HELLP includes three problems:

  • Hemolysis is the break down of red blood cells. This can lead to anemia.
  • Liver enzymes are chemicals in the blood that show how well the liver is working. High levels of enzymes mean the liver has been damaged.
  • Platelets help stop bleeding. A low level of platelets can lead to problems with bleeding.
