Fluctuating blood glucose and post-meal readings.

Hi all

Long story short - been having symptoms for some time, ie thirsty, hungry, running to loo a lot, especially at night, feeling shaky before meals or if miss meals, feel horrible and hot, sweaty, tired and ill after sweet/carby food.

At Easter, I stupidly decided to indulge my sweet tooth and tuck into a delicious Easter egg, even though I knew I'd probably pay the price. A mere matter of a few hours later, I was literally passed out on the sofa for half the day. When I finally came to, I was in a cold sweat and had gone pale and felt horrific. Partner made me a cuppa then I managed to drink something sweet and haul myself to the bathroom (feeling sick) but wasn't sick, then I tested my blood (have a few meters lying around after similar episodes happened not so long ago). The reading was 3.6 - have no idea what it was before I came to. The thing is, my partner says I am passing out half the time on the sofa and he cannot wake me up and often I literally fall asleep mid-text or holding a mag/book or phone etc. When I do come round, I have no memory of falling asleep or of him shaking me or shouting at me to wake up, which he says he does regularly. He has been on the brink of calling an ambulance several times but I have come round eventually.

Anyway, after Easter episode, I went to the doctor, new GP, who questioned why I would even be using a meter etc. I said because I drive a lot for my job and these episodes of low blood sugar were concerning me, as were the post meal readings, which have been anything up to 9.5 even 2 or 3 or more hours after a meal. Fasting levels in the mornings have been in the 5.6-6.6 range and I do tend to hover around 8 after most breakfast/lunches/dinners and feel extremely sleepy 2 hours after a meal, to the point where I'm struggling to keep my eyes open.

This doctor said readings after meals don't count and I should only worry if they are above 11 and that the main readings that matter are fasting ones. Last year I had a fasting test which was 5.4 after a 13 hour fast (although have seen higher readings at home on occasional fasting tests I've done with BG meter) and a HbA1C was done on blood screen, which was 5.1 but I was never given those results until today (tests were a year ago due to same symptoms which are worsening slowly over time). The GP also said that levels of 4 or below are nothing to worry about, only levels below 3, but I am persistently having fairly severe hypoglycemic symptoms at even 4.4 and certainly much worse at 3.8, 3.7 etc. In context, when I came to after last 3.7 reading, I was that confused I could hardly work out how to take a reading and I was confused over where our bathroom was a few mins previously! If this happened while I was driving, I don't even want to think what might happen.

I felt that the GP dismissed my concerns, especially when I said I now also have blurred vision, like lines across my vision, which started a few months ago and comes and goes. In fact, she spent most of the consultation downplaying the numbers and simply wouldn't comment on whether it is safe to be driving currently or not.

So, apparently post meal readings are not significant, even at 9.5 and readings below 4 are not significant, only below 3. If this is correct, why do I feel horrendous when I get post meal readings above 7/8 and I feel horrendous when I drop to 4.4 ish and below? Is it true then that even if I am hovering around 8/9 mmol/l for hours after meals that no damage is occurring? Or if my levels are swinging between 4 (or less) and 9ish all during the day, that no damage is occurring? What is blood sugar supposed to be doing during the day, during normal activity i.e. seated computer use and normal meals ie balanced carbs/protein/fats?

I must admit I am more inclined to listen to my body despite the doctor's dismissiveness and these hypo episodes along with post meal sweating/boiling hot/sick feeling, coupled with my worsening fatigue etc is really making me feel quite ill for large chunks of time.

Any advice welcome, especially re swinging blood glucose readings, the range of numbers i.e. under 4 and above 9 and the implications of fluctating between these.
 
If I were you, I would make an appointment with a differnet gp for a second opinion.
Ask for a glucose tolerance test when I was diagnosed I had a normal HBA1C, however I failed the glucose tolerance test.
 
read the advice for the newly diagnosed in the greetings section it may be useful even though you have not been diagnosed diabetic.
 
Hi there!

