You are not supposed to eat anything for 12 hours before the test….or the results will be off…
Will not eating regularly before an Oral Glucose Tolerance Test affect your results?

Glucagons Expire
Diabetics on insulin or oral drugs that cause increased insulin production should have someone around who can administer glucagon in cases of severe hypoglycemia.
Transcript: Like most insulin dependent diabetics, I’ve got a glucagon on hand. And, uh, I actually have three glucagons. I got two from the hospital, and then I ordered another one about eight months ago. And, uh, I had umed that the two from the hospital were expiring at the same time, which is, uh, November of 2007. But I just looked at the one in my mother’s bedroom, which is the only one that’s likely to be used, and it expired in July. So I replaced it with my newest one. Glucagon is a hormone that signals to the liver to dump all of the- uh to dump glucose. The glucagon injections generally signal it to release ALL of the sugar that its storing, but your body normally secretes smaller amounts of glucagon, with peaks at mealtimes. More dramatic peaks in diabetics. Type 1 diabetics especially tend to have unusual glucagon production although we do still tend to HAVE glucagon production. In any case, in the case of severe low blood sugar, severe hypoglycemia, you should have a glucagon kit, red or orange (I know the color’s kinda bad on here)and uh someone else can administer this if you’ve passed out. If you’re just having trouble eating, they can use it. They should first turn you over on your side- its good to have whoever’s around trained in this- turn you over on your side because if the glucagon injection is a little too much or whatever, you can throw up and you really don’t want to choke on your throw up. That’s a nasty way to die. Also very preventable. So, uh, they should turn you on your side. And then they’ve got, in here they’ve got, a glucagon needle, which is intramuscular length needle, it’s considerably longer than the insulin needles, and they’ve got this little vial, which has a little white pill in it. And they’re gonna uncap this, uh, thing, and they’ve got this big old needle here. Lemme see if I can get it to show up better. No I don’t think you can see a needle. Oh well. It’s- trust me, it’s large. You’re gonna uncap the glucagon. You’re gonna inject the water that’s in the needle into the glucagon, sticking only part of the needle inside the vial, not the whole thing. Then they’re gonna shake up, you’re gonna roll the mix, not shake it up, my bad. Then draw the mixture back out into the syringe. If you’re dealing with someone who weighs more than about fifty pounds, they say go for the whole thing. If not, half the thing. It’s probably not going to make a difference. Um, yeah. You can’t overdose on glucagon. It’ll give you a crazy headache, and uh, it can make you throw up, but it’s not likely to kill you [editing note: it can kill only in cases of allergic reactions to the mixture]. And then they can just inject it anywhere. If you’re really really low, circulation to your fat can be cut off, so that it’s better to inject it into a muscle, but if it goes into the fat, then it’s probable that you’re not so low that it’s going to be a problem. It’ll act a little faster if it goes into muscle. If it goes into a vein, that’s also not a problem, it’s gonna act a little faster that way, and you might have a little more of the side effects of glucagon, but it’s still liable to save your life. Uh, so, I expect you check the expiration dates. Often the expiration date on the syringe with the liquid on it is different from the expiration date on the little glucagon pill. On this particular one, I’ve got an expiration date of November 2007 on the pill, an’ an expiration date of December 2007 on the bottle. The container itself might also have an expiration date. You wanna throw it out when it- not necessarily throw it out, practice with it- soon as the earliest of the expiration dates has passed. Uh, yeah. I’ve, I’ve never had to use a glucagon. But I know I want an unexpired one on hand. Also as a person living alone, I’m not that likely to have anybody actually use it [editing note: my mother checks on me in the mornings sometimes and might use one if I was nonresponsive then]. But… it’s security. It’s good to have on hand. Saves lives every now and then. Check and see whether yours is expired.

Hypoglycemia
Hypoglycaemia or hypoglycemia is the medical term for a pathologic state produced by a lower than normal level of blood glucose. The term hypoglycemia literally means “under-sweet blood” (Gr. hypo-, glykys, haima).
Hypoglycemia can produce a variety of symptoms and effects but the principal problems arise from an inadequate supply of glucose as fuel to the brain, resulting in impairment of function (neuroglycopenia). Derangements of function can range from vaguely “feeling bad” to coma, seizures, and (rarely) permanent brain damage or death. Hypoglycemia can arise from many causes and can occur at any age. It also sometimes occurs at random.
The most common forms of moderate and severe hypoglycemia occur as a complication of treatment of diabetes mellitus treated with insulin or less frequently with certain oral medications. Hypoglycemia is usually treated by the ingestion or administration of dextrose, or foods quickly digestible to glucose.
Endocrinologists (specialists in hormones, including those which regulate glucose metabolism) typically consider the following criteria (referred to as Whipple’s triad) as proving that individual’s symptoms can be attributed to hypoglycemia:
1. Symptoms known to be caused by hypoglycemia
2. Low glucose at the time the symptoms occur
3. Reversal or improvement of symptoms or problems when the glucose is restored to normal
However, not everyone has accepted these suggested diagnostic criteria, and even the level of glucose low enough to define hypoglycemia has been a source of controversy in several contexts. For many purposes, plasma glucose levels below 70 mg/dl or 3.9 mmol/L are considered hypoglycemic; these issues are detailed below.

