When Is Hysteroscopy Recommended? Abnormal Bleeding, Fertility Work-Up and Ultrasound Findings

The scan report arrives before the appointment does. Somewhere in the second paragraph sits a phrase like “endometrial thickening” or “possible polyp,” and the sentence that follows, the one that says the gynecologist will discuss a hysteroscopy, suddenly feels much louder than the rest of the page. For a lot of people, that is the first time they have seen the word.

The question underneath is simple: when is hysteroscopy recommended, and is this really one of those times? The honest answer is that a hysteroscopy is not a reflex. It is chosen when the information a doctor needs lives inside the uterine cavity and cannot be reliably gathered from outside it. Bleeding that behaves oddly, a fertility investigation that has stalled, a shadow on a scan that could be one of three different things: these are the situations where looking directly tends to beat guessing.

This explainer walks through those situations in plain language, including when doctors usually suggest waiting, what the procedure feels like, and what the days afterward tend to look like.

When is hysteroscopy recommended? The short version

A hysteroscopy is a procedure in which a thin telescope, called a hysteroscope, is passed through the vagina and cervix so the inside of the uterus can be seen on a screen. The uterine cavity is normally a flat, closed space, so a little fluid or gas is used to open it gently for viewing. Because the camera is looking at the actual lining, the endometrium, it can settle questions that ultrasound can only raise.

Doctors tend to reach for it in four broad situations. The first is bleeding that does not fit the expected pattern: periods that have become much heavier, bleeding between periods, bleeding after sex, or any bleeding at all after menopause. The second is a fertility work-up, particularly when scans hint at something inside the cavity or when pregnancy has been lost more than once. The third is an ultrasound finding that needs confirming, such as a polyp, a fibroid bulging into the cavity, or a lining that looks thicker than expected. The fourth is a practical one: locating a displaced contraceptive coil, or checking the cavity after a previous procedure.

None of these is an automatic ticket to the procedure room. The NHS describes hysteroscopy as a way to investigate symptoms or problems, and to treat some of them, which is a useful frame: it is a tool, not a verdict. A doctor weighs the symptom, the person’s age and history, what less invasive tests have already shown, and whether the answer would change the plan. When the honest answer is “yes, seeing inside would change what we do,” a hysteroscopy is usually on the table. When the answer is “probably not,” a good team will say so and suggest watchful waiting or a different test.

What actually happens during a hysteroscopy

Most diagnostic hysteroscopies take place as outpatient procedures, and many are done without a general anesthetic. The NHS notes that the examination itself often takes around 5 to 10 minutes when it is purely for looking, and up to about 30 minutes if a small treatment is carried out at the same time.

The sequence is fairly consistent. You lie as you would for a smear test. A speculum, the instrument that holds the vaginal walls apart, may be used, though newer, narrower scopes sometimes make it unnecessary. The hysteroscope, often thinner than a drinking straw, is passed through the cervix. Sterile fluid flows through it to open the cavity, and the image appears on a monitor that you can usually watch too if you want to. The doctor inspects the lining, the two openings where the fallopian tubes enter, and the shape of the cavity, then may take a tiny sample of tissue, called a biopsy, for the laboratory.

What does it feel like? Descriptions range from mild period-type cramping to a sharper pain that eases once the scope is out. The NHS is candid that some people find it very painful, and that you should tell the clinician, who can stop at any point. A local anesthetic injected around the cervix, oral pain relief taken beforehand, or a general anesthetic are all options, and the choice is a conversation rather than a default. Some units use a “vocal local” approach, where a nurse talks with you throughout; some people find this genuinely helpful, others prefer to be asleep. Neither preference is wrong.

Afterward you usually rest briefly, are offered something to drink, and can go home the same day. The Cleveland Clinic describes the findings being discussed with you either straight away, for what was seen, or after biopsy results return.

Hysteroscopy for abnormal bleeding: why the pattern matters

Abnormal uterine bleeding is the single most common reason people end up asking when hysteroscopy is recommended, but the word “abnormal” covers very different stories, and the pattern shapes the decision.

