What does it mean if you get bloody noses a lot?

Frequent bloody noses are typically due to three causes: * Hypertension or high blood pressure. * Problems with clotting factors, resultant from pathology or from "blood-thinning" medications such as Plavix or Coumadin. * Problems with the tissues and processes in the nose and related areas. The first factor relates to cardiac problems and, if you aren't experiencing cardiac issues, are unlikley causes. Blood dysgracias that interfere with clotting factors can be diagosed serologically, but are not the usual culprit. Most often, bloody noses in the otherwise healthy, are the result of damage to the nasopharyngeal tissues, either emergent or chronic. This sort of damage can come from dehydrtation of these tissues (dry air, exposure to lots of dust, etc.), over-use of nasal decongestants -- especially aerosols (both quite common), deviation of the septum, or scarring. I'd have my doc take a look in-office with a nasopharyngascope and see if he can identify what's wrong, before proceeding to more serious measures.
