Endometrial Ablation

Introduction

If you have been living with heavy menstrual bleeding that soaks through pads or tampons, disrupts your sleep, leaves you tired from low iron, or simply keeps you from your daily life, you are not alone. Heavy periods are one of the most common reasons women see a gynaecologist, and for many, medications or hormonal devices bring enough relief. For others, they do not — and that is often the point at which a doctor brings up endometrial ablation.

Endometrial ablation is a short, minimally invasive procedure that removes or destroys the lining of the uterus (the endometrium) so that periods become much lighter or stop altogether. It is not a hysterectomy. The uterus stays in place. There are no cuts on the abdomen. Most women go home the same day and return to normal activities within about a week.

This article is written for women who have been told ablation may be an option, or who are weighing it against alternatives such as a hormonal IUD or hysterectomy. It explains what the procedure is, who it suits, the different techniques used, what to expect on the day, recovery, risks, and what life tends to look like afterwards.

What Is Endometrial Ablation?

The inside of the uterus is lined with a layer of tissue called the endometrium. Each month, hormones cause this lining to thicken and then shed as a menstrual period. When the lining is unusually thick, when hormone levels are imbalanced, or when conditions such as fibroids or adenomyosis affect the uterus, periods can become very heavy or prolonged.

Endometrial ablation is a procedure that deliberately destroys most of this lining. Once the lining is gone, much less tissue grows back each month, so bleeding is significantly reduced or stops altogether. The procedure is done through the vagina and cervix — there are no external incisions. It typically takes between 5 and 30 minutes depending on the technique used.

An important point to understand from the start: endometrial ablation is not a form of contraception, and it is not designed for women who may want a future pregnancy. Although fertility is significantly reduced after ablation, pregnancy can still occur, and a pregnancy after ablation carries serious risks. Reliable contraception remains necessary until menopause.

Why Is Endometrial Ablation Performed?

The main reason endometrial ablation is offered is heavy menstrual bleeding (sometimes called menorrhagia) that has not improved with first-line treatments such as oral medications or a hormonal intrauterine device (IUD). The American College of Obstetricians and Gynecologists (ACOG) describes ablation as an option for women with heavy bleeding who have completed childbearing and in whom medical therapy has either failed, caused side effects, or is not appropriate.

Common situations in which doctors discuss ablation include:

• Periods that consistently soak through a pad or tampon every one to two hours
• Periods that last longer than seven days
• Passing large blood clots regularly
• Iron-deficiency anaemia caused by menstrual bleeding
• Bleeding that interferes with work, sleep, exercise, or relationships
• Heavy bleeding that has not responded to tranexamic acid, hormonal pills, or a levonorgestrel IUD

Before ablation is considered, doctors typically investigate the cause of the bleeding. This usually includes a pelvic examination, an ultrasound, blood tests for anaemia and thyroid function, and often a sampling of the endometrium (an endometrial biopsy) to rule out pre-cancerous changes or cancer of the uterine lining. Sometimes hysteroscopy — a thin camera passed through the cervix to look inside the uterus — is used to check for polyps or fibroids.

Ablation works best when the uterus is relatively normal in shape and size and when the bleeding is not being driven by a structural problem that needs to be removed first (such as a large polyp or submucosal fibroid). Many doctors will treat those structural causes — for example, by removing a polyp during hysteroscopy — before, or instead of, ablation.

Who Is a Candidate for Endometrial Ablation?