Heavy periods on their own are not usually a fast track to hysteroscopy. The NHS pathway for heavy menstrual bleeding starts with a history, an examination, blood tests for anemia, and often an ultrasound. Hysteroscopy comes into the picture when that initial work-up suggests something structural inside the cavity, when treatment has not controlled the bleeding, or when the bleeding pattern has features that call for a direct look.

Those features include bleeding between periods (intermenstrual bleeding), bleeding after intercourse, a sudden change in a previously predictable cycle, and persistent irregular bleeding in someone over 45 or in anyone with risk factors for changes in the lining, such as long stretches of cycles without ovulation. In these cases the question is not just “why so much?” but “is something growing in there?” Polyps, which are soft overgrowths of the lining, and submucosal fibroids, muscular lumps that push into the cavity, both bleed unpredictably and both are easier to see and treat with a hysteroscope than to guess at from a scan.

Hysteroscopy also lets the doctor take a targeted biopsy from the exact spot that looks different, instead of a blind sample that might miss a small area. That precision is the practical reason it sits above a simple lining biopsy in many pathways once an abnormality is suspected. If your bleeding is heavy but regular and the ultrasound is unremarkable, do not be surprised if your doctor suggests medical options first and keeps hysteroscopy in reserve. That is not dismissiveness; it is the sequence most guidelines describe.

Bleeding after menopause: why it usually goes straight to investigation

There is one bleeding pattern where the threshold drops sharply: any vaginal bleeding after menopause, meaning bleeding that occurs a year or more after periods have stopped. The NHS advises seeing a GP about postmenopausal bleeding even if it happens only once and is very light.

Why the urgency? Most postmenopausal bleeding turns out to have a benign cause. Thinning and fragility of the vaginal and uterine lining after estrogen falls is common, as are polyps. But a small proportion of cases are caused by endometrial hyperplasia, a thickening of the lining that can sometimes progress, or by endometrial cancer, and the only symptom of endometrial cancer is often this exact kind of bleeding. Because it is usually found at an early stage when bleeding is investigated promptly, guidelines treat postmenopausal bleeding as a reason for rapid assessment rather than watchful waiting.

The typical route is a transvaginal ultrasound first. If the lining measures thin and even, and bleeding does not recur, that may be reassurance enough. If the lining measures above the threshold that local guidelines use, or looks irregular, or bleeding continues despite a thin lining, a hysteroscopy with biopsy is the usual next step. The camera can spot a focal lesion that a blind sample would miss, and the biopsy gives the laboratory tissue to examine.

People on hormone replacement therapy sometimes have expected bleeding in the early months of certain regimens, and people with unrelated causes such as bladder or bowel bleeding can mistake the source. Your doctor will ask about these. Even so, the principle holds: after menopause, bleeding is investigated, not observed. If this is the reason you are reading, the most useful thing you can do is keep the appointment rather than wait to see whether it happens again.

Hysteroscopy before IVF and in the fertility work-up

A fertility investigation looks at three things: whether eggs are released, whether sperm can reach them, and whether an embryo can implant and grow. Hysteroscopy speaks to the third. The uterine cavity is where implantation happens, and anything that distorts it, occupies it or inflames it can, in theory, get in the way.

The Cleveland Clinic and Johns Hopkins both list infertility and repeated miscarriage among the reasons a hysteroscopy may be suggested. The findings a doctor is looking for include polyps, submucosal fibroids, intrauterine adhesions (bands of scar tissue, sometimes following a previous procedure or infection), and congenital differences in shape such as a septum, a wall of tissue partly dividing the cavity from birth.

