3. Kidney Failure
A severe cause of restless leg syndrome is kidney failure. The kidneys are a vital organ of the body. The main function of this organ is to detoxify the body. The kidneys also help maintain the acid-base balance in the blood. If the kidneys are not functioning properly, or they start to fail, harmful chemicals will not be excreted from your body. These chemicals will then accumulate in the blood as well as your other organs.
When this happens, a person who is suffering from kidney disease may also experience the symptoms of restless leg syndrome. Kidney failure may result from several health issues. Both high blood pressure and diabetes are both at the top of the list when it comes to possible kidney failure. If you suffer from a kidney condition and you start to experience restless legs, it is important to see your doctor right away.
