根据梅奥诊所的说法，脾大的症状包括： http://www.mayoclinic.org/diseases-conditions/enlarged-spleen/basics/symptoms/con-20029324
脾大可能会导致：
No symptoms in some cases Pain or fullness in the left upper abdomen that may spread to the left shoulder Feeling full without eating or after eating only a small amount — this can occur when an enlarged spleen presses on your stomach Anemia Fatigue Frequent infections Easy bleeding
和许多疾病一样，脾大的症状是非特异性的，与许多其他疾病相同，所以没有单一的症状或一组症状可以鉴别。诊断时，需要医生进行检查。
