It is the condition where prolonged refluxes of the acids in your stomach (namely hydrochloric acid and pepsin) occur leading to intestinal and respiratory problems. This is a recurring disease whose root cause lies in your gut and the lower stomach. The reflux of these acids can harm the mucosa or the lining of your foodpipe, mouth and sometimes even the windpipe. Changes in the lifestyle, eating habits, medications, dysfunctional habits and hormonal stability are the factors that can cause or cure this disease based on how the action is taken. The disease ranges from mild to severe based on its intensity.
