Glucose tolerance and insulin sensitivity

Common Questions and Answers about Glucose tolerance and insulin sensitivity

glucose

Avatar n tn Chromium appears to play a role in normal insulin function and glucose utilization, and some investigators have suggested that it increases insulin sensitivity and glucose tolerance and decreases blood glucose levels in certain diabetics, possibly those with low chromium levels. However, others have not corroborated these findings, and a few have even reported a negative effect on glucose tolerance and blood levels.
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?
1033523 tn?1258035082 Normally there are no antibodies to insulin. If you have IgG and IgM antibodies against insulin, your body reacts as if the insulin is foreign. This may make insulin less effective, or neutralize it. Normal values are 5-20 mcU/mL while fasting; values may differ per laboratory. Check your lab results paperwork for the exact ranges. As far as daily testing, it's to early to tell until the doctor exams your test results. Good luck and let us know everything goes.
Avatar f tn When you say that metformin works by increasing sensitivity to insulin, and it doesn´t affect the amount of insulin your body releases, does that mean that my body could be producing high amounts of insulin, which now can be used due to metformin, and therefore my glucose levels decrease too much? My fasting numbers are around 92. I haven´t really measured my numbers before I eat, I will do that. Within what range should my glucose levels be before I eat?
Avatar f tn The most common cause of small fibre peripheral neuropathy listed is diabetes or glucose intolerance. I have permanent nerve damage from B12 deficiency and insulin resistance/impaired glucose tolerance. I've never had abnormal fasting glucose levels but my glucose went too high however after I drank a glass of glucose (2 hour oral glucose tolerance test - OGTT) which showed I had impaired glucose tolerance.
Avatar n tn I am reading on how the pancreas produces insulin and that beta cells make and secrete insulin. I take 25 mg of atenolol 2x daily. I do know they can block the symptoms of hypoglycemia...But do they have any effect on the beta cells.
Avatar m tn You have been told that you are borderline diabetic, or you had an abnormal glucose tolerance test. You probably have elevated insulin, and you may also have elevated LH (luteinizing hormone). You are probably overweight, although you may be normal weight. Normal-weight insulin resistance can occur in the years following dieting or eating disorder. Treatment ideas: The first step is to quit sugar.
Avatar f tn I went back to the doctor who found my numbers had not improved but worsened after a year and told me I had impaired glucose tolerance and that I had to keep on taking 500mg metformin. She didn´t understand why my numbers didn´t improve, since I had lost 40lbs and didn´t have family history of diabetes. Another important thing to mention, is that I have been weaning from the cymbalta (antidepressant).
Avatar n tn 90 or less), buffalo hump (over 12 years), acanthosis nigricans (brown to black velvety hyperpigmentation of the skin usually found in body folds), skin tags, grown 3cm (i blame this symptom on insulin resistance). My fasting glucose and two hour glucose tolerance test were both in normal range. *** "Can you be insulin resistant and still have normal blood sugars? Yes!
Avatar f tn 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.
6938807 tn?1395163288 My labs show basal insulin 39 mU/L (6 - 22) and 2 hours after drinking glucose (glucose tolerance test) insulin was 184 mU/L (15 - 65). My cause was eating too much refined sugar but worsened by prolonged hyperthyroidism. Excerpt from Women To Women: What Is Insulin Resistance?... "Why all the concern about insulin resistance? Over 80 million Americans suffer from insulin resistance, and it appears to sit at the center of a web of related health problems.
1452593 tn?1285187324 Two hour PC (Postprandial glucose test) where they make you fast for 8 hours, take a blood sample to get your glucose reading, and then you eat a meal and then they test your blood-sugar again (another blood sample). You have to do insulin or your sugar goes through the roof. Beats me....
Avatar f tn In a person without diabetes, the glucose levels in the blood rise following drinking the glucose drink, but then then fall quickly back to normal (because insulin is produced in response to the glucose, and the insulin has a normal effect of lowing blood glucose.
Avatar m tn Just ask for that and maybe an oral glucose tolerance test as well. The insulin levels (insulin is a hormone) will tell you whether the insulin is high in the blood (which is very likely if she has PCOS, the pancreas is overactive and secrets much more insulin than needed). The glucose tolerance test will tell you whether she is already insulin resistant. If she has PCOS, these two tests are a must, since the danger of becoming diabetic is rather high.
390388 tn?1279636213 So a glucose tolerance test has to be done to tell whether or not the cells are getting the glucose. If the blood sugar is too high after a meal then the glucose is still floating around in the blood stream and not getting to the cells as it should. The pancreas will keep pumping out insulin so eventually it goes back down to a normal level and that explains why it's not uncommon for people to be a type 2 diabetic for years and not know it.
649848 tn?1534633700 I, recently, had a Glucose Tolerance Test due to fluctuating fasting glucose and weight issues, but the worst symptom is tiredness/afternoon crash. The results of the GTT were as follows: Fasting: 97 1 hr: 165 2 hr: 124 3 hr: 48 L 4 hr: 56 L Over the past 5 years, my fasting glucose levels have ranged from around 97 or 98 all the way up to 125, but never over 125. My A1c has ranged from 5.5 to 5.8 over the same period and my doctor has said I'm pre-diabetic.
Avatar n tn Have you had a glucose tolerance test to see if your body produces too much insulin as a reaction when you eat? This is a different test from having a simple blood sugar test -- you must drink a sugary solution and blood is drawn several times to see how your body is reacting. Unfortunately, when people have what is called REACTIVE HYPOGLYCEMIA (when the body reacts by over-producing insulin, which causes hypoglycemia), it can be difficult to show in a test.
Avatar n tn if normal blood insulin levels are 5-20 and my fasting insulin level was 3 would that be considered a normal result?
Avatar n tn ve read, *high* levels of insulin can be a problem because that can signal insulin resistance where the body resists the effects of insulin and stresses the pancreas to produce more & more. This is often present in overweight folks who are pre-diabetic or already have developed diabetes, as described here: http://diabetes.niddk.nih.
1093971 tn?1257833640 They reasoned glucosamine is ten times as powerful as regular glucose thus causing insulin resistance. Insulin resistance can increase fasting blood sugar levels and exacerbate glucose tolerance. Others reported taking glucosamine may not affect blood glucose levels directly, but some evidence from both animal and human studies suggested that it may promote insulin resistance over time. Over what time and when this would occur varies per individual.
1253246 tn?1332073310 There’s another test called ‘HOMA-IR’ as well; this is the ratio between blood serum glucose and insulin, and actually defines insulin resistance. The test Denise mentioned is called a ‘glucose tolerance’ test. Good luck; do what’s necessary to avoid developing diabetes if it looks like an issue; you really don’t want to deal with that if you can avoid it.
