There are two different tests your doctor can use to measure your blood glucose to determine if you have pre-diabetes or diabetes: the fasting plasma glucose test (FPG) or the oral glucose tolerance test (OGTT). The FPG test is a blood test that determines the amount of glucose (sugar) in the blood after an overnight fast (not eating for at least 8 hours). With the OGTT test, a person's blood glucose level is measured after fasting and then 2 hours after drinking a glucose-rich beverage. See the chart below for the ranges of blood sugar levels and how they are used to diagnose pre-diabetes and diabetes.
I’ve read in dozens of articles across the internet that reactive hypoglycemia is one of the first signs of diabetes. In other words, if you have true reactive hypoglycemia (with symptoms appearing at 2-3 hours), the statistics say you are more likely to have a lower risk of diabetes.
In order to illustrate why it isn’t easy to give a diagnosis for any particular disease, here is a graph of two patients who have just had a Glucose Tolerance Test (GTT).
Blood glucose levels alone tell you practically nothing about your possible prediabetic status! It’s very interesting because it explains how doctors and diabetic associations have it all wrong about diabetes risk. There are economical interests as to why the Diabetic Association don’t change their criteria for diabetes diagnosis and risk.
Considering this data it seems that many people with Reactive Hypoglycemia are indeed at risk for diabetes, because they have an impaired glucose tolerance. If you are just discovering your RH – please understand that it takes time for the carbo-cravings to subside. I have not found a reason to avoid meat, but do best when I also include a sizable amount of vegetables. The first consideration is to rule out a fasting hypoglycemia, especially when hypoglycemic symptoms occur several hours after food intake. Unfortunately, diagnosis has not been as simple as the classic OGTT findings just mentioned would imply. In summary, the diagnosis of postprandial hypoglycemia is clouded by controversy, especially the category of functional hypoglycemia.
Various factors can affect blood glucose levels.Some of them you can take full control, such as if you want to be healthier and beat diabetes. Yes, really if you watch what you eat, if you eliminate your bad habits such as carouse, smoking, check you weight, do not became overweight, and are regularly exercised,and not being sedentary, you easily can keep in good range blood sugar level.

The OGTT is a two-hour test that checks your blood glucose levels before and 2 hours after you drink a special sweet drink.
Before people develop type 2 diabetes, they almost always have "prediabetes" — blood glucose levels that are higher than normal but not yet high enough to be diagnosed as diabetes.
Doctors sometimes refer to prediabetes as impaired glucose tolerance (IGT) or impaired fasting glucose (IFG), depending on what test was used when it was detected. Some people with prediabetes may have some of the symptoms of diabetes or even problems from diabetes already. Patient Education Materials — All About PrediabetesThis two-page introduction to prediabetes is in PDF format so you can download it, print it, and hand it out to patients.
In general, it is recommended that any blood test that is outside the normal range be repeated on a different day to confirm the diagnosis. As a mathematician who teaches statistics classes at the college level, I have a pretty good idea. The patient with the red line is overweight (with most of her fat around the hips and thighs). A Hyperglucidic Breakfast Test is the only test that will be able to tell you if you have a high sensitivity to insulin (and therefore a lower statistical risk of diabetes) or a low sensitivity to insulin (and an increased statistical risk for diabetes).
It seems that a high fasting blood glucose is not even necessary to be diabetic and that it is the worse predictor of diabetes.

Reactive Hypoglycemia when connected with diabetes can be understood as resistant phase 1 insulin but excessive phase 2 insulin, whereas diabetes is resistant phase 1 insulin but unadequate phase 2 insulin. Sitting on the couch, eating that litre of Oreo Cookie ice cream (yes, I remember the carbo-munchies!) will lead you to diabetes just as fast as the non-RH crowd. I do better with rice, but even after 20 years I only consume a few tablespoonfuls with my meal. Postprandial Hypoglycemia of gastrointestinal tract origin (sometimes called the “dumping syndrome”) most often occurs after gastric surgery and results from unusually swift or complete gastric emptying of ingested carbohydrate into the duodenum, resulting in abnormally high blood glucose levels and temporary hypoglycemia after hastily produced insulin has overcome the initial hyperglycemia. Some persons with subclinical or early diabetes mellitus of the NDDG type II (noninsulin-dependent) category may develop mild and transitory hypoglycemia 3-5 hours after eating. A few patients with insulinoma or alcoholism may develop postprandial hypoglycemia, although fasting hypoglycemia is much more common. Self-administered hypoglycemic agents are also possible, although for some reason this is not often mentioned when associated with postprandial symptoms. Many investigators have found disturbing variability in OGTT curves, which often change when testing is repeated over a period of time and may change when testing is repeated on a day-to-day basis. This is a test that you can manage to do anytime you want during day.2- Fasting blood sugar level test.

