Gastroesophageal reflux disease (GERD) is a chronic digestive disease that occurs when stomach acid or stomach content flows back into the esophagus, causing damage to it. This is commonly called acid reflux or heartburn.

People who are overweight are 50% more likely to suffer from GERD and/or heartburn. Excess weight puts more pressure on your stomach, which then puts pressure on the valve opening to your esophagus. Slimming down to a healthier weight can reduce and often eliminate your food-related heartburn and GERD.
