What is a common symptom of GERD?

Heartburn is a hallmark symptom of gastroesophageal reflux disease (GERD). This condition occurs when stomach acid frequently flows back into the esophagus, leading to a burning sensation that can be felt in the chest area. This sensation is often triggered or exacerbated by certain foods, beverages, or activities that increase abdominal pressure or relax the lower esophageal sphincter, allowing acid to escape from the stomach.

While dizziness, loss of appetite, and severe abdominal pain can occur with various medical conditions, they are not specifically characteristic of GERD. Dizziness may arise from other issues, loss of appetite could be associated with a variety of dietary or psychological factors, and severe abdominal pain usually suggests a more acute condition, such as appendicitis or pancreatitis. Understanding the primary symptom of heartburn aids in identifying GERD and distinguishing it from other digestive disorders.
