Erratic readings

I gave in to the urge to eat a kit kat last night so my bg went up 12.4 . Today when I woke it was 9. I decided to keep carbs low. 2hrs after breakfast it read 7.7. Late afternoon not much different.

I went to low impact Zumba for first time after work and felt that I achieved something. when I got home I checked my pre meal bg and it read 16.5 :shock: I figured that can't be right so I checked again 7.6, then again 8.8, then again 9.2, then I gave up. ate pâté on soya and linseed toast.

2 hours later I tested again -11.3, then again 12, then again 12.5, then again 13.3

How can I ever trust my test readings if they can differ so much in a matter of a couple of minutes? I'm not rich enough to test 4-5 times every time just so I can work out an average.
 
I think they say that the inaccuracy of BG meters is something like 15 percent. So if you measured 10 mmol, it could be anywhere between 9.2 and 10.8 in reality. This will explain the deviation on most of your results.

The single high figure after workout might be either a blip (not entirely clean fingers, just plain random) or it might be that the exercise pushed your BG up temporarily which is not uncommon.

The rises in blood sugar from your meals are all fairly sensible. I think the recommended rise in blood glucose after a meal are generally thought to be 2-3 mmol.

If you get a result that is clearly off, like your 16.5 which made no sense to you, yeah, I'd measure again. If you get something that is inside your 'sensible range' which for you seems to be 6-10 mmol at the moment, I'd not worry to try and get an entirely accurate figure, but consider it 'close enough' for you to be able to act on it which in the end is the whole idea.

Thanks for that. Last night I felt that my doctor was right and there was little point in testing too often. But then I woke with my sensible head back on.

bg reading was 7.6 before breakfast this morning, so I sensibly ate scrambled egg on a slice of buttered soya and linseed toast. then briskly walked to work (usually take car) 2hrs later my bg was 13. I have been taking metformin 3 times a day for 8 weeks. I'm, feeling envious of those who's reading seem to consistently be around 5. I haven't yet managed to get that low. :(
 
The increase in bg levels after such a relatively low carb meal may suggest that you consider further medication, there are a number of different avenues that can be explored. You say you take metformin three times a day is that one 500mg tablet three times a day? if so another 500mg can be added, most people on a max dose of metformin usually split it between two at breakfast and two with their evening meal.

Gliclazide is often the next step drug or there is Sitagliptin they both work by making the pancreas work a bit harder but work in different ways. You may want to talk to your doctor or DN and explain that you are struggling to get your levels down.

Are you overweight? if you are the best thing you can do to help reduce your bg levels is to loose weight, weight loss will reduce your insulin resistance and you will see a big drop in levels if you are able to lose weight. Obviously not an option if you are of slim or average build.

Do speak to your doctor though and explain that you are doing all you can :thumbup:
 
I called the doctor to make an appointment after having a blood test 6wks after starting medication. Surgery fully booked up for day. I Explained to the receptionist that I would like to know my blood test results. She said the results came back satisfactory. I asked her what that meant, she couldn't answer. I wanted to know whether the test was my hba1c. And i had other questions about medication etc. In the end the receptionist asked if I would like the doctor to call me. I said that would be a good idea.

I then spent the next 2 an a half hours being talked to like a child durning my 2nd session at the Xpert classes. We discussed food, what are carbs, protein, fats, fruit etc and why our body needs them. Out came the healthy eating plate with 1 third designated carbs and 1 third fruit and veg. The other third divided between protein, fats and dairy. We had to place magnetic pictures of various foods in the sections we thought were applicable. :roll: I suggested that maybe protein should swap places with the carbs, and the fats take up more of the fruit part of the fruit and veg section. She looked at me as though i'd suggested eating human body parts and carried on as though I hadn't said anything, We watched a video on the importance of exercise. I learnt nothing.

Afterward, I received a call from the doctor. I asked what satisfactory meant, she said that the result was within the acceptable range. I asked if the test was my hba1c, she said it was. So I said I would like the actual result (like extracting teeth getting information over the phone), 51 she said, which I assume means 5.1. She said that the results indicate that I do not have to test my blood glucose (any excuse not prescribe test strips).

I told her that I now buy my own strips and that my readings were anything but normal, She said that If I adopt a healthy lifestyle, lose weight and exercise, my levels should go down. No **** shirlock. So what are the tablets for? I said that since diagnosis I have adopted a healthier lifestyle, losing weight and exercising regularly. She said that my average readings are all I need and should not be self testing.

She also mentioned in passing that the results show I have a fatty liver, and then went on to say if I need any further advice about diets I should speak to diabetic dietitian. I gave up, thanked her for returning my call and hung up.

I googled fatty liver, now I know I'm not a heavy drinker so that's not the cause. What is looking scarily familiar is Metabolic Syndrome which a fatty liver can be a symptom. along with carrying a lot of weight around middle, high blood pressure (although mine is controlled) and of course diabetes. (whilst googling Metsbolic Syndrome it linked me to an information page on this website).

Now, do I have metabolic syndrome I wonder. Not that it makes any difference, adopt a healthy lifestyle, lose weight and exercise seem to be the recommendations for that as well. However, I did read the following statement on wikipedia

'Restricting the overall dietary carbohydrate intake is more effective in reducing the most common symptoms of metabolic syndrome than the more commonly prescribed reduction in dietary fat intake'

Maybe I should show that to my diabetic dietitian, xpert presenter and doctor.

Just to say thanks to everyone here, i'm not banging my head against a brick wall. If I hadn't found this website I don't know what I would do. No one I speak to, even those that are diabetic, seem to understand my choice to lower my carb intake.
 
When the doctor told me over the phone that my hb1ac reading was within the acceptable range at 51, I aasumed she meant 5.1, but now I'm not so sure.

My readings since being on Metformin 3 times a day 10 weeks ago have never been below 7. First thing in the morning, berfore meals, whenever. After meals (depending on the meal) can range between 7.5 - 13.2.

I'm sure 51 can't mean around 7, Isn't that quite high for someone on medication?

Would the 51 mean 51%, if so does anyone know how it converts?
 
Thanks for that Phoenix. So my avg is 6.8. Not bad considering i'm never below 7 when testing.

Now. I would like to think that my attempts at lowering my carb intake helps to keep my bs down. But then it could be the tablets.

I suppose the only way I could find that out is to start eating high level of carbs again and see how my bs reacts... No I think not.
 
Hi Tootsie, Sounds like you have been getting the run around! I'm lucky that my Dr and DSN have both been supportive of me trying a low carb diet, although the DSN said I should only do it for the short term and then start re-introduce carbs - little does she know ...

From your posts I just thought maybe the burgen bread is making you spike. Both times you talked about food you mentioned burgen toast. If you are having 2 slices, maybe you could cut back to 1. I personally don't eat any bread at all at the mo, becase it makes me spike.
 
Hi Fraddycat. It is possible that it could be the bread, but there are days when I don't have any.

However, I do need to be more disciplined in my eating as well as my testing. When I say disciplined, I need to plan my meals before I shop. At moment, I'm eating invariably the same things because the lack of choice in my fridge. I have various recipe books on my iPad but forget to look at them before shopping. I must also stop snacking on fruit. Although it's small amounts, it's difficult to decide whether the test results are from the meal or the fruit.

Also I know I need to start recording what I have eaten and test results that come from what I've eaten for future reference.

It's all a learning curve and my rebellious head still tries to ambush my attempts to change, but hopefully I'll get there.
