Patient's question:
NoDoctor's answer:
Hello, nosebleed refers to the condition where fragile capillaries in the nostrils are damaged, causing blood to flow from the nostrils. There are many causes of nosebleeds, including nose trauma, dry crusts forming on the mucosa, damage from acidic or alkaline foreign substances, and excessive sun exposure. You can take vitamin K4, use to plug the nose, then apply pressure to stop the bleeding, and gently remove the cotton. Of course, if the bleeding is heavy, it's important to seek medical attention promptly.
