For southern Maryland residents in need of digestive care, the GI Associates of Maryland and Waldorf Endoscopy Center are the unquestioned market leader. What We Do Gastroenterology is a subspecialty of medicine that involves the diagnosis and treatment of disorders of the gastrointestinal tract (esophagus, stomach, small and large intestines, and rectum) as well as the gallbladder, liver, and pancreas. Gastroenterologists treat such diseases or disorders as gastroesophageal reflux, peptic ulcers, chronic diarrhea, abdominal pain, colitis, colon polyps and cancer, irritable bowel syndrome, hepatitis, and liver cirrhosis. Gastroenterologists have at least two additional years of training in digestive disorders after finishing their training in internal medicine. Your GI Associates physicians are all Board Certified in both Internal Medicine and Gastroenterology. They are also active in the American Gastroenterological Association and the American College of Gastroenterology. Our physicians will work closely with your personal physician and/or surgeon to detect GI diseases early and treat these effectively with medication or surgery. Our goal will be to minimize your discomfort, expense, and time in arriving at a sound medical diagnosis and treatment plan.
