November marks Chronic Obstructive Pulmonary Disease (COPD) Awareness Month, which is a chronic lung disease that makes it very difficult for people to breathe.
As a result of COPD, the air becomes progressively trapped inside the lungs due to excess mucus, scarring and narrowing of the air passages and destruction of the air sacs (emphysema). This means that air cannot get out of the lungs easily.
For people with the condition, breathing problems tend to get gradually worse over time and can limit their normal activities, although treatment can help keep the condition under control, according to the NHS.
