Enlarged Spleen
The spleen is a fist-sized organ placed on the upper left side of the stomach, just below the left ribs. On the other hand, the liver produces proteins and cholesterol, used by the body for clotting, which is then converted into hormones, vitamins, and the membranes of cells. Along with the spleen, it functions as a filter that flushes hazardous wastes out of the body. It also contributes to the transformation of food into energy.
Because of the interdependent function between the two organs, diseases and symptoms associated with the liver also affect the spleen. An enlarged liver may also cause an enlargement of the spleen, known as hepatosplenomegaly. When the length of the spleen is more than 12 centimeters, and its weight is more than 400 grams, this is considered an enlarged spleen.
Blood may get backed up in the portal vein due to the restriction of blood flow via the liver, which can be caused by liver diseases such as cirrhosis and liver scarring. This can lead to increased pressure in the portal vein, known as portal hypertension. As a consequence of this, the spleen fills up with blood, which results in the condition known as splenomegaly.
