Gastroesophageal reflux disease GERD, or gastric reflux disease, is a chronic condition where stomach acid flows back up and damages the mucosa of the food pipe the esophagus. At the junction between the esophagus and the stomach is the lower esophageal sphincter the LES. The LES is a ring of muscle that is generally closed tight to prevent stomach acid from coming up. In normal digestion, the LES only opens briefly with each swallow to allow food bolus to pass down into the stomach. GERD occurs when the LES is ABNORMALLY.
Relaxed and cannot close properly. Heartburn is a burning sensation in the chest associated with each regurgitation of gastric acid and is the most prominent symptom of GERD. Hiatus hernia is believed to be another cause of GERD. Hiatus hernia is a condition where the top portion of the stomach is pulled up forming a herniation above the diaphragm. This situation somehow compromises the barrier between the esophagus and the stomach, facilitating acid reflux. If left untreated, GERD can lead to a number of complications, including Esophageal stricture narrowing of the.
Esophagus as scar tissue builds up from reflux damage. The resulting narrowed food pathway may cause difficulty swallowing. Esophageal ulcer open sore as a result of acid erosion. An ulcer may bleed, cause pain and again make swallowing difficult. Barrett’s esophagus precancerous changes to the esophagus. These changes are associated with an increased risk of esophageal cancer. GERD can be treated with dieting, life style changes and medication. Patients are advised to maintain a healthy weight avoid alcohol, tobacco and foods or drinks that trigger heartburn wait at least 34h after eating before going.
