Health ~ Hypoglycemia & Diabetes ~ Glucose tolerance test

Tests aren't everything; if the test is negative you can still get hypoglycemia from not eating enough nutrition. Even the healthiest person can benefit from banning sugar, grains, soy and chemicals. Green is the color of life~ Try it and let your body do the talking, he's the real expect. Tests can still reveal the truth about how well you take care of yourself... or not.

Feel free to only look at my graphics. I based the colored limits on wikipedia:

Interpretation of OGTT results:

Fasting plasma glucose (measured before the OGTT begins) should be below 6.1 mmol/L (110 mg/dL). Fasting levels between 6.1 and 7.0 mmol/L (110 and 125 mg/dL) are borderline ("impaired fasting glycaemia"), and fasting levels repeatedly at or above 7.0 mmol/L (126 mg/dL) are diagnostic of diabetes.

A 2 hour OGTT glucose level below 7.8 mmol/L (140 mg/dL) is normal, whereas higher glucose levels indicate hyperglycemia. Blood plasma glucose between 7.8 mmol/L (140 mg/dL) and 11.1 mmol/L (200 mg/dL) indicate "impaired glucose tolerance", and levels above 11.1 mmol/L (200 mg/dL) at 2 hours confirms a diagnosis of diabetes.

1999 WHO Diabetes criteria - Interpretation of Oral Glucose Tolerance Test:

Glucose levels Normal Impaired fasting glycaemia (IFG) Impaired glucose tolerance (IGT) Diabetes Mellitus (DM)
Venous Plasma Fasting 2hrs Fasting 2hrs Fasting 2hrs Fasting 2hrs
(mg/dl) <110 <140 >110
<140 <126 >140 >126 >200
(mmol/l) <6.1 <7.8 >6.1
<7.8 <7.0 >7.8 >7.0 >11.1

Interpretation of 10 results of typical glucose tolerance tests

Interpretation of 10 results of typical glucose tolerance tests

Introduction (From rajeun)

"The glucose tolerance test (GTT) consists of drinking 100 grams of glucose solution and measuring the blood glucose values every hour to get a curve. The values obtained tell a lot about the body's sugar metabolism. The following 10 tables of results are typical and are interpreted briefly."

"A 2 hour GTT is used to diagnose diabetes, but a 6 hour test might also diagnose diabetes plus hypoglycemia, because symptoms of hypoglycemia occur after the 5th hour."

"25% of the normal population will also show a blood glucose content of less than 50 mg/dl (2.8 mmol/l) but do not show any other symptoms of hypoglycemia. Therefore, to diagnose a person as hypoglycemic, not only the blood glucose values are important but also the person must experience the symptoms of hypoglycemia in the course of the test."

"I do not recommend that you should take a glucose tolerance test, unless you must to diagnose diabetes. You can get a very good idea of your response to glucose by testing yourself with a home glucose meter. Eat exactly 300 grams of spaghetti, rice, baked potato, or 150 grams of white bread. This is equivalent to ABOUT 75 grams of sugar, which is enough to give you a graph. Test yourself before eating, then 30 minutes, 60 minutes, 90 minutes, and 120 minutes after eating."

"If your glucose is above 130 after 120 minutes (graphs 2, 3, or 4), it would be worth it for you to see a diabetes specialist, because you are probably diabetic or "pre-diabetic" (which is already "diabetic" for me). Repeat the test with exactly 400 grams of spaghetti, baked potato, or rice, or 200 grams of white bread, and take your results to a doctor.
Severe symptoms, including psychotic or neurotic behaviour, might occur during the test. For this reason, a GTT should be carried out in a hospital, or in a doctor's office. Persons who take cortico-steroids, birth control pills, diuretics, salicates (aspirin) or fenytoine (anti-epileptic) are strongly discouraged to try this at home. I feel a hand held glucometer is accurate enough to give a correct diagnosis of diabetes or hypoglycemia, but a hand held glucometer is not considered to be quite as accurate as laboratory tests on whole blood samples."

Instructions (From rajeun)

"At least three days before the test a high carbohydrate diet has to be followed (230-300 grams per day). All medication and nutritional supplements should be suspended a few days before the test, because they might influence blood glucose metabolism. No meals should be eaten after 8:00 PM on the day before the test. During the test, no eating or smoking is permitted. The diabetes test lasts for 3 hours. If diabetes is found, it might be wise to extend the test to 6 hours to see if hypoglycemia occurs after the 5th hour."

