Acid reflux is a diagnosis linked to adult onset asthma. There are many over-the-counter meds on the market now that help w/reflux. The following is some info taken from Professional Guide to Diseases:
Pt with reflux should eat a low-fat, high-fiber diet & avoid caffiene, tobacco, and carbonated beverages. Pt should not eat 2 hrs before going to bed & avoid tight clothing; elevate the head of the bed 6 - 8 inches and maintain a normal body weight.
Hope this helps.
