Accidental pituitary stalk damage will cause all except
Diabetes mellitus
Diabetes mellitus is a chronic disease caused by inherited and/or acquired deficiency in the production of insulin by the pancreas, or by the inability of the insulin produced to function. It is not dependent on the hormone produced by the pituitary gland.
Diabetes insipidus is caused by hyposecretion of antidiuretic hormone (ADH) which is secreted by the posterior pituitary gland.
Hypothyroidism is a result of low levels of thyroid hormone which in turn is regulated by thyroid secreting hormone (TSH) released by the anterior pituitary gland.
Addison's disease takes place due to insufficient amounts of certain hormones produced by your adrenal glands. Secretion of adrenal hormones is controlled by Adrenocorticotropic hormone (ACTH) secreted by the anterior pituitary gland.
