Low serum phosphorus requires treatment of the primary disease and appropriate phosphorus supplementation.
A blood phosphorus concentration of less than 0.8 mmol/L is called hypophosphatemia, and the causes are often reduced phosphorus absorption from the small intestine, such as starvation, vomiting, diarrhea, increased urinary excretion, such as acute ethanol intoxication, hyperparathyroidism, and intracellular transfer of phosphorus, if insulin and androgens are applied.
Patients with hypophosphatemia usually have no specific symptoms, patients with mild cases often have no clinical symptoms, and patients with severe cases can have muscle weakness, sensory abnormalities, bone pain, duck steps, irritability, confusion, convulsions, and coma.
The first principle of hypophosphatemia treatment is to find removable causes, in addition, according to the degree of blood phosphorus lowering and clinical symptoms of appropriate phosphorus supplementation, such as the application of phosphates and so on. It is recommended to use drugs under the guidance of a doctor and avoid self-medication.
