Kidney failure can develop gradually, often showing subtle symptoms in its early stages. Common warning signs include fatigue, swelling in the ankles or feet, difficulty concentrating, and reduced urine output. Patients may also notice shortness of breath, persistent nausea, and changes in urine color or frequency. Muscle cramps, high blood pressure, and poor appetite are additional signs to watch for. Early detection is critical to prevent further damage. If you experience any of these symptoms, consult a healthcare provider immediately. Recognizing the warning signs of kidney failure can help in timely diagnosis and better management of the condition.
