[QUOTE="In Response, post: 2396634, member: 527103"] We digest different foods at different rates. This is obvious when we hypo - we take fast acting carbs. Some fatty foods (such as pizza and curry) are very slow acting. However, injected fast acting insulin works at the same rate regardless how much we inject and what we eat. If you Google something like "NovoRapid profile graph" you will see the speed at which NovoRapid works over time - it has a peak and lasts for 4 or 5 hours. Ideally, we want to match the peak of the NovoRapid activation with the peak at which the carbs that we have just eaten are digested. Assuming we carb count correctly, the only variable we have to adjust is when we inject. If your son is hypoing after eating and his insulin to carb ratio is correct, he may be taking his insulin too early for the food he is eating so you could try delaying his insulin until after he has finished ... or just before he eats rather than 15 minutes before. As with everything diabetes related, we are all different so it may take some trial and error to find the best timing for your son's dose. [/QUOTE]
