Gastroesophageal Reflux Disease is an unpleasant condition that occurs as a heartburn, swallowing difficulty, regurgitation and other physical complications. This condition occurs when our stomach acid continuously flows back into the tube connecting the mouth and stomach. GERD is a widely spread health condition that affects approximately one out of every five people in the western world. People with severe asthma symptoms are more likely to experience this disease. Asthma flare-ups can cause the esophageal sphincter to relax and let stomach contents flow back. Certain asthma medicines, both OTC and prescription, can worsen reflux symptoms. At the same time, acid reflux can worsen asthma symptoms by irritating the lungs and airways. This unnecessary irritation can trigger an allergic reaction and make your airways more sensitive to environmental conditions like cold air or smoke.
