A period is heavy if it is heavy for you — not if it crosses some number in a textbook. Most heavy bleeding has a findable cause and a treatment that is not an operation. Here is what counts as abnormal, the nine things that cause it, the tests you genuinely need, every treatment in the order it should be tried, and a short self-check to help you decide whether to be seen.
Periods that come closer together than every 24 days or further apart than every 38, last longer than eight days, vary in timing by more than about a week from cycle to cycle, or are heavy enough to interfere with your life. That last one has no number attached to it, and it does not need one.
Nine causes account for almost all of it, and they divide neatly into things you can see on a scan — polyp, adenomyosis, fibroid, and rarely a cancer — and things you cannot: a bleeding disorder, an ovulation problem, the lining itself, a medicine you are taking, and a short list of rarities.
Name the cause, correct the iron, and start with the least invasive treatment that fits. For most women that is a tablet or a hormonal coil, not an operation. Surgery is the right answer for a minority, and is a much better answer when it is aimed at a cause somebody has actually identified.
Ten questions, one minute. It will not diagnose you and it cannot decide anything — but it will tell you how soon this deserves an appointment, and give you something specific to say when you get there.
Nothing you enter is stored or sent anywhere. This is a conversation starter, not a medical opinion.
Four things worth knowing before anyone measures anything.
The old textbook threshold was 80 millilitres of blood loss per period. It is almost never measured, because measuring it is impractical and because it turned out not to describe the problem well. Modern guidance defines heavy menstrual bleeding as excessive loss that interferes with a woman’s physical, emotional, social or material quality of life — whether or not it crosses any number. If your period is running your life, it is heavy. You do not have to prove it.
Where volume is subjective, the rest is not. A normal cycle arrives every 24 to 38 days, bleeds for eight days or fewer, and does not vary by more than about seven to nine days between your shortest and longest cycle. Outside those, the word is not “heavy” — it is irregular, prolonged, or infrequent, and each points somewhere different.
Soaking through a pad or tampon in an hour or less, repeatedly, and passing clots larger than about two and a half centimetres, both correlate well with genuinely heavy loss. So does needing double protection, getting up at night to change, and planning your month around one week of it.
“Menorrhagia”, “metrorrhagia” and “dysfunctional uterine bleeding” were used so inconsistently that they were formally abandoned. The language now describes what is actually happening — heavy, prolonged, irregular, intermenstrual — which is more useful to you as well as to the doctor. If you would like to understand the underlying cycle first, our guide to the menstrual cycle week by week is the place to start.
Gynaecologists group these under the initials PALM–COEIN. PALM are the four you can see; COEIN are the five you cannot.
A small overgrowth of the lining, usually benign, sitting inside the cavity. Classically causes bleeding between periods or after sex rather than heavier periods. Easy to miss on an ordinary scan and easy to remove once seen. Our page on endometrial polyps explains why a normal biopsy does not rule one out.
Lining tissue growing into the muscle wall of the uterus. The signature is heavy periods and genuinely severe period pain, often in a woman in her late thirties or forties, sometimes with a uterus that feels bulky. Frequently missed for years and often mislabelled as fibroids.
Benign muscle growths. Whether they cause heavy bleeding depends almost entirely on where they sit, not how big they are — the ones inside the cavity are the troublemakers. Our fibroids page goes through the types and every option.
Uncommon, and much less likely than the internet suggests, but the reason bleeding is investigated rather than simply medicated. Risk rises with age, with a long history of irregular cycles, with PCOS, with obesity, with tamoxifen, and above all with any bleeding after the menopause.
Worth thinking about when periods have been heavy since the very first one, or when there is easy bruising, nosebleeds, bleeding after dental work, or a family history. Von Willebrand disease is the commonest. Guidelines recommend testing only in this specific pattern, not for everyone.
The cycle simply is not ovulating regularly, so the lining builds up unopposed and then sheds unpredictably. This is the usual explanation for irregular timing rather than heavy volume — and PCOS, thyroid disease, the years around the menopause and the years just after the first period are the common settings. See our page on PCOS and PCOD.
