Asthma is a form of COPD or Chronic Obstructive Pulmonary Disease. It is a respiratory condition that involves the inflammation of the air passages. The muscles that surround these air passages then become very tight, so the lining swells. This inflammation, swelling, and tightness cause less air to enter the lungs. Asthma is commonly triggered by irritants in the environment. Some irritants are dust, climate change, animal hair, fur, or dander, pollen, mold, chemicals, tobacco smoke, exercise, infections of the respiratory tract, and stress. Certain medications like NSAIDs (non-steroidal anti-inflammatory drugs). A family history of allergies may also be one of the causes of asthma.
