The anterior and inferior portions of the nasal septum are richly vascularized, crossed into a mesh, and the vessels are superficial. When an inflammatory infection, mucosal rupture, or trauma occurs, it leads to localized bleeding. If the symptoms of nosebleed occur repeatedly when washing the face, there may be a clear bleeding point. It is recommended to complete the nasal endoscopy, observe the whole nasal cavity from front to back, pay special attention to the anterior and inferior regions of the nasal septum, if there is obvious active bleeding, it is recommended to do nasal tamponade or electrocoagulation to stop bleeding. If no clear bleeding site is found, you can use saline to rinse the nasal cavity to keep the mucous membrane moist and promote the recovery of mucous membrane function. Meanwhile, you can consume more fresh vegetables and fruits, because they are rich in many kinds of vitamins, which can improve the permeability and toughness of blood vessels, and can also participate in the coagulation mechanism.
