Unilateral epistaxis is mostly caused by local causes, and bilateral epistaxis is mostly caused by systemic diseases. Hemorrhage in front of nose is more common in children and young people, and it is mostly caused by trauma, rhinitis and vitamin deficiency. Posterior nasal bleeding is more common in adults or elderly patients, and is mostly caused by diseases such as hypertension and arteriosclerosis. Children often have nosebleeds due to nose digging, foreign bodies being stuffed into the nasal cavity, and nasal trauma. Climate change, emotional excitement, fatigue, sneezing and even blowing your nose may all be the causes of nosebleeds.

When nosebleeds, the patient should be calm, sit still or lie flat, hold his nose with his fingers, hold down the hemostasis point, and breathe through his mouth temporarily; Put clean cotton, cloth or paper into nostrils to compress and stop bleeding. If you use gauze and cotton soaked in hydrogen peroxide, adrenaline or ephedrine solution, the effect will be better. You can also apply cold water to your forehead or back neck, fill sterile and fine vaseline gauze strips into the nasal cavity from the front nostril, press the bleeding point, and take it out after 24-48 hours; If the bleeding continues. It can be replaced and refilled. There are two simple prescriptions for nosebleeds:
