Heartburn or pyrosis is a painful or burning sensation in the esophagus, just below the breastbone caused by regurgitation of gastric acid. The pain often rises in the chest and may radiate to the neck, throat, or angle of the jaw. Heartburn is also identified as one of the causes of asthma and chronic cough.
Physicians normally diagnose gastroesophageal reflux disease (GERD) based on symptoms alone. When the clinical presentation is uncertain, other tests can be performed to confirm the diagnosis or exclude other disorders. Confirmatory tests include:
Upper Gastrointestinal (GI) Series: A series of x-rays of the upper digestive system are taken after drinking a barium solution. These can demonstrate the reflux of barium into the esophagus, which suggests the possibility of gastroesophageal reflux disease. More accurately, fluoroscopy can be used to document reflux in real-time.
Ambulatory pH Monitoring: A probe can be placed via the nose into the esophagus to record the level of acidity in the lower esophagus. Because some degree of variation in acidity is normal, and small reflux events are relatively common, such monitors must be left in place for at least a 24-hour period to confirm the diagnosis of GERD. The test is particularly useful when the patient’s symptoms can be correlated to episodes of increased esophageal acidity.
H2-receptor antagonists: With the advent of proton-pump inhibitors, H2-receptor antagonists are not widely used.
Proton-pump Inhibitors: Proton pump inhibitors are a class of medications that can be effective for people who do not respond to antacid or acid blockers. Proton-pump inhibitors directly block acid production in the stomach cells and provide more effective relief than less powerful medications. In order to prevent heartburn, the medication disfigures and disables the proteins (proton pumps) that control the pH of the stomach, allowing the body to digest them.
Restricting Diet: Restricting diet is very important since 90-95% of sufferers of heartburn or esophageal disorder can link their symptoms to specific foods. Therefore, it is important that heartburn sufferers manage their diets as a way to treat their heartburn. Sufferers should choose the kinds of foods and drinks which have little risk of causing acid reflux, while some kinds of foods or drinks should be avoided as they are major heartburn triggers.
