Hyperphosphatemia Flashcards
1
Q
Mechanisms
A
Increased intake or absorption
-Transcellular shifting
-Decreased renal excretion
-Multifactorial
2
Q
Increased intake
A
-High P diets
-Administration of P compounds
-Hypervitaminosis D
3
Q
Transcellular shifting
A
-Acute tumor lysis -> release intracellular contents
-Severe soft tissue trauma-> release contents
4
Q
Decreased urinary excretion
A
-Decreased GFR
-Urinary bladder rupture
-Decreased PTH
5
Q
Neonates and young
A
-Increased GH-> increases vitamin D, increased resorption
-Bone growth
6
Q
Acromegaly
A
Increased GH-> increases vit D and increased renal reabsorption of P
