Gastroesophageal Reflux Disease (GERD)
What Is the Treatment for GERD? continued...
Long-term use of antacids, however, can result in side effects, including diarrhea, altered calcium metabolism (a change in the way the body breaks down and uses calcium), and buildup of magnesium in the body. Too much magnesium can be serious for patients with kidney disease. If antacids are needed for more than 2 weeks, a doctor should be consulted.
For chronic reflux and heartburn, the doctor may recommend medications to reduce acid in the stomach. These medicines include H2 blockers, which inhibit acid secretion in the stomach. H2 blockers include: cimetidine (Tagamet), famotidine (Pepcid), nizatidine (Axid), and ranitidine (Zantac).
Another type of drug, the proton pump inhibitor (or acid pump), inhibits an enzyme (a protein in the acid-producing cells of the stomach) necessary for acid secretion. Some proton pump inhibitors include esomeprazole (Nexium), lansoprazole (Prevacid), omeprazole (Prilosec), pantoprazole (Protonix), rabeprazole (Aciphex), dexlansoprazole (Dexilant) and omeprazole/ sodium bicarbonate (Zegerid).
Other approaches to therapy will increase the strength of the LES and quicken emptying of stomach contents with motility drugs that act on the upper gastrointestinal (GI) tract. These drugs include bethanechol (Urecholine) and metoclopramide (Reglan).
What If Heartburn or GERD Symptoms Persist?
People with severe, chronic esophageal reflux or with symptoms not relieved by the treatments described above may need more complete diagnostic evaluation. Doctors use a variety of tests and procedures to examine a patient with chronic heartburn.
An upper GI series may be performed during the early phase of testing. This test is a special X-ray that shows the esophagus, stomach, and duodenum (the upper part of the small intestine). While an upper GI series provides limited information about possible reflux, it is used to help rule out other diagnoses, such as peptic ulcers.
Endoscopy is an important procedure for individuals with chronic GERD. By placing a small lighted tube with a tiny video camera on the end (endoscope) into the esophagus, the doctor may see inflammation or irritation of the tissue lining the esophagus (esophagitis). If the findings of the endoscopy are abnormal or questionable, biopsy (removing a small sample of tissue) from the lining of the esophagus may be helpful.
Esophageal manometric and impedance studies -- pressure measurements of the esophagus -- occasionally help identify low pressure in the LES or abnormalities in esophageal muscle contraction.
For patients in whom diagnosis is difficult, doctors may measure the acid levels inside the esophagus through pH testing. Testing pH monitors the acidity level of the esophagus and symptoms during meals, activity, and sleep. Newer techniques of long-term pH monitoring are improving diagnostic capability in this area.
Does GERD Require Surgery?
A small number of people with GERD may need surgery because of severe reflux and poor response to medical treatment. Fundoplication is a surgical procedure that increases pressure in the lower esophagus. However, surgery should not be considered until all other measures have been tried. Endoscopic procedures that involve making the LES function better or using electrodes to promote scarring of the LES are newer options in treatment.
