What would be an acceptable blood glucose reading for a type 2 diabetic approximately 2hours after eating a meal? I have discussed this with several doctors, and their answers differ. They all agree on keeping ones a1c below 7 to cut down the chhances of diabetic complications, but there seems to be a wide range of differences with doctors concerning safe and healthy blood glucose levels. Curious to know your opinions and advice.

Yes. There are some differences in opinion on the acceptable blood glucose readings for 2 hours after meals – for a person with type 2 diabetes. There are several endocrine organizations that have guidelines for blood glucose control. AACE (American Association of Clinical Endocrinologists) recommends a 2-hours post-meal glucose of under 140. Joslin Diabetes Center and the ADA (American Diabetes Association), on the other hand, recommend a peak post-meal blood glucose level (1-2 hours after the beginning of the meal) of less than 180. Most of the scientific evidence supports a post-meal blood glucose of less than 180 as a goal, although some would argue that lower (less than 140) would be ideal. At the present time, I would recommend 2-hour glucose of less than 180 mg for most individuals. Also, it is important to emphasize that blood glucose goals need to be individualized. This is especially true in older adults and individuals with other serious medical problems.
