Fasting Before Glucose Tolerance 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. We can measure Insulin to determine how much effort pancreas is making to control sugars. Think of glucose as speedometer & Insulin as tachometer (hgba1c is avg trip speed - ask a car nut if this doesn't make sense). ...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

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

Fasting glucose 85. then GTT hour 1glucose 84, hour 2 glucose 94. what would cause this odd response?
Normal variability: So for that test, you basically get a dose of glucose to see if your blood sugar remains elevated. Our bodies respond very quickly to glucose, meaning that it gets taken up by our muscles and liver almost immediately after it enters the blood stream. Our body's "thermostat" is set to keep the blood sugar level between 70-99. Over 100 indicates a problem with glucose metabolism. Yours is normal. ...Read moreSee 1 more doctor answer

Many people manage looser but i try to get better control without risking low blood sugars which can be very bad so be careful and work with your doctor closely. ...Read more
Newer recommendation: Is that non-diabetic pregnant women undergo a 2-hour 75-gram oral glucose tolerance test at 24-28 weeks of gestation. Women should be fasting for this test, and a fasting glucose level should be included. If any one of the following values are abnormal, you have gestational diabetes: fasting at 92 or above (mg/dl), one-hour at 180 or above, two-hour at 153 or above. ...Read more

Methods: Was either of the tests done in a CLIA accredited laboratory? It so, you can rely on that. If one of the tests was done on a Point of Care instrument and the other on a regular analyzer, the latter is more reliable. It is better to have your doctor order the tests and send the samples to a reputable lab. 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.

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
