Usually 1-2 hours : Checking blood sugar after meals gives important information on the effects of your food choice on your sugar levels, as well as the effectiveness of any diabetes medications. Many experts recommend targeting <180 mg/dl at 1-2 hours after meals in diabetes patients. This time interval gives the peak glucose levels of the day. If you can control these, then your overall hba1c will be in range!

2 hours: Check blood sugar 2 hours after eating for a post prandial value. Fasting blood sugar is usually checked 8-12 hours from the time the last food was consumed.
