Key takeaways

  • A normal period lasts 3 to 7 days; bleeding consistently beyond 7 to 8 days is considered prolonged and worth evaluating.
  • Common causes include fibroids, adenomyosis, polyps, PCOS-related anovulation, thyroid problems, bleeding disorders, and a recently fitted copper IUD.
  • A sustained change from your own usual pattern matters more than any single number, even if it sits just inside the 'normal' range.
  • Prolonged or heavy bleeding is a leading cause of iron deficiency in Indian women, who already start from a very high anaemia baseline.
  • Effective treatment exists for almost everyone, from tranexamic acid to the hormonal IUS, and hysterectomy is rarely the first answer.
  • Soaking a pad every hour for several hours, fainting, severe pain, or any bleeding when pregnant or after menopause needs urgent care.

What Counts as a Prolonged Period?

Knowing what is normal makes it easier to recognise when your period has genuinely changed.

A normal period lasts 3 to 7 days, with a total blood loss of roughly 30 to 80 mL (this is almost never measured in real life, so self-assessment is what counts). Cycles run 21 to 35 days from the first day of one period to the first day of the next, and bleeding is usually heaviest in the first day or two before tapering. If your cycles fall outside this range, our guide to what irregular periods can mean is a useful companion.

A prolonged period lasts longer than 7 days; some guidelines use 8 days as the cutoff. The flow may be heavy throughout, light throughout, or variable, so a long period is not always a heavy one.

Heavy menstrual bleeding (HMB) is now defined functionally rather than by the old 80 mL rule. It means blood loss that interferes with your physical, social, emotional, or material quality of life. Practical signs include soaking through a pad or tampon every hour or two for several hours, needing double protection, flooding through to clothes or bedding, passing clots larger than a 50 paisa coin, and symptoms of anaemia. This is the definition used by NICE and FIGO.

Bleeding between periods (intermenstrual bleeding) is different from a prolonged period, though the line can blur when a long period trails into spotting. If this is your main pattern, see spotting between periods and, if it happens after intercourse, bleeding after sex.

What a meaningful change looks like. If your period has always been 5 days and is now consistently 9, that is worth checking even though 9 days sits near the top of normal. A sustained shift from your own baseline is significant. One longer period after a stressful month or an illness is usually normal variation and often settles on its own.

Why duration matters. Long or heavy bleeding steadily depletes iron. Indian women already carry one of the highest anaemia burdens in the world, so prolonged periods add to an existing problem rather than starting from zero, which is covered in detail below.

The PALM-COEIN framework. FOGSI, FIGO, and ACOG classify the causes of abnormal uterine bleeding as Polyp, Adenomyosis, Leiomyoma (fibroid), Malignancy and hyperplasia, Coagulopathy, Ovulatory dysfunction, Endometrial, Iatrogenic, and Not yet classified. The first four (PALM) are structural; the last five (COEIN) are non-structural. A good workup considers both.

Common Causes: Structural and Hormonal

Several conditions commonly lengthen periods in Indian women of reproductive age. Knowing the usual suspects helps make sense of the tests your doctor orders.

Uterine fibroids (leiomyomas) are benign muscle growths of the uterus, very common and more frequent with age. Submucosal fibroids, which bulge into the cavity, are especially likely to cause long, heavy periods, alongside pelvic pressure, urinary frequency, and sometimes fertility problems. They are diagnosed on pelvic ultrasound. See our full guide to uterine fibroids in India.

Adenomyosis is when endometrial tissue grows into the muscle wall of the uterus, making it bulky and tender. It typically causes heavy, prolonged, painful periods and is diagnosed on transvaginal ultrasound or MRI. Because it is easily confused with a related condition, our comparison of adenomyosis vs endometriosis is worth a read.

Endometrial and cervical polyps are benign growths. Endometrial polyps project into the uterine cavity and cause intermenstrual or prolonged bleeding; cervical polyps are seen on speculum examination and removed easily in an outpatient procedure.

