Dr. Kumar says that drinking less water has a negative effect on the kidneys in many ways. First of all, urine becomes thick due to a lack of water, which greatly increases the risk of kidney stones.

People who have only one kidney often have this question in their mind that how much water should they drink. Generally, a healthy person is advised to drink 2 to 2.5 liters of water a day. However, the amount of water may be slightly different for people who have one kidney. According to Dr. A. Kishore Kumar, a renowned nephrologist of Telangana, a person with one kidney should drink water according to his physical needs, but this amount should not be less than two liters.
Lack of water has this effect on the kidney
Dr. Kumar says that drinking less water has a bad effect on the kidney in many ways. First of all, due to lack of water, the urine becomes thick, which greatly increases the risk of kidney stones. Apart from this, when there is a lack of water in the body, bacteria get a chance to grow, which can lead to kidney infection and in severe cases, kidney failure.
It is important to drink adequate amounts of water daily
The kidneys have to work harder to filter blood, which affects their efficiency. Without getting enough water, toxins cannot be removed from the body and toxins start accumulating in the kidneys, which is extremely harmful for kidney health. Lastly, drinking less water can slow down metabolism, which also increases the risk of obesity. Therefore, it is very important to drink enough water daily to keep the kidneys healthy.
How much water should a person with one kidney drink?
People who have only one kidney should drink at least 2.5 liters of water to keep the body hydrated. However, the right amount of water varies from person to person and also depends on the stage of chronic kidney disease. Therefore, it is best to decide the amount of water you should drink after consulting your doctor.
How much water should one drink?
According to Dr. Kumar, a healthy person should drink 3 to 4 liters or at least 8 to 10 glasses of water every day to keep the kidneys healthy. This helps the kidneys dilute the urine and remove harmful toxins from the body. However, if you have any kidney-related disease, such as kidney failure or you are on dialysis, then consume water only on the advice of a doctor. In such a situation, drinking too much water can increase the pressure on the kidneys, which can be harmful.
