2 days agoI have frequent nosebleeds. What causes it and is it normal?
A nosebleed, known medically as epistaxis, comes in two forms: anterior and posterior. About 90% of nosebleeds are anterior, and start in the area between your two nostrils, called Kiesselbach's plexus, says Loftus. This area contains a lot of blood vessels little capillaries that keep the nostrils well supplied with blood, to warm the air you inhale. These can break open, creating a bleed that mostly pours from the nostril, though some blood may trickle into the mouth or throat, especially if you lean your head back.
