The main reason for sputum pulling may be that the sputum becomes sticky and is not easy to cough up in a pulling form, which is common in respiratory tract infections and chronic lung diseases, among others.
Sputum straining may be due to the fact that the sputum is thicker. When there are diseases such as chronic pharyngitis, chronic bronchitis, secondary infection of chronic obstructive pulmonary disease, tuberculosis, and lung tumors, the sputum that is coughed up may show the symptoms of sputum straining. When these diseases occur, some patients’ sputum is not easy to cough up, and it accumulates in the airways, where the sputum gradually becomes more concentrated and becomes stretched when coughed up.
When the symptoms of sputum pulling are combined with other discomforts such as cough, fever, chest pain, shortness of breath, etc., please consult a doctor in time to improve sputum culture, chest CT and other examinations to clarify the cause of the disease, and at the same time to exclude secondary fungal infections caused by malignant tumors resulting in coughing weakness.
