Asthma is a condition of the lungs characterized by inflammation and reversible narrowing of the airways, affecting children and adults. Asthma is very common, and often related to allergy. Pulmonary function tests may be needed to determine if narrowing of the airway is present. Goals for the treatment of asthma are to control or minimize symptoms and normalize lung function. Most of our providers also can diagnose and treat COPD (Emphysema and Chronic Bronchitis).
