I have diabetes, how do I lower high blood glucose before a meal?

High blood glucose before a meal tells you that your liver is making too much glucose and needs to be told to slow down! The signal it needs is insulin. Because it takes time for insulin to be absorbed from the skin and additional time to reduce the liver's glucose production, we suggest that you take your usual dose of insulin and wait 60–90 minutes (instead of the usual 30–45 minutes) to eat. This will allow your blood glucose level to fall toward the normal range before you eat, giving the insulin a "head start." The goal is not to become low before eating but to regain control over high blood glucose. An alternative is to take lispro insulin 15–30 minutes before your meal, which should lower your blood glucose more rapidly than regular insulin.
