Chronic obstructive pulmonary disease (COPD) is a lung condition  characterized by obstruction in airflow from the lungs. It is typically caused by chronic bronchitis, emphysema, or exposure to irritants or particulate matter. The symptoms of this condition include wheezing, difficulty breathing, cough, and mucus production. It is a progressive condition and, as the name suggests, chronic. However, you can manage it through lifestyle and dietary changes, and a good quality of life is within reach.  COPD and the immunity COPD is a complex condition affecting multiple organ systems. Though the illness can cause various complications like heart problems, high blood pressure, and lung cancer, the relationship between COPD and immunity is perhaps the most complex. Chronic inflammation is a complication of this condition and is a strong indicator of the immune system’s involvement in COPD. Chronic inflammation compromises immune functioning, allowing pathogens to make your lungs their new home. Since exposure to irritants is implicated, there is a natural response from both structural and immune cells in the lungs. Individuals with COPD are much more likely at risk of respiratory infections like colds, pneumonia, and flu, making breathing more difficult and damaging the lungs further. Managing COPD Though a diagnosis of COPD is not immediately life-threatening nor as scary as a cancer diagnosis, it will not be easy.