Endometrial ablation is generally considered for women who:

• Have heavy or prolonged menstrual bleeding that affects their quality of life
• Have completed their family and do not want future pregnancies
• Are pre-menopausal (ablation is not used after menopause and is less effective close to menopause when periods are already changing)
• Have had cancer and pre-cancer of the uterus ruled out
• Have a uterus of a size and shape suitable for the chosen technique

Ablation is generally not recommended for women who:

• Want to become pregnant in the future
• Have known or suspected endometrial cancer or pre-cancerous changes (atypical hyperplasia)
• Have an active pelvic infection
• Are pregnant
• Have certain anatomical issues such as a very enlarged uterus, large fibroids inside the cavity, or a uterine shape that the device cannot treat safely
• Have had a previous classical caesarean or certain uterine surgeries that thin the uterine wall, depending on the technique

Age matters in the discussion. Younger women (in their 30s) tend to have a higher chance of needing a repeat procedure or hysterectomy later, because they have more years until menopause for the endometrium to potentially regrow. Women closer to menopause often have more durable results. This is a discussion to have with your gynaecologist based on your individual circumstances.

Alternatives to Endometrial Ablation

Endometrial ablation is one of several options for heavy menstrual bleeding. Major guidelines, including those from NICE in the UK and ACOG in the US, recommend that medical and less invasive options be tried first in most cases.

Medical treatments

First-line treatments for heavy menstrual bleeding generally include:

• Levonorgestrel-releasing intrauterine device (LNG-IUD): A small hormonal device placed in the uterus. It releases a low dose of progestogen locally, often reducing bleeding dramatically over several months. NICE describes this as the first-line option for many women with heavy menstrual bleeding without structural cause.
• Tranexamic acid: A non-hormonal tablet taken during periods to reduce bleeding by helping blood clot more effectively.
• Non-steroidal anti-inflammatory drugs (NSAIDs): Such as mefenamic acid or ibuprofen, which can reduce bleeding and cramping.
• Combined oral contraceptive pills: Can reduce bleeding and regulate cycles.
• Oral or injected progestogens: Used in certain patterns to reduce bleeding.
• GnRH analogues: Medications that temporarily switch off ovarian hormone production. These are usually short-term and used in specific circumstances.

Procedural alternatives

• Hysteroscopic removal of polyps or fibroids: If a polyp or small fibroid inside the cavity is the cause, removing it may resolve the bleeding without ablation.
• Uterine artery embolisation: A radiology procedure that blocks blood supply to fibroids, used when fibroids are the cause.
• Myomectomy: Surgical removal of fibroids while preserving the uterus, an option when fibroids are the problem and future fertility is wanted.
• Hysterectomy: Surgical removal of the uterus. This is the only treatment that guarantees no further menstrual bleeding and no chance of recurrence, but it is a larger operation with a longer recovery. Hysterectomy is sometimes chosen when ablation has not worked, or when a woman prefers a definitive solution.

The choice between these options depends on the cause of bleeding, the size and shape of the uterus, age, future pregnancy plans, other health conditions, and personal preference. Many women find that a hormonal IUD provides enough relief; others, after trying medications, prefer to move on to ablation; some go directly to hysterectomy. There is no single right path.

Types of Endometrial Ablation

Several different techniques are used to destroy the endometrium. They fall broadly into two groups: resectoscopic (first-generation) techniques, which use a hysteroscope and require the doctor to treat the lining piece by piece under direct vision; and non-resectoscopic (second-generation) techniques, which use a device that delivers energy to the whole uterine cavity at once. Most ablations performed today use second-generation devices because they are quicker, do not require the same level of surgical skill with a resectoscope, and have a strong safety record.

Radiofrequency ablation

A small triangular mesh device is passed through the cervix and opens to fit the shape of the uterine cavity. It delivers radiofrequency energy that heats and destroys the lining in around 90 seconds to two minutes. This is one of the most commonly used techniques worldwide.

Thermal balloon ablation

A soft balloon is placed inside the uterus and filled with heated fluid. The hot fluid destroys the lining over about eight minutes. This was one of the earlier non-resectoscopic methods and remains in use.

Hydrothermal ablation

Heated saline (salt water) is circulated inside the uterus under direct vision through a hysteroscope. It can treat irregularly shaped cavities that some other devices cannot.

Cryoablation

A probe is placed in the uterus and uses extreme cold to freeze and destroy the lining. Several freeze cycles are performed in different parts of the cavity. Cramping tends to be less intense with cryoablation because cold has a numbing effect.

