When did you have your blood glucose tested? Was it before you ate or after? Actually, personally, I consider 125 very good on either side of eating. Just me.
What was the time when you measured it to be 125? Did you eat anything before testing it?
A bit more information is needed to answer your question. When was that blood sugar taken? Fasting at first thing in the morning? After meals? (How long?). A random blood sugar doesn't mean that much. If it is fasting, then it is in the pre-diabetes category. Normal fasting is considered to be under 100. Pre-diabetes is considered from 100 to 125 and diabetic is considered 126 and over. However one number is just one number and what would be better is to have an A1C done. This gives you an average of blood sugars for a period of about three months. I suggest talking with your doctor, getting an accurate diagnosis and then going from there. If you are determined to be pre-diabetic or to have type 2 diabetes then you can begin to determine a plan to manage your blood sugars. Type 2 diabetes is a manageable condition, but if you ignore it the consequences are quite serious. Managing type 2 diabetes is done with carb reduction, weight loss if needed, exercise and oral meds if your doctor determines this is needed. If you are pre-diabetic it's a good opportunity to get your blood sugar under better control to prevent or slow the progression to diabetes. Worrying doesn't serve much purpose, but getting a clear picture and determining action does!