PCOS-related anovulation. In PCOS, ovulation is often irregular or absent. Without the progesterone of a normal luteal phase, the lining keeps thickening under unopposed oestrogen and eventually breaks down in unpredictable, often prolonged, bleeds. See PCOS treatment options and, if you are unsure which label applies to you, PCOD vs PCOS.

Thyroid dysfunction. Both an underactive and overactive thyroid can disturb periods, with hypothyroidism more often causing heavier, longer bleeds. TSH and free T4 are part of the basic workup, and treating the thyroid usually settles the pattern within a few cycles. See thyroid and fertility for the wider picture.

Raised prolactin. High prolactin more often causes missed or scanty periods than long ones, but it sits in the differential and is easy to test. Read more in high prolactin.

Bleeding disorders. Von Willebrand disease, the most common inherited bleeding disorder, and other clotting problems can cause heavy, prolonged periods, often from the very first period. Clues include easy bruising, frequent nosebleeds, prolonged bleeding after dental work, and a family history. If your heavy bleeding has been lifelong since your first period, mention this to your doctor.

Copper IUD. Heavier and longer periods are an expected effect of the copper IUD, especially in the first 3 to 6 months, with roughly a 50 per cent increase in flow on average before it settles. See IUD cramps and bleeding and our copper IUD vs Mirena comparison.

New hormonal contraception. The first three months on a new pill, implant, injection, or hormonal IUS often bring breakthrough bleeding and occasional longer episodes that usually settle. See birth control pills in India.

Endometrial hyperplasia and cancer. These matter most in women over 40, and in those with chronic anovulation, obesity, PCOS, diabetes, tamoxifen use, or a family history, all of which involve prolonged unopposed oestrogen. Diagnosis needs an endometrial biopsy. If you are over 40 or postmenopausal with new bleeding, read the warning signs of endometrial cancer.

Pregnancy-related causes. Threatened or missed miscarriage and ectopic pregnancy can present as prolonged bleeding. A pregnancy test is always the first step in a sexually active woman with abnormal bleeding. See miscarriage types and recovery and ectopic pregnancy.

Medications. Anticoagulants, some antidepressants, antiplatelet drugs, and certain herbal preparations can affect bleeding. Review your full medication list with your gynaecologist.

How a Gynaecologist Works It Up: From History to Tests

FOGSI guidance for abnormal uterine bleeding follows a structured path: a detailed history, examination, and targeted tests.

History. Your doctor will ask about your menstrual pattern (age at first period, usual cycle length and duration, recent cycles in detail, clot size, soaking pattern, and whether you double up on protection), how the change started, associated symptoms (pain, spotting, post-coital bleeding, pressure or urinary symptoms), your sexual and contraceptive history, pregnancy history, anaemia symptoms (fatigue, breathlessness, dizziness, restless legs, craving ice), thyroid or PCOS clues, family history, medications, and lifestyle factors such as stress and recent weight change.

Examination. This includes BMI, a check for pallor, skin signs (acanthosis nigricans, hirsutism, bruising or petechiae), thyroid and breast examination, and an abdominal examination for masses.

Pelvic examination. A speculum examination looks at the cervix for polyps, ectropion, or suspicious lesions, and a bimanual examination assesses the size, mobility, and tenderness of the uterus and ovaries. A Pap smear or HPV test is done if cervical screening is due; if you are not up to date, see cervical cancer screening.

Blood tests. These typically include a pregnancy test, a complete blood count, and ferritin (the most sensitive marker of iron stores, often low before haemoglobin falls), plus TSH and free T4, prolactin if relevant, coagulation studies if a bleeding disorder is suspected, and hormone or metabolic panels for PCOS or perimenopause where indicated.

Pelvic ultrasound is the cornerstone of imaging. A transvaginal scan gives the best detail of the lining and cavity, while a transabdominal scan helps with a large uterus or masses. It is best done in the first half of the cycle when the lining is thin. If you find scan and lab reports confusing, our guide to understanding scans, labs and reports can help.

