Gastrointestinal
Conditions we treat
We offer diagnostic and treatment options for common and complex gastrointestinal disorders from heartburn and eosinophilic esophagitis to irritable bowel disease and inflammatory colitis etc. We are committed to combining best practices in clinical medicine with the latest research findings for high-touch patient treatment. Dr. Leung is continually involved in research efforts to provide cutting-edge therapies and clinical trials to our patients. Proximity to Tufts Medical Center makes it even easier for patients to efficiently get the endoscopy procedures they need to progress in their treatment plan.
We assist new patients to obtain outside medical records, and Dr. Leung carefully reviews these documents prior to you or your child's visit. Upon reviewing your clinical history, physical exam, and previous laboratory, histological, and endoscopic data, we confirm a diagnosis and provide you with a customized treatment plan. We treat a broad range of conditions, not exclusive to those listed.
