anaemia

Hereditary Spherocytosis or HS is a red blood cell disorder where the cells take on a shape of a ball (or sphere) instead of the normal shape of a red cell (which looks like a ‘doughnut)’. Because the red cells are in the shape of a ball they are more fragile than normal red cells. The fragile red cells can break down which is also known as red cell haemolysis and cause anaemia.
