Patients with chronic kidney failure often do not have any specific discomfort or noticeable symptoms in the early stages. However, some patients may exhibit clinical signs, such as edema, due to the kidneys' reduced ability to excrete water, or hypoproteinemia, which leads to a decrease in plasma colloid osmotic pressure, resulting in edema in the lower limbs or eyelids, and facial swelling. Patients may also experience visible blood in the urine, increased urinary foam, and chronic kidney failure often accompanies high blood pressure. Such patients may also suffer from mild renal anemia, hyperkalemia, and other clinical manifestations.