If your doctor determines that your blood glucose level is very high, or if you have classic symptoms of high blood glucose in addition to one positive test, your doctor may not require a second test to diagnose diabetes. The advantages of being diagnosed this way are that you don't have to fast or drink anything. Fasting means after not having anything to eat or drink (except water) for at least 8 hours before the test. This condition puts you at a higher risk for developing type 2 diabetes and cardiovascular disease. For some people with prediabetes, early treatment can actually return blood glucose levels to the normal range. The American Diabetes Association recommends the FPG because it is easier, faster, and less expensive to perform.
According to many prominent researchers (including Achim Starke, MD and Jean-Frederic Brun), it does not. Giving a patient a diagnosis of reactive hypoglycemia (or prediabetes) involves looking at a few numbers, analyzing those numbers, and coming up with a diagnosis for the patient. Another 20% said she had a 1% chance, and an incredible 60% got it wrong and said she had an 81 or 90 percent chance of having cancer!
The red patient looks borderline, but the GTT cannot be used to accurately diagnose reactive hypoglycemia (to find out why, see my article on tests for reactive hypoglycemia).
It seems that fasting blood glucose as low as 95 are already sign of impaired glucose metabolism. There are many diabetics in my family and none of them have diabetes markers: they are all thin, with no large waist and with low blood pressure. However there’s other literature that suggests such a low score would indicate further testing to find out the cause. It took me a good 12-18 months for the cravings to fully subside, but eating a diet containing a balance of protein (I am not vegetarian), fat, and (after a couple of months) very complex carbohydrates worked for me. This seems to be an early manifestation of their disease, which often disappears as the disease progresses.
The best test would be a blood glucose measurement drawn at the same time that symptoms were present.
In some cases this is related to factors known to influence the OGTT, such as inadequate carbohydrate preparation, but in other cases there is no obvious cause for OGTT discrepancies. Your gift today will help us get closer to curing diabetes and better treatments for those living with diabetes. Unfortunately, physicians frequently misread health statistics, and do not know the probability that someone has a particular disease given the results from a screening test. Additionally, the red patient has excess body fat around her hips, which actually protects from diabetes!
It seems that a reading above 145 at any moment in the glucose tolerance test is the best predictor of diabetes.

My understanding was that RH+weight gain put more of a strain on the pancreas, resulting in a higher chance of diabetes. Diabetics have to know accurate measurements on their blood sugar levels or risk having to high blood sugar and damage their body. Making knowing what is the normal blood sugar level and absolute need for the survival of the diabetic.
This is a small unit that measures the amount of glucose in a person’s blood and displays it.
In some cases symptoms can be correlated with acceptably low blood glucose values, in which case many physicians make a diagnosis of functional hypoglycemia (although there is controversy on this point, to be discussed later with the 5-hour OGTT).
Because symptoms in daily life usually occur at times when blood specimens cannot be obtained, the traditional laboratory procedure in postprandial hypoglycemia has been the 5-hour OGTT.
Another major problem is disagreement regarding what postprandial blood glucose value to accept as indicative of hypoglycemia. That’s according to a report by the journal Psychological Science in the Public Interest published in US News. The blood is placed in a small plastic strip that is then scanned and the results are displayed on a small window on the side. However, because of the large number of diabetic persons, it may be a relatively frequent cause of postprandial hypoglycemia. In other cases, probably the majority, symptoms cannot be adequately correlated with acceptably low blood glucose values. In alimentary hypoglycemia the classic OGTT pattern is a peak value within 1 hour that is above OGTT reference limits, followed by a swift fall to hypoglycemic levels (usually between 1 and 3 hours after glucose). Insulin is a chemical created by the pancreas; the job that does is in turning the glucose (sugar) in the body into fuel that the body can use.
Initial elevation of blood glucose values may or may not be higher than in normal persons, but the 2-hour postprandial value is elevated.
Either the OGTT serum glucose value is low but no symptoms occur, or (less commonly) symptoms occur at a relatively normal glucose level.
In diabetic hypoglycemia, there is an elevated 2-hour postprandial value, followed by hypoglycemia during the 3-5 hours postglucose time interval. Things that can be done to help lower the blood sugar levels include a normal blood sugar level chart this is where you write down all of your readings that you take and what you were doing prior to it to narrow down activities that should not be a part of your daily life. The rise in plasma insulin after eating tends to be delayed, and the insulin peak (when finally achieved) may be somewhat elevated, resulting in the hypoglycemic episode. In functional hypoglycemia, there is a normal OGTT peak and 2-hour level, followed by hypoglycemia during the 2 to 4-hour postglucose time interval (Fig.). In some cases it is not clear whether serum or whole blood was assayed (reference values for whole blood are 15% less than those for serum or plasma). An additional problem involves the concept of chemical hypoglycemia versus clinical hypoglycemia.
A number of studies have shown that a certain percentage of clinically normal persons may have OGTT curves compatible with functional hypoglycemia without developing any symptoms. Moreover, in some studies continuous blood glucose monitoring systems disclosed hypoglycemic dips not evident in standard OGTT specimens. On the other hand, some persons with symptoms compatible with hypoglycemia do not develop OGTT values below reference limits. To make matters more confusing, some studies have found that when the 5-hour OGTT was repeated after it had initially displayed a hypoglycemic dip, a substantial number of the repeat OGTT results became normal (about 65% of cases in one report). Finally, several studies have indicated that hypoglycemic values found during an OGTT usually disappear when an ordinary meal is substituted for the carbohydrate dose. Since actual patients do not usually ingest pure carbohydrate meals, this casts doubt on the reliability and usefulness of the OGTT in the diagnosis of functional hypoglycemia.
