Frequent urination in night. The reason?

Sir, Many a times i experience frequent urination in night. Actually i drink lot of water before bed. This could be the reason? Daytime urine frequency is normal. I also got my urine analysis n blood sugar test done yesterday. Reports attached herewith. In May I also got my insulin sensitivity test or HOMA IR test done and it was normal with the values below:- Fasting Blood sugar - 89, Insulin (fasting)- 4.2 uU/mL Homa IR Index:- 0.55 HBA1C - 5.37% . Earlier about 5 months ago i also got my kidney function test done and all the parameters like createnine, blood urea, electrolytes etc were normal. My weight also normal at 72 with 5.8 ft height. I have 2 doubts:- 1. I have noticed that on those days when I didn't properly pass my stoles in the morning then i feel the urge to go to bathroom multiple times in the night. Could this be the reason? 2. even all blood sugar reports being normal I always have doubt that can diabetes be the reason for the same. Please clear these two doubts.
