The potential for elevated blood sugar exists with almost all statins, just the risk of it occurring varies with the type of medication, and patients who need to take the medication are advised to consult their doctor. Statins work by lowering total cholesterol and lowering triglycerides, and include such different types as atorvastatin, simvastatin, lovastatin, fluvastatin, pitavastatin, pravastatin, and resuvastatin. Usually, the adverse effects of statins include rhabdomyolysis, liver dysfunction, jaundice, and abnormal glucose tolerance. Therefore, patients should pay special attention to the fact that if they are taking statins, they should always keep a watch on their health condition and go to the hospital for regular checkups to monitor their blood glucose and glycated hemoglobin levels, and then make timely adjustments to their medications under the guidance of their doctors.
