Question: why do sglt2 cause ketoacidosis?
Answer: SGLT2 inhibition lowers the renal threshold for glucose excretion, resulting in renal glycosuria, a shift in substrate utilisation from carbohydrate to fat oxidation and hyperglucagonaemia; this poses a theoretical risk for ketoacidosis (including euglycaemic ketoacidosis) in the presence of other precipitating factors ...
