Recent research has shown a connection between obesity and the prevalence of digestive conditions such as heartburn, also known as gastroesophageal reflux disease (GERD). Several factors contribute to either developing or worsening GERD when the stomach increases in size. Reducing excess weight can typically resolve reflux. Michael A. Russo, MD, general surgeon specializing in bariatric surgery at the MemorialCare Center for Obesity at Orange Coast, discusses this connection between obesity and digestive conditions, and how to find resolution of GERD symptoms with weight-loss surgery.
