Hello, and welcome to Healthcare Magic!
I'm not completely sure if you are saying that you have been told in the past you are diabetic, or if you are just concerned that you might be. Let's talk a little about how diabetes
The easiest way to check for diabetes is with a fasting blood glucose
(sugar) level. First thing in the morning, before you eat or drink anything other than water, your blood sugar level should be less than 126. If it is higher than this on two separate occasions, you will be diagnosed with diabetes.
Alternatively, if you are having symptoms of diabetes (frequent urination
, increased thirst, or increased appetite) and your blood sugar is found to be greater than 200, you meet criteria to be diagnosed with diabetes.
The last frequently used way to diagnose diabetes is with a hemoglobin
A1c. A good way to think about this test is that it measures the number of "sugar coated" red blood cells in your body. A value higher than 6.5% on two separate occasions equals a diagnosis of diabetes.
It is also possible to diagnose diabetes using a "glucose tolerance test" but this is done less frequently. None of the blood sugar values you have mentioned would give you a diagnosis of diabetes, but you are certainly pre-diabetic (meaning you are at high risk of developing the disease in the future). This is something you should discuss in detail with your doctor.
I hope I have given you some useful information, and wish you the best of health.
