You remember, an oral glucose tolerance test (OGTT) measures how our blood sugar levels respond to 75 grams of glucose,” says Dr. Slinkin. I don’t recommend this test because A) it’s unrealistic (no one ever drinks 75 grams of pure glucose), and B) it can cause terrible side effects in people with poor glucose control.

However, according to Denis, there is another more realistic and convenient way to achieve such a measurement, namely, to simply use a glucometer to test the sugar in your blood one and two hours after eating. This is called a post-prandial (after meal) blood sugar test. As we look through this section, the numbers I use refer to both OGTT and post-prandial testing.

As you can see from the table at the beginning of the article, the FBS believes that OGTT 140 to 199 hours after a call is prediabetic and levels above 200 are diabetic. But again, continuous glucose monitoring studies suggest that ADA levels are too high. Most people’s blood sugar levels fall below 120 mg/dL two hours after a meal, and many healthy people’s blood sugar levels fall below 100 mg/dL or return to their original levels.

Continued monitoring of glucose levels showed that sensory glucose concentrations were in the 71-120 mg/dL range for 91% of the day. Sensor values were less than or equal to 60 or 140 mg/dL only for 0.2% and 0.4% of the day, respectively. On the other hand, some studies show that even healthy people without known blood sugar problems may experience bursts above 140 mg/dL after eating for one hour. As I said at the beginning of this article, context is everything and all blood sugar FBS markers must be interpreted together.
If after eating the blood sugar does rise above 140 mg/dL and remains there for a significant period of time, the consequences will be severe. Prolonged exposure to blood sugar above 140 mg/dL results in irreversible loss of beta cells (beta cells produce insulin) and nerve damage. Diabetic retinopathy is an extremely common (and serious) diabetic complication. Cancer levels rise as blood sugar rises above 160 mg/dL after meals. This study has shown that the risk of stroke increases by 25% each time blood sugar levels rise above 18 mg/dL after meals. Finally, OGTT readings for 1 hour above 155 mg/dL strongly correlate with increased risk of CVD.

What does all this mean?¬† Let’s take another look at what ADA considers “normal” blood sugar levels:
Marker Normal Pre-diabetes.
 Lost blood glucose (mg/dL) <99 100-125 >126.
OGGT / after meals (mg/dL in 2 hours) <140 140-199 >200
Hemoglobin A1c (%) <6 6-6.4 >6.4
But as we have seen in this article, these levels are highly contextual and depend on whether all the markers are elevated or only some of them.

If you’re interested in health and longevity – instead of just slowing down the onset of serious illness for a few years – you might want to consider shooting at these targets. But remember to interpret the numbers together, and also remember that blood sugar levels vary greatly. If you wake up one morning and have blood sugar FBS at post 95, but your A1c numbers are still normal even after a meal, this is usually no cause for concern. Similarly, if you see an hour’s spike after a meal of 145 mg/dL, but all other numbers are still normal, it’s also usually not a cause for concern.
