Doctor, explain nosebleeds.
Insight into care and prevention of epistaxis (nosebleeds)
What causes a nosebleed?
Most nosebleeds (epistaxis) are mere nuisances. But some are quite frightening, and a few are even life threatening. Physicians classify nosebleeds into two different types.
Anterior nosebleed: Most nosebleeds begin in the lower part of the septum, the semi-rigid wall that separates the two nostrils of the nose. The septum contains blood vessels that can be broken by a blow to the nose or the edge of a sharp fingernail. This type of nosebleed comes from the front of the nose and begins with a flow of blood out one nostril when the patient is sitting or standing.
Posterior nosebleed: More rarely, a nosebleed can begin high and deep within the nose and flow down the back of the mouth and throat even if the patient is sitting or standing.
Which type of nosebleed did I have?
Obviously, when the patient is lying down, even anterior (front of nasal cavity) nosebleeds may seem to flow posteriorly, especially if the patient is coughing or blowing his nose.
It is important to try to make the distinction since posterior (back of nasal cavity) nosebleeds are often more severe and almost always require a physician's care. Posterior nosebleeds are more likely to occur in older people, persons with high blood pressure, and in cases of injury to the nose or face.
Anterior nosebleeds are common in dry climates or during the winter months when heated, dry indoor air dehydrates the nasal membranes. Dryness may result in crusting, cracking, and bleeding. This can be prevented if you place a bit of lubricating cream or ointment about the size of a pea on the end of your fingertip and then rub it inside the nose, especially on the middle portion of the nose (the septum).
What are my treatment options?
Many physicians suggest any of the following lubricating creams or ointments. They can all be purchased without a prescription: Bacitracin, A and D Ointment, Eucerin, Polysporin, and Vaseline. Up to three applications a day may be needed, but usually every night at bedtime is enough. A saline nasal spray will also moisten dry nasal membranes.
If the nosebleeds persist, you should see your doctor. Using an endoscope, a tube with a light for seeing inside the nose, your physician may find a problem within the nose that can be fixed. He or she may recommend cauterization (sealing) of the blood vessel that is causing the trouble.
What about rebleeding?
To prevent rebleeding after initial bleeding has stopped:
