We might not heed a cough that won’t go away or wheezing while breathing, assuming it might be because of air quality or changing weather. However, mild but chronic symptoms like these must be noted down. People often think that trouble with breathing is normal as they get older, but these might be signs of severe lung disease. With this in mind, here are six warning signs of poor lung health that should not be ignored. Chronic cough A cough that won’t go away and has been around for eight weeks or longer is considered chronic. The constant symptom indicates something might be wrong with the individual’s respiratory system. If one experiences this, they should visit a healthcare expert for an opinion immediately. Excessive mucus production The mucus lines the surfaces of organs like the lungs and serves as a lubricant to keep tissues from drying out and as a line of defense. But if someone develops excessive mucus in their throat or chest that won’t go away, it could be a sign of lung disease. Wheezing Noisy or strained breathing is a potential sign that something might be obstructing the airwaves in the lungs or forcing them to narrow.
