Cluster analysis for classification of patients submitted to Fobi-Capella bariatric surgery.

Background: Individuals classified as morbidly obese require effective treatments to promote weight reduction. Due to the inefficacy of conservative treatments and current medications, bariatric surgery (gastric bypass) has been indicated for this group of individuals.

Aim: To identify subgroups of obese patients in order to find patterns that hinder weight loss and recovery after the operation.
