Iron के लिए Post-Bariatric Nutritional Support

B संबंधित साक्ष्य कम से कम एक यादृच्छिक परीक्षण इसका समर्थन करता है, जिसके परिणाम अधिकतर सुसंगत हैं।

Iron deficiency occurs in 33-55% of post-bariatric patients. ASMBS guidelines recommend 45-60 mg elemental iron/day after gastric bypass. Ferrous bisglycinate is the preferred form for tolerability. Monitoring every 3-6 months is mandatory.
