What “heavy” means in practice
Heavy menstrual bleeding is bleeding that interferes with physical, social or emotional quality of life. Flooding, frequent product changes, bleeding through clothes or bedding, large clots, or prolonged bleeding are useful details to report.
Iron deficiency can develop
Ongoing blood loss can reduce iron stores and lead to anaemia. Tiredness, breathlessness, palpitations, headaches, pallor, restless legs or hair shedding can occur, but symptoms alone do not confirm the diagnosis.
Treat the cause as well as the iron
Blood tests may assess anaemia, while history and examination guide whether other investigation is needed. Iron tablets can cause digestive effects and excessive iron can be harmful, so supplementation should match clinical advice.
Useful information to track
- Cycle length, bleeding days and practical impact
- Flooding, clots, pain or bleeding between periods
- Fatigue, breathlessness, palpitations or dizziness
- Blood count, ferritin if measured, treatment and repeat-test date
When to seek help
Very heavy bleeding with faintness, severe weakness, chest pain, breathlessness at rest or possible pregnancy needs urgent assessment.
