Abstract

BACKGROUND:

Laparoscopic sleeve gastrectomy (LSG) has become more popular in recent years. The aim of this study was to determine the vitamin and mineral status in patients up to 5 years after LSG and to explore changes that occurred from pre-operatively to 1, 2 and 5 years after surgery.

METHODS:

Data reviewed included age, sex, weight and body mass index (BMI), micronutrient supplements consumed and blood levels of 25 hydroxyvitamin D (25 (OH) D), PTH (parathyroid hormone), ferritin, haemoglobin, folate and vitamin B12, prior to and post-LSG. Data was collated from medical records of morbidly obese patients who had undergone LSG surgery.

RESULTS:

There were a maximum of 336 patients with pre-operative and 1 year after surgery values, n = 272 for 2 years and n = 116 for 5 years after surgery. At 5 years, only 54 % (58/107) of patients reported taking daily multivitamin supplements. Whilst most patients had values within the reference range for haemoglobin, vitamin B12, folate and vitamin D 5 years after LSG, 36 % (34/94) of the patients had serum ferritin below reference value.

CONCLUSION:

This study has highlighted a low micronutrient supplementation adherence. Ferritin levels decreased over time even with multivitamin supplementation. To improve micronutrient guidelines prior to and after LSG, more research, including controlled supplementation studies, are necessary.
