1. Unexplained Fatigue
Fatigue linked to kidney failure is often caused by anemia, a condition where the kidneys fail to produce enough erythropoietin, a hormone essential for red blood cell production. This results in reduced oxygen delivery to tissues, leaving you feeling persistently tired despite adequate rest.
Unlike typical tiredness from lack of sleep or stress, this fatigue doesn’t improve with rest and can interfere with daily activities. If you notice a steady decline in your energy levels without an obvious cause, it’s important to discuss this with your healthcare provider. Blood tests measuring hemoglobin and kidney function are essential to identify this condition early.
2. Swelling in Extremities
Swelling, or edema, in the feet, ankles, hands, or around the eyes is a common early sign of kidney dysfunction. When kidneys fail to remove excess sodium and fluid, the body retains water, leading to puffiness and swelling. This fluid build-up may worsen as the day progresses or after consuming salty foods.
Persistent edema should never be ignored, especially if accompanied by other symptoms such as fatigue or changes in urination. Early intervention with diuretics or dietary sodium restriction can prevent progression. A thorough evaluation including urine tests for proteinuria and blood work is necessary to assess kidney health.
