Question

Quizplus · Accepted Answer

High altitude is not typically a common cause of posterior nosebleeds. Posterior nosebleeds are usually more severe and can be caused by factors such as nasal tumors, serious nose trauma, or drug abuse, but not typically by high altitude. High altitude can cause nosebleeds due to dry air, but these are usually anterior nosebleeds, which are less severe and originate from the front part of the nose.
