Question [CLICK ON ANY CHOICE TO KNOW THE RIGHT ANSWER]
Diabetes insipidus is a rare type of diabetes caused by inadequate secretion of ____ by the pituitary gland.
A
ADH
B
ACTH
C
FSH
D
MSH
Explanation: 

Detailed explanation-1: -Diabetes insipidus is caused by a lack of antidiuretic hormone (ADH), also called vasopressin, which prevents dehydration, or the kidney’s inability to respond to ADH. ADH enables the kidneys to retain water in the body. The hormone is produced in a region of the brain called the hypothalamus.

Detailed explanation-2: -Diabetes insipidus is caused by problems with a hormone called vasopressin (AVP), also called antidiuretic hormone (ADH). AVP plays a key role in regulating the amount of fluid in the body.

Detailed explanation-3: -Deficiency of ADH is usually due to hypothalamic-neurohypophyseal lesions (central diabetes insipidus) or insensitivity of the kidney to ADH (nephrogenic diabetes insipidus). These patients, if untreated, have the predictable result of dehydration, hyperosmolality, hypovolemia, and eventual death in severe cases.
