A bloody nose is a certain medical condition characterized by the draining of blood from either one or both nostrils at the same time. The professional medical term used to describe this medical condition is epistaxis. This condition may affect any person from any age group, but still it affects the children much more than it affects adult persons. Nosebleeds can only rarely be considered as serious medical condition, but they still need to be treated on time, especially in those who suffer from underlying medical conditions which may be related to blood clotting problems.
Nose is a very vascular area of the human body which means that its inner lining is covered in a large number of arteries and veins. A blood nose can be triggered for no particular reason. Sometimes it can be triggered simply by blowing of the nose a bit too vigorously. Any type of damage or injury to the aforementioned blood vessels can be enough to trigger the drainage of blood from the nose. Other common causes of nosebleed include sudden trauma or blow to the face or nose, infections in the nasal lining, nose picking, dryness of the nasal membranes and numerous different types of allergies.
