Micronutrient Deficiencies in Laparoscopic Sleeve Gastrectomy

Area of Science:

• Bariatric Surgery
• Nutritional Science
• Gastroenterology

Background:

• Laparoscopic sleeve gastrectomy (SG) is a common bariatric procedure.
• Nutritional deficiencies can occur post-SG, impacting patient health.
• Standardized recommendations for micronutrient supplementation after SG are lacking.

Purpose of the Study:

• To review the literature on micronutrient deficiencies following laparoscopic sleeve gastrectomy (SG).
• To identify trends and inconsistencies in recommended supplementation protocols.
• To provide evidence-based insights for clinical practice.

Main Methods:

• A comprehensive literature review was performed.
• Databases searched included PubMed and Cochrane.
• Seventeen articles meeting predefined inclusion criteria were analyzed.

Main Results:

• Iron, vitamin B12, and vitamin D were the most frequently studied micronutrients.
• Deficiencies in iron and vitamin B12 are prevalent post-SG.
• Evidence suggests routine iron and vitamin B12 supplementation is necessary, alongside a multivitamin.
• Vitamin D supplementation may not be universally required.

Conclusions:

• Consistent supplementation protocols for iron and vitamin B12 are needed post-SG.
• Further prospective research is required to clarify optimal micronutrient management.
• Current evidence does not strongly support routine vitamin D supplementation for all SG patients.
