Winter is a high season for rhinorrhea, mainly due to dry weather which leads to dry mucous membrane in the anterior part of nasal cavity. Since the anterior part of nasal cavity has rich vascular network, excessive dryness of mucous membrane can lead to exposure of blood vessels, which can easily lead to rhinorrhea when local rupture or repeated nose digging occurs. First of all, nasal endoscopy should be improved to find the site of bleeding. If there is a definite bleeding point, electrocoagulation and nasal tamponade can be done to stop the bleeding; if there is no definite bleeding site, saline can be used to rinse the nasal cavity and peppermint paraffin oil can be applied to the nose to keep the local mucosa moist and promote the recovery of mucosal function. For elderly patients, especially those with hypertension, due to the high brittleness of blood vessels, it is necessary to actively control hypertension. At the same time, you can eat more fresh vegetables and fruits, which contain many vitamins that can change the permeability and brittleness of blood vessels, and can also participate in blood clotting function which is very effective in relieving nosebleeds.