A structurally normal uterus that ovulates normally, but where the lining itself does not control its own bleeding properly. There is no test that proves this — it is what remains when everything else has been excluded, and it responds well to treatment.
Blood thinners, some hormonal contraceptives in the first months, a copper coil, and irregularly taken hormone tablets all cause abnormal bleeding. Always worth reviewing the medicine list before investigating anything else.
Rarer things that do not fit the other boxes — a caesarean scar niche, chronic infection of the lining, an arteriovenous malformation. Considered when the common causes have been excluded and the bleeding persists.
This classification exists for a reason worth knowing: before it, heavy bleeding with no obvious cause was labelled “hormonal imbalance” and treated the same way in everyone. Asking which of these nine is the single most useful question you can put to your doctor.
Most heavy bleeding is not urgent. These six are the exceptions.
Any bleeding at all, once periods have stopped for a full twelve months, needs assessing promptly. It is usually something benign — but it is the one symptom on this page that should not be watched, medicated or waited out.
Changing a fully soaked pad or tampon hourly for several hours in a row, or passing large clots repeatedly, is bleeding that needs to be seen quickly rather than booked for next month.
Not the same question as a heavy period. It points at the cervix, and the cervix needs looking at directly. This is what a Pap smear and cervical screening visit is for.
Occasional spotting mid-cycle is common and often harmless. Bleeding between periods that keeps happening month after month is a cavity question — polyp, fibroid or lining — and deserves a proper look inside rather than another course of tablets.
Dizziness on standing, breathlessness climbing stairs, palpitations or a level of tiredness that is new: these are anaemia until proven otherwise, and they change the urgency of everything else.
Any bleeding in a possible or confirmed early pregnancy is a separate and more urgent problem. Read bleeding in pregnancy, and be seen the same day.
And, just as usefully, which ones you do not.
This is the one test that guidelines recommend without exception for anyone with heavy menstrual bleeding. It tells you whether the bleeding has already cost you something, and it changes how urgently everything else needs to happen.
NICE advises against routinely checking ferritin in heavy menstrual bleeding. That advice was written for a population where baseline iron deficiency is uncommon. It does not travel to India. In the most recent National Family Health Survey, 57% of Indian women aged 15 to 49 were anaemic, up from 53% five years earlier — and iron stores run down long before haemoglobin falls. A normal haemoglobin here does not mean your iron is fine. We check it.
If your periods have been heavy since the very first one, or there is easy bruising, frequent nosebleeds, bleeding after dental work or a family history, testing for a bleeding disorder is appropriate. Otherwise it is not. This is a targeted test, not part of a panel.
Guidelines specifically advise against routine thyroid and hormone testing in heavy menstrual bleeding. They are worth doing when the story points there — irregular timing, symptoms of thyroid disease, features of PCOS — and not otherwise. A long hormone panel ordered reflexively usually generates more questions than answers.
Where a fibroid is large or the examination is difficult, an ultrasound is the right first look. Where the question is about the cavity — a polyp, a fibroid bulging inside, the lining itself — guidance points to hysteroscopy rather than a scan, because it sees directly and can treat in the same sitting. Scans are arranged by referral, and timed to the right point in your cycle: a scan done in the second half can hide a polyp completely.
A biopsy of the lining is indicated when bleeding persists between periods, when treatment has not worked, at 45 and over, and where there are risk factors such as PCOS, obesity or tamoxifen. Modern guidance is explicit that it should be taken at hysteroscopy, under vision, rather than blind. A blind sampling of a normal-feeling cavity misses a substantial share of polyps — which is why a normal biopsy result does not rule out a polyp.
If you take one thing from this section: a normal biopsy and a normal scan are not the same as a normal cavity. If bleeding continues after both, ask to be looked at, not re-tested.
In the order they should normally be considered.
Not a treatment for the bleeding, but the thing that changes how you feel soonest. Iron replacement runs alongside whatever else is decided, not after it. If your haemoglobin is very low, it also changes how quickly the rest needs to happen.
A tablet taken only on the heavy days. It does not contain hormones, does not affect fertility, and does not change your cycle — it just makes the bleeding lighter, by roughly a quarter to a half. The simplest first step for many women, and the one most often never offered.
