3. Frequent nosebleeds.
The nose is full of capillaries, the smallest of all blood vessels, and the lie close to the surface. Because of the density of capillaries and their position, the nose is prone to bleeding. As a result, those who have low platelets often experience frequent nosebleeds. Since platelets play a significant role in blood clotting, even a minor injury in the nose can spark a major nosebleed; nose-blowing, a common cold, or any other irritation can spark a nosebleed in individuals with low platelet levels.
Often, these nosebleeds seem to occur out of nowhere and for no reason. While there are a variety of reasons why someone might experience chronic nosebleeds, such as exposure to dry air, chronic sinusitis, allergies, and hemophilia, another type of blood disorder, low platelet levels are also a common cause. If you are experiencing unexplained nose bleeds, see your medical doctor.
