I am embarrassed that after 25 years I do not know what basal and bolus mean. I don’t know what the profile is of my insulin’s, what ketosis means, nor what 'diabetic ketoacidosis' means either.
Where can I go to learn more about the mechanics of my diabetes, where can I get a constant message of what I should be doing? Because at the moment, I haven’t got a clue!
as Sandra says, don't be embarrassed. It's not your fault.
I don't know if you actually are asking the questions wanting answers but in case you are here are the answers:
- basal insulin starts to work slowly and usually lasts in the body up to 18 or even 24 hours. Some examples are Lantus and Levemir (the brand names). Your liver stores sugar, and releases little bits of it during the day to keep you going - kind of like a 'base rate' of sugar release, which is why they call it basal or background insulin. You inject basal insulin to deal with this background drip-drip of sugar.
- bolus insulin starts to work quickly (within 10 mins for some types) and lasts in the body only about 4 hours or so. Some examples are Humalog or Novorapid (the brand names). When you eat food that has carbohydrate in, like bread, pasta, potatoes, rice, and most fruits, your body breaks the carbohydrate into sugar. The sugar goes into your blood in a big rush (a 'bolus'). The bolus insulin is intended to deal with this sugar from the food you've eaten. So, you might eat a chip butty and need lots of bolus insulin, or eat a chicken salad with no carbs and you wouldn't need to inject bolus insulin at all.
- the 'profile' of your insulin is basically how quickly it starts to work and how long it lasts. Which ones do you use?
- if your body can't use the sugar in your blood (and it needs insulin to use it) then it thinks it is starving and starts to break down fat cells. A by product of that is ketones, which enter the blood and can make you ill. This is called diabetic ketoacidosis or DKA. It can lead to coma.
does that help? Sorry if you already knew it. Please ask other questions, if anything seems unclear. It's the most complex disease I know if, in terms of learning how to self manage, so don't ever feel ashamed about not understanding something.
From reading stuff on here I think most of the Type 1s are fairly constant in the way we manage our diabetes - carb counting and so on as others have described - so do use this site as a resource.
