Dr. Chiasson believes that the newly evolving field of Endo-Bariatrics is poised to play a significant role in the management of obesity.  According to a recent article in The New England Journal of Medicine article, 50% of American adults will have Class I obesity – defined as being more than 50 lbs overweight by the year 2030. Endo-Bariatric procedures may help to bridge the treatment gap for individuals who are fearful of invasive bariatric surgery.   

In 2020, The American Society for Gastrointestinal Endoscopy (ASGE) published recommendations for the use of Endoscopic Bariatric Therapies in order to provide guidance for this evolving field.

Who is a Candidate for an Endo-Bariatric Procedure?

Patients with a BMI of 27-50 who have failed weight loss or weight maintenance with lifestyle intervention.


What Screening Testing is Required for an Endo-bariatric Procedure?

  1. Medical pre-procedural consultation.
  2. Dietician Consultation with attention is focused on the patient’s diet history, nutrition status, eating patterns, and post-procedural diet guidelines.
  3. Routine laboratory testing for CBC, Complete Metabolic Panel, and Nutritional Screening.


What is the Post-procedural Maintenance program?

Patients are expected to participate in a Weight Loss Program that focuses on caloric restriction, exercise, and long-term follow-up to address both weight loss maintenance and potential procedural and nutritional long-term complications.


In 2016, more than 1.9 billion adults, 18 years and older, were overweight. Of these over 650 million were obese.
