How to prevent nosebleeds?
Nosebleeds are common but rarely dangerous. They appear when the blood vessels which warm and humidify air in the nostrils become damaged. Young children and the elderly who may suffer from circulation problems are most at risk of nosebleeds.

How to prevent Nosebleeds?
The first step, upon consulting a physician, is determining the origin of the haemorrhage. Once that is done, there are two treatment options: cautery and anterior packing.
Cautery
Cauterization involves the use of a chemical solution, a small electrical discharge or a laser to burn the vessels responsible for the hemorrhage. This will prevent them from bleeding any further. Cauterization is used to treat those who suffer from frequent nosebleeds.
Anterior packing
This second method is used when the haemorrhage does not stop on its own after 20 minutes. The physician inserts a wick or cotton pack that will act like a sponge and will swell when it comes into contact with blood. By swelling, the pack will exert pressure on the blood vessel which will stop the bleeding.
In more serious cases where the above mentioned methods fail to prevent nosebleeds , more elaborate techniques may be undertaken but require hospitalization.
