A nosebleed, or epistaxis, is bleeding from the nose resulting from the rupture of a blood vessel in the nasal lining. It is a normal occurrence affecting people of all ages. Particularly susceptible to bleeding, the nasal cavity features a rich network of blood vessels. Usually speaking, nosebleeds fall into two categories: anterior and posterior. Usually not severe, an anterior nosebleed—from the front of the nose—is more prevalent. Deeper in the nasal passage, posterior nosebleeds might be more severe and usually call for medical intervention.
Common causes of epistaxis are nasal injuries, frequent nose-picking, dry air, allergies, respiratory infections, and blood-thinning drug use. Environmental elements, such as low humidity or abrupt temperature variations, can also be important. Occasionally the underlying cause can be anatomical defects, blood problems, or high blood pressure.
One should sit straight, lean forward, and softly pinch the nostrils together for ten to fifteen minutes to control a nosebleed. Steer clear of reclining down since the motion can let blood flow into the throat. While most nosebleeds are benign and self-limiting, a healthcare professional should see persistent or significant bleeding to rule out more serious diseases.
