Anterior pituitary function in women with postpartum hemorrhage.

Thirteen asymptomatic women with postpartum blood loss of at least 500 cc were evaluated for anterior pituitary endocrine function. Insulin tolerance tests and TRH stimulation tests were done and determinations made for serum growth hormone, cortisol, thyrotropin, and prolactin. There was no laboratory evidence of pituitary dysfunction in this group of 13 patients. Subclinical hypopituitarism in women with previous postpartum hemorrhage would appear to be uncommon.
