Excess phlegm
Are you coughing up phlegm, but you’re not really sick? Well, it’s time to call your doctor as sputum (excess phlegm) is a pretty common symptom of chronic obstructive pulmonary disease. And yes, healthy people produce mucus, too, to keep the airways moist, but the mucus produced is way too much when it comes to COPD patients.
According to doctors, the excess phlegm caused by COPD can act as a spider’s web, attracting bacteria and other enemies that don’t belong in our bodies. If the sputum expelled is brown, green, yellow, or red, it means that you have a lung infection, so don’t ignore it!
