#1. Need to urinate more frequently – loss of kidney function can increase the urge to urinate, especially at night (nocturia). In men it can be also be a sign of prostate enlargement.
#2. Lack of energy – as toxins build up in your body, you may feel inexplicable long-term fatigue, which doesn’t go away after rest and sleep.
Your kidneys also produce a specific hormone erythropoietin, which plays a key role in red blood cell creation. If your kidneys lose the ability to function properly, you may experience a lack of red blood cells and hemoglobin (anemia). This can be the second reason for chronic tiredness and weakness.
#3. Eye puffiness – fluid retention is one of the most frequent signs of renal dysfunction. The problem is linked with increased protein excretion through urine. As a result, excessive liquid stores up inside your body, causing puffiness around the eyes.
#4. Muscle cramping – your failed kidneys can cause an electrolyte imbalance. Abnormal levels of calcium and phosphorus in your body can result in muscle spasms.
#5. High blood pressure – we’ve said that hypertension can lead to kidney damage but the problem can develop backwards, meaning that high blood pressure may be a result of kidney dysfunction.
