Is drinking a lot of water good for your kidneys?

Why would Bun be high?

A high BUN value can mean kidney injury or disease is present. Kidney damage can be caused by diabetes or high blood pressure that directly affects the kidneys. High BUN levels can also be caused by low blood flow to the kidneys caused by dehydration or heart failure. Many medicines may cause a high BUN.

What BUN level indicates dehydration?

Can dehydration cause abnormal kidney function tests?

Both tests measure the amount of waste product in the blood; higher volumes of BUN and creatinine indicate that the kidneys are not working properly. Dehydration is known to reduce blood flow to the kidneys and elevate creatinine and BUN levels in the blood.

Should I worry if my GFR is 56?

A GFR of 60 or higher is in the normal range. A GFR below 60 may mean kidney disease. A GFR of 15 or lower may mean kidney failure.
