The spleen is an organ located in the upper left side of the abdomen, in the upper area beneath the ribs, and its normal size is approximately the size of a fist. The spleen performs vital functions within the lymphatic system: it filters blood, fights infection through white blood cells, destroys old or damaged blood cells, and helps regulate blood volume in the body [\[1\]](). When the spleen is enlarged, it is usually a response to an underlying medical condition affecting these functions, which is why doctors focus on identifying the root cause rather than merely treating the enlargement itself. ## When does splenomegaly become a cause for concern? The true danger of splenomegaly lies in the complications that may arise from it, not necessarily in the presence of the enlargement as an isolated symptom. One of the most significant risks is the potential for splenic rupture; an enlarged spleen is more susceptible to injury and rupture if the abdomen suffers trauma or injury. Furthermore, an enlarged spleen impacts the body's ability to maintain a balance of blood cells and its ability to resist infection [\[1\]](). Therefore, any pain in the upper left side of the abdomen requires medical attention, especially if accompanied by symptoms like early satiety (feeling full early when eating), which is a common symptom resulting from the pressure of an enlarged spleen on the adjacent stomach [\[2\]](). ## The difference between splenomegaly and hypersplenism It is essential to distinguish between splenomegaly and the condition known as "hypersplenism." Hypersplenism refers to a condition where the organ is overactive, removing blood cells from circulation too rapidly and excessively, leading to decreased levels of one or more types of blood cells. While this condition is often associated with splenomegaly, it is not always necessary for the spleen to be enlarged to diagnose hypersplenism [\[2\]](). The causes leading to these disorders are diverse and include conditions such as advanced liver cirrhosis, lymphoma, malaria, tuberculosis, and some inflammatory connective tissue diseases [\[2\]](). ## Treatment options and living without a spleen Treatment is primarily based on addressing the underlying cause of splenomegaly. In certain cases, the medical team may decide to perform surgery to remove the spleen (splenectomy), especially if the organ is significantly damaged or if it causes uncontrollable health complications. The good news is that humans can live without a spleen; other organs in the body, such as the liver, take over some of the spleen's functions. However, the patient must realize that the absence of a spleen reduces the body's ability to fight certain types of infections, which requires ongoing medical follow-up [\[1\]]().
