Periods can vary from woman to woman. However, very heavy or prolonged menstrual bleeding should not always be considered normal, especially when it affects daily activities or causes weakness, dizziness, or other symptoms.
Heavy menstrual bleeding may include needing to change sanitary products very frequently, periods lasting more than seven days, passing large blood clots or bleeding that interferes with work, exercise, sleep or everyday activities.
Several conditions can cause heavy periods, including fibroids, adenomyosis, endometriosis, hormonal changes, bleeding disorders and certain medicines. Consulting a gynaecologist can help identify the possible cause and determine whether treatment is needed.
What Is Considered Heavy Menstrual Bleeding?
Heavy menstrual bleeding means menstrual bleeding that is unusually heavy or lasts long enough to affect your health or quality of life.
You may have heavy menstrual bleeding if you:
- Need to change your pad or tampon every 1–2 hours.
- Have periods that regularly last more than 7 days.
- Pass large blood clots.
- Bleed through your clothes or bedding.
- Need to wake up at night to change your menstrual product.
- Avoid work, exercise, or social activities because of heavy bleeding.
- Feel unusually tired, weak, dizzy, or short of breath.
A significant change from your usual menstrual pattern is also worth discussing with a healthcare professional.
What Causes Heavy Menstrual Bleeding?
Heavy periods can have different causes. Common causes include:
- Fibroids
Fibroids are non-cancerous growths in or around the uterus. Depending on their size and location, they may cause heavy or painful periods. - Adenomyosis
Adenomyosis occurs when tissue similar to the uterine lining grows into the muscular wall of the uterus. It can cause heavy and painful periods. - Endometriosis
Endometriosis occurs when tissue similar to the uterine lining grows outside the uterus. It can cause painful periods and pelvic pain and may be associated with changes in menstrual bleeding. - Hormonal Changes
Hormonal changes or problems with ovulation can affect the menstrual cycle and may lead to irregular or heavy bleeding. - Bleeding Disorders
Some bleeding disorders can affect normal blood clotting and contribute to heavy menstrual bleeding. - Certain Medicines
Medicines such as anticoagulants may increase bleeding. If your periods become heavier after starting a medicine, discuss this with your doctor rather than stopping the medicine yourself.
When Should You Consult a Gynaecologist?
Consider consulting a gynaecologist if:
- 1. You Need to Change Your Pad Very Frequently
Regularly soaking through a pad or tampon every one to two hours may indicate unusually heavy bleeding.
- Your Period Lasts More Than 7 Days
Bleeding that continues for more than a week, particularly when it is heavy, may require evaluation.
- You Pass Large Blood Clots
Occasional small clots can occur during periods. Repeatedly passing large clots along with heavy bleeding should be discussed with a doctor.
- Heavy Periods Affect Your Daily Life
If you avoid work, exercise, travel or social activities because of your bleeding, it may be time to seek medical advice.
- You Feel Weak, Dizzy or Short of Breath
Repeated heavy bleeding can contribute to iron deficiency or anaemia, which may cause tiredness, weakness, dizziness or shortness of breath.
- Your Periods Suddenly Become Heavier
A noticeable and persistent change in your usual menstrual pattern can have several possible causes and should be evaluated.
- You Bleed Between Periods or After Sex
Bleeding between periods or after sexual intercourse is different from normal menstrual bleeding and should be assessed by a healthcare professional.
When Is Heavy Menstrual Bleeding an Emergency?
Seek urgent medical attention if very heavy vaginal bleeding occurs with:
- Fainting or feeling like you may faint
- Severe dizziness or weakness
- Difficulty breathing
- Severe abdominal or pelvic pain
- Feeling severely unwell
If pregnancy is possible and you have unusual vaginal bleeding with abdominal or pelvic pain, seek prompt medical evaluation.
How Is Heavy Menstrual Bleeding Diagnosed?
A gynaecologist will usually ask about your menstrual pattern, symptoms, medical history and medicines.
You may be asked about:
- How long your periods last
- How frequently you change menstrual products
- Whether you pass blood clots
- Pelvic or period pain
- Bleeding between periods or after sex
- Previous gynaecological conditions
Depending on your symptoms, your doctor may recommend blood tests, pregnancy testing when appropriate, a pelvic examination, or an ultrasound. Additional tests may be advised if a specific condition is suspected.
Keeping a record of your periods, bleeding pattern and symptoms before your appointment can also be helpful.
How Is Heavy Menstrual Bleeding Treated?
Treatment depends on the underlying cause, severity of bleeding, overall health, and individual reproductive goals.
Depending on the diagnosis, treatment may include:
- Medicines to reduce bleeding or manage symptoms
- Hormonal treatment to regulate menstrual bleeding
- Treatment for fibroids, polyps or other uterine conditions
- Minimally invasive procedures, such as hysteroscopy or laparoscopy, when clinically appropriate
- Surgery in selected cases
Your gynaecologist will recommend treatment based on your individual condition.
Heavy Menstrual Bleeding and Anemia
Persistent heavy menstrual bleeding can lead to iron deficiency or anaemia. This may cause tiredness, weakness, dizziness or shortness of breath.
If you experience these symptoms with heavy periods, speak with a healthcare professional. Your doctor may recommend blood tests to check for anaemia or iron deficiency.
