Millions of Americans live with asthma, and there are several other respiratory illnesses that are categorized as breathing disorders. These include pneumonia, emphysema, and chronic bronchitis. Respiratory conditions are typically managed and treated with inhaled bronchodilators or corticosteroids. Having a respiratory illness can be stressful as normal activities, like exercising, can become difficult. The recent rise in lung conditions may be caused by an increase in air pollution, but genetic and other environmental causes factor in as well. Start treatment early to make your condition more manageable in the long run.
