Question: I think my blood sugar is swinging a little too high and then a little too low.

Fasting in the morning = 92-95
1.5 hrs after a HIGH carb breakfast it shoots up to 150+
An hour or so later it's drops to 55-65     

2 hours after a somewhat high carb lunch it could be 140 or it could be 82

My doctor just said "your not diabetic" but I dont think she's qualified

My average is 120 over 5 days of testing 4 to 5 times a day

Do you think I should see an expert?

The only reason I got the tester again was because I tested at 58 using a friends and it was in the middle of the day. A week later I tested 155 in the middle of the day.

Brief Answer:
needs further investigations..

Detailed Answer:
Greetings Sir, Welcome to HCM,

I've gone through your query and understand your concern..

Now after looking at your trend of blood sugar(Pre & Post meal) , I'd say that your Doctor is partly right when she said that your not diabetic..

'Partly' because the trend of rising and fall are almost within Normal range only..

However, your absolutely right that , just on the basis of these values , you can't be declared 'Diabetic'.. it requires further testing on this context..

So I'd suggest you to please go for a proper Lab-based FBS, PPBS-2 Hrs (OGTT) , HbA1C along with a urine routine microscopy which will give a definitive conclusion whether your diabetic or not..

Now the trick for OGTT is to have it after having certain amount of Glucose(75 gm to be precise) , better to have it at lab due to controlled and supervised atmosphere to minimize the errors..

The reason why you've got those fluctuations in your results are most likely due to unmeasured quantity of Carbohydrate(please note that there are simple as well complex carbohydrates), their calorific values are highly variable, also depend on cooking and preparation as well as several add-on and several other factors which can't be controlled at home, so better to get checked in any state of the art Laboratory..

Also, if your having any family history of Diabetes, any past medical illness, any dehydration , any particular use of medications like steroid etc. , binge alcohol intake and a list of several other factors affect your blood sugar in short term as well as long term..

So as you can see, blood sugar readings are a variable parameter (I won't be surprised if after all those tests , you get declared as not having Diabetes, quite a possibility..)..

So just go ahead and get tested to be assured..

My Best wishes

I hope I was able to make my answer simple enough so that your doubt gets clarified..Let me know if you have any more..

Kind Regards

Thanks, I alreadyhad the HbA1C and urine routine microscopy (just waiting for results) so I will look into the other tests and see if I can get those performed. I need to justify the test to get my insurance to cover them so I will see if I can get my doctor to prescribe them. I have two sisters and they are both type2 diabetic.

Thanks

Brief Answer:
you're on the right track..

Detailed Answer:
Welcome Back Sir,

Thanks for following up..

So then half of your work-up is already done , just get the rest done before making the diagnosis..

Yes , your Insurance should cover this as, at your age (61 yrs) with a Positive Family history, it certainly comes under the Preventive Health Check-up, and if they don't then you have quite the ground to ask for it..get a properly written Prescription from your Doctor and that's all..

By the way I should also tell you (between You and Me) that the chances are quite thin in respect to brother sister inheritance of diabetes if none of your parents are diabetic..

Take Care
Kind Regards

Yes, none of my parents were. My sisters are both obese but I'm only a little overweight.

Someone suggested I might have "postprandial hypoglycemia" and that I should eat less carbs at each meal.

Along with the tests you suggested - I will play with my diet and keep monitoring blood sugar.

Brief Answer:
no, please don't play with your diet ..

Detailed Answer:
Welcome Back Sir,

Well that's always good to know , however since you've mentioned the overweight issue, then let me know your body wt as well as height so that I can calculate your BMI to get a precise info about it(even you, yourself can do it , by using those standard BMI calculators available online but if you do, please ensure that you put the right data and the right unit)..

Once again I'm requesting you not to go in to 'Someone's Sayings' as each and every term (eg. Postprandial hypoglycemia in this case) carries clinical significance and they are medically established , so can't be coined just like that..

No , playing with food won't be such a good idea, as even if you're not come out as diabetic, still you'll be needing diet and lifestyle modifications in due course..(you can seek a dietitian for a comprehensive diet chart preparation as per your daily requirement)..So I'd rather disagree with that part..

At first just focus on the diagnosis part, if everything comes out fine then you won't be needing monitoring of blood sugar on daily basis. Once in 6 months will do just fine in that case..


Take Care
Kind Regards
