Abnormal phosphate levels can result from various conditions:
Hypophosphatemia: Low phosphate levels can be caused by malnutrition, chronic alcoholism, vitamin D deficiency, hyperparathyroidism, or the use of certain medications like diuretics and antacids. Hyperphosphatemia: High phosphate levels can result from kidney failure, hypoparathyroidism, excessive dietary intake, or the use of phosphate-containing laxatives.
