Dear LABS Participants,

We welcome you to our newly revised website and thank you for your continued participation in LABS. We hope you find this site to be a valuable and useful resource to keep abreast of the study as well as to help you on your bariatric surgical journey. We would be most interested in any comments and suggestions you might have for additional features that we should consider.

Thank you,
