Hi - sorry if this is an obvious/daft question. I've often wondered is it harder to bring sugars up if I've gone a bit low 1 hour after eating and do other people find this a problems at times? Tonight I'm down to 4.1 BSs 1 hr after eatng and taking my bolus to cover the carbs (the reason why ive gone lower i don't know as last night I was 12.2 after food!!)

My question is -is it harder for the glucojuice to work because of the last shot of insulin to cover the food? I struggle to get them to come up to a reasonable level quickly (can take 30 mins+) whereas if I go a bit low 3/4 hrs after food my BSs shoot up quite quickly - within 10 minutes. I suppose I just want to know is is to be expected?

I suppose the simple answer is 'yes'! 3-4 hours after your meal and bolus, the bolus is wearing off so if you have a hypo then, you're not battling against the active insulin also. Whereas within an hour you still have a lot of active insulin on board :)

Thanks - just wanted to put my mind at ease that I wasnt different in this respect. Hypos - oh how I hate them :thumbdown:

Well, no. 15g glucose from Glucojuice will result in a nominal increase of 3-5 mmol/l - way more than insulin would compensate for.

The real reason is that glucose is absorbed in the small intestines, which means it has to pass through your stomach first. When your stomach is empty, liquids like glucojuice will pass through it very quickly, but you've just eaten...

If you don't believe me, have a 4 bottles of glucojuice* and take insulin to cover the amount of carbs. You'll find that BG will increase very quickly before it comes down slowly.

* 60g glucose, which I think is the standard amount.

Even harder to get back up if the previous meal was high in fat. I was advised in these circumstances to drink a small can (150ml) of coke, apparently the carbonated nature of the drink helps to empty the stomach faster and gets the glucose into the system quicker, don't know how true this is so hopefully someone may explain further.
