Most women have a sense of what their period normally looks like.
How many days it last?
How heavy the flow is?
How many sanitary pads,tampons,how many times they reinsert the menstrual cup.
Heavy menstrual bleeding is one of the most common reasons women visit a gynaecologist in India. You should not ignore heavy menstrual bleeding or assume it is normal. In many cases, there is a clear cause and treatment.Having to quietly suffer and assume its normal reduces the quality of life and disrupts the regular lifestyle.
What Counts as Heavy Menstrual Bleeding?
Medically, heavy menstrual bleeding, also called menorrhagia, is defined as losing more than 80 ml of blood per period. While it is not practical to measure blood loss during periods in millilitres, more useful signs to look for include:
● Needing to change a fully soaked pad or tampon every hour or two for several hours in a row.
● Passing blood clots larger than 2.5 cm across.
● Bleeding that lasts more than seven days.
● Needing to use double protection, like a pad and a tampon together, just to manage the flow.
● Bleeding that leaks through and soils clothes or bedsheets despite using protection.
● Having to plan activities around the period because the flow is unpredictable or too heavy to manage.
One or two heavy days in a period is common for many women. But it becomes a concern when this pattern is consistent, worsens over time, or significantly affects quality of life.
Common Causes of Heavy Periods
Excessive period bleeding does not have just one cause or definition. There are multiple possible causes, so finding the specific reason is crucial for choosing the appropriate treatment.
Uterine fibroids
Fibroids are non-cancerous growths in or on the uterus. They are extremely common, especially in women in their thirties and forties, and are one of the most frequent causes of heavy periods. Fibroids inside or just beneath the uterine lining (submucosal fibroids) tend to cause the heaviest bleeding. They can also cause longer periods and a feeling of pelvic heaviness or pressure.
Adenomyosis
In adenomyosis, the tissue that normally lines the inside of the uterus grows into the muscular wall of the uterus. This causes the uterus to enlarge and periods to become heavier, longer, and more painful. It is more common in women who have had children and tends to worsen with age. It is often underdiagnosed because it can only be confirmed on MRI or during surgery.
Endometriosis
Endometriosis is a condition where tissue (similar to the uterine lining) grows outside the uterus, on the ovaries, fallopian tubes, bladder, or bowel. While it is more commonly associated with painful periods, it can also cause heavy bleeding. This occurs because the endometrial-like tissue outside the uterus still responds to monthly hormonal changes, leading to bleeding in areas where it normally wouldn’t happen. Women with endometriosis often have both heavy and painful periods.
Uterine polyps
Polyps are small and soft growths on the inner lining of the uterus. They are usually benign but can cause spotting between periods, heavy or irregular bleeding, and bleeding after sex. They are easily diagnosed on ultrasound or hysteroscopy and can be removed through a simple procedure.
Hormonal imbalances
When estrogen and progesterone are out of balance, the uterine lining can build up more than usual and shed heavily during the period. This is common in women with PCOS, in teenagers whose menstrual cycles have not yet become regular, and in women approaching menopause when ovulation becomes irregular. Thyroid disorders can also cause changes in period flow and are very common in Indian women.
Intrauterine Device (IUD)
The copper IUD, which is a non-hormonal contraceptive, is a known cause of heavier periods, especially in the first few months after insertion. If your periods have become heavier after getting a copper IUD, the device is probably the cause.
Bleeding disorders
Some women have an underlying blood-clotting disorder that makes it harder for bleeding to stop normally. Von Willebrand disease is the most common of these and is often not diagnosed until a woman presents with heavy periods. If other women in your family have had heavy periods or bleeding problems, this pattern may point toward an underlying bleeding disorder.
Pelvic inflammatory disease (PID)
Infections in the reproductive organs, often from sexually transmitted infections, can cause inflammation and changes to the uterine lining that result in heavier periods. PID can also cause pelvic pain and an unusual discharge alongside the heavy bleeding.
Endometrial hyperplasia and cancer
In a small number of cases, particularly in women over 40 or after menopause, heavy or irregular bleeding can be a sign of abnormal thickening of the uterine lining or, rarely, endometrial cancer. That’s why it’s important to have persistent heavy bleeding checked by a doctor instead of assuming it’s harmless.
Menorrhagia Symptoms to Watch For
Beyond the heavy bleeding, certain menorrhagia symptoms alongside heavy periods point towards specific causes and are important to mention to your gynaecologist:
● Severe cramping alongside heavy flow can suggest adenomyosis or fibroids.
● Pelvic pressure or a feeling of fullness is common with larger fibroids.
● Fatigue and breathlessness may indicate anaemia due to blood loss.
● Irregular periods or bleeding between periods suggest a hormonal cause or polyps.
● Pain during sex can accompany adenomyosis, fibroids, or endometriosis.
● Bleeding after menopause always needs prompt investigation.
When to See a Gynaecologist
See a gynaecologist if:
● Your periods have become noticeably heavier than they used to be.
● You are regularly soaking through a pad or tampon in an hour or less.
● Periods are lasting longer than seven days.
● You are passing large clots.
● The bleeding is affecting your work, sleep, or daily activities.
● You feel persistently tired or breathless around your period.
● You have bleeding between periods or after sex.
● You are over 40, and your period pattern has changed significantly.
● Surgery for fibroids, polyps, or adenomyosis where medical treatment has not worked or is not suitable; options range from hysteroscopic removal of polyps and fibroids to endometrial ablation to hysterectomy in severe cases.
Conclusion
Heavy periods are common, but they are not something to simply endure. In most cases, there is a cause and a treatment that works. If your periods are affecting your daily life, see a gynaecologist. A blood test and an ultrasound are usually enough to start getting answers.

Heavy menstrual bleeding has several possible causes, like uterine fibroids, adenomyosis, endometriosis, polyps, hormonal imbalances, thyroid disorders, a copper IUD, or bleeding disorders. Fibroids and hormonal causes related to PCOS are among the most common. A pelvic ultrasound and blood tests are usually the starting point for finding the cause.
How much bleeding is considered heavy?
Doctors define heavy menstrual bleeding as losing over 80 mL of blood per period. In real life, this often looks like needing to change a fully soaked tampon or pad every one to two hours for several hours, passing clots larger than 2.5 cm, bleeding for more than seven days, or needing to use double protection. If your period interferes with work, sleep, or daily life, it’s a good idea to get it checked—even if you’re unsure about the exact amount of blood loss.
Can heavy periods cause anaemia?
Yes, and this is very common in India. Menorrhagia symptoms include fatigue, breathlessness, dizziness, and difficulty concentrating, all of which are signs of iron-deficiency anaemia from ongoing blood loss. Many women have normalised this exhaustion without realising anaemia is behind it. A blood test checking haemoglobin and ferritin will confirm it. Treating the anaemia with iron supplements alongside addressing the cause of excessive period bleeding is essential.
What causes heavy bleeding during periods?
Causes of heavy periods include uterine fibroids, adenomyosis, endometriosis, uterine polyps, hormonal imbalances from PCOS or thyroid disorders, a copper IUD, and blood-clotting disorders like Von Willebrand disease. In older women, endometrial hyperplasia is also a cause that needs to be ruled out. Finding the specific cause requires a gynaecologist review, blood tests, and usually a pelvic ultrasound.