"The minimum and maximum range in the curves considered normal (below) are an average. The patient's symptoms are just as important as the actual GTT curve."

Typical glucose tolerance test curves (From rajeun)

100 grams of glucose dissolved in water is taken at the beginning of the test. All of the following tests lasted 6 hours, with blood samples being taken at the beginning, 30 min., 60 min, 120 min, 180, 240, 300, and 360 minutes (0, .5, 1, 2, 3, 4, 5, 6 hrs.)
Glucose in the urine might be an indication of diabetes. The average blood glucose level at which glucose is found in urine samples is about 170 or 180 mg/dl.

The curves shown below are used to diagnose several blood sugar metabolism disorders. Actual curves may vary from person to person and in the same person from month to month. If the measured values lie within the ranges of the following 'normal curve,' and if no typical symptoms are present, then it is concluded that the person has "good enough glucose tolerance".

(Note: To convert the blood glucose level values in mg/dl to mmol/l, divide by 18.)

For the sake of simplicity, the following graph shows only:
Normal (Min / Max), Mild Diabetes, Severe Diabetes, and Diabetes with Hypoglycemia. Other typical results are shown only in tables 5 through 10.

bGmax [mmol/l] 6.7 7.5 8.9 7.2 6.2 5.6 6.2 5.8

Normal curve

Normal Minimum curve

A "Normal-Min" curve means your pancreas is still in very good shape. Insulin release is strong and sufficient to keep glucose from rising. Keep your pancreas healthy by not stimulating much release of insulin, ie, eat low carbohydrate meals.

Pathologic conditions causing flat or depressed glucose tolerance results:

Rapid uptake of glucose by peripheral tissue results in fasting hypoglycemia. Intestinal malabsorption results in a minimal increase in serum glucose. Hypothyroidism causes a reduced rate of intestinal absorption of glucose. Low renal Tm for glucose reabsorption results in depressed glucose concentrations.

Normal Maximum curve

The "Normal-Max" response means you are already well started on the road to diabetes. This is "normal" but it is not good. You are aging faster than the minimum possible. Your
pancreas is still releasing enough insulin, but maybe 10% to 30% of your beta cells are not functioning. The stream of insulin is not as much as it was before which is the reason why glucose is rising. You should care for the remaining beta cells by not stimulating release of insulin. To prevent the advance to diabetes, pretend that you are already a diabetic, and start to take care of yourself as if you are a diabetic.... Eat like a diabetic... Cut down drastically on carbohydrates. You might even THINK of injecting insulin to take the burden off of your pancreas.

2. Curve with mild diabetes (Source: Hypoglycemia, Dr. P. Airola)

Time [hours] 0 0.5 1 2 3 4 5 6
bG [mg/dl] 115 145 180 160 120 130 130 130
bG [mmol/l] 6.4 8.0 10.0 8.9 6.7 7.2 7.2 7.2

Curve with mild diabetes

Your pancreas is already partly shut down... perhaps 40% to 60% of your beta cells are
burned out, and the stream of insulin is not enough to lower glucose quickly. Your pancreas is working overtime to bring down glucose. For this reason you are burning beta cells at a faster rate than ever before. The low quality of the insulin is not as good as before, and the long time that insulin is present to bring down your glucose causes you to become resistant to insulin.

3. Curve with severe diabetes (Source: Hypoglycemia, Dr. P. Airola)

Time [hours] 0 0.5 1 2 3 4 5 6
bG [mg/dl] 200 235 265 280 300 295 280 270
bG [mmol/l] 11.1 13.0 14.7 15.5 16.6 16.4 15.5 15.0

Curve with severe diabetes

(That much sugar has to come from somewhere... stabbing yourself with a syringe to keep over eating junk... it's a possible cause and a choice, but no medicine will make that a healthy one. You can heal diabetes type 2 in a week with nutrition... but probably not type 1, not if the cause is a birth anomaly or damaged organs... But it's always possible to heal with the right materials. They claimed that cardiac problems and cancer aren't reversible but they are with high doses of vitamin C.)

4. Continuous low values (Source: Orthomoleculair, 3, 1988, G.E. Schuitemaker, in Dutch)

Time [hours] 0 0.5 1 2 3 4 5 6

bG [mmol/l] 3.3 4.4 5.6 3.3 3.3 3.3 3.3 3.1

Continuous low values

The curve stays under normal levels during the entire test. A rare tumor, called insulinomia, may be the cause. In hospitals, a 3-hour GTT is used in diagnosis.