Microwave ablation

A probe delivers microwave energy to heat the lining. Treatment takes a few minutes. Microwave devices are less commonly used now in many centres but remain available.

Resectoscopic ablation (rollerball or loop)

An older technique still used in selected cases. A hysteroscope with an electrical loop or rollerball is used to burn or shave away the endometrium under direct vision. It allows treatment of unusual cavity shapes and can be combined with removal of polyps or small fibroids, but it requires more surgical skill and carries slightly higher risks of fluid overload from the distension medium used.

For most women with a normally shaped cavity, the second-generation devices give similar results. Which device a particular gynaecologist uses often depends on training, availability, and the specific features of the uterus.

Preparing for Endometrial Ablation

Preparation usually begins a few weeks before the procedure.

Investigations

Before ablation, your doctor will typically arrange:

• A pelvic ultrasound to assess the size and shape of the uterus and look for fibroids or polyps
• An endometrial biopsy to make sure there is no cancer or pre-cancer of the lining
• Sometimes a hysteroscopy to look inside the uterus
• Blood tests including a complete blood count, and sometimes thyroid function tests
• A pregnancy test close to the procedure date

Thinning the lining

Ablation works better when the endometrium is thin at the time of the procedure. Doctors may achieve this by:

• Scheduling the procedure right after a period
• Prescribing a short course of hormonal medication (such as a progestogen or a GnRH analogue) for a few weeks beforehand
• Performing a brief curettage at the start of the procedure to remove the lining mechanically

Contraception and pregnancy

You must not be pregnant at the time of ablation. Reliable contraception is needed in the weeks leading up to the procedure. Your doctor will also discuss contraception after ablation, because pregnancy can still happen and is dangerous if it does.

Medications

Tell your doctor about all medications you take, including blood thinners, aspirin, supplements, and herbal remedies. Some need to be stopped before the procedure. You may be advised to take a pain reliever such as ibuprofen an hour or two before the procedure to reduce cramping.

On the day

You will usually be asked to:

• Avoid food and drink for several hours beforehand if you are having sedation or general anaesthesia
• Bring a sanitary pad (not a tampon) for after the procedure
• Arrange for someone to drive you home if you are having sedation or anaesthesia

What Happens During Endometrial Ablation

Endometrial ablation is usually an outpatient procedure. Many women go home within a few hours.

Anaesthesia

Ablation can be done under:

• Local anaesthesia with sedation: Numbing the cervix with injections, combined with medications to relax you
• Regional anaesthesia: A spinal block
• General anaesthesia: You are fully asleep

The choice depends on the technique, the anatomy of your uterus, your preferences, and your doctor’s usual practice. Many second-generation ablations can be done under local anaesthesia with sedation, sometimes even in an office setting.

The procedure step by step

1. You lie on an examination table with your feet supported, similar to a pelvic exam position.
2. The anaesthetic is given.
3. The doctor places a speculum in the vagina to see the cervix.
4. The cervix is cleaned and gently dilated so the device can pass through.
5. A hysteroscope may be used first to inspect the uterine cavity.
6. The ablation device is introduced through the cervix into the uterus.
7. The device delivers energy — heat, cold, microwave, or radiofrequency — for the time required by the specific technique (usually 90 seconds to ten minutes).
8. The device is removed, and the uterus is checked.
9. You are taken to a recovery area to wake up from sedation or anaesthesia.

The total time in the operating room is often under 30 minutes. The energy delivery itself is much shorter.

Recovery and Healing

Most women recover quickly from endometrial ablation. Because there are no abdominal incisions, recovery is much faster than after hysterectomy.

The first 24 hours

You may have:

• Cramping similar to strong period pain, usually relieved by over-the-counter pain medication
• Nausea, particularly if you had general anaesthesia or sedation
• A watery, pinkish, or bloody discharge
• Mild fatigue

Cramping is often most intense in the first few hours and then settles. A heating pad on the lower abdomen can help.

