Introduction
Sleeve gastrectomy (SG) is associated with short-term nutritional deficiencies postoperatively. This study evaluates the long-term percentage of excess weight loss (% EWL), and nutritional deficiencies in a single-centre cohort undergoing SG as a primary procedure, with a 6-year follow-up.

Material and methods
From January 2005 to December 2010 the records of 209 patients who underwent laparoscopic SG were retrieved from a computer database for analysis. Sixty out of the 209 paients completed follow-ups for 6 years.

Results
Median % EWL at 1, 2, 3, 4, 5, and 6 years postoperatively was 80.9%, 79.1%, 73.8%, 71.8%, 71.5%, and 64.9%, respectively. Prior to surgery, 17.2% had anaemia. Deficiencies of iron, ferritin, folic acid, vitamin B12, magnesium, and phosphorus were 22%, 5.3%, 1.4%, 3.8%, 29.7%, and 5.3%, respectively. Six years post-surgery, deficiencies of haemoglobin, ferritin, and B12 worsened (36.7%, 43.3%, and 11.7%, p = 0.001, p < 0.001, p = 0.019, respectively), whereas there was no significant difference in deficiencies of iron, folic acid, magnesium, and phosphorus (25%, 1.7%, 20%, and 3%, p = 0.625, p = 0.896, p = 0.139, p = 0.539, respectively). There was elevated PTH before and 6 years after surgery (2.9% and 1.7%, p = 0.606).

Conclusions
This retrospective study shows that laparoscopic sleeve gastrectomy had a considerable effect on specific nutritional deficiencies in our patients at 6 years post-surgery. Knowledge of micronutrient deficiencies in these patients is beneficial for both prevention and management of nutritional complications associated with SG with the administration of oral nutritional supplementation according to the patient’s needs.
