Fasting For Glucose Tolerance Test
My glucose tolerance test results are:
fasting: 100 mg/dl, 1hr: 148mg/dl, 2hr: 128 mg/dl. My hbc1a : 5.7.
I am concerned....Am i prediabetes?
Probably not: The fasting glucose of 100 and hba1c of 5.7 are borderline high, the other tests are normal. Diabetes is defined by fasting glucose above 125 or post prandial glucose above 200, or hba1c above 6.5%. People with prediabetes will typically also have triglycerides above 150, HDL cholesterol under 50 in a female, hypertension, and obesity. ...Read more
When one takes a drug, such as heroin or alcohol, repeatedly, 'tolerance' develops because more of the drug is needed to give the same effect on the body/brain; e.g. Liver enzymes r stimulated to metabolize the drug faster and faster. 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
Non diabetic normal glucose tolerance test A1c between 4.9 to 5.6 but I have dawn phenomenon every morning if i test at 9 hrs fasting why?
Glucose tolerance test negative but every morning I wake up with fasting sugar 104-108 . If I eat sugar during day sugar not high. So what do I do?
More testing needed: You are prob a pre-diabetic or have a metabolic syndrome. You need further testing to confirm. Ask your doctor for a Hemoglobin A1C test. It gives you the ave blood glucose over the last 3 months. Normal is <5.7, borderline is 5.7-6.4, and 6.5 or higher is diabetes. Start checking your fingersticks intermittently. Some fasting and some 2 hrs after a meal. AM goal is <100, after meal is <180 ...Read moreSee 1 more doctor answer
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 moreSee 1 more doctor answer
Recently bloodwork for fasting insulin. How is this different that a glucose tolerance test or a fasting glucose test?
Different tests: Insulin & glucose are 2 different ways to measure diabetes. Insulin is produced by pancreas to keep sugars under control. We measure glucose to see how well sugars are controlled. Think of glucose as speedometer & Insulin as tachometer (hgba1c is avg trip speed - ask a car nut if this doesn't make sense). Glucose tolerance test requires drinking sugar whereas other 2 tests don't. ...Read more
I am prediabetic with higher blood sugar and insulin levels. L just had a 3 hour glucose tolerance test. Fasting sugar is 63, insulin is 2. Meaning?
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 moreSee 1 more doctor answer
Suffering from pcos but glucose tolerance test 100 mg n fasting sugar tests are normal still can I take metforminam i insulin resistant still ?
Yes: Insulin resistance is the basic metabolic cause of pcos, and metformin is generally the best treatment for Insulin resistance and pcos. You want to emphasize diet, exercise and weight loss - plus metformin if indicated- so that you improve your weight and Insulin resistance before your blood sugar gets above normal. ...Read more
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 blood sugar concentration or blood glucose level is the amount of glucose (sugar) present in the blood of a human or animal. 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
