DIABETES, PRÉ-DIABETES OU EXAME NORMAL: como saber?

And the diagnosis? How is diabetes diagnosed? Is there such a thing as pre-diabetes? How do I know if I have pre-diabetes, if I have diabetes, or if everything is normal? Do you also have these questions? Every day I receive several people who ask me: Doctor, do I actually have diabetes? That's what I'm going to talk about today: how do you know if you have diabetes? I'm Carlo Cunha, I'm a family doctor, and this is my health tip for today. To know if you have diabetes, you will have to take a test. Because the criterion that defines whether a person has diabetes or not is entirely laboratory-based. What defines this is the blood glucose level. And the main test to be done is the 8-hour fasting blood glucose test. To know if you have diabetes, you will need to do the 8-hour fasting blood glucose test – that's 8 hours of fasting; and the test value must be equal to or greater than 126 mg/dL. It is recommended that this test be confirmed. What do I mean by that? The most current recommendation for diagnosing diabetes is that a person has at least two fasting blood glucose levels equal to or above 126 mg/dL. This is important because a diabetes diagnosis is something you carry for the rest of your life. Once it's defined that you have diabetes, you will always have diabetes. We can control blood glucose, which is the goal and what we want for all people with diabetes. But a person with controlled glucose, once it has been defined at some point in their life that they have diabetes, that person will continue to have diabetes, but controlled diabetes. That's why it's important to have at least two tests to confirm the diagnosis. You might be wondering: "Okay doctor, but what about that glucose tolerance test? The one where they collect your fasting blood glucose, give you a sweet liquid to drink, and two hours later collect your blood glucose again? Can the diagnosis also be made with this test?" Yes; that's the 75g Glucose Tolerance Test. This test also diagnoses diabetes. In this case, the person fasts for 8 hours, the laboratory collects their fasting blood glucose; the person receives a liquid with 75g of glucose to drink, remains at the laboratory resting, seated (they can't go out to run errands and return two hours later); and then two hours later, a new blood glucose test is performed. If this second test gives a result equal to or greater than 200, it also confirms the diagnosis of diabetes. And just to finish, so nobody can say I didn't mention it, there's a third criterion considered for the diagnosis of diabetes: having a blood glucose level equal to or greater than 200 at any time of day. In this case, it's a... Blood glucose measured at any time, regardless of fasting or recent meals. A reading above 200 is also a criterion that confirms the diagnosis. But pay close attention, I said blood glucose – that is, the glucose measured in blood collected from a vein; a laboratory test. The blood glucose test, also called HGT, the finger-prick test, is not used for diagnosis. Now, two things to finish up: first, what are the warning signs of diabetes? In general, and most commonly, a person often doesn't show a typical symptom of diabetes from the beginning of the disease. Often, when these symptoms I'm going to talk about appear, the person has already had the disease for some time. But it's important to be aware of the 4 "Ps" of diabetes: unintentional weight loss (which is losing weight abruptly and without dieting or other methods); the second P is polyuria (an increase in urinary frequency, the person urinates more and more often throughout the day); another "P" - polydipsia - excessive thirst, drinks more fluids, water, in short, is thirstier; and the fourth "P" - polyphagia - the person eats more, but even eating more and being hungrier can lose weight. And the second thing I wanted to tell you now to finish this video is that there is an intermediate zone, it's halfway between a definitive diagnosis of diabetes and completely normal blood glucose levels. It's a zone that some call pre-diabetes or glucose intolerance. This happens when that 8-hour fasting blood glucose level we talked about at the beginning of this video is between 100 and 125. It's a warning zone. But it's also a very important zone to work on prevention, to improve lifestyle habits to prevent this pre-diabetes from developing into diabetes over time. So, if you are in this range, focus on prevention and you can avoid diabetes.
