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 18% of U.S. adults every week.1 People of all ages can be affected by GERD, including children.2,3
GERD is typically a very treatable disease, but many people don't 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 26.5% of GERD patients will eventually develop Barrett’s esophagus.7
There are several possible causes of acid reflux. However, it is most 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
If you observe that your acid reflux only occurs after large meals or after eating certain foods, start by changing your eating habits. Eliminate trigger foods from your diet, eat smaller meals, and stay upright for two hours after eating. If your symptoms don’t improve, make an appointment with your doctor.