The first one to two weeks

• Most women return to normal activities within a few days to a week
• A watery discharge, sometimes mixed with blood, is normal and can last for several weeks as the uterus heals and the destroyed lining sheds
• Tampons, sexual intercourse, douching, and swimming are usually avoided for about two weeks to reduce infection risk
• Light exercise such as walking is encouraged; heavy lifting and intense exercise are usually delayed

The first few months

When to call your doctor:

• Fever above 38°C (100.4°F)
• Heavy bleeding (soaking a pad an hour for several hours)
• Worsening rather than improving pelvic pain
• Foul-smelling vaginal discharge
• Difficulty passing urine
• Severe nausea or vomiting

Risks and Complications

Endometrial ablation has a good overall safety record, but no procedure is without risks. Serious complications are uncommon. Discussing the specific risk profile of the technique your doctor is offering is an important part of consent.

Short-term risks

• Cramping and pain: Almost universal, usually manageable with simple pain relief.
• Nausea and vomiting: Often related to anaesthesia or pain medication.
• Vaginal infection or endometritis: Treated with antibiotics if it occurs.
• Uterine perforation: A small hole made in the wall of the uterus by an instrument. Rare, but if it happens, it can occasionally involve injury to nearby organs and may require additional treatment.
• Thermal injury to nearby organs: Rare but serious. Modern devices have safety features to reduce this risk.
• Fluid overload: A specific risk of resectoscopic ablation when fluid is used to distend the uterus. Careful monitoring during the procedure minimises this.
• Bleeding: Heavy immediate bleeding is uncommon.

Longer-term risks and considerations

• Treatment failure: Some women continue to have bleeding heavier than they wanted. A proportion will go on to need a repeat ablation, other procedures, or hysterectomy.
• Late-onset pain (post-ablation syndrome): In some women, particularly those who have had a previous tubal ligation, scarring inside the uterus can trap blood that is still being produced in pockets of lining, causing cyclical pain. This is sometimes called “post-ablation tubal sterilisation syndrome.”
• Pregnancy after ablation: Pregnancy is significantly less likely but possible. When it does occur, the risk of miscarriage, abnormal placentation, and other serious complications is high. Reliable contraception or sterilisation is essential.
• Difficulty diagnosing future uterine problems: Scarring inside the uterus can make future hysteroscopic procedures or sampling of the lining technically harder. This is one reason ablation is not used when there is suspicion of endometrial cancer or pre-cancer.

Life After Endometrial Ablation

What to expect from your periods

Results vary. Looking across published studies, most women see a significant reduction in bleeding and many become free of periods altogether. Others continue to have light to moderate periods. A smaller proportion does not see enough improvement to call the procedure a success.

• No bleeding at all (amenorrhoea)
• Light spotting or very light periods
• Light to moderate normal periods
• Continued heavy bleeding (treatment failure)

Younger women, women with very enlarged uteri, women with adenomyosis, and women with very heavy pre-procedure bleeding tend to be more likely to need further treatment over time. Your gynaecologist can give you a more individual estimate based on your situation.

Contraception and pregnancy after ablation

Even if you stop having periods, ovaries continue to produce eggs and pregnancy is still possible. Pregnancy after ablation is high-risk. Reliable contraception until menopause is essential. Options include:

• Long-acting reversible contraception such as a non-hormonal IUD (the suitability of an IUD after ablation depends on the uterine cavity and is decided case by case)
• Hormonal contraception
• Permanent contraception (tubal occlusion or a partner’s vasectomy)

Your gynaecologist will discuss which methods suit you. Endometrial ablation itself is not a method of contraception or sterilisation.

Hormones and menopause

Ablation does not change the function of your ovaries. You will continue to produce hormones in your normal pattern and will go through menopause at your usual age. Symptoms such as hot flushes, mood changes, or vaginal dryness, when they happen, will happen at the natural time. Because periods may already be very light or absent after ablation, the bleeding cues that mark approaching menopause may be missing.

