Sugar vs Carbs
 
Hi there. So there is one thing that I don't really understand after all of this time having diabetes (I guess I never really thought about it before) and It's the difference between sugar (high glycemic index) and low GI carbs.

Doctors always told me that "slow" carbs act slowly on your glucose levels and mantain it up there for a longer period of time, while sugar makes it go up really fast and then goes down again fast.

But my question is. How that does happen and what does it mean when I read the nutritional facts table. I'm gonna put an example to be more clear.

If I check my Blood sugar level before going to sleep and it's at 90 I should probably eat somethng.

Case N1: I eat a some pasta (low GI) and I see that it says "30g of carbs" for the amount that I'm eating.

That should slowly bring my BGL to around 180 and slowly bring it down until I get up. Something like this maybe:

Case N2: I drink a can of orange juice and it says "30g of carbs" for the amount I'm drinking. That should get my BG to around 180 really fast and then bring it down fast too. Something like this?

In both cases (in the long term) I should wake up with the same BG, only one brings it up and down faster than the other one?

I'm pretty sure this is not correct, but please explain it to me because I can't get around it.

Does this means that if I want to eat 30g of pasta or 30g of juice and "correct it" (carb counting) I should use different doses even though both are 30g of carbs?

Thanks in advance and I apologize for the long post.

I think you have it olmost correct. I think the area under the curve is the same for orange juice and pasta (30gr each) I thingk the pasta will raise BG over a longer time but not as high, so you might go to 150 for hours with pasta.

Ok. This is a new concept for me. Are you saying that there is a formula that I can use to know just how many points my BG will rise if I eat a certain number of carbs?

I don't think I've ever seen or heard of one, JohnCA. The only way I know how much X amount of carbs raise my BG has been by testing. And that "formula" changes with the makeup of the meal.

Every one is different some still make insulin some dont some make more insulin some less. some have more insulin resistance some have less. You need to to measure, eat, test and make your own formula.

Well, like they said, after some time trying you can get an idea.

When I'm high, I use 1 unit of fast insuln (humalog) to decrease 40mg/dl of my BG. On the other hand, when I have a meal, i use 1 unit per 15g of carbs. So from that, I can say tat 15g of carbs will raise 40mg/dl. But as they said, it depends on a lot of factors, and my question on this topic was aimed to understanding how I should take into account different types of carbs.

Right, that's what I thought. Here's what happened: I was really full and I didn't feel like eating. I checked my BG and it was at around 90 (I usually go to sleep at 180 to avoid hypos) so I said to myself: "Since I don't feel like eating at all, I'm just gonna have Coke" Knowing that wasn't the ideal thing to do because it was gonna get my BG up fast, but I thought it was gonna come down eventually and get me through the night. Well it didn't, I woke up with hypo and my doctor explained this to me.
But then thinking about it I got really confused. Considering that for, lets say 15g of carbs, different foods will raise your BG at different times and will last for longer or shorter times. How do you quantify that to inject the proper amount of insulin when you have a meal??? :vs_worry:

There's where injected exogenous insulin and what your pancreas puts out differ. The amount of and the times that your pancreas puts out insulin are regulated by what your body senses. There are what's called 1st phase and 2nd phase insulin secretions, which I think are simplified as an expression to explain that. I think your pancreas regulates insulin constantly to keep your BG at a workable level in what we call a "normal" non-diabetic.

In order for you to do that existentially you would have to have an artificial pancreas that constantly sensors BG and injects insulin accordingly. Where we stand now, with mathematical formulas and single bolus injections...you're just gonna have to wing it.

Experience!
Im sorry the truth is we ALL have varying insulin resistance, working pancreases. witch results in varying responses to food/carbs/sugar. its a ***** but keep good records and it will help.

as an example. I found that I have to bolus 30 minutes before I eat. els the food raises my BG before the insulin starts to work. I would end up with BG going to 180 to over 200 the after 4 hours being back to base line. If I counted correct and injected 30 minutes before my BG never went over 140 and never went low. (depending on what I eat)

Thank you all for your replies. I guess there are so many factors influencing BG that it's impossible to take all of them in to account. I'm not doing so great on my levels, so I thought that maybe this could be one factor that I wasn't considering that could make it better. But i guess I'll try to focus more on other aspects.
