Study Groups

Review each arm or cohort in the study, along with the interventions and objectives associated with them.

Cohort 1

Cohort #1 (within-subject) will enroll up to 10 women with class III obesity who plan to undergo Roux-en-Y metabolic and bariatric surgery as a standard of obesity care. Subjects will complete study measures preoperatively and one year postoperatively.

Metabolic & Bariatric Surgery

Intervention Type PROCEDURE

Roux-en-Y metabolic and bariatric surgery

Cohort 2

Cohort #2 (between-subject) will enroll up to 10 women with a history of class III obesity who underwent Roux-en-Y metabolic and bariatric surgery as a standard of obesity care approximately one year before enrollment. Subjects in this cohort will be matched on demographic and clinical variables to those in Cohort #1.
