What can i do about hyperinflated lungs due to untreated asthma?

Talk to your doctor: Asthma is an inflammatory airway condition that causes airflow obstruction resulting in hyperinflation. Asthma controller medications (typically inhalers or nebulizer therapies) can help alleviate the inflammation and bronchoconstriction causing obstruction and air-trapping. Discuss this with your md to help determine an appropriate treatment strategy.
