Uremia is very common in clinical practice. It is mainly caused by abnormal kidney functions, leading to abnormalities in glomerular filtration, as well as in the reabsorption and secretion functions of the renal tubules, which results in a series of symptoms. Once uremia occurs, it can disrupt the internal environment of the body, cause electrolyte abnormalities, and even lead to life-threatening arrhythmias. Uremia is very dangerous in clinical practice and often requires regular hemodialysis treatment. Therefore, once uremia occurs, medical attention must be sought promptly.
