Uremic symptoms of renal failure?

summary

Uremia is the most serious stage of renal failure. At this time, a large number of nephrons have been destroyed, and a large number of metabolites and poisons have accumulated in the body. The water electrolyte, acid-base balance disorder, and renal endocrine function are serious disorders. Patients themselves have developed systemic poisoning syndrome, basically uremic patients can only rely on hemodialysis to maintain life, or surgery to transplant a kidney to compensate. The symptom of uremia is systemic more, will introduce one by one below.

Uremic symptoms of renal failure?

In uremic stage, the patient showed oliguria due to the destruction of nephron. And urine contains a lot of protein, red blood cells and various tube types. Due to the disorder of water and electrolyte, the increase of blood sodium leads to water retention, edema and hypertension. The increase of serum potassium can cause malignant arrhythmia and endanger the life of patients.

In uremic stage, a large number of toxic substances accumulate in the body, which will inhibit the function of platelets and lead to bleeding tendency. Gastrointestinal bleeding is the earliest symptom of uremic patients. In addition, toxic substances can also inhibit the cellular immune function of patients, resulting in low immune function, prone to various infections, toxic substances can also stimulate the skin sensory nerve endings, patients with skin itching, dry and other symptoms.

In addition, most uremic patients may also have dysfunction of the central nervous system. Patients with memory loss, thinking is not concentrated, restless and so on. More serious can show drowsiness, convulsion and even coma. At this time, the accumulation of toxic substances in patients has affected the function of the brain.

matters needing attention

In the period of uremia, if the conditions of patients do not allow renal transplantation, then most of them have to carry out hemodialysis. When dialysis, special attention should be paid to the cleaning of the wound. Because the immune function of patients has been inhibited, so multiple infections, which is also a common cause of death in uremia patients.
