Doctor's answer (1)
Dr. Yang Ziqi
Whether drinking a lot of water harms the kidneys depends on the specific situation:
1. **For individuals with normal kidney function**: Drinking more water can promote the excretion of metabolic waste and help maintain water balance in the body, which is beneficial to health. It is generally recommended that adults consume about 1.5 to 2 liters of water per day, an amount that will not harm the kidneys.
2. **For individuals with impaired kidney function**: Such as those with kidney insufficiency or kidney disease, whose kidneys have a reduced ability to excrete water. Excessive water intake may lead to fluid accumulation in the body, potentially causing edema and even placing a burden on the cardiovascular system, which could result in serious consequences such as heart failure or respiratory failure. Therefore, these individuals should control their water intake under a doctor's guidance.
