Most people have two kidneys. They usually lie on each side of the body, under the lower ribs. Their job is to filter the blood, removing waste products and excess water which they make into urine. The urine from each kidney drains down a tube (the ureters) into the bladder.
The kidneys are essential for healthy life. If the kidneys stop working, the build up of waste products and fluid can make people very unwell indeed. Fortunately, most kidney problems can be detected and treated before there is any permanent damage.
Symptoms of kidney problems include:
- Pain in the kidney area (loins)
- Blood in the urine
- Feeling unwell, sickness or vomiting
