Chronic Airway disease or Chronic Obstructive Pulmonary Disease (COPD) is an inflammatory disease affecting the lungs and its associated structures, resulting in obstructed airflow from the lungs. The disease is seen in people who work in areas with toxic fumes, smokers, and people suffering from severe infections or allergens or in people with genetic prevalence. The disease leads to shortness of breath, chest tightness, and wheezing, repeated cough with phlegm, lack of energy, and weight loss. The treatments for this disease include medication, inhalation, regular nebulization, diet, and lifestyle changes while varying the allergens.
