Dehydration: If you become dehydrated enough the blood flow to the kidneys can decrease and kidney failure can occur. If the kidney failure is bad enough and if one is on certain medications such as potassium, ACE inhibitors, ARBs, spironolactone high potassium can occur. With dehydration the kidneys are not damaged and will recover with hydration.
