If spitted phlegm is hard in texture, it usually means that the phlegm stays in the respiratory tract for a long time, and breathing will keep drying the phlegm, and when the water of the phlegm is excessively reduced, it will form hard phlegm crusts, and hard lump-like phlegm will appear. In addition, when there is an inflammatory lesion in the respiratory system, it may lead to dryness of the respiratory tract, sticky phlegm that is not easily expelled, and hard lumps in the spitted phlegm may also be caused by pharyngitis due to bacterial infection. Such patients are recommended to undergo appropriate nebulization treatment to dilute phlegm or take oral medication to facilitate phlegm discharge, and to consciously cough up phlegm on their own in daily life to avoid prolonged blockage of the respiratory tract with phlegm. If you have hard lumps in sputum, you can drink more water to lubricate the sputum to help cough up the sputum. If the symptoms are serious and affect your life, you should go to the hospital in time to seek medical treatment, and the sputum culture or relevant examination can clarify the pathogenic bacteria for treatment.