Saline infusion sonography (SIS) and hysteroscopy are second-line tests when the ultrasound needs clarifying or treatment is planned. SIS instils saline to outline the cavity and reveal polyps or submucosal fibroids; hysteroscopy lets the doctor look inside directly and can treat and biopsy at the same time.

Endometrial biopsy samples the lining for the lab. It is recommended for women over 40 to 45 with persistent abnormal bleeding, for those with risk factors for endometrial disease, for abnormal scan findings, and for any postmenopausal bleeding. An office Pipelle biopsy is a brief procedure costing roughly Rs 1,500 to 5,000 privately.

MRI is reserved for detailed assessment of adenomyosis, complex fibroids, or suspected cancer, at roughly Rs 5,000 to 15,000 privately.

Cost in India. A basic workup (pregnancy test, CBC, ferritin, TSH, prolactin, and a pelvic ultrasound) runs about Rs 2,000 to 5,000 at labs such as Dr Lal PathLabs, Metropolis, SRL, Thyrocare, and Apollo Diagnostics. Government tertiary hospitals offer most tests free or heavily subsidised, and PMJAY (Ayushman Bharat) covers eligible patients.

Medical Treatment: From Tranexamic Acid to the Hormonal IUS

Medical treatment is first-line for most women with prolonged or heavy bleeding, before any surgery is considered.

Tranexamic acid is an antifibrinolytic that cuts menstrual blood loss by about 30 to 50 per cent. The usual dose is 500 mg to 1 g three times a day for the first 3 to 5 days of the period, starting when bleeding begins. It is sold at any Indian pharmacy (Trapic, Pause, Texid) at Rs 10 to 30 a tablet. It does not regulate cycles or provide contraception, and it should be avoided if you have a history of blood clots.

NSAIDs such as mefenamic acid 500 mg three times daily, ibuprofen, or naproxen, taken for the first few days, reduce blood loss by about 20 to 30 per cent and ease cramps. Take them with food. Mefenamic acid is widely used in Indian practice; for more on cramp relief see painful periods.

Combined hormonal contraceptives (pills, patch, or ring) regulate cycles and reduce flow by about 30 to 50 per cent while also providing contraception. They are not suitable for everyone, particularly smokers over 35 and women with a history of clots or certain other conditions. See birth control pills in India.

Progestogen-only options include cyclical oral progestins (such as medroxyprogesterone acetate or norethisterone for part of each cycle) to regulate anovulatory bleeding, the progestogen-only pill, and the DMPA injection, which often leads to lighter periods or none over time.

The levonorgestrel intrauterine system (LNG-IUS) is the single most effective medical treatment for HMB, reducing blood loss by around 90 per cent over 6 to 12 months. Mirena (Rs 13,000 to 18,000) and the Indian-made Eloira (Rs 8,000 to 15,000) are the 52 mg options available here. It releases progestin directly into the uterus, thinning the lining; about 1 in 5 users have no periods at all by one year. FOGSI, ACOG, RCOG, and NICE all recommend it as first-line for HMB, including bleeding from fibroids that do not distort the cavity, adenomyosis, and ovulatory dysfunction. It is fitted in 5 to 15 minutes and also provides contraception. Our copper IUD vs Mirena guide explains the difference.

GnRH analogues (such as leuprolide or goserelin) create a temporary medical menopause and are used short-term, often before fibroid or adenomyosis surgery, at Rs 8,000 to 20,000 a month.

Iron supplementation is essential for almost any Indian woman with HMB, given the high background rate of iron deficiency. This is covered in detail in the next section.

The usual first step. FOGSI's typical starting plan is tranexamic acid plus an NSAID during periods, plus iron if you are anaemic. If that is not enough, or if you also want contraception, a combined pill or the LNG-IUS is added. Surgery is considered only if medical treatment fails or is unsuitable.

Surgical Treatment: When and What

Surgery is considered when medical treatment fails, is unsuitable, or is not preferred, or when there is a specific structural cause that surgery can fix. The right choice depends on the cause, your age, whether you want children, the severity of symptoms, and your own preferences.

