What are the symptoms of a bad kidney?
Kidney problems often present subtly at first, making early detection crucial. Symptoms can vary depending on the severity and underlying cause, ranging from mild to severe. Some common signs include:
- Changes in urination: This could involve urinating more frequently, especially at night (nocturia), or less frequently than usual. The urine may also appear foamy (due to excess protein) or contain blood. [Source: National Kidney Foundation, Mayo Clinic]
- Fatigue and weakness: Persistent tiredness despite adequate rest is a common early sign. [Source: Mayo Clinic, NHS]
- Poor appetite: A loss of interest in food and unintentional weight loss can indicate kidney problems. [Source: NHS, Mayo Clinic]
- Persistent puffiness: Swelling, particularly around the eyes and ankles (edema), results from fluid retention. [Source: National Kidney Foundation, Mayo Clinic]

It's important to note that these symptoms can also be caused by other medical conditions. Therefore, it's essential to consult a doctor for proper diagnosis and treatment if you experience any of these signs. Early detection and management are key to slowing kidney disease progression and preventing complications.
