For more than 30 years, we've known about the connection between asthma and gastroesophageal reflux disease, also known as GERD. GERD is often called heartburn, but heartburn is actually just one of the symptoms. We've also known that GERD can trigger asthma symptoms, and that anywhere from 50% to 80% of people with asthma have GERD.
But what hasn't been clear was which was the proverbial chicken and which was the egg. In other words, did GERD cause asthma... or did asthma cause GERD?
Good...
