Dear sir i can understand your concern
the fasting blood sugar between 100-125 is called as impaired fasting blood sugar.
blood sugar more than or equal to 126 mg/dl is considered as
diabetes.
as you said that you are having belly in my opinion you might be suffering with excess of weight.
This excess of weight can led to a condition called
insulin resistance and can make your blood sugar to go up.
The major symptoms of diabetes are
1.increase frequency of urination
2.increase thirst
3. unexplained weight loss
4.uncontrolled infections and non healing wounds
5.blurred vision
6.too much hunger
most of this symptoms are due to high blood sugars in blood
but in my opinion your blood sugars are only borderline raised so there will not be any symptoms.
reducing weight with exercise will make you normal again
consider visiting doc and doing
GTT test.
