Sir, My Age Is 51 Years. Though I Have No

Sir, my age is 51 years. Though I have no symptioms of suger at all, but for last few days my urine attracts ants. Is it a symptiom of suger or not. I have got checked my suger level last year during Jan 2014. The report was excellent. I used to walk 10 KM daily (4 KM morning+4 KM evening+2 KM after dinner). Kindly intimate me whether the above symptioms are for suger or not.