Where things get nuanced is the question of routine hysteroscopy before IVF for everyone. IVF, in vitro fertilization, is the process of fertilizing eggs outside the body and transferring an embryo into the uterus. It is tempting to assume that checking the cavity first can only help. The evidence is more mixed than that. Large trials of routine screening hysteroscopy before a first IVF cycle in people with a normal ultrasound have not consistently shown improved live birth rates, which is why many guidelines do not recommend it as a blanket step. What they do support is a hysteroscopy when there is a reason: an abnormal scan, unexplained repeated implantation failure, or recurrent pregnancy loss.

That distinction matters for expectations. If your fertility team suggests a hysteroscopy, ask what they are looking for and what they would do if they found it. If they do not suggest one, and your ultrasound and saline scan are normal, that is a defensible, guideline-consistent position rather than a missed step. Reproductive decisions are individual, and the treating team is the right place for that conversation.

When an ultrasound finding leads to hysteroscopy

Ultrasound is the workhorse of gynecology because it is quick, painless and safe. It also has limits. Sound waves show shapes and textures; they do not show color, surface detail or what tissue is made of. A hysteroscope shows all three. The table below sets out common scan phrases and how they typically translate into next steps. It is a guide to the conversation, not a rulebook; your doctor will factor in symptoms, age and history.

Ultrasound finding	What it might mean	Usual next step
Focal echogenic lesion in the cavity	Endometrial polyp, small fibroid, clot or thickened fold	Saline infusion scan or hysteroscopy to confirm and often remove
Submucosal fibroid distorting the cavity	Fibroid pressing into the lining, linked to heavy bleeding or fertility concerns	Hysteroscopy to assess how much sits inside the cavity; operative removal may be discussed
Thickened or irregular endometrium after menopause	Hyperplasia, polyp, or less commonly cancer	Hysteroscopy with directed biopsy
Thickened endometrium before menopause	Often normal for cycle phase; sometimes hyperplasia or polyp	Repeat scan at a different cycle point; hysteroscopy if persistent or symptomatic
Suspected septum or unusual cavity shape	Congenital variation; may matter for fertility	3D ultrasound or MRI, then hysteroscopy to confirm and possibly treat
Coil not seen in expected position	Displaced or embedded device	Hysteroscopy to locate and retrieve

One finding deserves a specific caution. A “thickened endometrium” in someone who still has periods can simply reflect where they are in the cycle; the lining is at its thickest just before a period. A repeat scan in the days after bleeding often resolves the question without any procedure at all, which is one reason radiologists ask for the date of your last period.

Who should not have a hysteroscopy, and who is usually asked to wait

Hysteroscopy is suitable for most adults with a uterus, but there are situations where the answer is “not now” or “not this test.”

Pregnancy is the clearest reason to hold off. The NHS states plainly that a hysteroscopy should not be carried out if you are pregnant, which is why clinics ask for a pregnancy test on the day if there is any possibility. Instrumenting and distending a pregnant uterus carries obvious risks to the pregnancy.

An active pelvic infection is another reason to wait. Passing an instrument through an infected cervix can carry organisms upward into the uterus and tubes. If you have an unusual discharge, pelvic pain and fever, the team will usually treat the infection first and reschedule.

Heavy active bleeding is a practical rather than a safety problem: blood clouds the view, so the procedure may be rescheduled for a clearer window. Known cervical cancer is a contraindication in most guidelines, because the diagnostic route and treatment planning differ. A very tight or scarred cervix, sometimes seen after menopause or previous surgery, does not rule out hysteroscopy but may prompt the team to plan cervical preparation or a general anesthetic rather than an awake procedure.

Then there is the group who are not so much unsuitable as unlikely to benefit. If you have regular heavy periods, a normal ultrasound, and no red-flag features, most pathways try medical management before anyone reaches for a scope. If a fertility work-up shows a normal cavity on ultrasound and saline scan, routine hysteroscopy is not standard. And if you are managing well on a treatment that is working, a hysteroscopy “just to check” rarely adds anything.

People with significant heart or lung conditions, bleeding disorders, or previous difficult anesthetics can usually still have the procedure, but the planning changes. Tell the team everything; it shapes the where and how, not usually the whether.

