It will be interesting for you to take a look at how they work for you. The ‘baseline’ suggestions you have been given
1u = 10g carbs
1u = 3mmol/L drop in BG
also generally have an expectation that
10g carbs = 3mmol/L rise in BG
But these are just general guides, and part of improving your diabetes management involves a bit of experimentation and seeing how those are actually working for you in practice.
For instance... you may discover that at breakfast for you
1u = 8g carbs or...
1u = 12g carbs
Which is not quite so easy to work out in your head! But if you generally eat the same breakfast each day you can do the sums on a calculator and just use that dose
