How have asthma inhalers changed as understanding of asthma has broadened? How could obesity, low Vitamin D, and other factors trigger asthma?

Historically, asthma medication has targeted the tightening of the airways (or bronchial tubes) that accompanies an asthma attack. But according to pulmonologist Dr Edward Eden, this has only addressed on part of the problem:

“The medications that have been developed now target particular areas of the immune system that we feel are responsible for causing inflammation in the lungs.”

Consequently, asthma sufferers are seeing a tighter and longer-lasting control of their symptoms on the newer asthma inhalers–if they’re able to afford them.
Importantly, Vital Signs host Brendon Fallon explores with Dr. Eden how insurance hurdles–to getting these drugs affordably–might be negotiated.

As a pulmonologist, Dr. Eden is focused on treating diseases of the respiratory system, including asthma. He is Professor of Medicine and Clinical Director of the James P. Mara Center for lung disease.

Despite the drop in tobacco smoking in recent decades we continue to see a rise in asthma in both adults and children. What role could obesity, low Vitamin D, and exercising–in the wrong time and place–play in triggering asthma?
