Glycated hemoglobin of 11.8% in diabetics is above the control target and is more serious. Glycated hemoglobin in diabetic patients should generally be controlled below 7%. Glycated hemoglobin reflects the average blood glucose level in the last 2 to 3 months. Glycated hemoglobin of 11.8% is much higher than 7%, suggesting that the patient’s blood sugar level has been higher in the last 2 to 3 months. Long-term poor control of blood glucose levels in diabetic patients is likely to lead to various complications such as diabetic retinopathy, diabetic nephropathy, diabetic neuropathy, diabetic ketoacidosis, diabetic hyperosmolar hyperglycemic syndrome, etc., and therefore may be more serious. Diabetic patients who are found to have a glycated hemoglobin of 11.8% are advised to seek prompt medical attention to avoid delays in their condition.