Mefenamic acid and similar drugs reduce blood loss modestly and reduce period pain substantially. Useful where pain and heaviness travel together. Taken with food, and avoided if you have stomach ulcers or asthma triggered by these drugs.
The single most effective medical treatment for heavy bleeding, and what guidelines name as the first treatment to consider where the uterine cavity is normal or nearly so. It reduces menstrual blood loss dramatically, and in the Indian setting we plan on five years per device. Insertion and removal are both done at the clinic. See our full guide to Mirena as a treatment, not just contraception.
Useful when you also want contraception, or when the problem is irregular timing rather than sheer volume. Cyclical progestogens given only in the second half of the cycle are widely prescribed in India and are among the weaker options for heavy bleeding — worth knowing if that is all you have been offered.
If a polyp or a submucosal fibroid is the reason, removing it treats the bleeding properly. That is done at hysteroscopy — through the cervix, no cuts, day care — and it is the most under-offered option in Indian practice.
GnRH analogues switch off the cycle altogether. They work well but cause menopausal symptoms and bone loss, so they are used for a few months at a time — typically to correct severe anaemia and shrink a fibroid before an operation, not as a long-term answer.
Destroying the lining of the uterus, for women who have completed their family and whose cavity is normal. Effective, quick, and not a contraceptive — pregnancy after ablation is dangerous, so contraception continues.
Myomectomy removes fibroids and keeps the uterus. Hysterectomy is the last option on this list, not the first — genuinely right for some women, and worth a second opinion before consenting to it.
Two honest notes. First, the hormonal coil outperforms every tablet for heavy bleeding by a wide margin, and is still routinely skipped in favour of cyclical progestogens — if it has not been offered to you, ask why. Second, if surgery is being discussed, our article on heavy or irregular periods and when to consider surgery works through which operation matches which cause, and what recovery actually involves.
Treating the bleeding and ignoring the iron is half a job.
Ferritin is the store; haemoglobin is the balance in the current account. You can empty the store completely and still show a haemoglobin at the bottom of normal — while feeling exhausted, breathless on stairs, foggy and cold. That state has a name, iron deficiency without anaemia, and it responds to iron.
With 57% of women of reproductive age anaemic nationally, a woman with heavy periods here often starts from a deficit rather than arriving at one. This is precisely why the ferritin gets checked, and why iron replacement starts alongside treatment for the bleeding rather than waiting to see whether the bleeding settles.
Most women do not need infusions. What they need is the right dose, taken with vitamin C and away from tea, coffee, calcium and antacids, and continued for three months after the haemoglobin normalises so the store refills. Alternate-day dosing is often better tolerated and absorbed than daily. Intravenous iron is reserved for genuine intolerance, poor absorption, or a need to correct quickly — and IV medication can be given at the clinic where it is appropriate.
Women often agree to surgery while profoundly anaemic, at the point where everything feels unbearable. Correcting the iron first will not stop the bleeding — but it frequently changes how the choice looks, and it makes any operation that is still needed considerably safer.
Four steps, in this order.
How often, how long, how heavy, whether it is regular, whether it has always been like this, and what it stops you doing. This is not small talk — the pattern usually narrows the cause to two or three possibilities before any test is done.
A full blood count for everyone. Ferritin is checked here as well, which is a deliberate departure from UK guidance and the right call in India. Thyroid and clotting tests only where the story points at them, not as a routine panel.
Scans are arranged by referral and timed to the right part of your cycle, because a scan done at the wrong time can hide a polyp completely. Where the question is about the cavity, hysteroscopy answers it directly — that is done at hospital, as day care.
Medical options first where they are reasonable, with a clear review date rather than an open-ended prescription. If a procedure is the right answer, you will hear which one and why, and what happens if you do nothing.
Consultation, blood tests and IV medication where needed are done at the clinic. Scans are arranged by referral. Hysteroscopy and any surgery are carried out at hospital, as day care wherever possible.

Real stories from women whose lives we've had the privilege to be part of
"I had been struggling with PCOS for years: irregular periods, weight gain, constant fatigue. Dr. Anam took the time to truly understand my case. Within a few months my cycles became regular and I finally felt healthy again."
