D73: Diseases of spleen

D73.1: Hypersplenism

The spleen is on the top left side of the abdomen. Old blood cells are broken down in the spleen. Furthermore, defense cells are stored. If the defense cells are needed, they are then released from the spleen into the blood.

Your spleen is enlarged and, as a result, over-active. An over-active spleen breaks down too many blood cells. This can cause a blood cell deficiency.

Blood is made up of a liquid part and different blood cells, among other things. The blood cells include the red blood cells, the white blood cells and the platelets. The red blood cells carry oxygen from the lungs throughout the body. White blood cells are part of the body’s immune system. They fight pathogens. Platelets are important for blood clotting.

When a person has too few blood cells, they can look pale and feel weak. They may also be more susceptible to infections and bleed more easily than usual.
