Dizziness is not caused by elevation of blood glucose(hyperglycemia). Bring him to see an ENT doctor to r/o inner ear disorder.

Usually dizziness occurs with a low sugar. A high sugar can cause dizziness if person becomes dehydrated and has a low bp. 'reactive' hypoglycemia can follow a large sugar/ carb load which may trigger the over secretion of Insulin and a precipitous drop in blood glucose. This phenomenon can be detected by using a glucose monitoring device before/after the carb load.
