“What is the main cause of a nosebleed?”

The lining of your nose contains many tiny blood vessels that lie close to the surface and are easily irritated.

The two most common causes of nosebleeds are:

1. Dry air — your nasal membranes may dry out, making them more susceptible to bleeding
2. Nose picking

Most common nosebleed is due to picking at the nose. However, people with nasal allergy may have spontaneous nose bleeding easily. Low humidity in the environment making the nasal mucosa fragile and thus nose bleeding. Some people have genetic problem like von Williebrand disease or other bleeding disorders. Other less common diseases are like nasopharyngeal tumors. Please seek an appointment with your child's pediatrician for further evaluation.

The most common cause for nosebleed in children is nose picking. Other things include; change in weather such as dry weather and change in humidity. Some nasal sprays even those used to treat nasal congestion and allergies such as steroids sprays. Less commonly family history of nose bleeds and thin lining of the mucosa and much much less likely bleeds related to hematologic diseases.
Treatment consist of of course avoiding picking the nose and use Vaseline or saline gel to both nostrils especially before bed. If nose bleeds continue pls see ENT!

Most nosebleeds occur when the nasal mucosa gets too dried out such as with too much heat. Use saline mist in the nose several times a day. Avoid aspirin or motrin products. Make sure he does not pick at his nose