I'd fully agree with what Louiseb has advised. I had normal fasting levels but BGs into the teens after eating. It was the Glucose Tolerance Test (GTT) that diagnosed me. They take a fasting blood test, give you a measured amount of glucose to drink, let you sit down for two hours and then take another blood test. This shows whether your body is metabolising sugar properly, as a non-diabetic should be almost back to their fasting level after the two hours. I think anything over 11 is classified diabetic in this test. 8 to 11 is impaired glucose tolerance (pre-diabetes). Fasting tests and HbA1cs don't tell the full story because they miss the spikes - the GTT measures that spike!

Hi and thank you for the replies, much appreciated.

I did ask the GP today for a Fasting Glucose Tolerance Test but she refused and said she would only repeat the fasting test. It was almost as if she did not want to acknowledge even the possibility of diabetes!

Hi CarbMonster and welcome to the forum :) Here is the information that Louiseb mentioned. This basic information is prepared for new members by the Forum Monitors and you will probably find things that will help you in here, particularly on diet. Even though you have not been diagnosed, whether you will be or not, this advice will be useful to you.

Here is the advice that Ken and I, as Forum Monitors, usually give to newly diagnosed Diabetics. We hope that these few ideas gained through experience help you to gain control and give you some understanding of Diabetes. This forum doesn't always follow the recommended dietary advice, you have to work out what works for you as we are all different.

It's not just 'sugars' you need to avoid, diabetes is an inability to process glucose properly. Carbohydrate converts, in the body, to glucose. So it makes sense to reduce the amount of carbohydrate that you eat which includes sugars.

For more information on CARBOHYDRATE see here:

viewtopic.php?f=3&t=20306

This is NOT a low carb diet suggestion, just a reduction in your intake of carbohydrate. You have to decide yourself how much of a reduction will keep your blood glucose levels in control.

The main carbs to avoid OR reduce are the complex or starchy carbohydrates such as bread, potatoes, pasta, rice, starchy root veg and also any flour based products. The starchy carbs all convert 100% to glucose in the body and raise the blood sugar levels significantly.

If you are on Insulin you may find that reducing the carb intake also means that you can reduce your dose of insulin. This can help you to keep weight gain down as Insulin tends to make you put on weight and eventually cause insulin resistance. This should be done slowly so as not to cause hypos.

The way to find out how different foods affect you is to do regular daily testing and keep a food diary for a couple of weeks. If you test just before eating, then two hours after eating, you will see the effect of certain foods on your blood glucose levels. Some foods, which are slow acting carbohydrates, are absorbed more slowly so you may need to test three or even four hours later to see the effect that these have on your blood glucose levels.

Buy yourself a carb counter book (you can get these on-line) and you will be able to work out how much carbs you are eating, when you test, the reading two hours after should be roughly the same as the before eating reading, if it is then that meal was fine, if it isn’t then you need to check what you have eaten and think about reducing the portion size of carbs.

When you are buying products check the total carbohydrate content, this includes the sugar content. Do not just go by the amount of sugar on the packaging as this is misleading to a diabetic.


As for a tester, try asking the nurse/doctor and explain that you want to be proactive in managing your own diabetes and therefore need to test so that you can see just how foods affect your blood sugar levels. Hopefully this will work ! Sometimes they are not keen to give Type 2’s the strips on prescription, (in the UK) but you can but try!!

For TIPS FOR STRIPS see here:

viewtopic.php?f=20&t=19002#p173253

If you are an Insulin user in theory you should have no problem getting test strips.

The latest 2011 NICE guidelines for Bg levels are as follows:
Fasting (waking and before meals).......between 4 - 7 mmol/l...(Type 1 & 2)
2 hrs after meals........................no more than 8.5 mmol/l.....( Type 2)

2hrs after meals......................... no more than 9 mmol/l ......(Type 1)

If you are able to keep the post meal numbers lower, so much the better.

It also helps if you can do at least 30 minutes moderate exercise a day, it can be split into 10 min sessions to start with. It doesn't have to be strenuous.

The above is just general advice and it is recommended that you discuss with your HCP before making any changes. You can also ask questions on the forum on anything that is not clear.

Finally a few QUESTIONS TO ASK AT DIABETES CLINIC.
