The effect of bariatric surgery on dietary Behaviour, dietary recommendation Adherence, and micronutrient deficiencies one year after surgery.

Bariatric surgery (BS) is associated with vitamin and mineral deficiencies, which might be augmented by low adherence to dietary guidelines and inappropriate dietary behaviours. The aim of this study was to determine the influence of BS on eating behaviour, prevalence of nutrient deficiency, level of commitment to diet, and lifestyle recommendations one-year post-BS. A cross-sectional study was conducted among adult patients who underwent BS in 2019 and had follow-up for a year. Age, gender, and clinical data were collected from the hospital system and other information was obtained from questionnaires during phone interviews. A total of 160 patients participated in the study. At 12 months, a significant increase from the baseline values in plasma levels of vitamin B12, folate, vitamin D, iron, corrected calcium, albumin, CRP, and MCV, as well as a significant decrease in BMI was observed. Adherence to dietary and lifestyle recommendations was moderate to high. Emotional, and restrained eating behaviours were moderate with 64.4%, and 77.5%, respectively. External eating was low at 58.1%. The study concluded that pre-and post-bariatric surgery nutrients should be closely monitored.

Factors influencing body weight one year after bariatric surgery.

The significant outcome of bariatric surgery (BS) is weight loss, which may be affected by many factors, such as initial body weight before surgery, sex, and dietary intake. Moreover, rapid weight loss is associated with an increased incidence of postsurgical cholelithiasis. To investigate the observed weight loss outcomes during the first year after BS, we investigated the factors that may influence weight loss and to detect the efficacy of prophylactic ursodeoxycholic acid against gallstone formation. This was a retrospective cohort study of all patients with morbid obesity who underwent BS in the hospital and completed a 1-year follow up. Patients with a previous BS or a history of cholecystectomy before BS were excluded. Data were extracted from the medical records at multiple postoperative intervals. There was significant weight loss in terms of percentage of excess weight loss and reduction in body mass index postoperative. A significant correlation was found between the percent of excess weight loss and age, initial body mass index, and initial weight, but there was no significant correlation with sex or type of surgery. The incidence of postoperative cholecystectomy is almost negligible. A significant association was found between age and weight loss after BS. ursodeoxycholic acid is an effective prophylaxis to decrease the incidence of cholecystectomy after BS.

Effect of Bariatric Surgery on Metabolic Syndrome, Framingham Risk Scores and Thyroid Function during One-Year Follow-Up: A Saudi Retrospective Study.

Bariatric surgery (BS) has been demonstrated to achieve sustained weight loss with significant metabolic improvement, including a reduction in cardiovascular disease and diabetes. The aim of this retrospective study is to measure the effect of BS on the Framingham risk score (FRS) and metabolic syndrome (MetS) among patients who underwent bariatric surgery. Additionally, we determine the effect of BS on thyroid-stimulating hormone (TSH) among euthyroid obese patients. A retrospective follow-up study was conducted at King Abdullah Medical City, Makkah, Saudi Arabia. A total of 160 patients underwent BS and completed one-year follow-up visits. Medical history, anthropometric, biochemical, and hormonal parameters were evaluated at baseline and 3−12 months after BS. The International Diabetes Federation (IDF) criteria were used to diagnose MetS. There was a significant decrease in systolic blood pressure (SBP), diastolic blood pressure (DBP), glycated hemoglobin (Hba1c), TSH, low-density lipoprotein (LDL), triglycerides, and total cholesterol (p < 0.001). A significant decrease was seen in MetS, BMI, FRS, SBP, DBP, Hba1c, LDL, triglycerides, cholesterol, and liver enzymes, with a significant increase in high-density lipoprotein levels 12 months postoperatively (p < 0.001). At 12 months, the prevalence of MetS, DM, and HTN and the FRS significantly decreased from 72.5%, 43.1%, 78.1%, and 11.4 to 16.3%, 9.4%, 22.5%, and 5.4, respectively. In addition to achieving substantial weight loss, BS improves MetS prevalence and cardiovascular risk profiles.
