If you met most of the above-said criteria, then you need to undergo for diabetes screening.
If the test result indicates that a person has diabetes, then should be re-confirming with a second test on a different day. Fasting Plasma Glucose (FPG) – is a blood-glucose test after not having anything to eat or drink (except water - even do not drink a lot of water before the test) a minimum of eight hours before the test.
Oral glucose tolerance test (OGTT) – or glucose challenge test is a blood-glucose test before, and two hours after you eat a carbohydrate-rich food or drink a special sweet drink.
Random plasma glucose test – is a blood-glucose test at any time of the day no restrictions. Glycated hemoglobin test (A1C) – is a test done at any time, there is no fast or drink anything, and it measures the average BS for the past two to three months. People getting different results between tests may indicate diabetes is trying to get through the system.
For many, making few lifestyle changes such as losing some weight, increase in physical activity and eat healthy can help reverse diabetes or at least delay its onset.
Elevated 1-hour level proves significant despite 2-hour level within normal glucose tolerance range.
The current approach of screening for type 2 diabetes using the fasting metabolic state, while convenient, is not effective. Evidence is accumulating that most people with a 54%–67% range of impaired glucose tolerance have fasting glucose in the normal range. An elevated 2-hour glucose level indicated increased mortality risk, independent of the 1-hour level. One-hour post-load plasma glucose level during the OGTT predicts mortality: observations from the Israel Study of Glucose Intolerance, Obesity and Hypertension. Legumes – chickpeas, kidney beans, black bean, navy beans and lentils – have a plethora of health benefits. They're foods with big health benefits, yet they're often neglected, relegated to the back of the kitchen cupboard.
Now, a new study in the August issue of Diabetologia adds to the growing evidence that beans are good for you, especially if you have diabetes. More than two million Canadians have diabetes, a number that's expected to rise to three million by the end of 2010. For people who have diabetes, controlling blood glucose is paramount in preventing long-term complications such as heart disease, nerve damage and kidney disease.
Diet is a key to blood sugar management, whether a person is taking diabetes medication or not.
Research even suggests that eating legumes can substantially reduce the risk of developing Type 2 diabetes. When eaten on their own or part of a high-fibre or low-glycemic diet, legumes lowered fasting glucose and insulin levels.
Legumes are an excellent source of fibre and vegetable protein, and contain slowly absorbed carbohydrate. Legumes are also a good source of many phytochemicals, some of which may aid in blood sugar control.

If you prefer the convenience of canned legumes, you'll only have to drain them in a colander and rinse under cool running water to remove sodium and many of the carbohydrates that produce intestinal gas..
While beans don't always cause gas, some people are more sensitive to this potential side effect.
Health Canada advises eating beans and lentils in place of meat to reduce saturate fat and increase fibre. Leslie Beck, a Toronto-based dietitian at the Medcan Clinic, is on CTV's Canada AM every Wednesday.
Of the 1,713 tests which would have been judged normal strictly on the basis of glucose tolerance, 50% were demonstrated abnormal on the basis of insulin tolerance, and another 14% were borderline results. Remember that all these people were referred because of suspicion of diabetes, so the high numbers should not be so surprising, but what the above data shows is that of the 1,713 cases, out of 3,650 which would have been judged normal by only glucose tolerance test criteria, the insulin test showed that only one third of them really were normal.
Looking at the overall group of 3,650 people referred because of suspicion of diabetes, the usual glucose tolerance test criteria would have found that 1713 were normal.
Unfortunately, we’re not going to be able to do an EEG and pick up the abnormal brain wave response. Detection of Diabetes Mellitus, In Situ (occult diabetes), Kraft, Joseph R., Laboratory Medicine, Volume VI, #2, pages 10-22, February 1975. Diabetes diagnosing tests are Fasting Plasma Glucose FPG test, Oral Glucose Tolerance OGT test (most emphasized), Random plasma glucose test (not reliable) and A1C. Where blood-glucose levels have not risen high enough or not yet stabilizes to be higher level to show up on every test result. Meta-analysis of 20 different European studies showed as many as 31% of those who were have diabetes according to post-challenge plasma glucose had normal fasting values and therefore would not have been detected by a screening procedure based upon fasting glucose measurements alone. The researchers conclude that present findings, in conjunction with the other observations, suggest that individuals at high risk for developing diabetes could be identified earlier by measuring the 1-hour postload glucose level. However, when the 2-h level is in the impaired glucose tolerance range, the hazard for mortality rises significantly independent of the 1-h value.
