''Gastroesophageal reflux disease (GERD) and asthma are common as independent conditions, and GERD is present in 34 to 90 percent of patients with asthma. Little is known about the way these two conditions co-exist or the way GERD exacerbates asthma.''
''If you have asthma, your chances of having GERD are higher than those without the condition. Studies show that as many as 70% of patients with asthma have GERD compared to 20%-30% of the general population.''
