Type 1 diabetic. On humalog and lantus. Inject immediately after meal. However whenever I eat a large meal. Carb count also to equal to the insulin I inject I still occasionally have hypo. Anyone got any personal experience please. Help!! Kally
 
Yes that has happened to me but usually because of too much insulin for the meal or I exercised straight after. Carb counting is never accurate for me. I find its more like carb guessing. Try and keep a note of what you eat and what you inject so you can see how different foods affect your bs. X
 
Thankyou for this info. I will try that for sure. But I am wondering if the time of taking my insulin needs to be adjusted. This happens especially if I have been out for a meal. I dont know if the fat content or protein content delays the blood sugars going up and therefore the insulin is working too quickly?? Just a theory I dont know what to think.
 
It usually happens within the hour. But I find its when I have eaten out at a restaurant. Only at home after a meal if I have had a low GI meal.
 
I note that you inject after a meal. I think many of us inject just before a meal as it takes around 15 minutes to start working. I wonder if injecting before a meal and tweaking your ratio might help a bit due to food absorption rates etc; could make it worse I guess!

I used to up to a few months ago inject just before my meals but it didn't make any difference. I was told by my doctor to inject before my meals too. I keep a diary and watch the blood sugars. Injecting before or after have been making no.difference am afraid. I just keep wondering whether the fat in the food has a part to play in the delay of raising the blood sugars. Also if the insulin is working too soon and causing hypos?
I am wondering if delaying injecting after my meal would help reduce hypos post meals. But I am new to all this and very confused.
 
I am assuming that you test pre meal...? So on these times of hypo's after meals - what sort of example of bg level were you?

It's likely that your over-estimating the carb content of the meal and giving yourself too much insulin when your dining out, it's far better to underestimate the carbs and give a smaller dose rather than go hypo an hour after and spoiling your meal out, if your bg is high on returning home you can always give yourself a correction dose.

Just be mindful of the fat content of food, some restaurant foods (Chinese, Indian and Italian) can be high in fat which slows down the absorption of the food........ meaning your insulin works faster than your food.
 
By this I mean ... Did you have a snack and bolus within 2 hours prior to your random lows.... If you did it could be the reason why you went low... Nothing to do with the meal you wereinjecting or eating for...

This used to happen to me a lot with big restaurant meals, and I was also on Humalog and Lantus (clue that we are both type 1). I think it was a mix of factors. Overestimating the carbs, extra fat in the meal to delay the blood sugar rise, delays in the food arriving at the table, and these were the days when I would inject 15 min before. All those factors compounded and made hypos shortly after starting a restaurant meal a common occurrence.

I now wait until I have eyes on the food before I inject, and I guess I'm just a little more cautious in the quantity I inject. That seems to have done the trick. But maybe it's just my salty sea dog luck.
