Dear friend 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.
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
in some conditions there might be transient imbalance of blood sugar due to infections which will become normal after eradication of infection from body.
in case of any known family history of diabetes its worth having a check up
i suggest to check for average blood sugar called
Hba1c andGTT for better analysis of condition.
