Patients sometimes experience nosebleeds after drinking alcohol because alcohol accelerates blood circulation, causing the patient’s blood pressure to rise. When the blood pressure rises, there is a possibility that the patient’s nasal vessels will rupture, and the bleeding is all relatively large. For treatment, the patient first needs to fill the nasal cavity on the bleeding side with cotton balls and pinch the nostrils bilaterally with hands to play the role of pressure to stop the bleeding. If the blood still does not stop, it is best to go to the hospital for detailed examination, and if necessary, electrocoagulation can be considered. Patients should pay attention to drinking alcohol in moderation, monitor blood pressure regularly, clarify the specific situation of the patient’s blood pressure, and consider oral antihypertensive drugs to control symptoms if necessary. Patients should also pay attention to the nasal mucosa moisturizing, can spray with physiological sea saline to relieve nasal mucosa dryness, also conducive to reduce the patient’s nasal bleeding.
