Gastroesophageal reflux disease (said: GAST-ro-eh-sof-uh-GEE-ul REE-flux duh-ZEEZ), or GERD, is often called acid reflux disease or heartburn. In GERD, acid from the stomach goes (refluxes) into the esophagus. The esophagus is the tube that connects the mouth to the stomach. When reflux happens too often, it causes irritation that can lead to painful symptoms and damage to the esophagus.
Do you take over-the-counter or prescription medicine for GERD? If you do, tell your healthcare provider. Some medicines for GERD can keep your HIV medicines from working.
