Gastroesophageal reflux is a major contributor to exercise-triggered asthma.

Two groups of patients will be studied: those with asthma who have difficulty with exertion, those without asthma who experience difficulty with exertion. Both groups will experience gastroesophageal reflux (GER) twice of less per week. Patients will complete a treadmill exam to determine their VO2 max. They will then undergo pH monitoring while exercising for 30 minutes at 65-70% of their VO2 max. Subjects will be given placebo or acid suppression pill for 12 weeks. At the end of 12 weeks, the subjects will repeat the exercise (30 minutes) and 24-hour pH study.

Further study details as provided by University of Utah:

Primary Outcome Measures:
  • To determine whether patients with exercise-triggered asthma experience GER during exercise.

Secondary Outcome Measures:
  • To determine whether the exercise-induced GER within the subjects relates temporally to their exertional asthma.
