Get StartedWhen to seek medical advice
By Mayo Clinic staffIf you have a chronic medical condition that puts you at increased risk of chronic kidney failure, your doctor is likely to monitor your blood pressure and kidney function with urine and blood tests during regularly scheduled office visits.
Call your doctor if you experience any of the signs and symptoms of chronic kidney failure between visits. These may include a change in urination patterns or quantity, dark or cola-colored urine, unexplained weight loss, nausea or vomiting, fatigue, headaches, or a yellowish-brown cast to your skin. Even if you have no risk factors for kidney failure, see your doctor immediately if you notice that you're urinating much more or much less than usual or if you see any blood in your urine.
