Overview
Milk alkali syndrome is characterized by hypercalcemia, metabolic alkalosis, and renal dysfunction, often triggered by excessive intake of calcium and absorbable alkali, though it can also occur due to other factors like diuretic-induced alkalosis and polypharmacy 1.Diagnosis
Key Diagnostic Criteria: Hypercalcemia, metabolic alkalosis, renal dysfunction, hypophosphatemia, hypokalemia, hypomagnesemia 1.
Recommended Tests: Serum calcium, serum electrolytes (phosphate, potassium, magnesium), blood gas analysis, renal function tests (creatinine, BUN), ECG 1.Management
First-Line Treatments: Discontinue calcium and alkali supplements, fluid resuscitation, correction of electrolyte imbalances 1.
Adjunctive Treatments: Loop diuretics for hypercalcemia management, monitoring and treatment of renal function 1.Special Populations
Elderly: Increased risk due to polypharmacy and comorbidities; careful review of medications essential 1.
Comorbidities: Patients with osteoporosis, hypertension, diabetes, and Parkinson's disease require meticulous medication management to prevent syndrome 1.Key Recommendations
Identify and discontinue causative agents such as excessive calcium and alkali supplements promptly (Evidence: Strong 1).
Monitor and correct electrolyte imbalances including calcium, phosphate, potassium, and magnesium levels (Evidence: Strong 1).
Manage fluid status and renal function closely, considering diuretic use and hydration needs (Evidence: Moderate 1).
Review polypharmacy in elderly patients to prevent overlapping factors contributing to milk alkali syndrome (Evidence: Expert opinion 1).References
