    Dr. Christopher C. Thompson is the Director of Endoscopy at Brigham and Women’s Hospital (BWH), Co-director of the Center for Weight Management and Wellness, and Professor of Medicine at Harvard Medical School.  He is also the Advanced Endoscopy Fellowship Program Director and clinical faculty at Boston Children’s Hospital and the Dana-Farber Cancer Institute.  Dr. Thompson’s clinical interests include endoscopic surgery applied to foregut conditions, with a focus on endoscopic treatment of obesity, GERD, Zenker’s diverticula, achalasia, gastroparesis,  postsurgical complications, and pancreatobiliary disease.  He spends the majority of his time performing these advanced endoscopic procedures and also cares for these patients in the ambulatory setting.  The remainder of his time is devoted to research in endoscopic surgery, with a focus on device development, clinical outcomes, and endoscopic education. His research has resulted in numerous patents, development of new endoscopic procedures, and over 300 publications.  He was awarded the Brigham and Women’s Physician Organization Clinical Innovation Award in 2007 for developing and performing the first endoscopic suturing procedure to treat obesity.  He also invented anastomosis technology, which has been shown to treat type 2 diabetes effectively in early clinical trials.  He was responsible for much of the early work in Bariatric Endoscopy, having been called the founding father of the field, and edited the first textbook and video atlas on the subject.  Some of his other important clinical innovations include the development of new endoscopic techniques for treating pancreatic necrosis, gastric outlet obstruction, sleeve gastrectomy stenosis, pancreaticojejunal anastomotic strictures, and postsurgical complications.  He also developed an endoscopic part-task simulator used by many fellowship programs (the TEST box).These accomplishments have led to a broad clinical referral base, and to national and international invitations for lectureships and live case demonstrations, including the American College of Gastroenterology (ACG) Blackwell Lectureship, ACG American Journal of Gastroenterology Lecture, American Gastroenterological Association (AGA) Presidential Plenary Lecture, American Society for Gastrointestinal Endoscopy (ASGE) J Edward Berk Presidential Plenary Lecture, ACG Edgar Achkar Visiting Professorship, all post-graduate education courses for the major US gastroenterology and surgical societies, and numerous respected courses throughout Europe, Asia, and South America.  He has also mentored more than 20 fellows, many of whom have gone on to thrive in prestigious academic institutions, and he established the first Fellowship in Bariatric Endoscopy.

    What is the definition of Small Bowel Bacterial Overgrowth?

    Small bowel bacterial overgrowth is a condition in which very large numbers of bacteria grow in the small intestine.

    When should I see a Small Bowel Bacterial Overgrowth doctor in Massachusetts, US?

    There are various reasons why you may want to see a specialist, such as: 

    • Your primary care provider recommends it. 
    • Your condition requires expert knowledge and specialized care. 
    • Your symptoms persist or worsen despite treatment. 
    • You need specialized testing or procedures. 
    • You want a second opinion.  

    What should I consider when choosing a Small Bowel Bacterial Overgrowth doctor in Massachusetts, US?

    It’s important to see a provider with expertise in your specific condition. Each provider profile in MediFind’s doctor database includes information on which conditions they treat, years of experience, research contributions, languages spoken, insurance plans accepted, and more.  

    How does MediFind rank Small Bowel Bacterial Overgrowth doctors in Massachusetts, US?

    MediFind’s rankings are based on a variety of data sources, such as the number of articles a doctor has published in medical journals, participation in clinical trials and industry conferences, as well as the number of patients that provider sees for a given condition. Note that MediFind’s provider database is not based on user reviews, and providers do not pay to be included in the database. 

    What types of insurance are accepted by Small Bowel Bacterial Overgrowth doctors in Massachusetts, US?

    Most profiles in MediFind’s doctor database include a list of insurance plans accepted by that provider. However, it’s a good idea to contact the provider’s office to make sure they still accept your insurance, then doublecheck by contacting your insurance plan to confirm they’re in network. 

    How can I book an appointment online with a Small Bowel Bacterial Overgrowth doctor in Massachusetts, US?

    MediFind offers direct scheduling for certain providers using the “Request Appointment” button on that provider’s profile. If the schedule option is not available for a provider, tap the red “Show Phone Number” button on their profile to get their contact information. If you prefer to find providers who offer online scheduling, select “Schedules online” under the “Availability” category of the filter feature on the left side of the Small Bowel Bacterial Overgrowth doctor search results page. 

    Why is it important to get a second opinion from a different Small Bowel Bacterial Overgrowth doctor?

    Second opinions are an opportunity to confirm a diagnosis and its root cause, learn about alternative treatment options, or simply gain peace of mind. Many people, especially those with serious diagnoses, get second opinions so they can understand all their options and make informed decisions, so don’t hesitate to get one if you have any doubts or need more information or clarification regarding your care. Note that some insurance plans require second opinions, while others don’t cover second opinions, so be sure to confirm with your insurance provider first.   

    How can I prepare for my appointment with a Small Bowel Bacterial Overgrowth doctor in Massachusetts, US?

    Prepare for your appointment by gathering the following items: 

    • Copies of medical records (dating back at least one year) 
    • Your medical history, including illnesses, medical conditions, surgeries, and other doctors you see 
    • Family history of disease 
    • List of current prescription drugs, over-the-counter medicines, vitamins, and herbal remedies or supplements including names and doses 
    • Allergies to medications, food, latex, insects, etc.  
    • List of questions and concerns 
    • Your insurance card 

    You might also contact the provider’s office to see if they offer transportation or childcare services or if you’re allowed to bring a loved one for support or to take notes during your visit. 

    What questions should I ask my Small Bowel Bacterial Overgrowth doctor?

    Here are some sample questions: 

    • Can you explain in simple terms what this condition is and how it’s treated? 
    • What symptoms or side effects should I watch for? 
    • What tests will be involved, and when can I expect results? 
    • Are there other specialists I need to see? 
    • What’s the best way to reach you if I have follow-up questions? 

    How can I learn about the latest clinical trials and research advances my Small Bowel Bacterial Overgrowth doctor may know about?

    MediFind’s Clinical Trials tool asks you a series of questions to help you narrow down your search by health condition, age, gender, location, how far you’re willing to travel, and more. Each question you answer filters down the number of trials until you find the ones that are most relevant to you. 

    MediFind’s Latest Advances tool features summaries of recent articles published in medical journals. We use cutting-edge technology to scour medical publication databases for the latest research advancements on any given condition, then we simplify this information in a way that’s useful and easy to understand. 

    Can I filter my search to show male or female Small Bowel Bacterial Overgrowth doctors in Massachusetts, US?

    Look for the filter feature on the left side of the Small Bowel Bacterial Overgrowth doctor search results page. Select “Female” or “Male” under the “Gender” category to search for female or male providers exclusively. If the “Any” option is selected, it will pull results for both male and female providers. 

    Can I filter my search to find a Small Bowel Bacterial Overgrowth doctor that offers video calls?

    Look for the filter feature on the left-side of the Small Bowel Bacterial Overgrowth doctor search results page. Select “Offers telehealth visits” under the Availability category to search for providers who offer virtual appointments (video calls).
