hi sorry dont know your name but thank you for answering, my long lasting insulin is lantus. i went on the carb counting course but i am not well educated to which i am embarrased , and did not understan and was tottaly confused, i was told to keep upping it by 2-1 ratio that bit i do understand. but 2 hours later i check blood which still seems high i do the same thing again and end up having an hypo which really drains me , that is the bit i do not understand as i didnt know how long they take to wear off, thank you once again as really appreciate the help i also have support at the hospital and they just say i need to carb count which is the bit i dont know and understand,
Hi Martyn, welcome to the forum
🙂 You shouldn't inject more insulin if your levels are high two hours after eating, as the insulin you injected with your meal will still be working in your system to bring your levels down - more insulin will bring levels down too much and you will have a hypo, as you are discovering
Using a fast-acting insulin it is often a matter of timing. When you inject and then eat, your food starts digesting and raising your blood sugar levels, but your insulin may be a bit slow to catch up with this. As a result, after two hours your food is probably fully digested, but your insulin hasn't quite caught up with it, so your levels may be high at this point. However, as the insulin continues working for about 4-5 hours it's quite likely that, after 4 hours, and with no extra insulin, your levels will be much better. I would suggest trying this and seeing what your levels are like at two and 4 hours - don't worry for now if your levels are a bit high at two hours, just wait and see where they are at 4 or 5 hours.
In time you will build up experience of how your body reacts to your different meal choices, and be able to improve timing your insulin injection so that the insulin is 'peaking' at around the same time as your food. This will take time though, so try not to be too concerned about seeing higher levels after two hours for now

Do speak you your nurse and ask her to explain again how things work - it can be very complicated, so don't feel you ought to be able to understand everything - if you're not sure, keep asking questions until it starts to make sense to you
