Hyposplenism is a medical condition characterized by reduced or absent function of the spleen, an organ that plays a crucial role in filtering blood and fighting infections. This condition can result from various factors, including certain diseases, surgical removal of the spleen, or genetic disorders. Individuals with hyposplenism may be more susceptible to infections, particularly from encapsulated bacteria. Diagnosis of hyposplenism typically involves blood tests and imaging studies to assess spleen function. Treatment focuses on preventing infections, often through vaccinations and prophylactic antibiotics. Regular medical follow-up is essential to manage potential complications associated with this condition.
