Home > Patient & Family Resources > Health Library > Thrombocytopenia
Thrombocytopenia (say "throm-buh-sy-tuh-PEE-nee-uh") is a low number of platelets in the blood. Platelets are the cells that help blood clot. If you don't have enough of them, your blood can't clot well. That means it's harder to stop bleeding.
You may have low platelets because your bone marrow doesn't make them. Or your body's defenses (immune system) may destroy them.
Having an enlarged spleen can also reduce the number of platelets in your blood. This is because they can get trapped in the enlarged spleen.
Some diseases or medicines may also cause low platelets. But platelets may go back to normal levels if you treat the disease or stop using the medicine.
Treatment for low platelets starts with finding a cause that can be stopped. For example, your doctor may change a drug you take or treat an infection you have.
Treatment may include:
You may not need treatment if your problem is mild.
