Also, regarding glucose levels, it was discovered that individuals with diabetes type II reabsorbed more glucose via the kidneys then non-diabetic individuals. This means that there is another cause on blood glucose control increase in individuals with diabetes.
There are different mechanisms for this reabsorption and in the case of glucose, the mechanism that is in charge of its reabsorption is called SGLT-2. Now, as reported before, the group of medications this article is focused on get rid of the glucose excess by inhibiting the SGLT-2. If the glucose is not reabsorbed by the body, it’s going to be eliminated along with other urine compounds and water. This is why the generic name for this group of tablets is SGLT-2 inhibitors.
