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. You have two options:
- 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.
- Increase your usual dose of fast acting insulin 15–30 minutes before your meal by an amount agreed with your healthcare provided.
