If you notice these symptoms, call an emergency doctor immediately!

They no longer completely excrete urea and creatinine, so that the substances are exhaled through the skin. High blood pressure, swollen eyelids, nausea, itchy skin, decreased or increased urine excretion also indicate kidney problems. In this case, have a doctor examine you.
