Gastroesophageal reflux disease (GERD), or acid reflux, has a number of different causes. Heartburn is the pain characteristically associated with acid reflux and results from irritation of the lining of the esophagus. Some cases of heartburn can produce sharp chest pains in the mid-chest that can be mistaken for the pain of angina. Heartburn is typically worse when an individual lies down after eating and occurs most commonly after mealtimes.
Other symptoms that can occur as a result of GERD include
- regurgitation (the presence of regurgitated stomach contents in the mouth), and
- acid-induced erosions of the teeth.
In some cases, acid reflux can cause atypical symptoms, including
Causes of acid reflux (GERD)
The symptoms of acid reflux are caused by the regurgitation of acidic sour liquid stomach contents back up into the esophagus. Factors that may contribute to GERD include slow emptying of the stomach, lower esophageal sphincter abnormalities, hiatal hernia, and abnormal esophageal contractions.
