Common Questions and Answers about Glucose tolerance test fasting test

glucose

Avatar n tn I have been seeing an endocrinologist because I am constantly having low blood sugar readings and have had a high fasting blood glucose test of 8.3. My endocrinologist feels this may be due to my dysautonomia. She thought maybe reactive hypoglycemia because I am having low fasting glucose levels as well as high. I went for a 2hr OGTT today and I am feeling horrible after the test. My baseline was 4.8 @ 8:55 Given 75g of glucose to drink At 4.3 @ 9:25 At 4.8 @ 9:55 At 6.2 @ 10:25 At 6.
Avatar n tn I'm a 53 year old woman who just had a 3 hour glucose tolerance test, here are my results: Fasting - 106 1 hour - 210 2 hour - 230 3 hour - 167 I'm not sure if these results mean I'm a pre-diabetic or diabetic. Thank you for your help in advance.
Avatar n tn I had a glucose tolerance test and an insulin fasting (drinking the glucose drink) blood test done. I have seen my results but have not had them interpreted for me. My glucose fasting results came back within normal range but my insulin fasting results came back out of range for the 0,1, & 2 hour results. They were much higher than the normal ranges. Does this mean I have insulin resistance?
Avatar f tn With most fasting glucose tolerance test I think it was 10 hours only. Here when you have a fasting test the won't accept anything over 12 hours.
Avatar f tn for my next appointment i going to have the glucose tolerance test beverage and i have many question + I'm scared. help is my first time.
Avatar f tn Hey you guys..I will be six months on Tuesday and my next doctors appointment will be when I'm 26weeks and one day....I should be having my glucose tolerance test soon....I was wondering how was it for some of you? Like what was the process you had to go through? I'm just really curious before I have mime..
Avatar f tn I would recommend a OGTT (oral glucose tolerance test). My glucose was normal on fasting but abnormal two hours after drinking glucose. My fasting insulin was high and even higher two hours. (I would recommended insulin to be tested as well). In my case too much sugar in my diet lead to insulin resistance but hyperthyroidism caused impaired glucose tolerance.
Avatar n tn How much the sugar varies from before meal to after meal seems to be the issue here. The glucose tolerance test is the correct test to see how your body reacts to high levels of carbohydrates. It does sound to me as if you perhaps vary more than is ideal, for a low of 57 or high of 256 is something that even diabetics try to avoid.
Avatar f tn Is this the glucose tolerance test they do to test for gestational diabetes? Just did my 3hr one this morning. Don't remember it being that bad with my first but the drink made we want to gag this time!
875426 tn?1325528416 t matter if the patient has been fasting or the test is random [excludes OGTT [oral glucose tolerance test]]. A doctor may perform random glucose 'blood' testing to see if glucose varies widely throughout the day. Healthy peeps do not.
Avatar f tn I had milk and left over garlic bread not even an hour before I started the test. My results came out fine. They are only checking random glucose tolerance not fasting. The cutoff for the results are different so you don't need to worry. Normally Your body is supposed to produce insulin enough to cover your intake no matter how much you eat.
Avatar n tn "i had a blood sugar test (the finger ***** one) and my level was "perfect"." If you had soap or alcohol residue on your finger the test results would be imperfect. If the meter was old and mishandled, uncalibrated, test strips expired the test would results would be imperfect. The OGTT is one way to help determine blood glucose levels. Be sure to fast 8-10 hours prior. No food or colored liquids during this period. Don't cheat. Just a little bit skewers the results.
306245 tn?1244384967 The accepted ways of screening for diabetes are a fasting glucose, a random glucose(not as good) or a 2 hour glucose tolerance test. A HgB A1C is sometimes used by doctors but it is not widely accepted as a good screening measure, so I suggest a fasting or an OGTT. You should also have a thyroid screen(TSH) done. Fasting glucose is not perfect, so yes you can have a "false negative" in terms of saying you have no abnormalities in glucose handling.
975514 tn?1324997938 I left out in my previous post, an OGTT [Oral Glucose Tolerance Test] can be used in place of an fasting test. Sometimes doctors do both to verify one to test with another.
915119 tn?1341948989 I have my appointment on the 2nd of April. I will ask why. The lady who drew the blood said it was different from all the others she had done. She didn't know why they would want a "Fasting Blood Sugar" test and then a "Glucose Tolerance Test". That kind of concerned me. I just hope everything is ok.
Avatar f tn You do have to drink a really sweet drink and then wait for an hour. You won't be able to leave the premises so bring something to do. You don't need to fast prior to the test. It's to see how your body metabolizes glucose. If your results fall within 'normal' you should be good to go. If not you'll have to do another glucose tolerance test. For this one you do have to fast (12 hours) and it's usually a 2 hour test.
Avatar f tn There was a one hour version of the Glucose Tolerance Test? No fair. I had the full fast, sit around a hospital for 2 hours of my working day one. All clesr tho.
Avatar f tn Because if your glucose is too on the screening test you will need to take the full glucose tolerance test (diagnostic test). Which is a pain. I failed my 1 hour test (1 point too high) so had to do the full three hour test. For this you do have to fast for at least 8-10 hours before the test. You have to drink twice as much sugar water (100 gm). And you have to wait there while they take multiple blood samples in that ttime.
Avatar f tn m going to be 24 weeks tomorrow and I have an appointment for the 3h glucose tolerance test. Its my 4th time since I am pregnant. Just because one of my results was not normal. I wonder why the doctor dont start to treat me for high glucose , instead I have to do this over and over again.... I am so tired of fasting and doing this test.... anyone in a similar situation?
Avatar m tn Till now I have no history of either diabetes or hypertension. I am 26 weeks pregnant and have to undergo glucose tolerance test (GTT). It is usually advised to take the test early morning as metabolism falls in afternoon due to diurnal rhythm. My problem is that I have an upside routine for the past 5 months, I sleep during day around 8-9 AM and wake up at 5-6 PM in the evening. Can I take my GTT in evening, I assume that my biological clock is now set according to my sleep cycle?
