Blood in the sputum of the throat may be caused by excessive coughing, laryngitis, bronchitis and other reasons.
1. Excessive coughing: If you cough hard for a long time, it will lead to the rupture of small blood vessels in the mucous membrane of the pharynx, and the situation of blood in the sputum of the throat.
2. Pharyngitis: If the patient’s immunity is low, it leads to throat pathogen infection. Inflammatory reactions in the throat cause capillary edema and oozing blood, and phlegm is discharged through the throat with oozing blood, so there is blood in the sputum in the throat.
3. Bronchitis: Infection of the bronchial tubes due to viral and bacterial infections. Inflammation of the bronchial mucosa causes localized congestion and edema, and coughing hard may cause blood to seep out of the throat, causing the patient to spit out blood in the throat.
When the patient spits out sputum with blood in the throat may also be caused by bronchial dilatation, tuberculosis and tumors, etc., it is recommended to go to the hospital in time to identify the cause of the disease, and carry out the relevant treatment after the cause of the disease is clear.
