The nose is a very important part of the body and it is loaded with blood vessels (vascular). It is placed in a vulnerable point as it overhangs on the face. As a result, any injury or trauma to the face can result nasal damage and bleeding. The bleeding may be plentiful, or just a minor problem. Nosebleeds can be dramatic and frightening.
Nosebleeds can happen suddenly when the nasal membranes dehydrated and get cracked. Nosebleed is very normal in dry climates, or during the winter season when the air is dry and warm because of household heaters. The occurrence of nosebleeds is high in the winter days because in cold climate the upper respiratory infections are more normal, as the temperature and humidity change more dramatically. And also changes from a harsh cold outer atmosphere to hot, dry, heated home results in drying and alterations in the nose make it more vulnerable to bleeding. Nosebleeds also take place in hot dry atmosphere with low humidity, or when there is an alteration in the seasons.
Luckily, most nosebleeds are not severe and easily can be managed at home, even though sometimes medical intervention may be required. Categorization of nosebleeds is based on from where they originate. There are two main types of nosebleeds:
Anterior nosebleeds
These types of nosebleeds are originated from the front of the nose and more than 90% of all nosebleeds are from this category. The bleeding in this type is typically begun from a blood vessel on the nasal septum. These nosebleeds are generally easy to control.
Posterior nosebleeds
These types of nosebleeds are originated from the back of the nose and are very rare in comparison to anterior nosebleeds. They tend to happen more frequently in elderly people. The bleeding mainly originates from an artery in the back portion of the nose. These nosebleeds are very complicated and need medical attention.
