Nutritional deficits are common among candidates for bariatric surgery, and follow-up of nutritional status is critically needed for post-surgery healthcare management. This observational prospective study was conducted at King Khalid University Hospital in Riyadh. Samples were collected pre- and post-laparoscopic sleeve gastrectomy (LSG), with the visit intervals divided into four visits: pre-surgery (0M), 3 months (3M), 6 months (6M) and 12 months (12M). Food intake and eating patterns significantly changed during the first year (<jats:italic>P<\/jats:italic> &lt; 0\u00b7001). The mean energy intake at 3M post-surgery was 738\u00b73 kcal, significantly lower than the pre-surgery energy intake of 2059 kcal. Then, it increased gradually at 6M and 12M to reach 1069 kcal (<jats:italic>P<\/jats:italic> &lt; 0\u00b700). The intake of Fe, vitamin B<jats:sub>12<\/jats:sub> and vitamin D was below the dietary reference intake recommendations, as indicated by the 24-hour dietary recall. The prevalence of 25 (OH) vitamin D deficiency improved significantly from pre- to post-surgery (<jats:italic>P<\/jats:italic> &lt; 0\u00b7001). Vitamin B<jats:sub>12<\/jats:sub> deficiency was less reported pre-LSG and improved steadily towards a sufficient post-surgery status. However, 35\u00b77 % of participants were deficient in Fe status, with 28\u00b76% being female at higher levels than males. While protein supplementation decreased significantly over the 12M follow-up, the use of vitamin supplements dramatically increased at 3 and 6M before declining at 12M. Fe and vitamin B<jats:sub>12<\/jats:sub> were the most popular supplements after vitamin D. This study confirms the necessity for individualised dietary plans and close monitoring of candidates\u2019 nutritional status before and after bariatric surgery.<\/jats:p>","DOI":"10.1017\/s0007114524002460","type":"journal-article","created":{"date-parts":[[2024,11,8]],"date-time":"2024-11-08T09:08:41Z","timestamp":1731056921000},"page":"1454-1465","update-policy":"https:\/\/doi.org\/10.1017\/policypage","source":"Crossref","is-referenced-by-count":0,"title":["Nutritional status of Saudi obese patients undergoing laparoscopic sleeve gastrectomy, one-year follow-up study"],"prefix":"10.1017","volume":"132","author":[{"ORCID":"https:\/\/orcid.org\/0000-0003-2223-9154","authenticated-orcid":false,"given":"Seham J.","family":"Alqahtani","sequence":"first","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Hanan A.","family":"Alfawaz","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Fuad A.","family":"Awwad","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Ahmad T.","family":"Almnaizel","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Anwar","family":"Alotaibi","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Adnan S.","family":"Bajaber","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Afaf","family":"El-Ansary","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"56","published-online":{"date-parts":[[2024,11,8]]},"reference":[{"key":"S0007114524002460_ref26","doi-asserted-by":"publisher","DOI":"10.1007\/s40618-020-01439-7"},{"key":"S0007114524002460_ref1","doi-asserted-by":"publisher","DOI":"10.1159\/000511023"},{"key":"S0007114524002460_ref51","doi-asserted-by":"publisher","DOI":"10.1001\/jama.2017.20897"},{"key":"S0007114524002460_ref12","doi-asserted-by":"publisher","DOI":"10.1007\/s11695-020-05207-7"},{"key":"S0007114524002460_ref13","doi-asserted-by":"publisher","DOI":"10.1007\/s11695-022-06256-w"},{"key":"S0007114524002460_ref44","doi-asserted-by":"publisher","DOI":"10.1007\/s11695-018-3225-9"},{"volume-title":"Waist Circumference and Waist\u2013Hip Ratio: Report of a WHO Expert Consultation","year":"2011","key":"S0007114524002460_ref20"},{"key":"S0007114524002460_ref46","doi-asserted-by":"publisher","DOI":"10.1007\/s11695-009-9919-2"},{"key":"S0007114524002460_ref31","doi-asserted-by":"publisher","DOI":"10.1007\/s11695-016-2211-3"},{"key":"S0007114524002460_ref56","doi-asserted-by":"publisher","DOI":"10.3390\/nu14010082"},{"key":"S0007114524002460_ref2","doi-asserted-by":"publisher","DOI":"10.1016\/j.psc.2011.08.005"},{"key":"S0007114524002460_ref33","doi-asserted-by":"publisher","DOI":"10.1177\/0884533614552850"},{"key":"S0007114524002460_ref32","doi-asserted-by":"publisher","DOI":"10.1007\/s11695-012-0827-5"},{"key":"S0007114524002460_ref4","unstructured":"4.
