Reflux

Reflux occurs when stomach acid and sometimes food flow back up into the esophagus, the tube connecting your mouth to your stomach. This happens if the lower esophageal sphincter, a ring of muscle that normally keeps the stomach contents in place, weakens or relaxes inappropriately. The backflow can cause symptoms like heartburn, a burning sensation in the chest, and sometimes a sour taste in the mouth. Reflux can happen occasionally or become a chronic condition known as gastroesophageal reflux disease (GERD). Managing reflux may involve lifestyle changes, medications, or in some cases, surgery, to reduce acid and strengthen the barrier.
