The danger of an enlarged spleen is not the danger of large size, but only the large footprint that makes the patient feel uncomfortable with a distended and bulging stomach, and even pressure on the stomach and intestines, resulting in gastrointestinal discomfort, but not intolerable. The important danger of an enlarged spleen is hyperfunction, which is not only large but also powerful, and powerful enough to cause a significant decrease in blood cells. Clinically, hypersplenism is so severe that it is so severe that white blood cells are only 1/10 of normal, platelets are as low as 1/20 of normal, red blood cells are also very low, and hemoglobin may be as low as half the normal level. So, the problem with a large spleen is not in the size of the volume, but its power, which leads to a decrease in platelets and white blood cells. White blood cells are immune cells, and with lowered white blood cells, immune function becomes poor. Platelets are the cells involved in blood clotting, and low platelets cause bleeding gums, bleeding skin, and blood flow when touched.
