Hypomagnesemia and PTH
One point which gets you an easy point but otherwise easy to miss is that hypomagnesemia can cause hypocalcemia since magnesium is necessary for the production of PTH.
| | PTH | Calcium | Phosphate | Si/sx |
| Primary Hyperparathyroidism | ↑ | ↑ | ↓ | stones, bones, abdominal groans and psychic moans" |
| Chronic Renal Failure (→Vit D def.) | ↑ | ↓ | ↑ - can’t be excreted | |
| Hypercalcemia (malignancy) | ↓ | ↑ | ↑ | |
| Hypomagnesemia | ↓ | ↓ | ↓ | Hypocalcemia that responds to Mg 2+ infusion |

Would there be high phosphate in hypomagnesemia because there is less Ca to complex with phosphate in the blood?
