The effect of laparscopic sleeve gasterectomy on vitamin D, Calcium and Fat metabolism

Abstract
Background: Obesity, defined as a body mass index >30 kg/m2, is a growing worldwide epidemic currently effecting 1 in 10 adults, with rates as high as 40% in the United States.
Aim of the work: To study the effect of sleeve gastrectomy on vitamin(D), Calcium, Cholesterol and Triglyceride homeostasis with early detection of abnormalities and their proper management.
Patients and Methods: This prospective case series study was carried out on 40 morbidly obese patients at the surgical departments in Kasr Al-ainy and Sayed Galal Hospitals. These patients underwent sleeve gastrectomy operation by the standard technique and preoperative (immediately before surgery) & postoperative (3 & 6 months) assessment of vitamin & micronutrient deficiencies was done.
Results: The prevalence of preoperative vitamin and micronutrient deficiency in our study was as follows: 24 (12 deficiency and 12 insufficiency) of the 40 patients (60%) had vitamin D deficiency, 18 of the 40 patients (45%) had hypocalcemia. The prevalence of vitamin and micronutrient derangements at 3 months was as follows: 30 (8 deficiency and 22 insufficiency) of the 40 patients (75%) had vitamin D deficiency, 23 of the 40 patients (57.5%) had hypocalcemia. The prevalence of vitamin and micronutrient derangements at 6 months was as follows: 34 (18 deficiency and 16 insufficiency) of the 40 patients (85%) had vitamin D deficiency, 31 of the 40 patients (77.5%) had hypocalcemia.
Conclusion: our study shows that LSG is very good bariatric procedure with excellent results on short term follow up regarding body weight reduction, BMI.
