Laparoscopic Sleeve Gastrectomy and Nutrient Deficiencies: A Prospective Study.

Area of Science:

• Bariatric surgery
• Nutritional science

Background:

• Laparoscopic sleeve gastrectomy (LSG) is a common weight-loss procedure.
• Mechanisms include gastric restriction and neurohormonal changes.
• Nutritional effects of LSG require further investigation.

Purpose of the Study:

• To prospectively assess vitamin and micronutrient deficiencies after LSG.
• To determine the timing ('whats and when') of these deficiencies.
• To guide organized follow-up protocols.

Main Methods:

• 112 patients underwent LSG between June 2010 and December 2013.
• Pre-existing deficiencies were corrected before surgery.
• Nutrient levels were monitored at 2, 4, 6, 9, and 12 months post-LSG.

Main Results:

• The study included 112 patients (65% female), mean age 26, mean BMI 41.
• Nutrient deficiencies and complications were observed throughout the follow-up.
• Analysis focused on the incidence and patterns of deficiencies.

Conclusions:

• Vitamin and nutritional deficiencies are frequent after LSG.
• Preoperative correction, adequate postoperative supplementation, and long-term follow-up are essential.
• Proactive management prevents serious deficiency-related complications.