When in the cycle is hysteroscopy done, and what is the optimal time?

If you still have periods, timing is not a formality. Johns Hopkins notes that hysteroscopy is best performed during the first week or so after your period ends, and most clinics aim for the early follicular phase: the window after bleeding stops and before ovulation.

Three reasons drive this. First, the view. Right after a period the endometrium is at its thinnest, so the camera sees the cavity walls clearly rather than looking through thick, ruffled tissue that can mimic a polyp. Second, pregnancy safety. Scheduling before ovulation makes an unrecognized early pregnancy very unlikely, though a test on the day is still routine. Third, comfort and bleeding. The cervix is generally easier to pass in this phase, and there is no menstrual flow to obscure things.

What if your cycles are irregular or unpredictable? The team may ask you to call on the first day of bleeding so the appointment can be booked into the right window, or they may use a short course of medication to control the cycle first; that is a decision for the prescribing clinician and depends on your situation. If you are on hormonal contraception that suppresses bleeding, or using a hormonal coil, the lining tends to stay thin throughout, and timing matters less.

After menopause, there is no cycle to work around, so the procedure can be booked for whenever is convenient, usually as promptly as possible if postmenopausal bleeding is the reason.

One more practical note: if you are still bleeding on the day of a scheduled hysteroscopy, ring the clinic. Light spotting is often fine and the procedure may go ahead. Heavier flow may mean a short postponement, which is frustrating but tends to produce a better, more useful examination.

Diagnostic vs operative hysteroscopy: same tool, two different visits

The word covers two experiences that can feel quite different, and knowing which one is planned helps set expectations.

A diagnostic hysteroscopy is a look, sometimes with a small biopsy. It uses a slim scope, is often done awake in an outpatient room, and the NHS describes it as typically lasting only minutes. You can usually go home shortly afterward and the main after-effects are cramping and light spotting.

An operative hysteroscopy is a look plus a treatment. A slightly wider scope carries tiny instruments, or a device that shaves or removes tissue, through the same channel. Common operative tasks include removing a polyp, taking out a submucosal fibroid, cutting a septum, dividing adhesions, retrieving a displaced coil, or, for some people with heavy bleeding who have completed their family, treating the lining itself. Operative procedures take longer, may involve a general anesthetic or a spinal, and carry a somewhat higher chance of the complications described later, though the procedure remains low risk overall.

Increasingly, units offer a “see and treat” approach, where a small polyp found during a diagnostic look is removed in the same session with a very fine instrument, saving a second visit. Whether that is possible depends on what is found, how you are coping, and what you agreed beforehand. Consent forms often include a line allowing removal of small polyps if seen; read it and ask questions if anything is unclear.

The practical difference for you: a diagnostic procedure rarely needs someone to drive you home unless you had sedation; an operative one under anesthetic will. A diagnostic look rarely needs time off beyond the day; an operative procedure may need a few days, as covered in the recovery section below.

Alternatives: when hysteroscopy is not the best next step

Because hysteroscopy is precise, it can be tempting to treat it as the gold standard for every uterine question. It is not always the most sensible first move, and a good team will lay out the alternatives.

Transvaginal ultrasound is nearly always first. It is quick, needs no preparation, and gives a reasonable picture of the lining thickness, the uterine wall and the ovaries, which a hysteroscope cannot see at all. If the scan is normal and symptoms are mild, that may be where the work-up pauses.

Saline infusion sonography, also called a sonohysterogram, sits between the two. A small amount of sterile saline is placed in the uterus through a fine tube during an ultrasound, outlining the cavity. It is very good at revealing polyps and submucosal fibroids and is generally less uncomfortable than hysteroscopy. Many fertility clinics use it as their standard cavity check and reserve hysteroscopy for confirming or treating what it finds.

An endometrial biopsy without a camera, using a thin suction tube in the clinic, can sample the lining quickly. Its weakness is that it samples blindly, so it can miss a small focal lesion. That is why it works well when the concern is a general change in the lining and less well when the scan shows a specific lump.

