An increase in red pulp can be a result of various conditions. Some of the common causes include:
Splenomegaly: Enlargement of the spleen can lead to increased red pulp. Hemolytic anemia: Increased destruction of red blood cells can cause a compensatory increase in red pulp. Infections: Certain infections, such as malaria, can lead to increased red pulp due to heightened immune activity and splenic filtration. Myeloproliferative disorders: Conditions like polycythemia vera can lead to increased red pulp due to an overproduction of blood cells.
