What does low serum inorganic phosphate mean?
Hypophosphatemia may be described as low levels of inorganic phosphate in the blood. Phosphate, or phosphorous, is similar to calcium, and is found in your teeth and bones. You need vitamin D in order to absorb phosphate. The kidneys excrete (get rid of) phosphate from our bodies.
Causes include the following:
- Increased parathyroid hormone levels, as in primary and secondary hyperparathyroidism.
- Other hormonal disturbances, such as Cushing syndrome and hypothyroidism.
- Vitamin D deficiency.
- Electrolyte disorders, such as hypomagnesemia and hypokalemia.
- Theophylline intoxication.
- Long-term diuretic use.
- Common symptoms include:
- Abnormal eye movements (nystagmus)
- Muscle spasms or cramps.
- Muscle weakness.
- Administration of phosphate binders is the only truly long-term therapy for chronic hyperphosphatemia due to renal failure. Monitor calcium and phosphate levels, especially when treating patients with calcium-containing phosphate binders, because of the possibility of severe, life-threatening hypercalcemia.
- Diet changes
- Keep track of how much fluid you drink.
- Limit your intake of milk, cheese, cottage cheese, yogurt, and ice cream.
- Limit your intake of meat, fish, poultry, eggs, beans, and nuts.
- Avoid or eliminate soft drinks (soda pop).
- Avoid foods and drinks that contain added phosphorus or phosphates.
