If you cough up sputum with blood in the morning, consider that there is inflammation of the upper respiratory tract, because colds are now mostly viral infections. Viral infections not only cause fever and upper respiratory symptoms, but may also be combined with bacterial infections. So the morning sputum with blood is considered to be the inflammation of the respiratory tract caused by respiratory mucosal congestion, when coughing, the respiratory tract due to congestion and edema of the mucosa is prone to rupture, some of the very fine blood vessels rupture will appear after coughing up sputum with blood. If this problem occurs frequently, it is not excluded that it is related to inflammation of the nose. Rhinitis can sometimes be there, and acute rhinitis is also easy if it is caused by a cold. Acute if accompanied by nasal congestion and nasal inaccessibility, there may also be coughing up sputum with blood, because after a person lies down, nasopharyngeal snot sometimes backflow to the pharynx, and sometimes there is congestion and edema of the nasal mucosa. Especially patients with chronic rhinitis, this time if there is mucus or blood will flow into the pharynx. When coughing in the morning, it will be coughed out, or snot stimulation of the pharynx caused by pharyngeal inflammation aggravation, there will also be coughing sputum with blood. Coughing up sputum with blood caused by acute colds, the first consideration is the inflammation of the airway caused by mucosal congestion and edema, rupture, or acute rhinitis, nasal mucosal damage caused by the situation. For repeated cases, it is still recommended to do rhinolaryngoscopy according to the patient’s symptoms, or to exclude lung diseases. Especially in middle-aged and elderly patients, it is recommended to check in detail is better.
