A common treatment for hereditary spherocytosis is splenectomy, which involves the surgical removal of the spleen. This procedure is particularly effective because the spleen plays a critical role in filtering blood and removing abnormal red blood cells, including spherocytes, which are present in this condition. By removing the spleen, the destruction of these abnormally shaped red blood cells is significantly reduced, leading to an increase in their lifespan and thus alleviating symptoms associated with anemia.

The other options do not appropriately address the underlying pathology of hereditary spherocytosis. Surgical resection of the stomach is unrelated to this blood disorder. Oxygen therapy is beneficial for conditions related to respiratory issues or hypoxia but does not impact the underlying cause or treatment of hereditary spherocytosis. Insulin administration is relevant for managing diabetes and does not pertain to the treatment of hereditary spherocytosis.
