Whether drinking more water will hurt the kidneys needs to be judged according to whether there is kidney disease. If the patient’s cardiac and renal function is normal, drinking more water usually has no damage to the kidneys, but it is recommended that the daily water intake of 1,500 to 2,000 ml is more appropriate; if the patient has abnormal kidney function, drinking more water may increase the burden on the kidneys, thus damaging the kidneys.
The main functions of the kidneys are to generate and excrete urine, eliminate excess water and metabolic waste, regulate the homeostasis of the body’s internal environment, maintain electrolyte and acid-base balance. For normal people, drinking a lot of water basically has no effect on the kidneys, but it is recommended that patients drink a moderate amount of water every day, 1500~2000ml is more appropriate, which helps the body to discharge metabolic waste.
If patients with impaired renal function, glomerular filtration function decline, drink too much water, water can not be discharged from the body in a timely manner, the accumulation of water in the body can appear edema, hypertension, etc., thus increasing the burden on the kidneys, and sometimes even affect the heart function, and then damage to the kidneys.
It is recommended to drink a moderate amount of water, and if there are patients with abnormal kidney function, it is recommended to go to regular hospitals in a timely manner, under the guidance of the doctor for targeted treatment or therapy.
