The kidneys filter the blood and excretion of waste and surplus fluid from the human body to the urine. When the kidneys are damaged, waste and excess fluids accumulate in the body, which can lead to high blood toxins, body fluids, swelling of the feet, eyes, high temperature and so on. Most often, a patient with renal failure does not feel any symptoms until the disease deteriorates to the last stage, so renal failure has another name called the silent killer. So, what are the symptoms of kidney failure? They include: • Decrease urine intake • Nausea • vomiting • Lack of appetite • Tiredness and weakness • Sleep difficulties • Low thinking • Muscle contraction • And wrists with ankles and legs • Itch These symptoms are not limited to kidney damage, but may also occur when other diseases are present. In addition, the kidneys have a high ability to compensate for the damage, so it is possible to delay the diagnosis of the disease and the occurrence of a persistent kidney function.
Thank you very much to help my family. Much appreciated.
