Doctor insights on: Glucose Tolerance Fbs 2hr Pp

Tolerance (Definition)

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

Time to get serious: You have normal glucose tolerance. Your fasting and 2 hr glu is not quite at the level of "impaired". Your insulin levels are on the high side, suggesting insulin resistance. Now is the time to start getting your weight under control, proper diet, and physical activity. Talk to your doctor about your particular situation. ...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?

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 more

Blood glucose post prandial is 81.00 but serum insulin is2.7?

What's your question: Why was your serum Insulin checked in first place? What's the reference range given for insulin? How did your ordering physician interpret test for you? Why was blood drawn after a meal b/c you need to be fasting in order to calculate your homa-ir? As you can see, too many questions need to be addressed before we even get to your question, whatever it is! ...Read more

High normal fasting gluc and HgA1c. Normal 2 hour post prandial readings. Can fatty liver be causing my "pre-diabetic" state?

High normal fasting gluc and HgA1c.  Normal 2 hour post prandial readings.  Can fatty liver be causing my "pre-diabetic" state?

Pre-diabetic?: Your lab values does not suggest pre-diabetes but pre-diabetic state can cause fatty liver not the other way around. Decrease your carbohydrate intake and eat low fat diet to decrease the risk starting today. It also will help you to decrease the risk of arteriosclerotic cardiovascular disease. Contact me if you have further questions. Hope this helps. ...Read more

HbA1C: HbA1C levels of 6.2 and 6.0 with normal fasting blood sugar and low 2 hour postprandial blood sugar suggest an increased risk for diabetes. These numbers are not diagnostic of diabetes. ...Read more

Type II diabetic, blood insulin last test (NOT glucose)=29.5 On lantus (insulin glargine) 62 units, humalog 17 units. Am I still producing endogenous insulin?

Need C-peptide test: Since exogenous (injected) insulin will show on a blood test, C-peptide should be measured to assess for endogenous insulin. Proinsulin is made by the pancreas, then cleaved into C-peptide & insulin. Exogenous insulin has no C-peptide. ...Read more

My bl sugar level drops to 50 3 h after eating,normal insulin, c-peptide, liver enzymes' levels,family history of diabetes,is it reactive hypoglycemia?

My bl sugar level drops to 50 3 h after eating,normal insulin, c-peptide, liver enzymes' levels,family history of diabetes,is it reactive hypoglycemia?

Reactive hypoglycemi: yes. It is. Whenever you eat ready sugars or simple sugars( made with table sugar, juices) your body releases lots of insulin . Your sugars get absorbed mostly from stmach and there is still insulin in the blood that continue to lower your sugar.you should avoid ready sugars and take more complex carbs. Along with proteins. You most likely will be developing diabetes in near future. So watch !! ...Read more

Does this suggest diabetes? Glucose - 62, Glucose Fasting - 69, Insulin Fasting

Does this suggest diabetes? Glucose - 62, Glucose Fasting - 69, Insulin Fasting

Nope: Those are excellent numbers, even going to a little low. Diabetes is not a concern until your fasting glucose starts going over 100, and it isn't called diabetes until higher than that. A1c would also be much higher (6.5% or above is diabetes, 5.7-6.4% is increased risk, 4-5.6% is normal). Good luck! ...Read more

Fasting glucose 85. then GTT hour 1glucose 84, hour 2 glucose 94. what would cause this odd response?

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 more

Blood Sugar (Definition)

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

Glucose (Definition)

Glucose is the basic sugar molecule and the source of energy throughout the living kingdom. We are programmed to easily detect it by taste in our foods as it is desirable but can be overdone with the modern diet. It gets out of control ...Read more
