Hypophosphatemia
Introduction
Hypophosphatemia is a serum phosphate concentration<2.5 mg/dL (0.81 mmol/L). Causes include alcohol use disorder, burns, starvation, and diuretic use. Clinical features include muscle weakness, respiratory failure, and heart failure; seizures and coma can occur. Diagnosis is by serum phosphate concentration. Treatment consists of phosphate supplementation. (See also Overview of Disorders of Phosphate Concentration .) Hypophosphatemia occurs in 2% of patients who are hospitalized but is more prevalent in certain populations (eg, it occurs in up to 10% of patients with Alcohol Use Disorder and Rehabilitation who are hospitalized).
