General: To determine serum vitamin D levels in obese patients who will undergo bariatric surgery in Venezuela. Methods: Descriptive research, not experimental, cross-sectional design that included 32 consecutive patients who fulfilled criteria for bariatric surgery and signed informed consent. It was determined age, gender, co-morbidities, place of origin. Measurements of weight (kg) and height (m) were taken and BMI was calculated, according to which the degree of overweight and obesity was determined. Measurements of serum vitamin D and bone metabolic profile such as serum calcium, calcium/creatinine ratio, serum phosphorus, creatinine, alkaline phosphatase, C-Telopeptide (CTX), parathormona (PTH), and urinary determinations such as urinary calcium, phosphorus urine and tubular reabsorption of phosphate, were performed. Results: Females predominated, 25 cases (78.1%). The average age was 39.41 ± 10.99 years. The co-morbidities frequently associated with obesity were: hypertensive heart disease (37.5%), diabetes mellitus (21.9%) and hypothyroidism (18.8%). Obesity grade III was presented in 50% of cases for both sexes. The biochemical parameters of bone metabolism ranged within the normal range, however, the Vitamin D average was low, 26.27±9.76 ng/ ml; 80% were in the range of insufficiency, < 30 ng/ml and 32% in the range of deficiency, < 20 ng/ml. Conclusion: The Venezuelan obese patients who are going to undergo bariatric surgery have a decrease in serum levels of vitamin D, with a high percentage in the range of insufficiency and deficiency, similar to those reported in studies conducted worldwide.
