Who We Are

For over 10 years, the mission of Bariatric Surgery Source (BSS) has been to distill the complex topic of bariatric surgery into easily understandable information for everyday patients.  

Rather than offer general health information across a wide variety of topics, BSS research and content focus exclusively on weight loss surgery.  We offer prospective patients a “deep dive” into the associated risks, benefits, lifestyle changes, and financial consequences of these life-altering procedures.  

Our more than 1,000 pages of content have been compiled by a team of over 20 healthcare, finance, and legal professionals, including board certified bariatric surgeons, registered nurses, licensed dietitians, insurance and employee benefits experts, lawyers, and data analysts.

BSS provides content you can trust so you can be confident in the next steps of your weight loss journey and towards better health.  All content is extensively researched and continually updated to reflect the up-to-the minute “gold standard” consensus among practicing bariatric surgeons.  Further, all health information presented throughout BSS has been thoroughly reviewed by our Advisory Council’s healthcare industry professionals, which includes highly respected bariatric surgeons across the United States, Canada, and Australia.
