For type 2 diabetes or prediabetes, there is a normal blood sugar level that is best 2 hours after eating. We cover the right numbers here. Postprandial levels, or blood sugar levels after meals, are considered normal if they stay below 140 mg/dL . Regular monitoring becomes vital as the risk of conditions like Type 2 diabetes may increase with age. Two hours after finishing a meal, blood sugar levels should ideally return to a relatively normal range. However, it’s important to note that the impact of food on postprandial glucose levels can vary significantly based on your dietary choices, insulin dosage, and individual factors. Blood sugar levels after eating can vary by age, but a reading below 140 milligrams per deciliter (mg/dL) is generally considered normal. In contrast, levels over 200 mg/dL or higher may suggest that you have diabetes. 1
