Explanation

Heavy menstrual bleeding, also known as menorrhagia, is when a person loses more than 80 milliliters of blood during one menstrual cycle or has periods that last longer than 7 days. It can cause disruptions in daily activities and may lead to anemia, which is a condition where you don't have enough healthy red blood cells.

Signs of Heavy Menstrual Bleeding:

  1. Needing to change your pad or tampon every hour for several hours in a row.
  2. Needing to use double sanitary protection (like a pad and a tampon together).
  3. Waking up at night to change sanitary protection.
  4. Passing blood clots larger than a quarter.
  5. Having periods that last longer than a week.

When to See a Doctor:

  • If your periods are so heavy that they disrupt your daily life.
  • If you have symptoms of anemia, like tiredness or shortness of breath.
  • If you are concerned about the amount of bleeding.

It's important to consult a healthcare provider to discuss your symptoms and explore potential treatments. Early evaluation and management can help prevent complications and improve quality of life.
