Acid reflux, also known as GERD (gastroesophageal reflux disease) is a painful condition where the acid from your stomach backflows into your esophagus and throat. It can feel like burning, or sometimes the only symptom is coughing, throat clearing, or hoarseness.
While some people can tolerate the pain, the problem is that reflux can lead to fairly serious damage in your esophagus. Too much damage to the lining of your esophagus can cause scarring and narrowing, and in some cases a pre-cancerous condition known as Barrett's esophagitis. If you have reflux symptoms, don't ignore them – you need to treat them now!
