Home OGGT results

[CherryAA]

@bulkbiker bravely did one of these . I ordered the stuff too.

On Thursday of this week I went out for a meal and succumbed to a large portion of mashed potatoes with butter plus some bread and butter pudding.

On Friday of this week I went out for a meal and succumbed to another one, plus some Eton Mess.

I've been doing some exercise so the damage wasn't that bad in terms of weight and my average blood sugars still stayed under 6.
On Saturday I realised that I had actually managed through my " cheating" to eat carbs of D140g, and D2 208g

So in for a penny .... on Saturday I deliberately ate enough to do the Rapilose OGTT test under the specified conditions of minimum of 150g of carbs for three days first so I went for it and had a cheese sandwich on a bap, my first bap since diagnosis ! total D3 205g

@bulkbiker - you may be interested in the results in the graph attached . Basically my figures almost exactly tracked yours . I have a freestyle monitor and the codefree so I used both. I know the freestyle tends to record lower , especially at the low end, and the code free generally records a bit high compared to my hba1C tests.

My starting fasting glucose at the start is a bit elevated as I expected it would be because of the carbs, but I am now back 4-5 range and have stayed there since.

So at the two hour mark my OGTT would NOT indicate diabetes anymore, though clearly I like you get elevated responses initially.

Other side effects of three days on relatively high carbs :

horrible cramp one night
new bout of snoring which doesn't generally happen anymore
much bigger swings in blood sugars (though still under 7.8 other than this test)
flatulence, discomfort
increasing fasting glucose levels
hunger pang when the OGTT crossed 5.5

Weight - Ive stayed in the 87-89 kg range I've had for months.

Remarkably - I am STILL in ketosis - despite the extra carbs and the rapilose - so it seems I really am " fat adapted"

I found it HARD to find enough things I actually wanted to eat to get to the carbs. including being in an Indian restaurant and STILL preferring the sauce without the rice !

Overall take home - I have no desire to go back to eating the carbs.

I will go back to eating circa 30-40g carbs per day and redo the OGTT in a couple of weeks to see if the lack of carbs makes the results a lot worse .

In the meantime, it now appears that if I turned up at a doctors surgery who didn't know I'm diabetic all of my figures from Hba1C , fasting insulin, OGTT and fasting glucose would all pretty much suggest I am no longer diabetic based on a year long adherence to LCHF 60% fat,( inc 22% saturated fat) 20% carbs 20% protein, plus some more exercise resulting in a 27 kg weight loss . I still have 20 kg to lose.


I know I am diabetic because of the interim responses to OGTT before 2 hours - but very encouraging never the less.!

@CherryAA Am I missing something, or just being stupid, but what is the scale on the x axis? I know this is Time since taking the glucose, but how long is each unit?

@CherryAA well done, all seems well as far as I can see. The bottom axis - are those the 15 minute timings?

You didn't have the second rise on the Libre - so most likely the Codefree was a bit off for that one, or maybe a bit off when you dipped sharply whereas the Libre dropped more gently.

I have planned to do mine tomorrow morning. I chose a Monday because we have a roast dinner on Sundays and I have a lot more carbs than normal. I will add extra gravy and peas. I also had a 13g carbs bag of crisps with my lunch and a bowl of strawberries. Neither of which I would normally have had. It won't take my carb total anywhere near the recommended, and only for one day. I was genuinely at a loss as to what to eat!

@CherryAA
Looks like brilliant results for you too.. interesting that you did carbs and I didn't and we still got such close results. We need more guinea pigs! Look forward to seeing @Bluetit1802 results soon as well. Any more keto warriors fancy doing one without carbing up first I wonder?

Mine may be awful, in which case I will hide away in a cupboard. I can't tell you how nervous I am. No idea why - its only 75g of carbs when all said and done! It would be great to see more people having a go.

Following all of you with interest. Am contemplating having a go, but think I should probably wait until I've had this under control for a bit longer as it's less than a year since diagnosis. Let's see what my HbA1c result is when I get it on Friday.

I am going to do it again in a few weeks time once I'm back into my LCHF swing = it just seemed too good an opportunity to miss to complete it under normal " carb loaded " conditions - so next time round I will be able to see how dramatic the lack of carbs is for me on the way my insulin responses work.

I feel for you. This morning before I actually drank the stuff I went on line to look up - can the OGTT be dangerous .... couldn't find anywhere that warned me against it (unless I'm under 45kg apparently ) - which is not on the cards anytime soon -. even then it just said it might give a false positive.

After I drank it I could feel myself thinking " IS THERE AN ANTIDOTE " lol . ridiculous really when you consider just how often one was eating 75g of carbs before and not even noticing.

On the way up, it feels really strange as you have no idea where it will stop . I was SO pleased to see how closely I seemed to be tracking @bulbiker especially given my hba1C is higher than his, and this is only one year since diagnosis for me.

