Gastroesophageal reflux disease, or GERD, causes stomach contents (food or liquid) to leak backwards into the esophagus (the tube from the mouth to the stomach). The backwash can irritate the esophagus, causing heartburn and other symptoms.
Anyone can get GERD. Those at a higher risk include males and people with a family history of GERD. Obesity can increase the risk of GERD up to six-fold.1-4 Hiatal hernia, smoking, pregnancy, and alcohol consumption are also risk factors.5,6
The prevalence of GERD is increasing worldwide. It is estimated that GERD affects1:
The common symptoms of GERD include chronic heartburn (burning pain in the chest) and regurgitation.3 Less common symptoms include chronic cough, sore throat, and a hoarse voice.3

GERD is often diagnosed based upon symptoms and response to anti-acid medication.7 Yet symptoms alone are not enough to diagnose GERD, and testing is required for conclusive diagnosis.7 Clinical studies reveal that as many as one in three patients taking proton pump inhibitors (PPIs) do not have GERD.8
If you have a diagnosis of GERD based upon symptoms, take PPIs regularly, and still have reflux symptoms, speak to a GI about a reflux test. The Bravo™ reflux testing system provides information, so your doctor can tailor therapy to your needs.
GERD can be treated with lifestyle changes, such as weight loss, healthier meals, eating smaller portions, and not eating just before bed time. Prescription and over-the-counter medicines, like proton pump inhibitors, can lower the amount of acid released in your stomach.
For patients who do not respond to lifestyle changes and medication, anti-reflux procedures may also be an option. Talk to your doctor about these options.
In addition to its negative impact on health-related quality of life, GERD may lead to serious diseases, including Barrett's esophagus.4 GERD patients are 6 to 8 times more likely to have Barrett's esophagus in their lifetime.7
If untreated, Barrett’s esophagus may progress to esophageal cancer.6 Esophageal cancer may not be curable depending on the stage at diagnosis. It has a low five-year survival rate of 19%.5,8
