Nose bleeds are pretty common and chances are, you have probably had one before. Occasional nose bleeds don't usually indicate a problem. The tiny blood vessels that line the inside of your nose are fragile, so it is no wonder that they can easily bleed. However, sometimes nose bleeds can become frequent. This may be an indication of a more serious problem.

Nose-picking is a common cause of nose bleeds.


One of the most common causes of frequent nose bleeds is dry air. Many people get nose bleeds more frequently in the winter, when the heat is on and the air is dryer. The dry air causes the membranes in the nose to dry out and sometimes crack. Certain regions of the country and world are also generally dryer than others. Arid, desert climates have much less humidity and homes may need to be supplemented with a humidifier to make the air moister.

Bad Habits

You might actually be the one responsible for frequent nose bleeds. Bad habits such as nose-picking can increase the chances of nose bleeds. Because the membrane and blood vessels inside the nose are so sensitive, any irritation caused by the picking can lead to bleeding. Frequent, forceful nose-blowing can also be a factor. People who are prone to allergies and other sources of chronic congestion may blow their nose too much or too hard, which can cause irritation.

Medical Conditions

There are a few medical conditions that may be responsible for frequent nose bleeds. The most common are sinusitis, colds, allergies and a deviated septum. These conditions can cause frequent congestion, which can irritate the membranes and blood vessels of the nose. Medications that are used to treat conditions like sinusitis, colds and allergies (such as decongestants and histamines) can also dry up the membranes of the nose.

Side Effects

Nose bleeds are sometimes a side effect of certain medications. Some medications such as warfarin, heparin and even common aspirin are known as anti-coagulants. They function by thinning the blood in order to control symptoms of diseases like blood clots and high blood pressure. However, the thinning of the blood may result in bleeding more easily and nose bleeds.

More Serious Problems

Occasionally, frequent nose bleeds can be a symptom of a more serious problem. They may be an indication of some type of bleeding disorder, which could also cause other symptoms like easily bleeding and bruising. Diseases such as hereditary hemorrhagic telangiectasia and even leukemia may cause nose bleeds. If you have nose bleeds, your doctor should rule out any chance that you may have one of these diseases.
