Dear editor,
Sodium glucose co-transporter 2 inhibitors (SGLT2I) reduce the majority of reabsorption of glucose in the proximal tubules, which reduces blood glucose levels by allowing excretion of excess glucose in the urine.[1] By inhibiting glucose reabsorption, they increase the osmotic pressure of urine resulting in diuresis which can cause a reduction of blood pressure.[2] Fortunately, as these drugs are not directly implicated in altering glucose metabolism or causing insulin secretion, SGLT2I monotherapy does not result in severe hypoglycemia.
