pipelle) introduced through the cervix. It most often causes a brief cramp, comparable to period pain, which settles within a few minutes. Light bleeding may follow for a day or two.

What is endometrial hyperplasia?

It is a thickening of the uterine lining, a frequent cause of bleeding. It is diagnosed and treated by operative hysteroscopy, with endometrectomy (resection of the lining), which stops the bleeding and provides the tissue for analysis. Only in case of atypical hyperplasia on analysis is a hysterectomy then discussed.

What happens if endometrial cancer is found?

Caught early thanks to the bleeding, the cancer most often carries a good prognosis and relies first on surgery (hysterectomy). The work-up, the stages and the full range of treatments are detailed on the dedicated page on endometrial cancer. Dr Zeitoun manages this pathway and also sees patients for a second opinion.

I take menopausal hormone therapy: is bleeding normal?

Some HRT regimens cause scheduled bleeding, and light bleeding can occur in the first months. However, any unexpected or persistent bleeding, or bleeding after a long bleed-free interval, must be investigated as in any postmenopausal woman.

I am on anticoagulants: could that explain my bleeding?

An anticoagulant can trigger or amplify bleeding, but it does not create the lesion that bleeds. It sometimes reveals a polyp, hyperplasia or a cancer that would otherwise have remained silent. Anticoagulant treatment therefore never removes the need for the usual work-up.

Are the consultation and surgery covered?

The investigation of postmenopausal bleeding and its treatment, including surgery, are covered by the French national health insurance. I charge supplementary fees (sector 2, non-OPTAM), explained during the consultation and set out in a written quote provided before any procedure.
