Understanding the Relation Between Asthma and COPD
Asthma and Chronic Obstructive Pulmonary Disease (COPD) are respiratory ailments that are often confused for each other due to overlapping symptoms and little understanding of the two conditions. The National Institute of Health (NIH) says that about 40% of people with COPD also have asthma. The NIH also estimates that 24 million Americans suffer from COPD though about half of them are not aware of it. If you suspect that you are suffering from any of these two conditions, it is important to understand the similarities and differences between COPD and asthma for better management of these conditions. What is asthma? Asthma is an allergic reaction that often develops in early childhood. Health experts have never pinpointed why people develop asthma, but only that asthma attacks are triggered by allergens. These include dust, dust mites, mold, pollen, strong perfumes, certain foods, and food additives. The allergic attack causes inflammation that constricts the airways. Asthma attacks differ in severity depending on exposure to the triggering allergen. An asthma attack is relieved using a bronchial dilator to expand the airways and allow free movement of air. What is COPD? COPD is a disease that develops later in life due to the effects of exposure to particulate irritants especially tobacco smoke. This is usually observed in smokers above the age of 40 years. COPD is a progressive disease whose effects are treatable but irreversible. It is characterized by progressive airflow limitation and degrading of lung functions. This leads to respiratory complications including shortness of breath, coughing, and frequent throat clearing. COPD is a leading killer in smokers, being attributable to the death of about 150,000 Americans each year. Chronic bronchitis and emphysema are respiratory complications commonly observed in people with COPD. Chronic bronchitis happens when the bronchial tubes are inflamed leading to excessive coughing and mucus production.
