Question : Hi,

Since last few months I have started feeling thirsty and frequently urinating. Initially I thought it might be due to high sugar, so I got my blood sugar tests done and found that the Fasting Sugar Level was 92 and Post Meal Sugar level was 89.
Please suggest what could be other possible reasons for frequently urinating and feeling thirsty and what other test should I get done to reach to a conclusion.
Will appreciate a quick response.

Thanks,
xxxxxxxxxxxxxxxxx