5. Pre-hypoglycemia (Source: Hypoglycemia, P. Airola)

Time [hours] 0 0.5 1 2 3 4 5 6
bG [mg/dl] 90 115 140 100 85 80 70 75
bG [mmol/l] 5.0 6.4 7.8 5.6 4.7 4.4 3.9 4.2


The curve is typical for a prestage of hypoglycemia. However, a range of mild symptoms may be present at this stage. A 3-hour GTT would not have been long enough to diagnose this type of hypoglycemia.

(But I couldn't find a place that would bother doing it longer, so if you're told that you're okay and crazy; try an elimination test at home. Ban sugary refined stuff and grains, including corn. That should eliminate toxins at the same time since they're often loaded like a gun to give you the illusion that they're edible. Get rid of soy too. And the real name of canola is rape seed, it's a toxic weed! It's cheap and good for their profits, not for you!!!)

6. Mild hypoglycemia (Source: Hypoglycemia, P. Airola)

Time [hours] 0 0.5 1 2 3 4 5 6
bG [mg/dl] 80 120 80 60 80 75 80 80
bG [mmol/l] 4.4 6.7 4.4 3.3 4.4 4.2 4.4 4.4

Mild hypoglycemia

This curve represents a mild form of hypoglycemia. Within the hour, the bG level drops to normal value. During the second hour, the value is far too low, this is typical in case of reactive hypoglycemia. Consequently, the curve rises until the normal value are reached. Because the bG level drops 40 mg% (mg/dl) within half an hour, severe symptoms may occur.

(It's not necessarily how low you get, but how fast you crash.)

7. Severe hypoglycemia I (Source: Hypoglycemia, P. Airola)

Time [hours] 0 0.5 1 2 3 4 5 6
bG [mg/dl] 95 110 120 105 100 60 40 60
bG [mmol/l] 5.3 6.2 6.7 5.8 5.6 3.3 2.2 3.3

Severe hypoglycemia I

During the first 3 hours, the curve is fully normal. However, this curve depicts a form of hypoglycemia that often occurs and causes severe symptoms. The fact that the curve drops more than 20 mg% (mg/dl) below normal value indicates already that severe symptoms might well possible be present.

Back to list ^

8. Severe hypoglycemia II (Source: Hypoglycemia, the disease your doctor won't treat; Saunders, Ross)

Time [hours] 0 0.5 1 2 3 4 5 6
bG [mg/dl] 100 170 110 130 170 125 100 100
bG [mmol/l] 5.6 9.4 6.2 7.2 9.4 6.9 5.6 5.6

Severe hypoglycemia II

This 'sawtooth-curve' indicates a severe form of hypoglycemia, though values do not actually drop below normal values. However, severe symptoms may occur.

Back to list ^

9. Flat curve (Source: Hypoglycemia; P. Airola)

Time [hours] 0 0.5 1 2 3 4 5 6
bG [mg/dl] 90 90 90 100 90 100 80 90
bG [mmol/l] 5.0 5.0 5.0 5.6 5.0 5.6 4.4 5.0

Flat curve

This is a flattened glucose tolerance curve. This curve may be characteric for people who conduct a dull, monotonous life. They complain about chronic fatigue, boredom, disinterest and loss of libido.

(Sounds like adrenal fatigue to me, probably caused by not eating enough food at all.)

10. Diabetes and hypoglycemia (Source: Hypoglycemia; P. Airola)

Time [hours] 0 0.5 1 2 3 4 5 6
bG [mg/dl] 100 160 220 160 85 60 50 85
bG [mmol/l] 5.6 8.9 12.2 8.9 4.7 3.3 2.8 4.7

Diabetes and hypoglycemia

This is a curve of a patient that is both diabetic and hypoglycemic. With such a curve
severe symptoms can be expected.

(Hell yeah! Hahaha. Even if the blood glucose will seem in the normal range often if you don't look for it at the right time. The damage from the stress will afflict you for a long time. Even if falling off the roof doesn't last long, it freaking hurts interminably; you have a damn good reason to be depressed and all!)

My experience and results

My test lasted only 2h instead of 5h, since I was told that it doesn't exist anymore. It didn't reveal the dangerous crash, but it showed that I go too high. I brought my own glucometer to make it last 5h and I saw myself go even higher than the test revealed, then the horrible crash very clearly. I was shaking so hard that I could hardly eat so I had to stop the test. I felt excruciating pain and exhaustion from the hypoglycemic shock for a whole week; even though I was on a sugar and grain free diet before and after the test.

