Symptoms Caused by Pituitary Adenomas Pituitary adenomas are generally thought of as either hormone- producing or hormone-inactive tumors 1.Hormone-producing pituitary adenomas produce an active hormone in excessive amounts 2.Hormone-inactive(non-functional)pituitary adenomas typically cause problems related to the size of the tumor
Symptoms Caused by Pituitary Adenomas uPituitary adenomas are generally thought of as either or hormone-inactive tumors produce an active hormone in excessive amounts. typically cause problems related to the size of the tumor
Symptoms Caused by Pituitary Adenomas ◆Hormone-producing pituitary adenomas激素分泌型垂体腺瘤 The three most common hormone-producing adenomas are: 1.Prolactinoma泌乳素瘤：causes loss of menstrual periods and breast milk production in women. 2.Growth hormone-secreting pituitary adenoma生长激素瘤： excessive growth hormone(GH)production causes acromegaly in adults or gigantism in children. 3.ACTH-secreting pituitary adenoma:excessive ACTH hormone produced by the pituitary gland causes Cushing's disease库欣氏 4.Other tumors are very rare TSH producing Adenoma
