REMEMBER: like the fight/flight; happens fast
What does GH stand for?
Where is GH secreted from?
What does GH do?
GH stand for growth hormone.
GH is secreted from Anterior pituitary.
GH stimulates growth of bone and muscle, promotes protein synthesis and fat metabolism, decreases carbohydrate metabolism.

Where is ADH secreted from?
What does ADH do?
ADH stands for Antidiuretic hormone.
ADH is secreted from Posterior pituitary.
ADH increases water reabsorption by the kidney.
What does TSH stand for?
Where is TSH secreted from?
What does TSH do?
TSH stand for Thyroid-stimulating hormone.
TSH is secreted from the Anterior pituitary.
TSH stimulates synthesis and secretion of thyroid hormone.
What does ACTH stand for?
Where is ACTH secreted from?
What does ACTH do?
ACTH stand for Adrenocorticotropic hormone.

Cushing's Syndrome is excess ACTH affects adrenal glands.
It is a disorder of the Anterior Pituitary
Acromegaly is a disorder of the Anterior or Posterior Pituitary?
It involves excess or deficiency?
Excessive secretion of GH;causes progressive enlargement of peripheral body parts
Hypopituitarism is a disorder of the Anterior or Posterior Pituitary?
It involves excess or deficiency?
Can result from disease/deficiency of the pituitary gland itself or disease of the hypothalamus; the result is essentially the same
What is Acromegaly?
Excess GH after the epiphyseal plate closure
What is the Epiphyseal plate closure?
Once the body reaches maturity, all the cells responsible for new bone growth ossify or solidify into bone and this progression stops, thus bringing on epiphyseal closure. At this time the plate transforms into the epiphyseal line, the only remnant of the growth process.When problems occur with the epiphyseal closure of a bone or bones, changes in the body’s structure or height can be evident. For example, if epiphyseal closure occurs before full maturity is reached, normal height may not be attained. When closure does not occur, the long bones will continue to grow allowing the individual to surpass natural height. These abnormal changes can also affect the shape of the long bones and create irregular formation resulting in deformities.

Bone & soft tissue deformities R/T enlargement of the visera w/o increase in height
Other problems like disfigurement and sever complications and premature death

- urine (water-like)
- –Can drink about 2-20 L
- •Neuro changes
Should you try to control DI by restricting or limiting fluid intake?
The disease cannot be controlled by limiting fluid intake,because the high-volume loss of urine continues even without fluid replacement. Attempts to restrict fluids cause the patient to experience an insatiable craving for fluid and to develop hypernatremia and severe dehydration.
What 4 diagnostic tests are done to diagnose DI?
1) Fluid Deprivation test
2) Plasma Levels of ADH & osmolaltiy
3) Urine Osmolality
4) Synthetic Vasopressin trial
What is the Fluid Deprivation Test?
Test done to diagnose DI. The fluid deprivation test is carried out by withholding fluids for 8 to 12 hours or until 3% to 5% of the body weight is lost. The patient is weighed frequently during the test.Plasma and urine osmolality studies are performed at the beginning and end of the test. The inability to increase the specific gravity and osmolality of the urine is characteristic of DI. The patient continues to excrete large volumes of urine with low specific gravity and experiences weight loss,increasing serum osmolality, and elevated serum sodium levels. The patient’s condition needs to be monitored frequently during the test, and the test is terminated if tachycardia,excessive weight loss, or hypotension develops.
