Drinking water for a while to urinate may be caused by excessive water intake, but also may be caused by urinary tract infection, renal tubular acidosis and other diseases. 1. Excessive water intake: If you drink too much water, it may cause the body’s water storage to exceed the body’s demand, which will lead to excess water being discharged from the body by way of urine. 2. Urinary tract infection: the cause of urinary tract infection is mainly related to infectious factors, prostate hyperplasia, low immunity, renal dysplasia and other reasons may also induce the disease. Patients will have symptoms such as urinary urgency, painful and frequent urination, which may also be accompanied by difficulty in urination, headache and other phenomena. 3. Renal tubular acidosis: Renal tubular acidosis may be related to congenital functional defects, drugs and other factors. Patients mainly show symptoms such as easy thirst, drinking and urinating. If you need to urinate after drinking water for a while, it is recommended to go to the regular hospital for examination and clarification of the cause of the disease after eliminating the factor of excessive water intake.
