Patients with chronic kidney failure do not necessarily have symptoms, and the symptoms of each patient are not exactly the same. Chronic kidney failure refers to the damage to the kidneys by various chronic kidney diseases, eventually leading to the kidneys' inability to adequately excrete metabolic waste, causing the accumulation of water and metabolic waste in the body. This leads to disturbances in the patient's electrolytes and may also present clinical symptoms such as anemia and hypertension. However, not all patients feel discomfort, so chronic kidney failure is also known as the silent killer. If a patient undergoes a blood test, it will show an increase in blood creatinine and urea nitrogen, which is the only common feature among all patients with chronic kidney failure.