Cervical screening and other gynaecological care

Routine cervical screening (Pap smear or HPV testing) continues as usual. Ablation does not affect the cervix or the risk of cervical cancer. Pelvic examinations and other gynaecological care continue normally.

If bleeding comes back or never improves

If your periods remain too heavy after ablation, or if heavy bleeding returns months or years later, talk to your doctor. Options at that stage include:

• Further investigations to rule out new causes such as polyps, fibroids, or, in older women, endometrial cancer
• Medical treatment
• Repeat ablation in selected cases
• Hysterectomy

New or unexpected bleeding after a period of no bleeding, especially around or after menopause, always needs prompt evaluation.

Frequently Asked Questions

Will I still have periods after endometrial ablation?

You might or might not. Some women stop having periods completely; others have much lighter periods than before; a smaller group continues to have meaningful bleeding. The result usually settles three to six months after the procedure.

Is endometrial ablation the same as a hysterectomy?

No. A hysterectomy removes the uterus. Ablation leaves the uterus in place and only destroys the lining. Ablation is a shorter, less invasive procedure with a faster recovery, but it is not as definitive: bleeding can come back, and a proportion of women later choose hysterectomy. Hysterectomy is the only treatment that guarantees no further menstrual bleeding.

Will the procedure hurt?

You should not feel pain during the procedure itself because of the anaesthesia or sedation. Cramping afterwards is common and usually feels like a strong period. It is generally well controlled with over-the-counter pain relief.

How long does it take to get back to normal life?

Most women feel well enough to return to desk-based work and light activities within one to three days. Watery or bloody discharge can continue for several weeks. Sexual intercourse, tampons, and swimming are usually avoided for around two weeks.

Can endometrial ablation be reversed?

No. The destroyed lining cannot be restored. This is one of the main reasons ablation is offered only to women who have completed their families.

Can I still get pregnant after ablation?

Pregnancy after ablation is less likely but possible — and when it happens it is high-risk for both mother and baby. Reliable contraception until menopause is essential. Ablation is not a sterilisation procedure.

Does ablation cause early menopause?

No. Ablation does not affect the ovaries. Your hormones continue as normal, and menopause happens at the natural age.

What happens if my bleeding comes back?

Your doctor will investigate the cause. Treatment can range from medication to a repeat ablation or hysterectomy. Any bleeding that starts after a long period without bleeding, particularly around or after menopause, needs evaluation.

Will ablation help if my heavy bleeding is caused by fibroids?

It depends on the size, number, and location of the fibroids. Small fibroids may not affect results much; large fibroids inside the uterine cavity often need to be treated separately. Your gynaecologist will assess your uterus and recommend the most suitable approach.

How is ablation different from a D&C (dilation and curettage)?

A D&C scrapes away the surface of the lining and is usually used for diagnosis or to manage acute bleeding. The lining quickly regrows, so the effect on future periods is temporary. Ablation destroys the lining more deeply, with the aim of long-term reduction in bleeding.

Can ablation be combined with other procedures?

Yes. It is often combined with hysteroscopic removal of polyps. It is generally not combined with tubal sterilisation because of the increased risk of post-ablation tubal sterilisation syndrome, although individual circumstances vary and this is a discussion to have with your doctor.

Conclusion

Endometrial ablation is a short, well-established procedure that can transform daily life for women whose periods have become unmanageable. It is most useful for women who have completed their families, whose heavy bleeding has not responded to simpler treatments, and who would prefer to avoid the larger operation of hysterectomy. Recovery is quick and the procedure itself usually takes less than half an hour.

It is not a perfect solution for everyone. Results vary, the procedure cannot be reversed, contraception must continue, and a proportion of women eventually need further treatment. Whether ablation is the right option, which technique suits your uterus, and how it compares to alternatives such as a hormonal IUD or hysterectomy in your situation are decisions to make in conversation with your gynaecologist, based on your anatomy, your medical history, and what matters most to you.
