Hello! Most likely your primary care doctor will monitor your reflux treatment plan. If you are on reflux medication, this may occur every 6 months (more or less, depending on the severity of your reflux). Periodically, your primary care doctor may refer you to a gastroenterologist for an endoscopy. This test will examine the lining of the esophagus and stomach for signs of irritation and esophagitis. . Have you had an endoscopy before? Did the doctor tell you when to come back for a follow up endoscopy? Sometimes the GI doctor will repeat the endoscopy in 1-2 years but again, it can be more or less depending on your symptoms and the severity of the irritation/esophagitis.   Take care, Jan