MRI has a role in mapping fibroids and clarifying congenital shape differences, particularly when surgery is being planned, though it is not used for routine bleeding assessment.

Then there is the option of doing nothing invasive for now. Medical management of heavy periods, including hormonal and non-hormonal options chosen by the prescribing clinician, is the first step in most guidelines when there are no red flags. Hysteroscopy remains available if things change. Asking “what would we lose by waiting?” is a fair and useful question.

How safe is a hysteroscopy? Risks in plain numbers

Hysteroscopy is generally considered a low-risk procedure, and the NHS describes it as very safe, while being clear that no procedure is risk-free. Knowing the specific risks helps you weigh them and recognize problems early.

The most common event is not dangerous but is worth expecting: feeling faint or lightheaded during or just after an awake procedure. The NHS puts this at around 1 in every 200 people having hysteroscopy without anesthetic. It is a vagal reflex, similar to what some people feel during a smear test, and it passes with lying down.

Pain is the other frequent issue. Cramping is expected; severe pain is not something to endure silently. You can ask the clinician to pause or stop at any time.

Infection of the uterus can occur. The NHS lists warning signs as a smelly discharge, fever and heavy bleeding, usually treated by your GP. Accidental damage to the uterus, known as perforation, where the instrument passes through the wall, is described by the NHS as uncommon; it may need a stay in hospital and occasionally a further operation to repair. Damage to the cervix is rarer still and usually simple to repair. Heavy bleeding is uncommon and more likely after operative procedures under general anesthetic.

Operative hysteroscopy carries some additional, rare considerations: fluid from the distension medium being absorbed into the bloodstream, which the team monitors closely, and, after treatments that remove lining tissue, the formation of adhesions. Anesthetic risks apply if you are asleep, and are assessed beforehand.

Put together, the picture is of a procedure where minor, short-lived effects are common and serious complications are rare. That balance is exactly why it can be offered in an outpatient setting to so many people, and also why the follow-up advice on red flags matters.

What the following days and weeks usually look like

Recovery depends heavily on which version you had. After a diagnostic hysteroscopy without anesthetic, the NHS says most people feel able to return to normal activities the same day or the next, and can eat and drink as usual straight away. Period-type cramps in the first day or two are typical and usually respond to the pain relief you would normally take for a period; check with the team about what is appropriate for you.

Spotting or light bleeding for a few days is common. The NHS suggests using sanitary pads rather than tampons during this time to reduce infection risk, and advises avoiding sex until any bleeding has stopped. If you had a biopsy, results usually take a couple of weeks to come back from the laboratory, and the team will tell you how and when you will hear.

After an operative hysteroscopy under general anesthetic, the pattern is slower. You will need someone to take you home and stay with you overnight, and the NHS advises not driving, drinking alcohol or signing legal documents for 24 hours after a general anesthetic. Bleeding may be a little heavier and last longer, and tiredness is common for a few days. Many people take a few days off work; how many depends on what was done and what your work involves.

A watery discharge can follow procedures that treat the lining and may persist for some weeks. Your team should tell you what to expect for your specific procedure.

Emotionally, the waiting period for results is often the hardest part. If you find yourself checking your phone constantly, know that the delay reflects laboratory processing time, not bad news. Follow-up may be a phone call, a letter or an appointment; ask which so you are not left guessing.

What people often get wrong about hysteroscopy

A few persistent ideas circulate about this procedure, and correcting them makes for calmer decisions.

“It’s basically a smear test.” It is not. The setup looks similar, but a hysteroscope passes through the cervix into the uterus, which a smear does not. Many people find it more uncomfortable than a smear, and the NHS explicitly acknowledges that some find it very painful. Expecting a smear and getting something sharper is a recipe for a bad experience; asking about pain relief options in advance is a better plan.

