VITAMIN D LEVELS AND LIPID PROFILE IN PATIENTS UNDERGOING BARIATRIC SURGERY

Area of Science:

• Endocrinology
• Metabolic Surgery
• Nutritional Science

Background:

• Bariatric surgery patients face short- and long-term vitamin, mineral, and metabolic deficiencies.
• These deficiencies are significant postoperative complications requiring careful management.

Purpose of the Study:

• To investigate the relationship between serum vitamin D levels and lipid profiles in obese patients following bariatric surgery.
• To identify specific associations between vitamin D and lipid parameters in different bariatric procedures.

Main Methods:

• A case series study involving 156 patients undergoing sleeve gastrectomy or Roux-en-Y gastric bypass from 2010 to 2018.
• Collection of sociodemographic, clinical, laboratory, and anthropometric data preoperatively and at 6, 12, and 24 months post-surgery.

Main Results:

• Only 18.9% of patients had adequate preoperative vitamin D levels (≥30 ng/mL).
• Surgery led to weight reduction and improved lipid profiles.
• Significant correlations between vitamin D and lipids were found in Roux-en-Y gastric bypass patients: negative with total cholesterol and HDL at 2 years, positive with triglycerides at 1 year.

Conclusions:

• Routine monitoring of vitamin D and lipid profiles is essential before and after bariatric surgery.
• Early detection and management of vitamin D deficiency can mitigate associated health risks.
