Answer
Vishal:

The whole concept of fermentation is the utilization of sugars in whatever form by the yeast to produce CO2 and alcohol.  The yeast metabolize all the sugars in the ferment except carmelized sugars.  A beer or spirit should not be sweet except for sugars added after the spirit is distilled, or in the case of beer, those sugars that might be carmelized during the boil of the beer before fermentation.  If a beer does not fully attenuate, that is fully ferment due to the yeast secumbing to alcohol toxicity before it can comsume all the sugars it will be sweet, but his is a fault in the beer and not to be expected in a properly fermented beer.

So to answer your question directly, there is very little sugar.  If on the other hand, you are asking about the carbohydrates in beer that might raise your blood sugar,the carbs are considerable since alcohol is a carbohydrate.
