What is the cause for bleeding from the nose?
Nosebleeds can happen for a wide range of reasons such as irritation of the arterioles, dehydration of the nasal membrane, medications, nasal sprays, infections, high blood pressure, liver disorders vitamin deficiency or blood disorders.
The nose contains several tiny blood vessels called arterioles that may get irritated and rupture with ease. Bleeding from the nose is more commonly seen in children between 2 and 10 years of age, and in adults of 50-80 years of age. Most nosebleeds are common in dry climatic conditions or during the winter season as heated air indoors may cause dehydration of the nasal membranes. Dryness of these membranes may cause crusting and bleeding from the nasal septum. Certain medications and nasal sprays or a viral infection may also lead to bleeding from the nose. Rarely, nosebleed may suggest an inherited abnormality of small blood vessels, high blood pressure, liver disorder, vitamin deficiency, and blood disorders.
When you experience a nosebleed, remove any clotted blood out of the nose by a gentle blowing action. Bleeding can be stopped by pinching the soft parts of your nose using the thumb and index finger for about 15 minutes. Do not pack any cotton or gauze piece inside the nostrils. Avoid rubbing or blowing your nose for few days until healing is complete. Dryness of the nasal membranes may be prevented by applying a thin coat of petroleum jelly or antibiotic ointment on the middle portion of the nasal septum.
