Asthma is a disease that inflames and narrows the airways in the lungs. As inflammation causes the airways to become narrower, less air can pass through them, both to and from the lungs. In addition, the airways become extremely sensitive to irritations which can cause an allergic reaction. This disease is thought to be caused by a combination of genetic and environmental factors.
Feinstein Institute researchers are studying the effects of air pollution on asthma-related hospital admissions. They are also investigating the relationship between diabetes and asthma as people with diabetes become resistant to steroids, a common treatment for asthma.
