My 12 hr fasting blood sugar is 105 mg/ dl today. it is always normal 4yrsago. im in a lot of stress and eating lot of sweets. diabetes?

Stress,,: This is a normal blood sugar. The range of fasting blood sugar for adults is from 70 to 110 mg/dl and varies depending on the laboratory. If it's been higher, stress and sweets can be a very likely reason, especially if you're diagnosed as a type 2 diabetic. But this sugar is normal, so it'd be wise to see your doctor and get reevaluated, and also stop some of the sweets and stress. Good luck.
