Kidney disease can affect your body’s ability to clean your blood, filter extra water out of your blood, and help control your blood pressure.
You’re born with two kidneys. They’re on either side of your spine, just above your waist.
When your kidneys are damaged, waste products and fluid can build up in your body. That can cause swelling in your ankles, vomiting, weakness, poor sleep, and shortness of breath. Without treatment, the damage can get worse, and your kidneys may eventually stop working. That’s serious, and it can be life-threatening.
