Playing basketball is not a problem for the kidneys if there is no previous kidney disease, normal kidney function and normal urine routine. Playing basketball has little effect on the kidneys, at least it is said to have no bad effect on the kidneys. If you have a previous kidney disease, such as chronic nephritis, or even creatinine urea has begun to rise, there is protein in the urine, basketball strenuous activities are not recommended to continue. Because of the activity, the body’s blood supply is prioritized limbs, muscles, skeletal system, and this time the kidneys will be relatively ischemic state, and the kidneys are very very sensitive to ischemia. That’s why we generally recommend rest for patients with kidney disease, especially in the acute stage, bed rest is recommended, just to increase the blood flow as well as blood supply to the kidney disease, kidneys. So playing basketball, long-distance running, fast running, sprinting, playing soccer and all these strenuous activities are not recommended.
