T1’s and T2’s do have different terminology sometimes… I’m still learning alot about T2 from the folks on here and T1 always seems to hold a surprise or two
A CGM is a Continuous Glucose Monitor. It uses a sensor that you insert under the skin to monitor your glucose levels and daily patterns.
A bolus is the amount of insulin taken to cover a meal or a snack so your blood sugars don’t rise too high. If your sugars get too high, you can lapse into Diabetic Ketoacidosis (DKA). This is where your body can’t utilize the sugar in your blood (not enough insulin) so it starts consuming other things to keep you alive. Ketones are a symptom of DKA and can be tested for with a simple urine test. DKA is very dangerous, esp for a T1, as it can lead to coma and death if not treated in pretty short order.
Insulins… there are lots. Short acting is what T1s take with meals to cover the food intake (this is a bolus). Long acting is what we call a basal insulin. Even while sitting down doing nothing, our body still releases sugars into the blood stream for fuel. This basal insulin helps keep our blood sugars in control between boluses. Without a basal insulin, a T1s blood sugar may rise by 1 point a minute and could rapidly lead to DKA resulting from the high blood sugars. Of these two basic types of insulins there are several specific brands made by different manufacturers, and while the basic characteristics of each insulin may be similar, different individuals may respond differently to each. It’s a matter of finding the one that works best for you. There are also insulins that combine a fast-acting and long-lasting insulin to reduce the number of shots required.
What a pump does is try to simulate what the pancreas normally does and we try to accomplish with our various injections. It releases a constant amount of insulin (basal) throughout the day and allows us to take a single larger dose (bolus) with meals or to correct a high blood sugar level. One thing to note here, is that the pump is filled with a fact-acting insulin as opposed to a long-lasting one, this allows for much tighter situation control. On my pump, I have 4 different basal rates set for various times of the day. For example, I need a lot less basal insulin over night when I am asleep than I do during the morning ours. It also has a “bolus wizard” that helps me calculate how large of a bolus I need based on how much insulin it takes to effect every carbohydrate consumed (carb ratio), how many carbs I will be consuming and what my current blood sugar level is.
I hope I helped a little