"The most compassionate doctor I have ever met. She never makes you feel rushed, always listens completely, and explains everything clearly. My whole family now comes to Dr. Anam."
"After two miscarriages I was terrified to try again. Dr. Anam identified the issue, treated it, and supported me through my entire third pregnancy. I now have a beautiful daughter, something I wasn't sure would ever happen."
"Dr. Anam handled my high-risk pregnancy with such care and expertise. Every visit felt reassuring. She explained everything clearly and was always available when I had concerns. My baby and I are both healthy and happy!"
"I visited Dr. Anam for recurrent UTIs I had suffered with for years. She finally found the root cause and gave me a long-term solution. Eight months with no recurrence."
"I was very nervous but Dr. Anam made the entire journey so comfortable. She is patient, thorough, and incredibly warm. I wouldn't trust anyone else with something so precious."

Learn more →Modern guidance defines heavy menstrual bleeding as blood loss that interferes with your physical, emotional, social or material quality of life. There is deliberately no number attached. The old threshold of 80 millilitres per period was abandoned because it is impractical to measure and described the problem poorly. Practical markers that correlate well with genuinely heavy loss are soaking through a pad or tampon within an hour repeatedly, passing clots larger than about two and a half centimetres, needing double protection, and getting up at night to change.
Eight days or fewer. Bleeding that regularly lasts longer than eight days is called prolonged menstrual bleeding and is worth investigating, even if the daily volume feels manageable.
A normal cycle arrives every 24 to 38 days, counting from the first day of one period to the first day of the next. Closer than 24 days is frequent bleeding; further apart than 38 days is infrequent bleeding. Both point somewhere different from heaviness.
Up to about seven to nine days between your shortest and your longest cycle over a year. Beyond that the cycle is classed as irregular, which usually raises a question about ovulation rather than about the uterus itself.
It is the international classification of causes of abnormal uterine bleeding. PALM covers the structural causes you can see: Polyp, Adenomyosis, Leiomyoma (fibroid) and Malignancy or hyperplasia. COEIN covers the non-structural ones: Coagulopathy, Ovulatory dysfunction, Endometrial, Iatrogenic and Not otherwise classified. It exists because before it, anything without an obvious cause was called a hormonal imbalance and treated identically in everyone.
Usually not. Cancer and pre-cancer are the least common of the nine causes in women of reproductive age. But they are the reason bleeding is investigated rather than simply medicated, and the risk rises with age, with years of irregular cycles, with PCOS, with obesity, with tamoxifen, and above all with any bleeding after the menopause.
It needs assessing promptly. Post-menopausal bleeding is benign in the large majority of women, but it is the one symptom on this page that should not be watched or medicated. Ask for an appointment within a week or two, and expect the lining of the uterus to be assessed at hysteroscopy rather than blind.
Occasional spotting mid-cycle is common and often harmless. Bleeding that keeps happening between periods points at the cavity of the uterus, most often a polyp or a fibroid bulging into it, and sometimes at the cervix. It is a looking problem rather than a medicating problem, and it responds poorly to more tablets.
Bleeding after sex is a cervical question rather than a heavy-periods question. The cervix needs examining directly and cervical screening needs to be up to date. It is not a symptom to sit on, even when everything else about your periods is normal.
Not always, and not always first. An ultrasound is the right first look where a fibroid is large or the examination is difficult. Where the question is specifically about the cavity, hysteroscopy is what guidance points to, because it sees directly and can treat in the same sitting. Scans are arranged by referral from the clinic and timed to the right part of your cycle, since a scan in the second half of the cycle can hide a polyp completely.
Not routinely. Guidance specifically advises against routine thyroid and hormone testing in heavy menstrual bleeding. They are worth doing where the story points there, particularly with irregular timing or features of PCOS, and not as a reflex panel.
In India, yes, and we check it. UK guidance advises against routine ferritin testing, but that advice was written for a population where baseline iron deficiency is uncommon. With 57% of Indian women of reproductive age anaemic, and iron stores emptying well before haemoglobin falls, a normal haemoglobin here does not mean your iron is fine.
