Q: What is the normal size of a kidney? I am a 42 years old man undergoing dialysis twice a week for 4 hours. I am also having diabetes from the past year and take Amlodac 10 mg and Minipress. Can I do yoga and walking? Please advise.

A:Kidney size is usually about 10 cm in length. Kidney size does not reflect function of the kidney. A normal size kidney may have poor function and a small sized kidney may have normal function. You can do yoga and walking.
