Default Correct time to take readings

I'm new to this and still trying to figure out how the sugar levels raise and lower, what is normal as far as rising glucose after eating etc.

From what I gather, glucose rises after eating. that is normal. Then if you are normal (not diab or pre), it should drop.

I am unsure whether the highest level is directly after eating, or two hours after. Or when the levels are supposed to drop to be considered normal.

I found this advice online from another poster of a diabetes website.... and wonder if anyone has any thoughts on it....

Quote:
"Average Daily Blood Sugar" is a meaningless term.

You blood sugar varies, depending on WHEN, WHAT, and HOW MUCH you ate.

So the goal is to have NORMAL blood sugars at certain well-defined times in the day. The AVERAGE is not important.

The FIRST reading to take is just before breakfast. This is called a FASTING READING, because you haven't eaten for 8-10 hours (because you've been asleep).

The FASTING READING should be a a little lower than normal, in the range of 70-100. But a reading of up to 120 is OK.

The next TWO readings are taken just before lunch and just before dinner. THESE reading should be normal - 80-120.

The fourth reading is taken just before bed. again, this reading should be normal, 80-120.

SOME doctor ALSO ask you to take readings TWO HOURS after eating. THESE readings should be slightly high, like 130-180.

NEVER TAKE A READING AT ANY OTHER TIME! Readings taken at the wrong time are meaningless and confusing.

NEVER EVER take a reading any sooner than TWO HOURS after eating. This reading WILL be high, and it may lead you to believe you are diabetic when you are not.

The ONLY readings that are important are:
1) Just before meals (normal, 80-120)
2) Just before bed (normal, 80-120)
3) Two hours AFTER the meals, IF the doctor ask for it. (slightly high, less than 200)

AVERAGE readings are NOT important. NO doctor uses an "average daily blood sugar" number.

Now, there is a test called A1C. This test takes an average of all your blood suagr readings for the LAST 90 DAYS. THIS rading is important, but it's value is different than a normal blood suagr reading. ONLY a doctro can do this test.

A NORMAL A1C reading is between 5 and 6 (percent). Any reading more than 7% indicates that you are diabetic. The higher the number (8, 9, 10 . . . .) indicates how badly the diabetes is out of control.

- - - -
Based on what you have written, you DO NOT seem to be diabetic. but you DO need to take the A1C test. ASK your doctor for it, and INSIST that you get it. the A1C test is the State-of-the-Art in diabetes testing, and it catches all those "highs" that the Finger Stick method misses.

If the A1C test is "normal" (5 to 6) then you are NOT diabetic, not even "pre-diabetic".

On the subject of when to check your figures I've not really beaten the ideas here - How to Lower Your Blood Sugar

On average blood sugar, I agree with the point made. Without a continuous monitoring system you can't get a true average unless you're prepared to jab yourself every few (very few) minutes.

However the numbers in the spiel you picked up don't really work in my view. Fasting should be below 100 - anyone consistently delivering a fasting up around 120 has an issue.

By two hours after eating, your figure should be returning to more or less where they were at fasting. As a diabetic with a weak to non existent phase 1 response, the figure will come down more slowly than a non diabetic individual's would.

Testing at one hour, that your spiel seems to suggest is unnecessary is useful and it will show you where you are peaking in terms of spike. Whether your doctor wants it or not, it will give you useful data.

The figures that you seem to have for 'slightly high' are, in my view a virtual guarantee of complications. At two hours evidence suggests that anything over 140 is dangerous. Healthy Blood Sugar Targets

The description you have of the HbA1c test is more than a bit over simplified. Yes, it gives a crude mapping to your average blood sugar over a period of about three months but it can be skewed both up and down by many factors.

Anyone with anaemia will get a low reading.
Have a carbohydrate binge in the final month before the test will throw your numbers up.

I also disagree with the definition of 'non diabetic'. A non-diabetic HbA1c will lie in the range of 4.3% to 5.7% but frankly anyone with an HbA1c above 5% should consider themselves as diabetic. There is no such animal as a pre-diabetic.

First, you need to provide a link to the information. Legalities.

Second, compare your post to this one. You will see lots of differences. This is the one we follow.

My advice is to stop trolling around the internet - this will just confuse you. I recommend that you stick to this forum and Blood Sugar 101 for your information. There IS a lot of misinformation on the internet. There is no misinformation on this forum because the owner and moderators make sure of it. You can't say that is the case for other sites and even other diabetes forums.

You are new to this, but many of us here are not new. We've learned the hard way who to trust and who not to trust. Take advantage of our experiences.

Take your meter and a bunch of test strips. Test before each meal. Eat the meal. Test every 30 minutes after first bite. Write it all down. Learn when you are most likely to spike and how quickly you return to pre-meal levels after spiking. Do that several times with several different foods.

Look for serious, peer-reviewed research into what is 'high', what is 'normal', and where organ, vascular, and nerve damage is likely to happen.

Compare this to your spikes. Decide how high you want your highs to be. Test BG while you adjust your eating and exercising to meet those goals.

Thereafter, test when eating something new and periodically test meals you know to see if anything is changing.

Does anyone else find that when meal is very high fat that the "spike" might be delayed for 2- 4 hours?

Yes, that is often the case.

Totally. AND the high might extend for several hours. Fat slows digestion waaaay down.

The slow digestion of fats is what brings the satiated state, and keeps the hunger pangs at bay. The key is to not eat carbs along with it. That's the recipe for disaster. LCHF has GOT to be greatly reduced carbs along with the increased fats - otherwise you have carbs spiking our blood sugar, and the fats prolonging it.