Hysteroscopic procedures treat problems inside the cavity through the cervix, with no cuts. Hysteroscopic polypectomy removes polyps, and hysteroscopic myomectomy removes submucosal fibroids. Endometrial ablation destroys the lining and works well for HMB without a structural cause, but it is only for women who have completed their family, as pregnancy afterwards is uncommon and high-risk.

Myomectomy removes fibroids while keeping the uterus. It can be hysteroscopic, laparoscopic, or open depending on the fibroids, and it preserves fertility, so it is the usual choice for women who still want children. Fibroids can recur over the years.

Uterine artery embolisation (UAE) is a minimally invasive radiology procedure that blocks the blood supply to fibroids so they shrink. It is generally not recommended for women planning pregnancy and is available at major centres such as AIIMS, PGI, Apollo, Fortis, and Medanta.

Hysterectomy, removal of the uterus, is the definitive treatment for HMB. It is considered for women who have completed childbearing, when medical treatment has failed, or when there is significant pathology. It can be vaginal, laparoscopic, or open, and ovaries are usually kept in younger women to avoid surgical menopause. Recovery is 2 to 3 weeks (laparoscopic or vaginal) or 4 to 6 weeks (open). Private cost ranges from about Rs 60,000 to 2,50,000; government care is subsidised or covered under PMJAY.

If you may want children, conservative options (medical treatment, hysteroscopic procedures, and myomectomy) preserve fertility, and the LNG-IUS is fully reversible. If your family is complete, the full range, including ablation and hysterectomy, is open to you. Many women prefer to try the less invasive options first, while some choose the certainty of hysterectomy. Both are valid, and a frank discussion of risks, benefits, and alternatives with your gynaecologist is the heart of the decision.

Iron Deficiency and Anaemia in the Indian Context

Iron deficiency is extremely common in Indian women, and prolonged or heavy bleeding makes it worse. Treating the iron loss matters as much as treating the bleeding itself. For the full picture, see iron deficiency in Indian women.

The Indian baseline. NFHS-5 found that around 57 per cent of women aged 15 to 49 in India are anaemic, with iron deficiency the most common cause. This reflects predominantly plant-based diets with poorly absorbed iron, low vitamin C intake, frequent pregnancies and breastfeeding, and menstrual losses.

How HMB drives anaemia. A woman losing 80 mL of blood per period (the upper limit of normal) loses roughly 40 mg of iron each cycle. With prolonged or heavy bleeding, the monthly loss can outstrip what the diet replaces, slowly emptying iron stores (low ferritin), then lowering haemoglobin, and finally affecting energy, concentration, and exercise tolerance.

Symptoms to watch for include fatigue (often the first and most dismissed sign), breathlessness on exertion, dizziness, palpitations, pale skin, brittle or spoon-shaped nails, hair fall, restless legs, and a craving for ice or non-food items.

Diagnosis. A complete blood count showing haemoglobin below 12 g/dL (WHO criteria for non-pregnant women) defines anaemia; a low MCV points to iron deficiency, and ferritin is the most sensitive early marker.

Treatment. Oral iron (ferrous sulphate, fumarate, or bisglycinate) is first-line at Rs 30 to 200 a month. Take it with a vitamin C source such as orange, amla, or tomato, and away from tea, coffee, calcium, and antacids, which block absorption. Continue for at least three months after haemoglobin normalises to rebuild stores. The government's Anaemia Mukt Bharat programme provides iron-folic acid tablets free through PHCs and ASHA workers. IV iron (ferric carboxymaltose or iron sucrose) is used when oral iron is not tolerated, when anaemia is severe, or when losses are ongoing.

Diet. Iron-rich foods include eggs, fish, poultry, and meat (well-absorbed heme iron) and green leafy vegetables, legumes, jaggery, dates, nuts, and seeds (non-heme iron). Pairing vegetarian iron sources with vitamin C improves absorption, and cooking in iron utensils adds a little more.

