How to supplement albumin deficiency

The reduction in albumin levels is caused by inadequate dietary intake or gastrointestinal diseases that impair absorption and digestion, leading to a deficiency of the raw materials required for protein synthesis. Other contributing factors include hepatic dysfunction, excessive consumption of albumin (e.g., due to hemorrhage or trauma), renal disease, decreased albumin synthesis, and increased albumin catabolism. First-line management involves increasing dietary intake of protein-rich foods. Proteins can be categorized as: - High-quality (complete) proteins—such as animal-derived proteins found in meat, fish, dairy products, and eggs; - Non-animal proteins—such as legumes and soy milk. Second-line interventions include intravenous albumin administration or supplementation with multiple amino acids via intravenous infusion.
