Size and location in the body
The kidneys are bean-shaped and the size of your fist. They lie in the middle of the back, on each side of the spine.
Normally, there are two kidneys in our bodies. Among other things, they are responsible for the water balance and the filtering of toxins.
Function of the kidneys
Did you already know?
Your kidneys work 24 hours per day
All of the blood is filtered about 300 times throughout the day if the kidneys are healthy
On average, around 1,500 liters of blood flow through the kidneys a day

Symptoms of kidney disease
You should be aware that the warning signs and symptoms of chronic kidney disease are often ambiguous. Many patients have chronic kidney disease without knowing it. In general: Only a physician can make a clear diagnosis! Don’t diagnose yourself.
- Reduced urinary excretion
- Water retention in hands, face and legs
- Shortness of breath
- Disordered sleep
- Loss of appetite, nausea/ vomiting
- High blood pressure

Trust your physician and consult her or him if you are not feeling well. The sooner you speak to your physician and the more open you are about your symptoms, the better your physician can react and find a suitable treatment for you. The right measures at the right time can have a decisive influence on the course of kidney disease. Unfortunately, existing chronic damage to the kidneys cannot be reversed. If complete kidney failure has occurred, the function of the kidney must be replaced. There are various options for this.
