COPD – Diagnosis and stages
To treat any disease, doctors evaluate a number of factors like the cause, frequency, severity, duration, specific triggers, other illnesses, and the patient’s state of physical health, age, and gender. For progressive diseases, doctors evaluate the stages of the disease as well. Chronic Obstructive Pulmonary Disease, or COPD, is one such health condition that continues to develop and intensify over time. People who can be at risk of developing COPD include smokers, passive smokers, those living in areas with heavy air pollution, and, although rare, those with a genetic disorder. Affecting the lungs, in particular, this is a group of diseases including emphysema and chronic bronchitis, that can disturb the normal breathing pattern in a patient by curbing the smooth movement of air inside and out of the lungs. Therefore, shortness of the breath and constant cough with or without phlegm are the most prevailing symptoms in people with COPD. By categorizing COPD into different stages, doctors can understand how the illness affects various people, weigh in the treatment options that can be adopted, and pay attention to the research required to prevent the onset of COPD. Spirometry is the most commonly used pulmonary function test that evaluates the efficient functioning of the lungs.
