Default Testing Guidelines?

I'm in the process of setting up some guidelines for myself to test my blood glucose levels at various times. I'm specifically interested in my blood sugar after eating certain foods. From what I can see around the web, all references seem to say 2 hours after a meal. Is that right. If I am testing the effect of certain foods on my blood sugar then should I always wait 2 hours? I actually don't have diabetes (diagnosed) but definitely do have hypoglycemic episodes.

Here are the times I want to test myself with my new blood glucose monitor. Can anyone correct / comment on my approach. Should I be testing in mg/DL or mmol/L ?
I'm in Australia.

What ranges should I use. After a meal, what is normal for a non-diabetic? When fasting what is normal for a non-diabetic?

1 - Before breakfast (fasting blood glucose levels) 6-8 mmol/L
2 - After meals (2 hours) but more specifically, after certain foods. 6-10 mmol/L
3 - Before bed.
4 - When I have a hypoglycemic episode.

I'm not necessarily approaching this from a diabetic's perspective but I do want to work out what is giving me bouts of hypoglycemia. I suspect that I have a sensitivity to animal proteins (long story). Can anyone add some reasoning / improvements to my above approach?

Thanks

A good understanding of the body's glucose metabolism will help in determining when you should test. When a food is eaten, the carbs are digested first and glucose enters the blood stream quickly - usually peaking at about one hour. A non-diabetic also introduces stored insulin to cover this, but a diabetic, with a poor 1st phase insulin response may not provide any, or very little, insulin for this.

So, usually we test at the 1-hour mark so that we can catch the spike and thereby know how much a certain number of carbs will raise our BG.

In response to higher BG the pancreas then begins to make new insulin, the 2nd phase insulin response. This takes longer and doesn't begin to affect BG until about an hour after eating and it can take another hour for this insulin to bring BG down.

We test at 2 hours after the first bite to determine if our BG is going down. Now this is where other factors influence the outcome - fats can slow digestion, as well as eating large meals, one may have a good or poor 2nd phase, and a host of other variables.

The testing method that works well for diabetics is in detail here: http://www.diabetesforum.com/diabete...ng-method.html


Re: hypoglycemia. I had this for many years. The best way I found for eliminating the roller-coaster BG ups and downs was to not let BG go up in the first place. LCHF works well in keeping BG low and stable.

My understanding of hypoglycemia is that the pancreas, in response to high BG, will over-produce insulin - hence the fast "crash" of BG - and the awful feelings that produces.

From Blood Sugar 101

What is a Normal Blood Sugar?

Quote:
Post-Meal Blood Sugar (Postprandial)
Independent of what they eat, the blood sugar of a truly normal person is:

Under 120 mg/dl (6.6 mmol/L) one or two hours after a meal.

Most normal people are under 100 mg/dl (5.5 mmol/L) two hours after eating.

I do a 1 and 2 hour test on new foods, particularly fruits, which are absorbed quickly. If I'm way over 200 at one hour, I have to decide to exclude the food, combine with a protein or fat, or reduce the portion size. Very often, fruit results in a normal reading after 2 hours, so I would not have known.

@Bunjee

You'll find the most of us are not willing for our BG to go above 140 at anytime. It is above that level that organ and nerve damage begin, so that's why we work hard to keep our BG below that.

See the link to "Eat to your meter" in my post, #3, above.

Yeah, fructose doesn't always (and often doesn't) show up terribly on our meters, but is not a great choice for diabetics due to it being implicated in insulin resistance.

I agree with you, but someone first starting out after diagnosis shouldn't be shocked into throwing up their hands and saying "I can't do this". Make a goal to FIRST address those things that send you over 200 - then work on the other stuff as time goes on.

Currently, due to steroids, I can't even eat lettuce or green peppers without sending my blood sugar well above 140 for a while at least. I'm unwilling to give up vegetables in favor of cheese - my digestive system can't take it.
