SLC5A1 and Hyperglycemia: We hypothesized that canagliflozin, a sodium-glucose cotransporter 1/2 inhibitor, would reduce postprandial hyperglycemia and hypoglycemia.<h4>Case report</h4>Retrospective analysis was performed on continuous glucose monitor data of 4 patients (3 females and 1 male) with PBH from Roux-en-Y gastric bypass who took canagliflozin 300 mg daily.