“If they’ve suggested it, they must think it’s cancer.” Hysteroscopy is recommended for many benign reasons, and most findings, even in postmenopausal bleeding, turn out to be polyps, thin fragile lining or nothing at all. The procedure is used precisely because it can rule serious things out, not only in.

“Everyone should have one before IVF.” As discussed earlier, routine screening hysteroscopy in people with a normal ultrasound has not consistently improved outcomes in large trials, and many guidelines do not recommend it as a blanket step. It is indicated when there is a reason to look.

“A normal ultrasound means the uterus is definitely fine.” Ultrasound is excellent but can miss small polyps and cannot characterize surface changes. Conversely, a “thickened lining” on a scan taken just before a period may be entirely normal. Scans are read in context.

“Hysteroscopy will fix my heavy periods.” A diagnostic hysteroscopy looks; it does not treat. An operative hysteroscopy may remove a specific cause, such as a polyp, but heavy bleeding has many causes and not all live inside the cavity. Bleeding that stems from the muscle wall, from hormone imbalance or from a clotting tendency needs different approaches.

“You must have a general anesthetic.” Most diagnostic procedures are done awake or with local anesthetic. General anesthetic is one option among several, not a requirement.

Questions to ask your care team before a hysteroscopy

The most useful appointments are the ones where you arrive with questions written down. These are the ones that tend to change decisions or ease the day itself.

• What specifically are you looking for, and how would finding it change my treatment?
• Have I had the less invasive tests first, such as ultrasound or a saline scan, and what did they show?
• Is this planned as a diagnostic look only, or might you treat something at the same time? What have I agreed to on the consent form?
• What are my options for pain relief and anesthesia, and what do you recommend for someone with my history?
• Can I ask you to stop if it becomes too painful, and how would that work?
• What day of my cycle should this be scheduled for, and what should I do if I am bleeding on the day?
• Will I need someone to bring me home? Should I take time off work?
• What are the signs that something is wrong afterward, and who do I call, including out of hours?
• If you take a biopsy, how long until results, and how will I receive them?
• What happens if you cannot get a clear view or cannot pass the cervix?
• What would happen if I chose to wait instead?

You are entitled to bring someone with you, to ask for a chaperone, and to request a general anesthetic if you prefer one, though the team will discuss whether that is the safest route for you. You are also entitled to change your mind, including on the day. A hysteroscopy done with your full understanding and consent is a different experience from one that feels rushed, and clinicians generally welcome the questions.

When to call your doctor

Most people recover from hysteroscopy with nothing more than cramps and spotting. A small number develop problems that need prompt attention, and knowing the signs means you can act early rather than wait and worry.

Contact the clinic, your doctor or an urgent care service the same day if you notice any of the following after a hysteroscopy:

• Bleeding heavier than a normal period, soaking through a pad in an hour or passing large clots
• Severe or worsening abdominal or pelvic pain that ordinary pain relief does not touch
• A fever, chills or feeling generally unwell
• Vaginal discharge that smells unpleasant or is dark and unusual
• Pain when passing urine that is new since the procedure, or difficulty passing urine
• Feeling faint, breathless or having a racing heart that does not settle with rest
• Persistent nausea or vomiting after a general anesthetic

Seek emergency care immediately for very heavy bleeding, collapse, or severe pain with a rigid, tender abdomen, as these can signal a perforation or significant bleeding.

The same principle applies before any procedure has happened. If you are reading this because of your own symptoms, the following warrant a prompt, non-urgent appointment rather than waiting: any bleeding after menopause, even once; bleeding between periods or after sex that persists beyond one cycle; periods that have suddenly become much heavier; and pelvic pain alongside abnormal bleeding. If you are also feeling faint, breathless or exhausted with heavy bleeding, that combination can indicate anemia and should be assessed sooner.

Whatever the finding, the decision about whether, when and how to proceed rests with you and your treating team. This article is a map of the territory, not a route for any one person.

Frequently asked questions

When would a hysteroscopy be needed?

