Heartburn is sometimes called acid indigestion and usually occurs after meals. People with severe esophageal reflux or with heartburn symptoms unresponsive to the measures described above may need more complete diagnostic evaluation. Endoscopy - a procedure where a flexible tube is placed into the esophagus whereby your physician will see the tissue lining of the esophagus. Biopsy - the removal of a small sample of tissue of the lining of the esophagus to better determine the causes of underlying disease. Esophageal manometric studies - pressure measurements of the esophagus, which identify critically low pressure in the lower esophageal sphincter muscle and determine other disorders of the esophageal muscle function.
Many physicians find it helpful to measure the acid levels inside the esophagus.
This is done by placing a thin tube in the esophagus. Although heartburn is common in our society, it is rarely life-threatening. However, heartburn can severely limit daily activities and productivity. With proper understanding of the causes of heartburn and a consistent approach to a treatment program, most people will find relief. Heartburn is not caused by hiatal hernia, which is the pushing up of the stomach into the chest cavity through a hole in the diaphragm.
