Summary

The lay summary the sponsor registered on ClinicalTrials.gov.

The goal of this pilot clinical trial is to determine the effectiveness of Tirzepatide in patients with persistent obesity (BMI \> 30) 12 months after bariatric surgery (Roux-en-Y Gastric Bypass). The investigators also aim to determine the frequency of side effects with Tirzepatide in this patient population. Patients who take tirzepatide 12 months after bariatric surgery will be compared to patients who continue with the current standard of care for patients who have previously undergone Gastric Bypass Surgery.
