Q:
Can high levels of B and C vitamins increase blood sugar levels in Type 2 diabetes.

A:
Vitamins typically do not cause blood glucose elevations. High levels of C can mask the results of a glucose tolerance test. Some people report feelings of increased appetite or staying awake at night after a B-complex tab. B vitamins are directly involved in metabolic activities, so increased energy can be a result. It is generally the macronutrients of carbs, proteins and fats that raise blood sugars. I suggest you thoroughly scrutinize your intake to see where the rise may be coming from. You can do this both with and without the vitamins to see if you note a difference.
