The Relationship Between Bariatric Surgery and Diet Quality: a Systematic Review

Patient adherence to multivitamin supplementation after bariatric surgery: a narrative review

“…In spite of multiple clinical benefits, bariatric surgery can lead to deficiencies in macronutrients and micronutrients as a consequence of reduced intake, changes in eating pattern, food intolerance, gastrointestinal symptoms and malabsorption (3,4) . This is confirmed by the recently published systematic review by Zarshenas et al who found an unbalanced nutritional diet with inadequate protein intake and micronutrients in many included studies (5) .…”

“…However, vitamin deficiencies are quite common after bariatric surgery despite the use of MVS, which can lead to serious long-term complications (3,(11)(12)(13) . Zarshenas et al reported about an inconsistent adherence of MVS intake after bariatric surgery (5) . Many other studies have shown that long-term adherence of bariatric patients to MVS intake is poor (10,(12)(13)(14)(15)(16)(17)(18) .…”

“…However, it is unclear which factors contribute to patient Abbreviations: LRYGB: laparoscopic Roux-en-Y gastric bypass; LSG: Laparoscopic sleeve gastrectomy; MVS: multivitamin supplementation; OAGB/MGB: One Anastomosis/Mini-Gastric Bypass adherence in taking MVS. Zarshenas et al also described that further longer term and more robust studies are needed to assist healthcare professionals in providing nutritional care for bariatric surgery patients (5) .…”

Missing Something? Comparisons of Effectiveness and Outcomes of Bariatric Surgery Procedures and Their Preferred Reporting: Refining the Evidence Base

“…Adherence to post-BS nutritional plans is considered a good prognostic factor for significant WL [15], and WR after BS is associated with poor dietary adherence [17,18]. Recently, a systematic review suggested that BS can reduce energy intake but can result in unbalanced diets, inadequate micronutrient and protein intakes, and excessive fat intake which contribute to WR [23]. Others found that six maladaptive eating behaviors accounted for a highly significant portion of post-RYGB patients' poor self-reported dietary adherence, proposing that research is needed to assess the associations between maladaptive eating behaviors and BS outcomes [23].…”
