The body is very good at soaking up any blood sugar in the urine back into your bloodstream. A protein located in the kidney called SGLT-2 (sodium glucose transporter) helps do this.
Jardiance is a type of drug called a SGLT-2 inhibitor. That means it blocks this protein, so glucose leaves your body through the urine, lowering your blood glucose level. The amount of glucose that is removed from the body into the urine with Jardiance treatment is about equal to 40-50 sugar cubes a day.
