Gastroesophageal reflux disease (GERD) is a common condition where stomach acid flows back into the esophagus, the tube connecting the throat to the stomach. This backflow can cause symptoms like heartburn, regurgitation, and difficulty swallowing. Over time, GERD can lead to more serious health issues if not treated properly. Many factors can contribute to GERD, including obesity, pregnancy, and certain foods like chocolate and spicy dishes. Lifestyle changes, medications, and sometimes surgery can help manage the symptoms. It's important for those experiencing frequent symptoms to consult a healthcare professional for proper diagnosis and treatment options.
