There are several things you can do to help avoid high blood glucose levels after meals if you are on insulin:
  • Give yourself a pre-meal dose of fast-acting insulin about 20-30 minutes before you actually eat. You can give yourself about 30-40% of what you think you will need for that meal and then the rest later. This pre-meal amount, or bolus, is called “priming the pump.” It has been shown to really limit the post-meal blood sugar spike. If you wear a pump it is quite easy. However, if you are using an insulin pen you will have to give yourself two injections for the meal. 
  • Try to limit the amount of rapid-acting carbohydrates in your meal. This may be hard to do, but definitely cut out drinks with a lot of sugar calories. And, no fruit! 
  • Spread out your calorie intake as best you can. I know this seems like a pain but eat slowly and, if you can, save part of your meal for later as a snack. Mixing your rapid-acting carbohydrates with fat and protein can help as well. 
  • Try Afrezza, the inhaled insulin. It has a rapid-on rapid-off course of action that helps limit how high your glucose goes after eating. It also reduce your chances of having a delayed low blood sugar (hypoglycemia) reaction.