Any adverse effects on the fetus from oral glucose tolerance test?
My mom was forced to take an oral glucose tolerance test (the results were negative) during her pregnancy with me even though her blood sample was normal. I’ve always had health issues such as lightheadedness, dizziness, blurred vision, fainting episodes, bloody noses, etc. without apparent cause. In spite of these issues, I have always been called healthy. I also have always enjoyed a healthy weight, exercise, and diet. I recently had a test done that came back negative for all sorts of things, such as diabetes and disorders of the thyroid (should have been a relief but wasn’t since no answers). I am concerned that I am not receiving treatment for these issues, I am now a young adult and they are drastically effecting my ability to function as such.
Does anyone have any idea? I greatly appreciate your time and any feedback, thanks!
My mom began feeling very sick during the test, and felt lightheaded immediately after.
No, absolutely none at all. It was extremely important that she had it because gestational diabetes is very serious, and if she had had it, it would have needed to be treated through the pregnancy to keep YOU safe.
Your health problems are in no way related to that.
Sounds like you need more detailed testing, and possibly get to some specialists. Good luck.

Oral Glucose Tolerance Test results?
I made an Oral Glucose Tolerance test.
The results was very very interesting and I am now very nervous about that results.
Fasting blook sugar : 4.20 mmol
1st hour after the glucose take – 24.46 mmol !!!
2hd hour ……………….. 5.17 mmol
I saw that in USA are other measure for blood suger.
So just mine multiply by 18 and will receive the US ones.
Thanks for your answer.
Best Wishes
Ivo
5 Months ago I made also OGTT.
Results were :
fasting – 4 mmol
1st hour – 9.2
2nd hour – 7.2
Blood was taken from my finger(capillary).All 2 test were with 75 gr. glucose.
I am 28 years old – male.
Yup, you’re becoming insulin resistant, alright. No worries, though. It’s just time to be proactive (or else). Learn all you can about a healthy, nutritious diet plan, and exercise at least a half hour a day. More useful info on my diabetes info page:

Does anyone know what that liquid tastes like during oral glucose tolerance test?
I am 7 months pregnant and I am having this test done Monday. Anyone that has been through this before can you PLEASE tell me how it taste?
Actually, it doesn’t taste bad. I have had an orange flavored one (kinda tasted like orange soda) and a fruit punch one that was good.

Potentially Fatal Glucose Monitoring Errors with Icodextrin
October 2008- The Institute for Safe Medication Practices (ISMP) is warning again about the possibility of potentially fatal glucose monitoring errors in patients receiving products that contain other sugars. These include oral xylose, parenterals that contain maltose or galactose, and peritoneal dialysis solutions that contain icodextrin. This issue was also reported in an earlier edition of FDA Patient Safety News.
The problem is that some point-of-care glucose meters use a type of test strip that cannot distinguish between glucose and other sugars. So in these cases, the meter’s reading of the test strip will reflect both the patient’s actual blood glucose and the other sugar the patient has received. This falsely elevated reading can lead to aggressive insulin treatment, which can result in hypoglycemic shock and death.
The latest ISMP report concentrates on Extraneal, a peritoneal dialysis solution containing icodextrin, which is metabolized in the body to maltose. The ISMP report notes that FDA has received 18 reports of hypoglycemic adverse events ociated with Extraneal since it was first marketed in 2002. In three cases, the patient or a family member told the hospital staff about the potential problem, but the staff still relied on erroneous readings from portable monitors.
In one of the reported cases, a 62 year-old hospitalized dialysis patient on Extraneal therapy died from severe hypoglycemia because his treatment was based on falsely elevated glucose readings from an inappropriate meter. This occurred despite glucose readings from the hospital lab that were strikingly lower than those produced by the meter.
Test strips that cannot distinguish between glucose and other sugars contain reagents called GDH-PQQ or GDO. Other types of meters use reagents that are capable of distinguishing glucose from the other sugars. These reagents are called GDH-NAD, GDH-FAD, glucose oxidase and glucose hexokinase. It is important to check the package insert that comes with the test strips to determine which type of reagent they contain.
Here is what ISMP recommends to prevent these glucose monitoring errors in hospitals. Consider using only glucose meters that use test strips that can distinguish between glucose and other sugars. If you use meters and strips that cannot distinguish between the sugars, take these additional precautions:
•On admission and periodically during the hospital stay, find out whether the patient is receiving medications containing other sugars. If so, monitor glucose using only hospital laboratory methods.
•Periodically verify point-of-care blood glucose readings with laboratory results. This can detect errors in glucose meter readings early enough to prevent harm. This is especially important in patients who are unconscious or unable to communicate, since it may be difficult to ascertain the symptoms of hypoglycemia or the medication history.
•Educate the staff about this potentially fatal problem, and consider safeguards such as drug interaction alerts in computer order entry systems, patient profiles and charts.

if you eat a lot more than usual before your oral glucose tolerance test, what happens to the result?
i am aware that i have to fast for 8-10hrs before going for the test, but what if before the 8-10hrs, i eat a very huge meal? is it going to abnormalize the result?
Just eat normally.
But if you are planning a big meal, move it back so that you are fasting for 10-12 hours before the test.
it also helps to schedule the test for the first thing in the morning, so that you do not have to wait so long to go eat.
At that rate, if you can get an 8:30 AM appointment for the test, you can schedule you large meal for 7PM the previous night.
ALSO:
ASK the doctor to do an A1C test. You do NOT have to fast before you take this test. this test gives you a 90-day "average" on how bad your diabetes is, or how well you are controlling it.