Breaking the cycle. Untreated HMB keeps draining iron, and the resulting anaemia compounds the fatigue and disruption of heavy bleeding. Treating both at once is what restores how you feel.

When to See a Gynaecologist and What to Expect

Knowing when to seek care promptly helps you get the right diagnosis and treatment without unnecessary worry.

Seek urgent care if you have:

  • Soaking through a pad or tampon every hour or two for several hours in a row
  • Repeatedly passing large clots (bigger than a 50 paisa coin)
  • Bleeding with severe pain, fever, or foul-smelling discharge
  • Signs of major blood loss such as fainting, severe dizziness, breathlessness at rest, chest pain, or marked pallor
  • A positive pregnancy test with any abnormal bleeding (possible miscarriage or ectopic pregnancy)

Seek prompt care, within days to weeks, if you have:
  • Bleeding lasting more than 7 days over two or more cycles
  • Heavy bleeding that disrupts your daily life
  • A clear, sustained change from your usual pattern
  • Bleeding between periods or after sex
  • New or changing bleeding after age 40
  • Any bleeding after menopause
  • Symptoms suggesting anaemia

What to expect at the visit. The doctor will take the detailed history and do the examinations described above, then order initial tests such as a pregnancy test, CBC, ferritin, TSH, prolactin, and a pelvic ultrasound. They will explain the likely diagnosis, the treatment options and their pros and cons, the expected timeline, and the follow-up plan. Iron is started straight away if you are anaemic.

Follow-up is usually at 1 to 3 months to check your response, manage side effects, and repeat blood tests, with longer-term review for chronic conditions like PCOS, fibroids, or adenomyosis.

A second opinion is reasonable for any major decision, especially before surgery such as hysterectomy.

Where to go. Private gynaecology consultations cost about Rs 500 to 1,500 in most cities, with corporate hospitals (Apollo, Fortis, Manipal, Max, Medanta), private clinics, and FPAI offering services. Government secondary and tertiary centres, including AIIMS, PGI, and JIPMER, provide comprehensive care at subsidised or no cost, and telemedicine platforms can handle an initial assessment.

The emotional side. HMB takes a real toll, from the practical stress of planning around bleeding and dealing with leaks to anxiety, embarrassment, and the grinding fatigue of anaemia. This is worth naming and addressing alongside the medical treatment. Tracking your cycles, perhaps with a tool built around tracking without shame, gives your doctor a clear record and gives you back a sense of control.

Myths vs Facts

Frequently asked questions

How many days is a period considered too long?

A normal period lasts 3 to 7 days. Bleeding that consistently runs beyond 7 to 8 days is considered prolonged. A one-off long period after stress or illness is usually normal variation, but a sustained change over two or more cycles is worth getting checked.

Can stress make my period last longer?

Yes. Significant stress, illness, sudden weight change, or intense exercise can disrupt ovulation and lengthen or alter a period for a cycle or two. If the change persists, or comes with heavy bleeding or anaemia symptoms, see a gynaecologist rather than assuming it is only stress.

Is a long period a sign of cancer?

Most prolonged periods are caused by benign conditions such as fibroids, polyps, adenomyosis, hormonal imbalance, or a copper IUD. Cancer is uncommon but matters more after 40, and any bleeding after menopause needs prompt evaluation, including an endometrial biopsy. See our guide to endometrial cancer warning signs if this applies to you.

Will a long period cause anaemia?

It can. Prolonged or heavy bleeding steadily depletes iron, and Indian women already have a high anaemia baseline. Watch for fatigue, breathlessness, dizziness, hair fall, or ice cravings, and ask your doctor for a CBC and ferritin test. Iron supplementation alongside treating the bleeding usually restores your energy.

Do I need a scan if my period is just slightly longer than usual?

Not always. A single slightly longer period that settles often needs no investigation. But if the change is sustained, if bleeding is heavy, if there is pain or bleeding between periods, or if you are over 40, a pelvic ultrasound and basic blood tests are the standard first step.
