The use of some statins, such as Rosuvastatin and Atorvastatin, has been reported to be associated with elevated fasting blood glucose and glycosylated hemoglobin. Elevated blood glucose is mainly related to factors such as genetics, diet, poor lifestyle habits, diseases, and medications, and some medications may cause elevated blood glucose, such as glucocorticoid drugs. Statins are mainly indicated for the treatment of hypercholesterolemia. Certain statin drugs may affect glucose metabolism, and there are reports showing that the use of Rosuvastatin and Atorvastatin is associated with elevated glycosylated hemoglobin and fasting blood glucose levels. If you have diabetes or insulin resistance yourself, when taking statins, it is important to test your blood glucose regularly during the use of the medication to avoid high blood glucose. The medication should be taken under the supervision of a doctor.