I wanted to do one with a " normal" diet - because that then is a comparator for other published data. I will consider the experiment complete when I've done one on LCHF so I know what LCHF does for me personally in terms of changing my ability to produce insulin as necessary for glucose.

Going forward it would be my goal to do an OGTT annually after my annual blood check which will from here on in also include the fasting insulin test.

Either way its been an itneresting few days on the find out about myself front - if that helps anyone else then great
good luck to all ..

Yes it is really interesting. I am very interested to see what others find to. Way too early for me - I have not even had a HBA1C in normal range yet and my BG fluctuates from FBG of 5 to 7 during the day when closely controlled with 20g carbs max.
Good luck @Bluetit1802 - most interested to see your results to.

I am watching all of this like a hawk.

 

[Lamont D]

It is really interesting!
Having had the extended fasting OGTT a few times and seen my graph differ from when I had high insulin, high glucose, high insulin resistance and then from low insulin, normal glucose levels and good insulin resistance. Hba1c levels can alter the start of the test as does meds.
Having carbs before is something that I have not done with my tests because it would be risky to start high before the glucose was drank.
My last test was indicative of how my body is now use to eating little carbs and the readings showing my initial insulin response to be weak, but my meds which alter and inhibit the glucose spike to just above 8mmols. Which was at least 5mmols lower than without the meds. The second insulin response kicked in and still gave me a hypo.
The awareness of my blood levels going above then below normal, triggered symptoms, that I didn't need or want. Because of the heightened awareness, my symptoms were awful. And it took a couple of days to recover from the hypo.

Even the time that it takes for my hypos to come about is different depending on what I have eaten. I have mentioned before that potatoes are my worst carbs. The spike is quicker, higher and the onset of low levels is just over three hours. Whereas a lower carb food with natural meat and fats slows it down and lowers the time and how high the spike occurs. The hypo happens up to the fifth hour, but more than likely between three and a half to four hours.

Of course, most of you are only interested in the two hour reading.
Mine does follow a different pattern of my graph but not so that would have doctors wondering what was different that type two.
I still have experienced and experimented with all my food and it is typically type two readings at two hours. It does question how alike we are in that experience and explaining is quite difficult as to why we do hypo when you see the graphs.
It is only when you realise that my hba1c is normal, and my pancreas creates too much insulin, when it is triggered into response to carbs. The conclusion is a hypo.

Awaiting more results.

Fantastic result! One of these days I'll build the courage to give it a go........

 

[JohnEGreen]

@CherryAA Very interesting can I be so bold as to ask where you obtained the solution used please.

 

[CherryAA]

http://www.gpsupplies.com/catalogsearch/result/?___SID=U&q=rapilose

I bought a pack of 12 tests - though at presen

t they seem to be selling 1 or 24. Not sure if @bulkbiker used somewhere different.

Well if you did, I would make a bet that your results will be much better than mine

I don't think it is necessary for anyone to do an OGTT. -after all, we all already know we have whacky insulin responses.

I did also keep the data for 4 hours, just that there are no comparatives to show it against - for those interested its stayed rock solid between 4.5 and 5.5 since regardless of food )

I personally have always been interested in numbers and trends - ( I have been known in the past for counting the incidence of different letters of the alphabet on shampoo bottles whilst in the bath ! ).

that particular obsessive counting was of no use to man nor beast - at least this one can be used to help dispel the mystique about what we are doing and why. As such I hope my postings recently have been interesting to follow. No-one should feel the slightest bit concerned if they don't feel ready to follow suit - in the end just like the NHS itself states - it hardly matters precisely what the diagnosis is, if the action minute remains the same .

It clearly does - eat real foods, limit the carbs - especially the junk food and get as active as you personally can - these things will work for T2 diabetics with or without compulsively testing to prove it . Please don't forget that I've been compulsively recording what I ate for nigh on 20 years - this is the first time I have found that information to be of any practical benefit to me - so its not surprising that I might want to milk it !

Following all of you with interest. Am contemplating having a go, but think I should probably wait until I've had this under control for a bit longer as it's less than a year since diagnosis. Let's see what my HbA1c result is when I get it on Friday.

I have no idea if this is linked - but if you look at our signature you will find that both @bulkbiker and I have almost the same levels of both HDL and Trigs in our bloods on our recent tests.

In my first few months, despite improvements elsewhere. My HDL stayed stubbornly low for the first 6 months and it took about 12 months to get to a healthy level.

If you look at this chart
http://www.diabetes.co.uk/forum/threads/you-can-measure-your-own-insulin-resistance.126095/

You will see that you are at about the same stage I was after 6 months in terms of Trigs and HDL . It will be interesting to see if your new results follow down a similar path.

Its a pity more people don't post their fasting blood glucose, and cholesterol make up on the same day each time they get their Hba1C results then we could see if there is a pattern to this !

So interesting. Thanks for posting. I am only 10 weeks from dx, but plan to monitor my own health as much as I can. Good to see it can be done.
