Depending on whether blood sugar levels are measured on an empty stomach or after a meal, they vary between 3.3 and 7.8 mmol/L (about 60 and 140 mg/dL) in healthy people. There are no clear-cut boundaries between the normal range of blood sugar and high or low blood sugar.
Why sugar level is high in empty stomach?
1The sugar in food is absorbed into the blood as glucose. 2The pancreas secretes insulin in reaction to the increase in glucose. 3Because the glucose is absorbed into the liver, muscle, adipose (fat) tissue and other cells, the blood sugar level drops to the level it was before anything was eaten.

Is 220 too high for blood sugar?
Blood glucose is commonly considered too high if it is higher than 130 mg/dl before a meal or higher than 180 mg/dl two hours after the first bite of a meal. However, most of the signs and symptoms of high blood glucose don’t appear until the blood glucose level is higher than 250 mg/dl.
Is 240 blood sugar too high?
