Although nosebleeds are generally harmless and easily controlled, it may look like a large amount of blood is coming from your nose. Most nosebleeds are easy to stop. Sometimes you need a place to turn to for advice and support. Hence, the reason for the creation of the Nosebleed Support website.
The medical term for a nosebleed is epistaxis. It is also known as a nasal hemorrhage. The human nose is rich in blood vessels. Because of the position of the nose – right in the middle of the face – and all its blood vessels, most of us will have had at least one nosebleed at some time during our lives.
Nosebleeds are seldom a cause for alarm but are a concern in children and can be life threatening in rare cases both in children and adults. Children between the ages of 2 and 10 and adults between 50 and 80 years seem to be most susceptible to nosebleeds. To the general population, nosebleeds are merely a nuisance. Only a small percentage of the population will require more clinical treatment than self treatment.
Spontaneous nosebleeds are fairly common, especially in children. When the mucous membrane inside the nose dries, crusts, or cracks and is then picked, it is likely to bleed.
Any minor injury to the face can also cause the nose to bleed.
Nosebleeds are also common in people taking anti-coagulants (blood-thinning medications, such as Aspirin), as well as in older people whose blood may take longer to clot. If the patient is taking anti-coagulants, has hypertension (high blood pressure), or a blood-clotting disorder, the bleeding may be harder to stop and could last over 20 minutes.
There are two types of nosebleeds, Anterior and Posterior. 90% of nosebleeds occur anteriorly.
The bleeding originates from the lower nasal septum (nasal partition – the wall between the two nostrils). This part of the nose contains many delicate blood vessels that receive blood from the carotid arteries, two principal arteries in the front of the neck that supply blood to the head and neck. The slightest knock or bump can cause these vessels to bleed. Anterior nosebleeds are easily treated at home. This is likely to be the type of nosebleed that you have.
The bleeding originates further back and higher up the nose where artery branches supply blood to the nose, which is why it is heavier. Posterior nosebleeds are often more serious than anterior nosebleeds and may require medical attention.
The main symptom of a nosebleed is blood coming out of the nose, which can range from light to heavy. The blood comes out of either nostril.
If the nosebleed occurs while you are lying down, you may feel liquid in the back of your throat before the blood actually comes out of your nose. Do not swallow the blood as it could cause you to become nauseous and vomit.
Severe nosebleeds require immediate medical attention. Things to watch for include heavy bleeding, palpitations (an irregular heartbeat), swallowing large amounts of blood that cause you to vomit, shortness of breath, or turning pale.
