Heavy Periods: Causes, Tests and Treatment Options
Heavy menstrual bleeding is bleeding that disrupts daily life or affects wellbeing. Learn when to seek urgent care, what tests may help and how to compare treatment options while protecting your priorities.

When is menstrual bleeding considered heavy?
Heavy menstrual bleeding is best understood by its effect on your life, not by a single pad count. Bleeding that interrupts work, school, sleep, travel, exercise or relationships deserves care. It may involve long periods, flooding, clots, leakage or needing to plan every activity around a toilet, and you do not have to wait until you feel weak to ask for help.
Track the impact as well as the bleeding
For a few cycles, note when bleeding starts and ends, how often you change products, leaks, clots, pain and missed activities. Changing a pad or tampon every 1–2 hours, bleeding for more than 7 days, needing two products together or bleeding through clothes can be useful signs, but no single count fits every product or person. Mention bleeding between periods or after sex separately.
Heavy bleeding can have several causes
Possible causes include fibroids, adenomyosis, polyps, ovulation or hormone changes, a bleeding disorder, medicines and, less commonly, changes in the lining of the uterus. Pregnancy-related bleeding has a different pathway. A clinician uses your history and symptoms to decide which causes need checking.
Know when bleeding needs urgent attention
Seek urgent care if bleeding is very heavy and you feel faint, dizzy, breathless, unusually weak, confused or have chest pain, or if you may be pregnant and are bleeding with severe pain. Use emergency care if you collapse or feel seriously unwell. Routine clinic assessment is still appropriate for ongoing heavy periods even without these warning signs.

What may happen at an appointment?
Assessment starts with your bleeding pattern, pain, daily-life impact, health history and goals. A clinician may recommend a blood count and, depending on symptoms, an ultrasound or hysteroscopy. You can ask what each test is intended to find, how invasive it is and what alternative could answer the question.
A blood count can check for anaemia
NICE recommends a full blood count for people with heavy menstrual bleeding alongside treatment. The blood test can identify anaemia, which may contribute to fatigue, weakness, dizziness or breathlessness. Local testing protocols in India may differ; ask which blood tests fit your symptoms and when results will be reviewed.
Imaging or hysteroscopy depends on the history
Ultrasound can assess the uterus and look for some causes such as larger fibroids. Hysteroscopy uses a thin camera to look inside the uterus and may be considered when symptoms suggest a polyp or another cavity problem. Ask about pain relief, consent, limits of the test and what happens if you prefer another option.
Mention bleeding since your first periods or a family history
If periods have always been very heavy, or you also have frequent nosebleeds, easy bruising or a family history of a bleeding condition, tell the clinician. A bleeding disorder may need consideration. Bring a list of medicines, supplements and contraception, and say if preserving fertility or keeping your uterus is important to you.
Treatment choices and shared decisions
Treatment depends on the likely cause, bleeding pattern, health conditions and your preferences. Options may include medicines, hormonal methods, treatment of a structural cause or a procedure. NICE guidance is a UK reference rather than an India-specific protocol; ask what is available locally and how each choice affects fertility, contraception and future periods.
Choose a plan around the outcome that matters to you
Tell the clinician whether your main goal is less bleeding, less pain, avoiding hormones, reliable contraception, future pregnancy or keeping your uterus. These priorities can change which options make sense. Ask how long a treatment trial usually takes and what to do if bleeding worsens or does not improve.
Ask about non-surgical and hormonal options
Depending on the cause, a clinician may discuss non-hormonal medicines, hormonal contraception or a hormone-releasing intrauterine system. Suitability depends on your health, medicines, pregnancy plans and local availability. Ask about likely benefits, side effects, cost and whether a treatment can be stopped or changed.
Understand procedures before consenting
If a polyp, fibroid or other uterine change is suspected, a procedure may be discussed. Endometrial ablation and hysterectomy have major implications for future pregnancy and should be explained in detail. Ask about uterus-preserving alternatives, surgical risks, recovery and whether another opinion is reasonable before planned surgery.
Heavy periods: frequently asked questions
How many pads per day count as heavy bleeding?
There is no single pad count that fits everyone because product size and absorbency vary. Needing to change a pad or tampon every 1–2 hours, bleeding longer than 7 days, using two products together, leaking through clothes or missing daily activities are useful signs to discuss with a clinician.
Can heavy periods cause anaemia?
Yes. Ongoing blood loss can contribute to iron deficiency or anaemia. A clinician may request a full blood count and discuss follow-up based on the result and your symptoms.
Will I need a scan or internal examination?
Not everyone needs the same tests. Your history and examination guide whether ultrasound, hysteroscopy, blood tests or another assessment could help. Ask why a test is recommended and discuss alternatives or a pause if an examination feels uncomfortable.
Does treating heavy periods mean I cannot have children?
Many treatment options do not end fertility, but some procedures affect the ability to carry a pregnancy. Tell the clinician about future pregnancy plans before choosing treatment and ask which options preserve fertility and the uterus.
Words you can use
Explain how heavy periods affect you
At a primary-care or gynaecology appointment
“My bleeding lasts [days] and affects [work, school, sleep, travel or other activity]. I also have [pain, clots, leakage, fatigue or dizziness]. Could we discuss a blood count and whether I need imaging or hysteroscopy? My priorities are [less bleeding, pain relief, future pregnancy, avoiding hormones or keeping my uterus].”
