Bizzare blood sugar

Dear friends

I have recently undergone tests to become a kidney donor, been given a lot of tests one of which was the fasted test (12hr fast) and the consultant was baffled with the results my blood sugar on an empty stomach was 5.2 then I had a glucose drink then returned 2 hours 20 mins later as the nurse was late, my blood sugar was 4.6 which is lower than fasted

He wrote to his diabetic doctor but awaiting an appointment to discuss this but not 100% sure what this could be?

I have since bought a machine and tested my own, the results are always the same

Fasted or unfasted in the morning 4.9-5.3 and 2hours after eating 4.6-4.8

I follow a low carbohydrate diet during the week taking in 30-50 grams of carbs

Macros are normally 55-60% fat/ 30-40% protein and 5- 10% carbs, my fats are normally saturated/mono with some poly

I workout 6 days per week sometimes 7 with weights and cardio

My body weight while 16 stone is not fat but very athletic, my waist is small too.

I must say I was worried I was diabetic when he wrote to me however looking at the Nhs website etc it appears I fall well within the normal ranges, however it appears eating I may over produce insulin or suffer from something else?

Not 100% sure to be honest wanted to ask if anyone suffered something similar?

Thanks

Pure lay person speculation on my part, but I might wager they might repeat the test before reaching any conclusions.

Good luck with the kidney donor aspect. It takes some courage to electively give up a perfectly functional organ.
 
I'm a little puzzled by your results as I'm sure many will be on reading them. My only thoughts are that the standard B/G reference levels are in effect Average levels that most people would comply with, being average levels there are some individuals who will be either higher or lower than the average values and you might indeed be one of them. Also it might be that with your regular workouts at the Gym, you have toned up both your muscles and reduce your insulin resistance, hence after eating what insulin you are producing is working to reduce B/G levels more effectively.
It might also be worth looking into the effects of Rebound hypoglycaemia which would explain to some degree why there is the drop below the starting fasting B/G level, maybe even conduct your own OGTT to see if this is a possible reason for the drop in your B/G level.
There is also the possibility which you refer to in your posting that for some reason you pancreas is overproducing insulin as production of insulin is controlled indirectly by specific hormones which might in themselves be over produced.
Test are available to monitor the degree of insulin present in the blood which in the case of one type 2 diabetic that I know who is overweight and suffers insulin resistance was shown to be 15 times the normal insulin levels of a non diabetic.
These are only my thoughts, but I wouldn't like to say what if anything is causing this.
I hope that what I've posted is of some use and helps shed a little light on this problem, which might in the end prove not to be a problem.
Hopefully someone will come back with a further answer - Best Regards
 
I echo @Daibell. You are normal and very healthy.

I suspect that the original tests were done with a standard consumer blood glucose meter? In which case the "variation" between the readings is within the expected variation for those devices, and is not significant.

Hi. All your results are well within the non-diabetic range, so I'm not quite sure what the consultant is querying?

I am guessing the consultant is probably just wondering why I am getting such results and because I am going to be a donor wants to be over cautious due to me having to live my life for many years to come I am only 30


They always go over the top with tests for donation I have had so many tests you wouldn't believe

This is what my thinking was with the insulin resistance, I wanted to see what others side about it.In honesty I am just happy I am not showing signs of diabetes however at the same time hoping that I don't have any issues with my pancreas

I do diet hard with a variety of foods,track my diet well. I eat sugar goods still but keep it to weekends and then I don't go over the top

Thanks for the reply I appreciate it a great deal
 
I was under the impression that before an oral glucose test it is necessary to eat carbs normally for 3 days beforehand or you get skewed results??????

If I'm not mistaken you have said this before. I think it all depends on what the OGGT is for. I have never done this on my five tests. Always fasting. Maybe because I start at 'normal' levels.

If I have said this before it's only because I picked it up elsewhere on the forum. I'm sure others have said it.
 
I found this fascinating article on insulin response:

http://meridianvalleylab.com/wp-content/uploads/2012/08/GITT-Article-Re-type1.pdf

People low carbing had an insulin response similar to type 1 diabetics.

From the article (I did the bolding):

"In the absence of pancreatic gland dysfunction,
such as insulin pattern suggested low
carbohydrate diet preparation and/or management.
Figure 7B: Pattern V- low insulin response: a. all
assay values are within normal fasting range of 0
to 30 microunits; b. in the absence of pancreas
gland dysfunction, low insulin is indicative of low
caloric/carbohydrate diet preparation and/or
management.

In these cases, standard high
carbohydrate diet preparation for two or
more weeks followed by repeat tolerance
examination was necessary to uncover
the true insulin response pattern. Figure
8A illustrates a flat insulin response
pattern which became normal following
high carbohydrate preparation. It was not
possible purely on the basis of the initial
tolerance test to predict whether the
subsequent insulin response would be
normal, borderline or delayed."