Yes, and it is the commonest cause of iron deficiency anaemia in women of reproductive age. Tiredness out of proportion to your life, breathlessness on stairs, dizziness on standing, palpitations, cold hands and difficulty concentrating are the usual symptoms, and they often creep up slowly enough to be mistaken for normal.
Tablets are enough for most women, provided they are taken properly: the right dose, with vitamin C, away from tea, coffee, calcium and antacids, and continued for about three months after the haemoglobin normalises so the store refills. Alternate-day dosing is often better absorbed and better tolerated than daily. Intravenous iron is reserved for genuine intolerance, poor absorption or a need to correct quickly, and can be given at the clinic where it is appropriate.
Where the cavity of the uterus is normal or nearly so, guidelines name the hormonal coil as the first treatment to consider, because it reduces menstrual blood loss more than any tablet. If you would rather not have a coil, tranexamic acid, anti-inflammatory tablets, the combined pill or cyclical progestogens are all reasonable alternatives.
It is a non-hormonal tablet taken only on the heavy days. It does not affect fertility, does not alter your cycle, and does not contain hormones. It reduces blood loss by roughly a quarter to a half. It is avoided in women with a history of blood clots and is one of the most commonly under-offered treatments for heavy periods.
Substantially more than any tablet. In studies it reduces menstrual blood loss by the largest margin of any medical treatment, and many women end up with very light periods or none at all. It also treats period pain in many women. In the Indian setting we plan on five years per device.
They are widely prescribed in India and are among the weaker options for heaviness specifically. They are more useful when the problem is irregular timing rather than volume. If cyclical progestogens are all that has been offered and they have not worked, that is a reason to ask about the other options rather than to repeat the course.
When a specific structural cause has been identified and treating it will treat the bleeding, or when medical treatment has been genuinely tried and has not worked, in a woman whose symptoms are affecting her life. Surgery aimed at a cause somebody has actually identified works far better than surgery aimed at bleeding in general.
It destroys the lining of the uterus and is an option for women who have completed their family and whose uterine cavity is normal. It is quick and effective, but it is not a contraceptive and pregnancy after ablation is dangerous, so contraception continues afterwards.
Almost certainly not. Hysterectomy is the last option on the list, not the first. It is genuinely the right answer for some women, but there are seven things that come before it, and a second opinion before consenting to one is entirely reasonable and never taken as a slight.
Only partly, and it is no longer the recommended approach. A blind sampling of the cavity misses a substantial proportion of polyps and can leave a lesion behind entirely. Current guidance is that sampling should be done at hysteroscopy, under direct vision. A normal blind biopsy is not the same as a normal cavity.
It is worth considering if your periods have been heavy since the very first one, or if there is easy bruising, frequent nosebleeds, bleeding after dental work or a family history. Von Willebrand disease is the commonest. Testing is recommended for that specific pattern rather than for everyone with heavy periods.
Heavy bleeding together with genuinely severe pain, often in a woman in her late thirties or forties, is the classic picture of adenomyosis, where lining tissue grows into the muscle wall. It is frequently missed for years and frequently mislabelled as fibroids. Endometriosis is the other possibility worth naming.
Very possibly. PCOS is one of the commonest reasons for cycles that arrive unpredictably rather than heavily, because ovulation is not happening regularly and the lining builds up unopposed before shedding. Thyroid disease, the years around the menopause and the first years after periods start do the same thing.
It often is, because cycles stop ovulating reliably in the years before the menopause. But it is also the age at which the lining should be assessed rather than assumed, so perimenopause is a diagnosis to arrive at rather than to start with. At 45 and over, guidelines say the lining should be sampled where bleeding persists or treatment has not worked.
If you have bleeding after the menopause, bleeding after sex, bleeding in a possible pregnancy, or you are soaking through protection hourly and feeling faint, do not wait. Otherwise, two or three cycles tracked on paper is a useful thing to bring, and there is no harm in being seen before that if it is affecting your life.
A record of two or three cycles if you have it, with dates, duration and which days were genuinely heavy. Any previous scan or blood reports, including old ones, since comparing over time says more than a single result. And the names and doses of anything you have already tried, with how long you took it for.
Discuss your bleeding and plan treatment at either location. Open 7 days a week, including Sundays.
