Diagnosis and Symptoms, Other

Question from Richmond, British Columbia, Canada:

How long does it take for simple sugars, like sucrose, to reach the blood stream and affect the person? What would be deemed a high blood sugar level?

Answer:

If simple sugars are eaten, they would be broken down rather quickly and take about 10 to 15 minutes to raise the blood glucose levels. It’s the same for stimulating insulin release from a person without diabetes. If the simple sugars are also ingested with protein, and more importantly with fats or complex carbohydrates, then stomach emptying is slower, therefore, absorption is delayed accordingly.
