BACKGROUND: One of the most effective surgeries for sustainable weight loss in morbidly obese patients is laparoscopic sleeve gastrectomy (LSG). The present study aimed to assess the adherence of LSG patients with respect to following post‐operative dietary requirements and micronutrient supplementation, as well as to investigate their perceived barriers in achieving optimal adherence. METHODS: Retrospective data analysis was performed (3, 6, 9 and 12 months after LSG) using the medical records of 96 morbidly obese patients who had undergone LSG at our institution during 2011–2013. Data collected from patient records were: adherence to prescribed diet; adherence to prescribed consumption of fruit, vegetables, legumes and cereals; use of prescribed micronutrient supplements; and barriers to diet and micronutrient therapy adherence. Data were analysed using spss, version 14.0 (SPSS Inc., Chicago, IL, USA). RESULTS: At 3, 6, 9 and 12 months post‐LSG, the rates of patient non‐adherence to a prescribed diet were 39%, 45%, 51% and 74%, respectively. In particular, there was a low consumption of fruit, vegetables, legumes and cereals compared to the post‐surgery prescription. In addition, the rates of patient non‐adherence to prescribed micronutrient supplements at 3, 6, 9 and 12 months post‐LSG were 43%, 51%, 59% and 67%, respectively. The main reasons for patient non‐adherence to diet were poor self‐discipline (72%) and poor family support (11%) whereas difficulty swallowing pills or capsules (61%) and cost (20%) were reported as the main barriers to post‐LSG adherence. CONCLUSIONS: Morbidly obese patients who have undergone LSG do not follow exactly the post‐operative dietary guidelines, including micronutrient therapy.
