Diabetes mellitus following pituitary adenomectomy in euglycemic patients with acromegaly

ABSTRACT

Insulin resistance, impaired glucose tolerance and diabetes mellitus [DM] secondary to acromegaly generally improve following treatment of the underlying disease. In rare cases, in spite of normoglycaemia in the presence of active acromegaly, patients develop diabetes mellitus following pituitary adenomectomy to the extent of requiring insulin therapy. We report 7 patients who developed diabetes mellitus after pituitary adenomectomy. Regular measuring of blood glucose in post-pituitary surgery patients is recommended as a necessary step even in the previously normoglycaemics
