SGLT2 Inhibitor Effects on Inflammation and Heart Disease in Obesity Pilot

Obesity is associated with increased cardiometabolic disease risk due, in part, to heightened chronic inflammation arising from adipose tissue. There are no current targeted therapies to prevent or reverse the chronic inflammation of obesity, and a better understanding of these inflammatory pathways in humans is key to future therapeutic interventions. This project will determine both the anti-inflammatory potential of the SGLT2 inhibitor empagliflozin, and the contribution of adipose inflammation to surrogate measures of cardiovascular disease in a randomized controlled trial of obese patients.

This study will be expanded to include another 10 participants. Enrollment will begin July 1, 2023.

Eligibility Criteria:
Inclusion criteria:

3. BMI ≥ 30 kg/M2
4. The ability to provide informed consent
