Hello Community,

A little background. . .I am a 29 year old male. I am not "diabetic" but my father was diabetic. I have been getting my blood glucose reading, as well as my a1c, the last several times that I've had my cholesterol checked. My fasting number have been between 100 and 110. My worst a1c so far has been 5.6. I guess I'm in the "prediabetic" stage.

I'm curious to know - in healthy individuals without diabetes - how high does ones blood sugar spike 1 hour - 2 hours AFTER eating?

What would be the Post Porandial blood glucose threshold that would need to be crossed to suggest that a person has a potential problem?

I'm asking because I just started testing my blood at home and have seen that at times I've spiked as high as 186 and 238 approximately 1 hour after eating. I generally seem to go back down near 100-110 approximately 2-3 hours after eating.

Thank you for your help

People with diabetes when they don't eat it makes it go up , and if we don't watch what you eat it goes up, but when you eat it will go back to normal I hope that helps,

I see you are going to have to do I and countless others have done. Figure out what foods makes you spike and learn to avoid them. The First Rule: At first it will be at times very frustrating. Second Rule: Do not expect over night results especially when using herbs, spices. Third Rule: Learn all you can. Do not be afraid to ask questions and talk to people. Fourth Rule: When all else fails see first rule.

Well, I'm right there with you. I can't remember having a 120 or lower an hour or 2 after eating and usually. It's between 150 and 250, depending on what I eat. My morning fbg was 124 today. I eat little during the day and try not to have much for dinner. I take 2000 mgs of Metformin thruout the day plus several non diabetic meds. I get tired and sleepy very easily so take a part of Nuvigill which combats fatigue. I try going without but…I don't know if my BG levels cause that or not. My picture is me yelling at me courtesy of grandson tweeting it. Right now I'm eating cantaloupe so I'll test in awhile.

Hi, I'm not a depth expert of your issue, but I can certainly advise you to take help from this ebook. I have read from it myself not completely though, and now I know a little on how I can actually control my mother's sugar level and what things she should avoid eating and doing; in short, the cause and eliminating it. Here's the link to that ebook:

Do let me know if this ebook was helpful to you.

The A16 is great! what concerns me is this 186 - 238 1 hour after eating, that is not good. I am perplexed, because 2 hours after eating the 100-110 is good. we want to be under 120 2 hours after eating. I feel that anywhere near 200 just 1 hour after eating is too much. most diabetics on meds. would have that, and that is frequent for a lot of them. I would suggest you have the Fasting Blood Glucose Tolerance Test as soon as possible. you did not mention if you had this test. some doctors are going by the A1C now only, which in my humble opinion is just plain wrong!! "some" can slip through the cracks that way. If my doc has done only A1Cs on me, she would not have pronounced me diabetic, however, I failed the FGTT big time!! I do have diabetes, despite the fact that all of my A1Cs are good. I no longer get A1Cs regularly, and I need to get back to those about twice a year, like I used to. I am interested to hear what your results will be. Good luck.

According to a study of blood glucose levels of non-diabetic subjects done in 2006 -
"After a high carb meal, normal people's blood sugar rises to about 125 mg/dl for a brief period, with the peak blood sugar being measured at 45 minutes after eating and then drops back under 100 mg/dl."
"What would be the Post Porandial blood glucose threshold that would need to be crossed to suggest that a person has a potential problem?"
I've been diabetic for over 7 years and have never had readings over 200 … so in my totally non-medical opinion … the threshold has been crossed.

wow! that is really good haoleboy! That is me also. I have never seen a reading at 200 or above and my anniversary of diagnosis, will be 6 years in early Nov. I am quite shocked by this. The first year after diagnosis, I checked when I woke up, then 2 hours after most meals or at least 2 hours after most meals. then I gradually began to check less and less, but still once or twice a day. in the beginning, I checked before and after exercise as well. The last two years or so, just once a day. I am still waiting and looking for those numbers to go up, which they do, but temporarily, and the A1Cs are still pretty good. I no longer get my A1C checked as often as I should, so I need to go back to that. no high blood pressure, no high cholesterol though at first I had to work on all the cholesterol numbers. I do have occasional spikes, but those are when I fall off the wagon for a bit. It is very rare that I have unexplained spikes.

Howdy BMelikia
A BG (blood glucose) of 180 mg/dl, 2 hrs post prandial is not unheard of for PWDs (persons with diabetes) The 238 mg/dl is a real cause for concern. I am not a Dr (nor do I play one on TV) but my guess would be that if you got checked out by a Dr, they'd probably say that you were "pre diabetic".

Your pancreas seems to be not able to keep up with the glucose burden under which you place it when a large carb - laden meal is consumed. It does recover after a time,

Perhaps if you give your pancreas a rest by not eating high carb meals, you may be able to avoid full blown diabetes. Right now would be the time to alter your lifestyle and go more low carb and high protein with your eating plan, avoiding starchy veggies and higher carb fruits,

God's best to you

A tip to make you answer a bit shorter
Instead of saying
"PWDs (persons with diabetes)"
just use

thanks for your suggestion Iron
I don't like to use the word diabetic to refer to us, and I have learned that if I don't define the initials I get questions later. So I do that and use the initials later on if I need. Thanks for being so concerned for my number of keystrokes.

Thank you for the reply James

If I give my pancreas a rest by going on more of a low carb / high protein diet - does one's pancreas ever "recover"? Or sadly - is that now how it works?

Thanks again

I seem to have noted my pancreas being able to handle higher carb foods after I had given it about 1 year's rest. I am on a high protein, low carb meal plan (3 + yrs now) and when I indulge in an occasional treat (ice cream) I won't have as high a spike as I would have years earlier when I was on NPH insulin. So at least in my case I believe that mine has at least partially recovered. I still have my T2, but my diabetes seems to be better than it had been even when injecting insulin. Of course everyone has different responses to the same input.
