Area of Science:

• Endocrinology
• Metabolic Syndrome Research
• Nutritional Science

Background:

• Hypovitaminosis D is a growing concern, particularly in individuals with obesity.
• Bariatric surgery (BS) candidates often present with multiple comorbidities associated with metabolic syndrome.
• The relationship between vitamin D status and metabolic health in BS candidates requires further investigation.

Purpose of the Study:

• To determine the prevalence of hypovitaminosis D (vitamin D deficiency) in patients undergoing bariatric surgery.
• To explore the association between low vitamin D levels and risk factors for metabolic syndrome in this population.

Main Methods:

• A cohort of 56 Caucasian patients undergoing BS were assessed for clinical, anthropometric, and biochemical parameters.
• Patients were categorized into vitamin D sufficiency (≥ 40 ng/ml), insufficiency (20-40 ng/ml), and deficiency (< 20 ng/ml) groups.
• Statistical analyses were performed to correlate vitamin D levels with body mass index (BMI), parathyroid hormone (PTH), fat mass, and components of metabolic syndrome.

Main Results:

• Vitamin D deficiency was observed in 75% of the study participants.
• Patients with vitamin D deficiency exhibited significantly higher BMI and lower plasma PTH concentrations.
• A higher incidence of type 2 diabetes mellitus (DM2) and dyslipidemia (DLPM) was noted in the vitamin D deficient group.
• Significant negative correlations were found between 25(OH)D levels and fat mass, BMI, and hypertension.

Conclusions:

• Vitamin D deficiency is extremely common in bariatric surgery candidates and is associated with type 2 diabetes and dyslipidemia.
• While optimal treatment strategies require further research, routine screening for vitamin D deficiency is crucial for individuals with morbid obesity.
• These findings underscore the importance of addressing vitamin D status in the management of obesity and metabolic health.
