Final answer:
Insulin would need to be replaced with drug therapy post-pituitary gland removal in a case of gigantism.
Explanation:
Insulin would have to be replaced with drug therapy if an adult patient is treated for gigantism by the removal of their pituitary gland. Gigantism is caused by excess production of growth hormone, which can lead to an abnormally increased height due to excessive bone growth. Insulin is essential for regulating blood sugar levels and is not directly related to gigantism; therefore, its replacement would be necessary following the treatment.