A hysteroscopy is needed when a doctor must see inside the uterus to answer a question that scans and blood tests cannot settle. Typical reasons include bleeding after menopause, heavy or irregular bleeding that is unexplained or not responding to treatment, a fertility investigation or repeated pregnancy loss, an ultrasound suggesting a polyp, fibroid or thickened lining, and locating a displaced contraceptive coil. The treating team decides case by case.

At what point in the cycle is hysteroscopy done?

Hysteroscopy is usually done in the first half of the cycle, shortly after a period has finished and before ovulation. The lining is thinnest then, so the view is clearest, and the chance of an unrecognized early pregnancy is very low. If your cycles are irregular, the clinic may ask you to call on the first day of bleeding so the appointment can be timed. After menopause, timing is not an issue.

When is the optimal time to have a hysteroscopy?

The optimal time for someone who still has periods is generally the week or so after bleeding stops, often described as roughly the first ten days of the cycle. This window combines a thin, easy-to-read lining with minimal pregnancy risk and no menstrual flow to obscure the camera. For urgent reasons such as postmenopausal bleeding, the optimal time is simply as soon as it can be arranged.

Who should not have a hysteroscopy?

Hysteroscopy is not carried out during pregnancy, and it is usually postponed if there is an active pelvic infection or very heavy bleeding that would block the view. Known cervical cancer is a contraindication in most guidelines. People with a very tight cervix, significant heart or lung disease, or bleeding disorders can often still have the procedure but may need different planning, such as cervical preparation or a general anesthetic.

Is hysteroscopy for abnormal bleeding always necessary?

No. For heavy but regular periods with a normal ultrasound and no warning features, most guidelines suggest trying medical management first and holding hysteroscopy in reserve. It becomes more clearly indicated when bleeding is irregular, occurs between periods or after sex, continues despite treatment, appears after menopause, or when a scan shows a possible polyp, fibroid or thickened lining that needs a direct look and targeted biopsy.

Do I need a hysteroscopy before IVF?

Not routinely. Large trials of screening hysteroscopy before a first IVF cycle in people with a normal ultrasound have not consistently shown better live birth rates, so many guidelines do not recommend it for everyone. It is usually suggested when there is a specific reason: an abnormal scan, suspected polyps, fibroids, adhesions or a septum, repeated implantation failure, or recurrent pregnancy loss. Your fertility team will explain their reasoning.

How painful is a hysteroscopy without anesthetic?

Experiences vary widely. Many people describe period-like cramping that eases once the scope is removed; others find it very painful, which the NHS openly acknowledges. Pain tends to be worse with a narrow or scarred cervix or if a biopsy is taken. You can ask about local anesthetic, pain relief beforehand or a general anesthetic, and you can ask the clinician to stop at any point during the procedure.

What does an ultrasound show that makes a doctor recommend hysteroscopy?

Findings that commonly lead to hysteroscopy include a focal lump inside the cavity suggesting a polyp, a fibroid bulging into the lining, a lining that looks thicker or more irregular than expected, especially after menopause, an unusual cavity shape such as a possible septum, or a contraceptive coil not in its expected position. A thickened lining before menopause is often rechecked after a period before any procedure is arranged.

How long does recovery from a hysteroscopy take?

After a diagnostic hysteroscopy without anesthetic, most people return to normal activities the same or next day, with cramps and light spotting for a few days. After an operative hysteroscopy under general anesthetic, expect to need a lift home, to avoid driving for 24 hours, and possibly a few days off work. Bleeding may last a little longer. Biopsy results typically take a couple of weeks to return.

Can a hysteroscopy detect cancer?

A hysteroscopy allows the doctor to see areas of the lining that look abnormal and to take a targeted biopsy from them, which the laboratory then examines. The camera itself does not diagnose cancer; the tissue sample does. This directed sampling is why hysteroscopy is often preferred over a blind biopsy when a scan shows a specific lesion. Most findings, even in postmenopausal bleeding, turn out to be benign.
