If you bleed a lot during your menstrual cycle, you're not alone. Many women do. For some women, having heavy menstrual periods (also called menorrhagia) means passing large blood clots and changing sanitary pads and tampons often.
Several things can cause heavy periods. These may include:
Sometimes a cause for your bleeding can't be found.
In most cases, having heavy periods isn't serious. But it can affect your daily activities. In rare cases, heavy periods may mean that you have a more serious problem, such as an infection, an unknown pregnancy, or cancer.
When you have heavy periods, you may pass large blood clots and soak through your usual pads or tampons. You may also have periods that last longer than 7 days.
When you lose a lot of blood during your period, your iron levels can drop. This can cause anemia. Anemia can make you feel tired, weak, and short of breath.
Your doctor will ask about your symptoms and menstrual periods. You'll have a pelvic exam. To get a closer look, your doctor may also do an ultrasound or another type of test that shows the lining of your uterus. Sometimes a tiny sample (biopsy) of tissue is taken from your uterus to look for infection and abnormal cell changes.
Your doctor may also do blood tests to check for anemia or other problems.
Your doctor may recommend medicine or hormone treatments to slow or stop your periods. If these treatments don't help, you may need surgery to help control your menstrual bleeding.
If a growth, such as a polyp or fibroid, is causing your heavy periods, your doctor may recommend surgery or other treatments to remove the growth. This can help reduce or stop heavy bleeding.
Because blood loss from heavy periods can make you feel very tired and weak (anemic), your doctor may recommend that you take extra iron.

Based on the results of your pelvic exam, your doctor may also want to do:
Your doctor may also order blood tests to check for anemia. When you lose a lot of blood during your period, your iron levels may drop. This can make you feel tired, weak, and short of breath.

But if these treatments don't work, surgery may be needed to control your bleeding.
If you plan to become pregnant in the future, or if you're nearing the time when your periods will stop (menopause), you may want to try medicine first.
Hormone treatments that are used to help control heavy bleeding include:
Nonsteroidal anti-inflammatory drugs (NSAIDs), such as over-the-counter ibuprofen (Advil and Motrin, for example), also can help. They lower prostaglandins, which cause menstrual pain, and they reduce bleeding during your period. Be safe with medicines. Read and follow all instructions on the label.
Because blood loss from heavy menstrual periods can make you feel very tired and weak (anemic), your doctor may want you to take extra iron.
A medicine called tranexamic acid (such as Lysteda) is sometimes used for women who have bleeding that is heavier than normal. This medicine isn't a hormone. It prevents bleeding by helping blood to clot. Talk with your doctor to find out if this option is right for you.
If medicine doesn't help, or if you have a growth in your uterus (such as a polyp or fibroid), you may need surgery or another procedure to help control your menstrual bleeding.
