What causes nosebleeds?

Many possibilities: The most common source of a nose bleed is from the front/ bottom part of the nasal septum. This is a vascular area and some people have prominent blood vessels in this area. The blood vessels may break with a nose blow, dryness, or picking at this area. But there are other more serious causes such as hypertension, growth and even a malignancy. See an ENT doctor.

Variety of issues: Lack of humidity such as in winter time with heat turned on. This can dry mucosa and cause nose bleeds. Low platelets as in certain blood diseases can also cause nose bleeds. Any issue that raises blood pressure. As you can see there are a variety of causes.
Dr. David Astrachan

Superficial vessels: 95% of nosebleeds occur from the front of the nose. Blood vessels can be superficial in that area and easily traumatized. This then can lead to bleeding. Bleeding is usually worse when noses are irritated either from an upper respiratory tract infection or allergies. Some people have bleeding disorders which can also make bleeding worse. If nosebleeds are a problem for you you should see an ENT doctor for an evaluation.

Causes: Nose bleed reasons: nasal congestion or nasal dryness, ^ blood pressure, excessive use of decongestants, being at ^ altitude, trauma to nose, nose picking, or blowing the nose hard. Bacterial ; viral infections can ^ risk as well as bleeding disorders. Recurrent nose bleeds may be due to broken vessel in the nose. Alcohol / Cocaine abuse can cause nose bleeds, as can tumors.

Does the flu cause nosebleeds?

No: But a cold virus could. If you have nasal congestion as part of this, it may not be a flu virus. People get nosebleeds this time of year from allergies, so it's not impossible to have a nosebleed and havethe flu, i just don't think the two are really connected.
A member asked:

Can anemia cause nosebleeds?

2 doctor answers3 doctors weighed in
Dr. Dan Fisher

No: Anemia itself does not cause nosebleeds. Anemia is a sign of an underlying disease. The underlying disease which produces anemia may also cause disorders of clotting or of platelet number or activation. Those processes may indeed cause bleeding including nosebleeds.
