What would happen to a person who has undergone a splenectomy?

A person who has undergone a splenectomy, which is the surgical removal of the spleen, experiences significant changes in their immune function and blood composition. The spleen plays a crucial role in filtering blood, recycling iron, and fighting off certain types of infections, particularly those caused by encapsulated bacteria. When the spleen is removed, the body loses a vital organ that contributes to the immune response.

As a result, individuals become more susceptible to infections, especially from bacteria such as Streptococcus pneumoniae, Neisseria meningitidis, and Haemophilus influenzae, which can lead to severe septic infections. Vaccinations against these pathogens and prophylactic antibiotics may be recommended post-splenectomy to mitigate this increased risk.

Understanding this, the correct choice accurately reflects the heightened infection risk associated with the absence of the spleen, highlighting the need for continued medical care and preventive measures for those who have undergone this procedure.
