The short explanation
It is a good question to raise with a doctor. Heavy periods since the first period, along with easy bruising, bleeding gums and a family history of heavy bleeding, can sometimes point to an inherited bleeding disorder. The most common one is von Willebrand disease, where the blood does not clot as well as usual. It is often missed in women because heavy periods are assumed to be normal. Bleeding disorders are not rare among women with lifelong heavy periods, and finding one matters. It changes how heavy periods are treated, and it is important to know before any surgery, dental work or childbirth. Other causes of heavy periods are possible too, so the doctor will look at the full picture.
What depends on your situation
The parts of this that change from woman to woman. Uncertainty is stated, not hidden.
- Other clues doctors ask about include nosebleeds that last a long time, heavy bleeding after dental extraction or surgery, and bleeding after childbirth.
- Tests usually start with a blood count and basic clotting tests. Specific tests for von Willebrand disease may need a referral to a haematologist, because ordinary tests can be normal.
- Treatment for heavy periods linked to a bleeding disorder often involves a gynaecologist and a haematologist working together.
What this answer cannot determine
The boundary of online education. These need a clinician who can see you.
- This answer cannot tell whether you have a bleeding disorder. That needs specific blood tests and a specialist assessment.
Questions for your clinician
Take these with you. You can add any of them to an appointment card.
- Could I have a bleeding disorder like von Willebrand disease?
- Which blood tests should be done, and do I need a haematologist?
- How would this change treatment for my heavy periods?
- Should other women in my family be tested?
When to seek help
Clinician-approved guidance for this topic. When in doubt, being seen is never the wrong choice.
Emergency — call 112 now
- Call 112 or go to the nearest emergency department if bleeding will not stop, you feel faint, or you are breathless at rest.
Get help the same day
- Get care the same day if you are soaking pads every hour or have a nosebleed that will not stop.
Raise it at a routine appointment
- Book an appointment to discuss testing for a bleeding disorder, especially before any planned surgery, dental extraction or pregnancy.
