D47.4: Osteomyelofibrosis

Your bone marrow is not working properly. As a result, you have too few or defective blood cells in your blood.

The bone marrow is inside bone. The blood cells are formed in the bone marrow of some of the bones. There are 3 different types of blood cell: red blood cells, white blood cells and platelets. Red blood cells are important for carrying oxygen in the blood. White blood cells are part of the body’s immune system. They fight pathogens. Platelets are important for clotting blood.

Your bone marrow is not working properly. It is not producing the right amount of the different blood cells. It is also possible that defective blood vessels are being formed. The symptoms can vary greatly. You can feel weak or get sick more often. It is also possible that you will bleed for longer than normal or have blood clots in your body. You may also have no symptoms at all.

After a long time, the bone marrow develops scarring. You then see lots of connective tissue and more bone tissue than normal in the bone marrow. Haematosis (blood formation) no longer takes place in the bone marrow, but in another place in the body. This can be in the spleen or liver, for example. However, it is often not enough and you then have too few blood cells in your blood.
