Splenic disorders refer to conditions that affect the spleen, an organ located in the upper left abdomen. The spleen plays a crucial role in filtering blood, recycling iron, and supporting the immune system. Common disorders include splenomegaly, which is an enlargement of the spleen, and hypersplenism, where the spleen overactively removes blood cells, leading to anemia or low platelet counts. Other splenic disorders can arise from infections, such as mononucleosis, or conditions like sickle cell disease that affect blood flow. Treatment options vary depending on the disorder and may include medication, lifestyle changes, or, in severe cases, splenectomy, the surgical removal of the spleen.
