Myopathy in certain specified endocrine disease

Definition

Myopathy in certain specified endocrine disease refers to muscle disorders associated with adrenal dysfunction (as steroid myopathy), thyroid dysfunction (as in myxoedema coma or thyrotoxic myopathy), parathyroid dysfunction (as in multiple endocrine neoplasia), pituitary dysfunction, and islands of Langerhans dysfunction (as in diabetic myopathy from ischemic infarction of the femoral muscles). Steroid myopathy is the most common endocrine myopathy. These conditions are usually reversible with correction of the underlying endocrine disturbance.
