I'm not embarrassed but I know that there are plenty of people who are in denial that they have diabetes. When I was first diagnosed - no, wait a minute, I wasn't "diagnosed" as a diabetic. I was prescribed a blood sugar meter because my blood sugar levels were elevated, which is how my doctor put it. So, what I understood in the beginning about
5 years ago was that my blood sugar was higher than normal and I might
become a diabetic. All this wishy-washy jumble of terms was confusing and probably still is. I cannot metabolize carbohydrates normally. If I don't cut down on carbs and if I don't get regular, sustained exercise, I cannot control my blood sugar. I still produce insulin but I'm insulin resistant. I'm not on meds. I consider myself
diabetic. I think it's an injustice to say that those with insulin resistance are not diabetic and this avoidance of labeling only adds to the confusion. How many people have said "I'm not diabetic. I just have high blood sugar sometimes and the doctor said to watch my diet"? That's denial and because most doctors are reluctant to say a patient is an outright diabetic if he/she can bring the blood sugar down by losing weight, reducing carbs and exercising and thus avoiding meds, the patient doesn't believe it's really diabetes.
Of course, maybe the experience is different for type 1s. There is no denying that a type 1 must have insulin as the close supervision of blood sugar is so very important. And as MsOuchie said, there are extended reasons a person may be reluctant to state he is a diabetic. So, it's complicated. Sorry for the long-winded answer!
