Hello dear. Welcome to Healthcaremagic. I read your query and I understand your concern. The most common causes of nosebleeds are drying of the nasal membranes and nose picking (digital trauma), which can be prevented with proper lubrication of the nasal passages and not picking the nose. Chronic nosebleeds or persistent nosebleeds may need to be stopped with a heating instrument or chemical swab (cautery of the blood vessel that is causing the trouble), or application of a topical medicine called thrombin that promotes local clotting of blood. A doctor may use nasal packs to stop nosebleeds when conservative measures fail. Do not take aspirin or other blood thinning products when you get a nosebleed (if they are doctor-prescribed, consult your doctor before stopping any of them. . The following risk factors predispose people to nosebleeds: Infection Trauma, including self-induced by nose picking (this is a common cause of nosebleeds in children) Allergic and non-allergic rhinitis Hypertension (high blood pressure) Use of blood thinning medications Alcohol abuse Less common causes of nosebleeds include tumors and inherited bleeding problems Hormonal changes during pregnancy may increase the risk of nosebleeds. Take care. Hope my answer was helpful, if you have any other questions I ll be glad to help you. Best regards, Dr.Olgeta Xhufka ( general and family physician ).
