Can high blood sugar levels lead to type 2 diabetes?

Yes: Extended exposure to elevated blood sugars can desensitize Insulin receptors in your body, leading to difficulty in blood sugar crossing from the blood stream into the cell. The cells then sense that blood sugars are low inside the cell, thus causing the pancreas to increase Insulin levels to normalize the sugar inside the cell. Over years, this high Insulin state leads to type 2 diabetes.

Type 2 diabetes: High blood sugar levels are the definition of diabetes. Be it type 1 or type 2 diabetes, the result is an inability of the body to regulate blood sugar levels which results in hyperglycemia. Having high blood sugar does not cause diabetes.

Yes: Yes, type 2 diabetes can be "clinically silent, " meaning you may not have any symptoms at all. The only sign that you have it may be the high blood sugar levels. This is very common! it is very important to treat the diabetes now, early on, before any symptoms or complications develop.

Type 2 diabetes: Take your medication as prescribed. Check your blood sugar just before breakfast and just before lunch. Document your food intake and your two blood sugar levels. If the levels are close to each but both are high you can either take more pre-breakfast medication and/or change your eating habits. Once this is controlled do the same for breakfast and dinner.

Yes : If you are running consistently high blood sugars (>100-110), then you are at the very least on the verge of diabetes. High sugars are caused by either not enough Insulin (type 1 diabetes) or not being able to properly use Insulin (type 2 diabetes).
