Drinking more water and urinating is not a bad kidney, it is a normal physiological phenomenon. There is a regulatory mechanism in our body to maintain the balance of water, this regulatory mechanism is to drink too much water, the water excreted from the kidneys will also increase, is often said to increase urine, is to maintain the water balance, to prevent the accumulation of excess water in the body. If too much water accumulates in the body, it will cause edema and elevated blood pressure in milder patients, and heart failure and cerebral edema in more serious patients, leading to very serious consequences. A typical example is chronic renal failure uremic patients, this period of patients have lost the ability to regulate the drainage of the kidneys, in the case of drinking more water discharged urine is not a lot, too much water in the body accumulation, will cause the above-mentioned complications. Therefore, drinking water and urinating a lot is a normal physiological phenomenon, not a bad kidney; on the contrary, if you don’t drink much water, but still urinate a lot, especially at night, this situation is a sign of bad kidney, which usually indicates a decrease in renal tubular concentration function.