Legumes - chickpeas, kidney beans, black beans, navy beans, lentils - help regulate blood sugar, lower cholesterol and blood pressure, and guard against heart attack and cancer. What's more, the incidence of impaired fasting glucose, or pre-diabetes, is also on the rise.
For people with pre-diabetes, managing blood glucose levels can prevent a future diagnosis of Type 2 diabetes. When added to a high-fibre diet or a low-glycemic diet (one with complex carbohydrates that allow the slow release of sugar into the bloodstream), legumes have been found to lower fasting blood glucose and insulin readings. Michael's Hospital in Toronto analyzed the results of 41 randomized controlled experimental trials to assess the evidence that beans benefit blood sugar control. The review included studies measuring blood glucose control when legumes were eaten alone, when added to a high-fibre diet, or when part of a low-glycemic diet. Legumes were also found to improve glycosylated hemoglobin (HbA1c), a marker for longer-term blood sugar control. With their low glycemic index, legumes slow the rise in blood sugar after a meal, fending off an outpouring of insulin. Studies have revealed that eating legumes can help lower LDL (bad) cholesterol and reduce elevated blood pressure, and may even cut the risk of prostate and breast cancers.

If you're new to legumes, start slowly and gradually increase your portion size over a few weeks to give your gut time to adjust. The Canadian Diabetes Association recommends adding legumes to your diet to help lower the glycemic index and increase the fibre content of your diet. Use half the amount of lean ground meat you normally would and make up the difference with beans. Bringing to bear the insulin tolerance test, two thirds of these so-called “normal” tests were found to be latent diabetic. Hudspeth did not have a breakdown of the different types of patterns, just this information alone should enable us to better pick up hypoglycemic symptomatology in the absence of abnormal glucose tolerance test values.
Engelgau et al (2000) stated that one of the criteria for appropriate screening is that the tests should detect the preclinical stage of disease and that the tests be shown to be acceptable and reliable. In an analysis over more than 30 years of a large population assessed for all-cause mortality researchers, it was found that an elevated 2-hour glucose level indicated increased mortality risk, independent of the 1-hour level. Instead, they don't know how to incorporate them into their diet, aside from making chili or opening a can of baked beans. If that fails, try Beano, a digestive enzyme supplement available in drug stores that breaks down the gas-causing sugars. It appears obvious that the glucose-insulin tolerance test will detect many more latent diabetics. The oral glucose tolerance test is no longer useful in hypoglycemia diagnosis because experts say the test can actually trigger hypoglycemic symptoms. The conclusion that current screening recommendations are not consistent with available evidence was briefly reviewed. William Hudspeth, associate professor of psychiatry form the University of Nevada School of Medicine, it is pointed out that frequently hypoglycemic symptoms do not correlate with the low point on a glucose tolerance test. What seemed to correlate better with hypoglycemic symptomatology was either low or normal glucose in combination with a distinct insulin peak. It is pointed out that they also may have occurred despite a fairly normal looking glucose tolerance test. It shows the higher sensitivity of IGT over IFG for predicting progression to type2 diabetes.
For this reason, the new Kraft Prediabetes Profile should not only yield more information as outlined below with regard to the diagnosis of diabetes mellitus and latent glucose tolerance tests, but it also should enable us to do more for hypoglycemia. Screening by the criteria for IFG alone would identify fewer people who subsequently, progress to type2 diabetes than would be the oral glucose tolerance test.
Of the 3,650 glucose tolerance tests, 1,713 were defined a normal (for diabetes mellitus) according to the criteria of the American Diabetes Association. Hudspeth’s group has evaluated this phenomenon further by running insulin tolerance along with glucose tolerance and at the same time putting an EEG on each patient and observing for brain wave response.
