Antidiuretic hormone dysfunction syndrome

Syndrome of inappropriate secretion of antidiuretic hormone (SIADH) was first reported by Schwartz in 1957, because the excessive secretion of antidiuretic hormone (ADH, AVP) or similar antidiuretic hormone-like substances caused the water Caused by obstruction of excretion, the changes are characterized by hyponatremia. SIADH is a series of clinical manifestations such as antidiuretic hormone (ADH) that does not adjust to the plasma osmotic pressure and secretes abnormally, resulting in increased water retention in the body, increased sodium excretion, and dilute hyponatremia. In addition to severe craniocerebral injury, cervical spinal cord injury, severe intracranial infection, and acute phase of cerebrovascular disease (10% to 14%), there are malignant tumors and lung tumors.
