Complications

By Mayo Clinic staff

Potential complications of an enlarged spleen are:

  • Infection. Because an enlarged spleen can reduce the number of healthy red blood cells, platelets and white cells in your bloodstream, you may develop frequent infections. Anemia and increased bleeding also are possible.
  • Ruptured spleen. Even healthy spleens are soft and easily damaged, especially in car crashes. When your spleen is enlarged, the possibility of rupture is far greater. A ruptured spleen can cause life-threatening bleeding into your abdominal cavity.