It's the speed of the crash and not how low you get that is so damaging and distressing.

Too intense refined sugar is the cause not the cure, your pancreas can't handle something unnatural that he was never meant to cope with, it doesn't stand a chance and you'll fry it with diabetes type 2, or your liver if you rely on alcohol which hits you harder and faster than pure sugar.

It can go right back up if the pancreas squeeze reserves glycogen out of the liver with adrenalin... it's stressful and tire them. The blood sugar can get back up as quickly so that's why it's so hard to find out. You're not in the danger zone all the time, so you can look perfectly healthy if sampled at that moment. But you're not, because what companies offer you to eat rarely is.

You can't go wrong by choosing healthy living natural vegetables and cooking for yourself. Turning away from unbalanced refined chemicals, no matter what you have or not, will improve your body and mind even if you think you're healthy. If you're sick and miserable, it will heal you.

My results, simplified

It dropped and raised again before the test, I had to stop because I was in serious danger. It raised itself back at 4, but it took a lot out of me and I was having severe tremors making it hard to eat.

Time [hours] 0 0.5 1 2 3 4 5 6
bG [mg/dl] 92 209 223 195 101 56    
bG [mmol/l] 5.1 11.6 12.4 10.8 5.6 3.1    

Lisa's curve

My doctor called me to say that I was normal, but I compared it to the normal and it isn't so. When I met him he told me that I had glucose intolerance according to his machine. Then why the heck did he tell me that I was okay. They jump to conclusions before getting the data!

Lisa's curve - compared to normal - definitively not

I have hypoglycemia and diabetes at the same time. I didn't not see it coming... I didn't think it was possible, but now I see that it's hypoglycemia all the time, but trying to feed yourself with too much force when you need to be all the more gentle. It's actually the adrenal glands that are tired first. The pancreas store fuel with insulin and the adrenals take it out of the liver with adrenalin. If they're exhausted from stresses and lack of proper nutrients, they won't be able to keep you stable; you won't be able to take out your reserves. You'll crash and get fat with no energy. Smaller meals of slow digested living and moist fiber in vegetables with healthy fatty snacks like almonds is the simple solution.

Lisa's curve - Compared to  diabetes and hypoglycemia - perfect fit

I compared it to the normal, to see how far I crashed, and would have if my maximum didn't go beyond the upper limit. The result:

Lisa's curve superposed to the maximum normal - lower than 0, worst than death

From the file I wrote long ago, intended for my doctor:

To give you an idea how such an abrupt curve feels like, I superposed its peak with the normal (Min + Max) peaks.

Lisa’s peak = 12.4
Number of floors in the crash: 12.4 - 3.1 = 9.3

Normal Min’s Peak = 5.8 - 9.3 = -3.5
Normal Max’s Peak = 8.9 – 9.3 = -0.4

UNDER ZERO. If such a thing was possible, it would be worst than death. And this describes very well how it feels like to fall almost 10 floors under 1h30. It is very hard to be emotionally et physically stable with such a curve, it is very hard to bear on both aspects.
  • Around 5, I felt normal
  • At 10 I felt high as if I was on drugs to the point that I understand how people end up obese trying to feel this boosted all the time. The colors were shinier, but I was hyper, I couldn't sit still or I felt pain. I had to move to burn the energy and I almost ran around the hospital.
  • The happiness and burst of energy was short lived, because at 12 I started feeling miserable, curved on myself, I even cried.
  • Then back at 10 for an even briefer moment, as if a dark veil was taken off my eyes and soul.
  • It went normal again at 5. I was okay... but not for long, true hell was coming... the price in the balance for going too high.
  • When I went under the hypoglycemia limit of 3.3 and reached 3.1; I started feeling miserable again, but so much worst. I had a deep feeling of dread, I wanted to continue the test but I felt the panic that I was in genuine danger and that allowing my brain to be starved even further of glucose was too dangerous. Thankfully I understood the phenomena, so I could control my panic rather easily; but it was very unpleasant and disturbing. Unfortunately, I was trembling so intensely that it was hard to feed myself, my fingers kept moving away from my mouth on their own, very rapidly, which was distressing.
  • The problem is, as it would be to fall from actual floors I presume, that I didn’t feel completely better when I finally managed to get back up at 5. I was still shaken by the trauma. I felt drained, exhausted by the shocks. It lasted a week and made me more vulnerable to other problems.

