Study Notes
Hypocalcemia Causes
- Insufficient parathyroid hormone (PTH) impairs calcium regulation.
- This leads to increased calcium storage in bone and higher calcium excretion by the kidneys.
- Reduced vitamin D levels result from the lack of PTH's role in vitamin D metabolism.
- This further decreases calcium levels.
- Primary hypoparathyroidism arises from gland aplasia, destruction, or removal.
- Chronic hypomagnesemia, a growing issue in hospitalized patients, is a frequent cause.
