Indeed it does.
Bolus timing in relation to your pre-meal blood glucose value will greatly effect your post-meal blood sugar value. In addition, you may wish to consider how quickly the food you will be eating is absorbed. One way to determine this is by referring to the Glycemic Index.
|
Bolus timing in relation to meal |
High GI / Fast (>70) |
Moderate GI / Average (56–69) |
Low GI / Slow (<55) |
|
BG above target |
35–45 min. prior |
20–25 min. prior |
Correct the high BG 20min before the meal and start the meal bolus at the time of the meal |
|
BG within target |
20–30 min. prior |
10–15 min. prior |
15 minutes after meal starts (or use dual wave bolus) |
|
BG below target |
0–15 min. prior |
5–10 min. after meal starts |
20–30 minutes after meal starts (or use square wave bolus over 1 hour) |
Sample foods as measured by the Glycemic Index
| High GI (Fast) | Moderate GI (Average) | Low GI (Slow) |
| Breads/Crackers | Fruit | Pasta |
| Salty Snacks | Juice | Legumes |
| Potatoes | Pizza | Salad |
| Rice | Soup | Veggies |
| Cereals | Cake | Dairy |
| Sugary Candies | Chocolate |