    (After that I felt in pain all over for a week, even back on my sugar and grain free diet. The shock caused damage. It felt as if I literally fell of 9 floors and miraculously survived, or has been beaten up by a baseball bat. Every muscle, joint and nerve was a torture to move. I was bed ridden. It was a distressing despair even though I knew it would pass. Now I use 5g of vitamin C, added to my daily 4g. I divide it in 1g doses and take it every 20 minutes or so, I read that every hour is best to absorb it, but I can't wait when I'm suffering physically and mentally.)
My period was very abundant and I started to have symptoms of anemia. I had trouble breathing, but not the way it can occur during a panic attack, I didn’t have that. I truly was suffocating. I convinced the pharmacist to renew my iron pills without a prescription, and I ended up feeling back to normal after a couple of days. (But now I know that I actually need vitamin C to absorb iron and adding more iron isn't the solution. Extra vitamin C is needed during stress.)

Stupidly, I got discouraged and bought a sugar pie. (Craving sugar means craving vitamin C, I don't have sugar cravings now hat I take a lot.) It damaged my immune system so badly, since I never eat sugar, I got a cold. In the nose and throat, and descended deep with hard to expel mucus and still is here after a week. It’s been a long time since I ate that much sugar, and a long time since I got this sick. (I haven't been sick since because vitamin C make everything stronger and more elastic, so less likely to bruise, break, bleed and get infected, because white blood cell need to be full of vitamin C to be effective)

I always do feel horrible when I eat sugar but never this badly.

I do not want to pass this test again, so I really need the results to be believed and noted now. (But now I know that I could have done this at home. It doesn't matter if I'm labeled the craziest person on earth. The only thing that matters is me, how I see myself, the world that I build around me and the people I hold near. Being acknowledged by a competent doctor actually made me understand that I never needed it in the first place. I asked for the test and I was right... because I listened to my body and I didn't need some stranger's permission!!!)

I need help to help myself since way too long. (But in the end, when I turned away from asking people who can't possibly know how my body feels and started to respect it, to listen, to provide and find my ways with tries and errors... I succeeded where few doctors ever could, and certainly not with drugs, certainly not with those that unbalances your brain!)

I would really appreciate to have my condition recognized as having a real tangible physical source, for the psychological effect can be very troubling and could easily be misinterpreted and mistreated as psychiatric, my greatest fear; especially after reading about a girl who even got many electroshocks because she didn’t respond to medication.

(I do feel better and always carry my doctor's note about being hypoglycemic. But there's never a guarantee to be safe from grave incompetence. The best way to deal with this is to keep calm and not put your life in the hands of people who have such methods. Make sure to let your family know but it's best to keep to yourself, because people have a way to make things worst.)

I need help to know how to manage the condition before my pancreas gives in even more and end up as “3- Severe diabetes”; requiring medication for the rest of my life.

(Even the people with type 2 can heal with nutrition. In a mere week! I listened to my body so I never throw myself on cakes and booze to boost myself, I could see the damage soon after and it wasn't worth it. So it wouldn't have happened anyway to me. I happen to hate sugary things. But I got hypoglycemia and diabetes anyway, even with a healthy weight. Because the real cause is STRESS which causes adrenal fatigue.)

Why wait until it’s too late and critical. (Probably because the medicine is dangerous and it would be irresponsible to take it unless at death's door. But I saved myself even from that with nutrition!!! Medicine put me there!)

I wish help to help myself, to take a good care of myself.
(I never needed anyone's help to do it!)

This couldn’t be more healthy and sane. (It sure is no matter what fools claim pretending to be experts)

…Except being fully within the normal range, which I am not.
(I am now. Unless you consider being able to eat raw sugar like cereals and cake for breakfast as being cured. Then you'd have to consider being alive as a defect, because we're not meant to feed on bleached rocks! Even plants would die, even machine's motors would fry!)

Thank you.

(To my body, for saving my life, for never giving up on me. He kept telling me, with sadness and pain, even when I didn't want to listen... He guided me slowly and gently towards better things, step by step... I went back to my old ways often, to rapidly turn back to healthier choices, because I restarted feeling miserable right away. I did it less and less and before I knew it all grains, including corn, are out of my life; I didn't think it was possible. I simply went for what made me feel great and happy and noticed after it was done!)

If what is normal make people feel sheer physical and mental agony, and make them wish they were dead... Then I couldn't be more proud for being abnormal. I don't live in society's reality anymore. I discovered something more real: life itself.
