Living with Type 1 diabetes, and making the correct decision on insulin needs, is like living everyday in a chess game. One moves determines the next move, and there is always waiting involved.
People with Type 1 diabetes receive insulin to live. The two kinds of insulin they use are basal and bolus. Basal insulin is the background insulin that is released into their body a tiny bit every few minutes. This is either through a basal insulin like Lantus given through a shot once every 24 hours, or through an insulin pump that delivers fast acting insulin every few minutes. How much insulin that is needed is determined through numerous factors such as weight, age, and time of day to name a few. The best way to determine how much basal insulin is needed is to log blood glucose values throughout the day when the person has not eaten any carbs. Not eating carbs allows the person to use only basal insulin. So if the numbers go up without eating the person knows they need more basal at that time, if the numbers go down without receiving any extra insulin then the person knows they need less basal insulin. See what I mean about a chess game?
Every decision on how much basal insulin depends on something else. If my son goes too high after not eating for several hours then I can determine that he needs more basal insulin at that time. I make the change, then I wait. I wait until the exact same time the next day, make sure he doesn’t eat again, and check his sugar to see if it remained stable thereby telling me that he is getting the correct amount of insulin for that time of day.
Basal rates are different for some people at different times of day. My son currently has 7 basal settings in his pump. He gets an enormous amount of insulin from 8:00pm to midnight and then is drops off and then remains even all day. The only way I was able to figure out the best basal rates for him was to test, make changes, wait, make more changes, etc.
People without Type 1 diabetes who have a working pancreas also receive a basal insulin. They don’t know about it, but the pancreas is working hard for them determining how much basal they need in order to remain an even blood glucose value. That is why they don’t have Type 1 diabetes, their pancreas can do that for them.
The second type of insulin that people with Type 1 receive is bolus. This is a fast acting insulin that is given any time carbs are eaten. This is usually give in the form of a ratio. For instance, my son now gets 1 unit of insulin for every 16 carbs that he eats at breakfast. The rest of his meals are different ratios. The only way I can determine if my son is getting the proper amount of insulin at meals and snacks is to test him 1 hour, 2 hours, 3 hours, and 4 hours after eating. You always look to get the best number possible for each time frame. This is where the waiting really takes place. It may take days to figure out one meal ration. If on Monday, my son’ number is too high at testing times after breakfast, the only way I can fix it is to change the ratio for Tuesday. If his number is too high on Tuesday at the testing times, the only way I can fix it is to change the ratio for Wednesday. Do you get what I saying. Waiting. Changing. Waiting and so on.
Now, I have to do this for 6 separate times a day over the course of several days. My son has different ratios for different times of day that he eats. Lots of testing, note taking, changing and waiting helped me determine what are the best ratios for my son at different times of day.
One move relies on the next. It is just like a chess game. You are always waiting to see what the previous move is going to do to the game. One change in breakfast ratio may have an effect on the snack ratio and so on. It is never ending. Like I once said before, living with Type 1 diabetes is like running a marathon that never ends. Well, it is also like playing a chess game that never ends. You are always waiting on your opponents next move to determine where your next move is going to be.
