This article is about the medical condition. For the moth genus, see Asplenia (moth). For the fern genus, see Asplenium.
Asplenia refers to the absence of normal spleen function and is associated with some serious infection risks. Hyposplenism is used to describe reduced ('hypo-') splenic functioning, but not as severely affected as with asplenism.
Functional asplenia occurs when splenic tissue is present but does not work well (e.g. sickle-cell disease, polysplenia) ā such patients are managed as if asplenic ā while in anatomic asplenia, the spleen itself is absent.
