I have times where my sugar is high, but I don't have diabetes. I checked it last night and I was very dizzy. It was 130; at other times, it will drop to 74. What should I do?

Are you sure that you do not have diabetes? If your fasting blood glucose is greater than 125 mg/dL, any blood glucose reading is greater than 200 mg/dL, or A1C is greater than or equal to 6.5%, you do have diabetes. Each of these criteria are based on laboratory results and should be confirmed by repeat testing. A blood glucose level of 130 mg/dL can be normal after eating. Hypoglycemia is generally defined by a blood glucose level of less than 70 mg/dL. If you were feeling dizzy and your blood glucose level was 130 mg/dL, the dizziness was most likely unrelated to your blood glucose. If your blood glucose levels are higher than normal, yet not high enough to meet the criteria for a diagnosis of diabetes, that would mean that you have pre-diabetes. People with pre-diabetes can significantly decrease their risk of developing diabetes by eating in a healthy way and exercising or being physically active regularly. For many reasons, It’s a good idea to do these things even if your blood glucose levels are completely normal.
