Diabetes?: Sugar levels are established by complex interplay between many variables. Hard to predict bg level at a random time after eating. If you measure bg levels after eating it is best to check at 2 hours after your meal. At that time bg level should be less than 140. Since I do not see diabetes on the conditions list...A fasting blood sugar >126 on two separate occasions deines diabetes.
