Multiple Endocrine Neoplasia Type I
What are the causes?
MEN I occurs where two or more of the following endocrine glands develop tumours (hyperplasia or adenoma); the pancreas which is located behind the stomach; the parathyroid gland which is located in the neck; and the pituitary gland which is located in the head. Normally, hormones are secreted by endocrine glands in a carefully balanced way to regulate specific body functions and meet the body's needs. The presence of tumours in MEN I results in the over-production of hormones and this is associated with a range of medical problems. Over-activity of more than one endocrine gland may occur at the same time or later on in a person's life.
