Summary:

      Th mechanism of action of dapagliflozin is via sodium-glucose co-transporter 2 (SGLT2)
      inhibition. Sodium-glucose co-transporter 2 inhibition is associated with moderate weight
      (fat) loss, in addition to other health benefits, including decreased blood pressure,
      decreased inflammation, and decreased oxidative stress. It is unclear as to whether these
      health benefits are due to SGLT2 inhibition per se, or as a secondary effect of weight loss.
