Patients with end-stage renal disease often present with a variety of clinical manifestations due to the accumulation of waste products and fluid imbalances. Volume overload is a common symptom, leading to peripheral edema, pulmonary edema, and poorly controlled hypertension. Anemia is another hallmark of ESRD, primarily due to a deficiency in erythropoietin, a hormone produced by the kidneys that stimulates red blood cell production. This leads to symptoms such as fatigue, reduced exercise tolerance, and cognitive impairment. Anemia can also exacerbate cardiovascular conditions, such as left ventricular hypertrophy and heart failure.
Additional complications include hyperphosphatemia, hyperparathyroidism, and hypocalcemia, all of which contribute to bone disease and mineral disorders. Patients may also experience uremic symptoms, such as nausea, vomiting, anorexia, pruritus, and neurological disturbances like peripheral neuropathy and uremic encephalopathy. Pericarditis, often associated with uremia, is a potentially life-threatening condition that can manifest in patients with advanced ESRD and necessitates urgent dialysis.
