Asthma

The Asthma topic includes research on the causes, progression, treatments, and outcomes of the chronic lung disease asthma, along with research on allergies directly associated with asthma.

Asthma is a long-term condition that causes inflammation and narrowing of the airways in the lungs, making it harder to breathe. Severe asthma attacks can be life-threatening and may require emergency room visits and hospitalizations. Asthma often begins in childhood. Pollen, exercise, cold air, and viruses can all trigger or worsen asthma, which has been linked to both genetic and environmental factors.
