Kidney failure is often associated with two typical signs: back pain and frequent urination. However, chronic kidney failure sometimes has other subtle signs that patients may not recognize. Early detection helps patients seek timely medical attention and treatment, preventing dangerous complications.
Extreme fatigue and weakness. The kidneys produce erythropoietin (EPO), a hormone that helps the body make red blood cells. Kidney failure reduces EPO production, making the body rely more on existing red blood cells to deliver oxygen to muscles and the brain. A decrease in red blood cells lowers oxygen levels in the body, causing excessive fatigue and weakness, even after adequate rest.
This fatigue differs from normal tiredness because it persists for extended periods. Reduced energy levels make daily activities more difficult and can lead to excessive daytime sleepiness. Anemia in kidney failure patients can also contribute to prolonged fatigue.
Swelling in the hands, feet, or around the eyes. Healthy kidneys remove excess salt and water from the body. Kidney failure impairs this fluid balance, leading to swelling in various parts of the body, such as the feet, around the eyes, and fingers. This swelling can make rings feel tight or shoes difficult to wear and may worsen over time.
Changes in appetite and taste. People with kidney failure often report a salty, bitter, or metallic taste in their mouths. Decreased appetite can lead to gradual weakening over time. Kidney failure patients often experience loss of appetite due to toxins disrupting the digestive system and interrupting signals to the brain. Early detection of this sign is crucial, as proper nutrition aids recovery.
Difficulty concentrating or memory problems. In kidney failure patients, blood isn't filtered properly, increasing the risk of waste and toxin buildup. These toxins can interfere with brain function, leading to poor concentration and memory loss. The brain is also affected by reduced oxygen supply and the increase in harmful waste products affecting the nervous system. Individuals with kidney failure often struggle to focus or remember information accurately.
Persistent itching without a rash. Itchy skin due to kidney failure typically doesn't present with a rash or visible reaction. Impaired kidney function prevents proper waste removal, causing toxins to accumulate and irritate the skin beneath the surface. This symptom causes discomfort and disrupts sleep. Because skin irritation from kidney failure differs from typical allergic reactions, seeking medical advice is recommended.
