Glucose tolerance test

I also had an OGTT, 2 months after discontinuing every medication. I quit exercise for 2 days, and had normal food as always. For the test, I dissolved 75 gm dextrose monohydrate in water and drank it. The blood glucose readings were:

Fasted 91

30 min 225!

1 hr 171

Had to go out. The next was checked in a lab.

2 hr 12 min 91

My peak was very high, but then the insulin kicked in and in about two hours, my blood glucose returned to fasting levels. According to WHO criteria, this is considered non-diabetic.

Cheers!

  • Sorry!A non-diabetic person never spikes above 140.

  • What are your references? WHO criteria for diabetes consideres the 2 hr peak. Please see who.int/diabetes/publicatio...

  • I am talking about a non-diabetic person!

  • And do you have a study that has profiled ̂non-diabeticŝ with a continuous glucose monitoring system to make sure that they never spike above 140?

  • A diabetic person having controlled BS levels can not be treated as a non-diabetic.

  • A diabetic persoǹs blood glucose will not come down to below 140 mg/dl in 2hours after ingesting 75 gm pure glucose.

    Oral Glucose Tolerance Test

    The OGTT can be used to diagnose diabetes, prediabetes, and gestational diabetes. Research has shown that the OGTT is more sensitive than the FPG test, but it is less convenient to administer. When used to test for diabetes or prediabetes, the OGTT measures blood glucose after a person fasts for at least 8 hours and 2 hours after the person drinks a liquid containing 75 grams of glucose dissolved in water.

    If the 2-hour blood glucose level is between 140 and 199 mg/dL, the person has a type of prediabetes called impaired glucose tolerance (IGT). If confirmed by a second test, a 2-hour glucose level of 200 mg/dL or above means a person has diabetes.

  • Yes, have posted many times out here.

    So search.

  • I know the 30 minute peak is unusual, but the widely accepted guidelines for diagnosing diabetes consideres the 2h value.

  • You are OK, don't indulge yourself in deep technicality, better to care and enjoy your life fully, without worries about diabetes, but remember " NEVER BECOME CARELESS"

  • Yes, diabetes came as a blessing in the sense that I will be watching myself always and will be leading a healthy life.

  • Dear 'kapilv'

    Congratulations for your achievement and wish you all the best for future life. Enjoy it and at the same time monitor it. A t2 diabetic will always be happy with this results. Now friend, would you kindly share how you achieved this ? What was the time frame and obviously diet plan. Exactly what diet you had taken during the period, if you kindly share it will be beneficial for me as well as other forum members.

    Thanks in advance and congratulations once again.

    God bless & good luck.

  • congrats. Achieving your desired BS is very tough, but consistency paid. As some of our colleagues have mentioned enjoy life, keep good health, don't worry unnecessarily, but always keep a tab on your BS and check them once in awhile, to be on the safe side.

    keep good health and take care.

    keep reporting once ina while.
