    Frequently Asked Questions About Acid Reflux

    Daily antacid use may mask underlying issues like GERD or esophageal damage. Chronic acid exposure can lead to Barrett's esophagus or strictures. A gastroenterologist can identify the root cause and provide targeted treatment beyond temporary symptom relief, preventing long-term complications.

    Acid reflux is occasional stomach acid backflow into the esophagus. GERD (gastroesophageal reflux disease) is chronic reflux occurring twice weekly or more, causing persistent symptoms and potential esophageal damage. GERD requires medical evaluation and comprehensive treatment to prevent complications like erosive esophagitis.

    Yes, acid reflux can cause laryngopharyngeal reflux (LPR), where stomach acid reaches the throat and voice box. This triggers chronic cough, hoarseness, throat clearing, and a sensation of a lump in the throat. These atypical symptoms often require specialized diagnostic testing.

    Treatment options include lifestyle modifications, dietary changes, weight loss, and minimally invasive procedures like LINX or fundoplication surgery. A gastroenterologist can evaluate your specific condition and recommend personalized solutions, including procedures that address the underlying mechanical causes of reflux.

    Common diagnostic tests include upper endoscopy to visualize esophageal damage, pH monitoring to measure acid exposure, esophageal manometry to assess muscle function, and barium swallow studies. Your gastroenterologist will recommend appropriate tests based on your symptoms and medical history.
