Maintain a moderate weight

Above your stomach is a muscle known as the diaphragm. The lower esophageal sphincter is typically strengthened by the diaphragm, preventing excessive amounts of stomach acid from flowing into the esophagus.

The lower esophageal sphincter may be pushed upward and away from the support of the diaphragm, though, if you have excess belly fat. The most common cause of GERD is thought to be this condition, also known as a hiatal hernia. Additionally, studies suggest that having too much belly fat may increase your risk of GERD and acid reflux. For this reason, some studies indicate that people with GERD may have a considerable reduction in GERD symptoms by decreasing at least 10% of their body weight. In the longterm, achieving and maintaining a moderate body weight can help to lessen acid reflux.
