I'm petitioning someone to change the ruddy daft names of these courses, how about "how to use basal bolus", "how to control blood sugar with diet and activity", "how to get the best from mixed insulin regimes" 🙄 In terms of insulin, the basics are the same, insulin resistance might promote some slightly different challenges with timings and doses but essentially the key is you need to work out how much insulin your body needs without food, it needs a certain amount just to keep you alive and upright, so that's the basal insulin. Then there's the amount of insulin your body needs to deal with food. That's trial and error, so lots of people need 1 unit of insulin for 10g of carbs, so you count the carbs in your meal and if it's 50g of carb then you take 5 units (50 divided by 10), we call that a ratio, so that'd be 1:10. You're lucky if you have a 1:10 ratio because it's easy to divide by ten, but you'll likely not be that lucky🙂. Once you've got that sorted the more specific things like timing the dose and how fat levels impact on digestion of carbs come along with practice. The most frustrating bit at first is weighing and reading labels, and looking things up, but you get a feel for it after a while. I promise it really isn't hard, just a bit boring, and a bit like being in maths at school 😱 for a while.
