Hi If you drink more water..the urination will be more..thats normal but if you are doing excessive urination, getting more thirsty and you have to wake up at night for emptying your bladder..i would suggest you to check your blood sugar levels. Young age diabetes are on the rise. Also do a urine routine and microscopic analysis.Regarding urinary bladder issues..let me tell you that if your blood sugar levels are norrmal and urine RE/ME reports are normal..then need to evaluate your bladder further. Do you have any pain? Do you have a burning sensation during urination? Plz give a family history of diabetes if any...
