Gastroesophageal reflux disease, referred to as GERD, is a chronic, often life-long, condition in which the stomach’s liquid contents back up into the esophagus causing inflammation or damage to the esophagus lining. Some GERD, or acid reflux, occurs in most people. However, in people diagnosed with GERD, the refluxed liquid has more acid content and remains in the esophagus for a longer period of time.
Indigestion, acid reflux and heartburn are experienced by most of us occasionally as brief periods of discomfort. When these symptoms become chronic – last longer, are stronger and occur frequently – they may signal more serious conditions such as GERD or hiatal hernia.
What is GERD?
GERD is a chronic condition in which the stomach’s liquid contents back up into the esophagus (the tube connecting the mouth to the stomach). These stomach acids and bile salts can irritate and damage the delicate lining of the esophagus and cause heartburn and other symptoms of distress.
What is a Hiatal Hernia?
A hiatal hernia is an upward bulge of part of the stomach through the muscular wall of the diaphragm into the chest. This happens when the natural opening (hiatus) in the diaphragm is either weakened or too large. There are two types of hiatal hernia:
Sliding: the bottom of the esophagus and the top of the stomach push up into the chest. This is the more common type.
Paraesophageal: part of the stomach bulges up into the chest so that it is positioned next to the esophagus. This type is less common and more likely to lead to complications.
Hiatal hernias occur more often in women, people who are overweight and those who are more than 50 years old.
