Tolerance (Definition)

There may be a strong genetic predisposition to addiction, some studies suggesting that 1 of 10 people will become dependent on alcohol or some ...Read more

Doesn't matter: The numbers aren't really important or valuable. If you're overweight and have high glucose (particularly with a positive family history) you need education, diet, exercise, weight reductio and maybe medication -- not just a diagnosis. The diagnosis doesn't help you get healthier. ...Read more

Im 24 weeks preg. I did the glucose tolerance test: 75g of glucose, test after two hours 132mg/dl. Should i worry? What should I do to reduce it?

Normal: You did a screening test with 75g of glucose. A result under 140 is considered normal. If it was above 140 you would have had a full glucose tolerance test with 100 gm. You do not need to worry. ...Read more

Glucose tolerance test: I passed but 1hr-173; 2hr-167; 3hr-103. I walked during last hour. Would walking make me pass when I should have failed?

Not likely: Even though you did not follow the protocol, given the other results, you are not likely to have failed the test had you stayed put as required. For good health - Have a diet rich in fresh vegetables, fruits, whole grains, low fat milk and milk products, nuts, beans, legumes, lentils and small amounts of lean meats. Avoid saturated fats. Exercise at least 150 minutes/week and increase the intensity of exercise gradually. Do not use tobacco, alcohol, weed or street drugs in any form. Practice safe sex. ...Read more

My glucose tolerance test results : fasting = 105; 1 hr. post swallow = 188; 2 hr. post = 158; 3 hr. post = 55; 4 hr. post = 57; a paradox? A1c = 5.4%

IFG & IGT: Hi. You meet criteria for pre-diabetes on the basis of impaired fasting glucose (IFG) and impaired glucose tolerance (IGT). Your A1c is not yet abnormal, but you see how your glucose goes into the 50's a few hours after a challenge; that offsets the A1c, making it a less sensitive test for diabetes. Eat healthy, exercise regularly, and talk with your doc about possible medications to prevent diabe ...Read more

Confused. got 1 touch machine two weeks ago, readings are frequently as high as 20 mmol, but did glucose tolerance test and it was normal?? what do?

Lab test: Glucometer is not used for diagnosis. If you want to know if you have diabetes, ask your doctor to order fasting glucose and an A1c. If bs is over 126 fasting and a1c is over 6.5, then you have diabetes. Good luck. ...Read more

I got a glucose tolerance test, now what?

Screen for diabetes: A normal test can help you feel better that you don't have diabetes. An abnormal test can fall into two buckets - either borderline or frankly diabetic. The cutoffs for "abnormal" are different depending on why you had the test. This is a good thing to speak to the ordering physician about. ...Read more

The body naturally tightly regulates blood glucose levels as a part of metabolic homeostasis. Glucose is the primary source of energy for the body's cells, and blood lipids (in the form of fats and oils) are primarily ...Read more
