According to the American Diabetes Association, two hours after the start of a meal, blood sugar levels should be less than 180 mg/dL for adults with diabetes. For adults without diabetes, blood sugar levels should be less than 140 mg/dL two hours after eating. However, it is important to note that blood sugar targets may vary depending on age, additional health problems, and other factors, so it is best to talk to a healthcare team about which targets are best for an individual. It is also important to note that blood sugar levels can vary depending on what is eaten and how much insulin is dosed, so it is important to consult with a doctor or healthcare team if there are concerns about glucose levels.
