Drinking more water and urinating more is completely normal, indicating that the urinary system is functioning normally, the kidneys are functioning well and the urinary tract is open. The urinary system includes the kidneys, ureter, bladder and urethra. If you drink more water, the body’s blood volume will increase, and the urine produced by the filtration of blood through the kidneys will increase, and the urine will be discharged through the ureter, bladder and urethra will naturally increase. If you drink a lot of water, but not much or less urine, unless you sweat more in summer, urination can be reduced, otherwise it is possible that kidney insufficiency causes urine reduction or there is an obstruction in one part of the ureter, bladder and urethra, and patients discharge less urine out of the body, which can cause edema, electrolyte disorders, water and sodium retention and other uncomfortable symptoms, which can be life-threatening in serious cases.
