Nosebleeds can be a contributor to iron deficiency anemia. Actually, any prolonged or frequent bleeding can cause iron deficiency in your blood. This includes internal bleeding, exceptionally heavy menstrual bleeding, and nosebleeds.
So while anemia won't cause a nosebleed, they can cause anemia. Headaches and pale skin that accompany your frequent or heavy nosebleeds may be a sign that you are becoming anemic from the blood loss.
If you believe this is happening to you, it is very important that you contact your doctor right away so that it can be addressed before it becomes more serious. One common way doctors often recommend to combat this is to have you take iron supplements, although every case is different and a medical professional should be contacted.
