    - Multiple endocrine neoplasia type 1 (MEN1) is an inherited disorder that causes hormone-secreting tumors in the duodenum and the endocrine glands-most often the parathyroid, pancreas, and pituitary.  - Overactive parathyroid glands can lead to tiredness, weakness, muscle or bone pain, constipation, indigestion, kidney stones, or thinning of bones.
