GERD (gastroesophageal reflux disease) is characterized by the backward flow of stomach contents into the esophagus due to a malfunctioning LES (lower esophageal sphincter). PUD (peptic ulcer disease) is a condition characterized by open sores in the lining of the stomach or small intestine. IBS (irritable bowel syndrome) and IBD (inflammatory bowel disease) are chronic digestive conditions affecting the large intestine, with different symptoms and causes than GERD.
