Gastroesophageal reflux disease, or GERD, is a digestive disease characterized by chronic acid reflux.
Gastroesophageal reflux disease, or GERD, is a digestive disease characterized by chronic acid reflux, which occurs when stomach acid flows back into the esophagus.
GERD is a common condition, affecting 44% of U.S. adults every month and nearly 20% of U.S. adults every week.1 People of all ages can be affected by GERD, including children.2,3
GERD is typically treatable, but many people may not know they have it because its symptoms are associated with numerous other conditions.
Common symptoms of GERD include:4,5
It’s normal to experience reflux symptoms every now and then, especially after a large meal. Acid reflux is considered GERD if symptoms occur at least twice per week or moderate to severe symptoms occur once a week. To know for sure if these are symptoms of GERD, consult a gastroenterologist (GI). A GI can perform diagnostic testing. Reflux testing is the most accurate way to determine if you have GERD.
When diagnosis and treatment are delayed, chronic GERD can increase your risk for serious health complications, including Barrett’s esophagus and esophageal cancer.6 About 16.3% of GERD patients may eventually develop Barrett’s esophagus.7

If you suffer from chronic heartburn, acid reflux, or similar symptoms, you may have GERD. Use this resource to track your symptoms. Discuss the results with a gastroenterologist — so together you can take the first step toward treatment.
There are several possible causes of acid reflux. However, it is commonly the result of a poorly functioning lower esophageal sphincter (LES), the valve between the esophagus and stomach.8 The lower esophageal sphincter (LES) valve is designed to open only when you swallow to allow food to pass into your stomach. The valve seals shut to block out stomach contents at all other times. Acid reflux occurs when the LES valve is weakened or doesn’t close properly, allowing stomach acid to rise into the esophagus.
Eating a large meal can cause the stomach to stretch out and temporarily weaken the LES valve. Other factors that can weaken the LES valve include:9
