Throat bleeding caused by minor trauma or dietary stimuli can often heal spontaneously after the mucous membrane heals after the stimuli are eliminated. Throat bleeding caused by chronic pharyngitis, pharyngeal tumor disease is difficult to heal. 1. Minor trauma or dietary stimulation: in the presence of small trauma and injury to the mucous membrane of the throat, capillary rupture bleeding in the coagulation mechanism can play a role in natural hemostasis and enter the natural repair process of trauma, which is the mechanism of self-healing. 2. Chronic pharyngitis and pharyngeal tumor: bleeding from ulcers and erosions of the pharyngeal mucosa due to chronic inflammation and bleeding from foci due to tumor invasion or disease progression are generally not able to return to normal on their own. If it is a malignant tumor or vascular origin disease, the dose and frequency of bleeding is even more intense. After the discovery of throat bleeding, should promptly go to the hospital otorhinolaryngology, identify the cause under the guidance of the doctor standardized diagnosis and treatment.
