This is because your umbilicus has become colonised by cyanobacteria. These have a protein called cyanoglobin in their membrane walls which binds irreversibly with oxygen to form a blue pigment. There is no known cure and eventually all of your orifices will become blue (see Blue-Ring thread below).
Hope this helps.
