Hello, this condition may be associated with bronchitis, pneumonia, bronchiectasis, pulmonary space-occupying lesions, pulmonary tuberculosis, hematologic disorders, or pharyngeal diseases. We recommend visiting the Department of Respiratory Medicine at a reputable hospital. Blood routine tests and chest radiography are required to establish a definitive diagnosis and guide appropriate treatment. If no pulmonary or systemic abnormalities are found, consider whether oral conditions—such as gingival bleeding near the posterior pharyngeal wall—might be contributing factors.
