Blood Balance Kidneys Effects Urea Describe Failure Loss

Kidney failure results in several adverse effects, including electrolyte imbalance, accumulation of toxic urea, elevated blood pressure, bone weakening, joint pain and stiffness, and anemia.

Kidney failure leads to electrolyte imbalance, toxic urea buildup, high blood pressure, weakened bones, pain and stiffness, and anemia due to reduced RBC stimulating hormone production.

Front Describe 6 effects of kidney failure.
Back Effects of kidney failure:
  • Loss of electrolyte balance - body cannot excrete excess Na, K, Cl ions
  • Build-up of toxic urea in blood - kidneys cannot remove urea - poisons cells
  • High blood pressure - kidneys no longer able to maintain water balance of blood
  • Weakened bones - calcium/phosphorus balance in blood is lost
  • Pain and stiffness - abnormal protein buildup
  • Anaemia - kidneys involved in production of hormone that stimulates RBC formation
