Hypophosphatemia can occur when there is decreased phosphorus intake (decreased intestinal absorption or increased gastrointestinal losses), or excess renal wasting from renal tubular defects or hyperparathyroidism. In the case of cellular shifts, total body phosphorus may not be depleted. By convention, hypophosphatemia is often graded as mild (< 3.5 mg/dl), moderate (< 2.5 mg/dl) and severe (< 1.0 mg/dl). Moderate and severe hypophosphatemia will generally only occur when there are multiple problems. The causes of hypophosphatemia are shown in Box 2.
Medical manifestations from hypophosphatemia
Hypophosphatemia is a very common shopping for noticed in 3% of the many hospitalized patients, 10% away from hospitalized alcoholic clients, and you may 70% regarding ventilated ICU customers 25 . Warning signs of hypophosphatemia usually are simply noticed in patients having modest or severe hypophosphatemia and include strength tiredness (and you may difficulties weaning away from ventilator), hemolysis, impaired platelet and you will WBC setting, rhabdomyolysis, plus in rare cases neurologic issues. Hypophosphatemia is probably over-treated about ICU, in which the “hard to wean” patient is given phosphorus in the event the lower levels seem to be due to mobile shifts out-of respiratory alkalosis. A cautious writeup on the fresh new pattern in gel phosphorus which have arterial bloodstream pH might help detect and therefore people must be managed.
Differential Medical diagnosis regarding hypophosphatemia
The differential diagnosis, and treatment approach will be based on the cause and site of phosphate loss (list 2). Usually the cause is clinically apparent, but if not, the simplest test is to measure a 24 hr urine phosphorus. In the setting of hypophosphatemia, the kidney should be retaining (reabsorbing) all phosphorus.
