Talk to Gastroenterologist on Frequent Urination

Assalamualikum. I have been experiencing this problem for sometime. I feel need to go for urination almost after every hour and before sleeping 3 to 4 times. I checked for my blood sugar level from lab and reports came out to be normal as my blood sugar level was 74. I don't even drink much water and my fluid intake is much less because if i intake more fluid then I'll be needing to go to washroom after every half an hour. Kindly suggest what should i do.
