Hemolytic anemia is defined by the premature destruction of red blood cells, and can be chronic or life-threatening. It's passed on from parents to children through genes. BUT – In patients with sickle cell anemia, something goes wrong with their hemoglobin causing it to form sharp, stick like structures called fibers (Think of putting pencils in a rubber balloon) This reduces protein’s ability to hold on to oxygen and also gives the blood cell the “sickle” shape causing it to clog up blood vessels. Hemoglobin is a protein in red blood cells that carries oxygen throughout the body. Sickle cell anemia Anemia - sickle cell; Hemoglobin SS disease (Hb SS); Sickle cell disease. These sickle cells get stuck in the blood vessels, blocking the flow of blood, which can be really painful (NHS 2016a, RCOG 2011).

Sickle cell anemia can destroy the organs of the body. A round disc is the healthiest shape for red blood cells because they can move easily through the blood vessels of the body to get oxygen where it. People with this disorder have atypical hemoglobin molecules called hemoglobin S, which can distort red blood cells into a sickle, or crescent, shape. Sickle cell with hemoglobin C disease (HbSC). Sickle-cell anemia is a genetic condition, so the disease cannot be avoided if you inherit the genes. Autosomal means that the gene is not located on either the X or Y sex chromosome.
