What are the early symptoms of chronic kidney failure?

In the early stages of chronic kidney failure, symptoms often manifest as gastrointestinal discomfort, such as nausea, vomiting, abdominal bloating, and loss of appetite. These occur because impaired kidney function prevents effective elimination of metabolic waste from the body, thereby affecting normal gastrointestinal function. Patients may also experience general fatigue, soreness and discomfort in the lower back, and even neurological symptoms such as lethargy and decreased memory. All these signs serve as important early warnings of chronic kidney failure. Patients should actively treat underlying conditions such as diabetes, kidney disease, and hypertension to slow disease progression. Additionally, proper dietary adjustments are essential, including a low-protein, low-phosphorus diet, which helps reduce the burden on the kidneys. Furthermore, patients should control high blood pressure, avoid nephrotoxic medications, maintain healthy lifestyle habits and a positive mindset, and actively cooperate with their physician's treatment plan.
