Micronutrient deficiencies (MD) shortly after sleeve gastrectomy (SG) are frequent and patients with obesity often show MD preoperatively. Our aim was to assess whether the correction of MD before SG could play a role in preventing early postoperative MD. Eighty patients (58 females, 22 males) who underwent SG were evaluated retrospectively. Patients were divided according to whether they had received preoperative MD correction (Group A, n = 42; 30 females, 12 males) or not (Group B, n = 38; 28 females, 10 males). Micronutrient status was assessed preoperatively, at 3 and 12-months after SG in both groups. After SG, Group A and Group B patients received the same multivitamin supplement and followed the same diet. Nutrient intake of all patients was evaluated by food frequency questionnaires. Before SG, patients of Group A had no MD, whereas patients of Group B were mostly deficient in vitamin B12 (10.5%, 3 women, 1 man), folate (15.8%, 5 women, 1 man), 25-vitamin D (39.5%, 10 women, 5 men), iron (26.3%, 8 women, 2 men), and zinc (7.9%, 2 women, 1 men). At 3- and 12-month follow-up, no patient in group A had developed new MD, whereas all patients of Group B continued to be deficient in one or more micronutrient, despite systematic postoperative supplementation. No statistical differences (p<0.05) in estimated nutrient intake were observed in either group. Based on our findings, we are able to support the hypothesis that pre-SG correction of MD may be useful in preventing early post-SG MD.

Abstract

Micronutrient deficiencies (MD) shortly after sleeve gastrectomy (SG) are frequent and patients with obesity often show MD preoperatively. Our aim was to assess whether the correction of MD before SG could play a role in preventing early postoperative MD. Eighty patients (58 females, 22 males) who underwent SG were evaluated retrospectively. Patients were divided according to whether they had received preoperative MD correction (Group A, n = 42; 30 females, 12 males) or not (Group B, n = 38; 28 females, 10 males). Micronutrient status was assessed preoperatively, at 3 and 12-months after SG in both groups. After SG, Group A and Group B patients received the same multivitamin supplement and followed the same diet. Nutrient intake of all patients was evaluated by food frequency questionnaires. Before SG, patients of Group A had no MD, whereas patients of Group B were mostly deficient in vitamin B12 (10.5%, 3 women, 1 man), folate (15.8%, 5 women, 1 man), 25-vitamin D (39.5%, 10 women, 5 men), iron (26.3%, 8 women, 2 men), and zinc (7.9%, 2 women, 1 men). At 3- and 12-month follow-up, no patient in group A had developed new MD, whereas all patients of Group B continued to be deficient in one or more micronutrient, despite systematic postoperative supplementation. No statistical differences (p<0.05) in estimated nutrient intake were observed in either group. Based on our findings, we are able to support the hypothesis that pre-SG correction of MD may be useful in preventing early post-SG MD.
