“…Our ®nding of mean dietary iron intakes below RDI throughout the study is consistent with the results of several other authors who have reported mean iron intakes below RDI in both the early postoperative period 3,4,6 (where reduced levels of micronutrient carrier proteins may contribute) and the late 5,6 postoperative period. Mean zinc intake was`50% RDI at 12 months.…”

“…While it is not surprising that short-term studies have shown that the intakes of many nutrients are below the recommended dietary intake (RDI) in the early postoperative period, 3,4 it is of concern that several small long-term studies indicate that the intake of a number of important nutrients may remain below the RDI at 1±2 years postoperatively. 5,6 It is, however, unclear from these studies what level of dietary advice, if any, was given to subjects preoperatively or at follow-up. Nutritional supplementation is increasingly being advised for all patients who undergo gastric restrictive surgery, 4,6,7 but details of compliance are often not recorded or reported.…”

“…Although this study did not determine dietary folate intake, due to lack of Australian food composition data, the results may be due to low intake, as others have reported folate intakes to be below RDI in both early and late postoperative periods. 3,5,6,16 Vitamin B 12 values in the reference range may have been expected, as the body has considerable B 12 stores and longer followup would be needed to assess whether de®ciency develops. Vitamin B 12 de®ciency has been reported after gastric bypass surgery, but is uncommon after gastric reduction surgery.…”

Nutritional consequences of modified vertical gastroplasty in obese subjects

BACKGROUND: Gastroplasty results in a considerable reduction in food intake and dramatic weight loss. This is likely to have a nutritional impact, although it is expected that this may be minimised by good advice and supplement use. METHODS: Twenty six obese subjects were studied in detail before and after modi®ed long vertical gastroplasty (MLVG), in a setting where comprehensive nutritional advice on symptom avoidance was readily available and multivitamin supplements advised. Nutritional intake and anthropometry were measured preoperatively and at 2, 5 (n 22) and 12 months (n 11) postoperatively. RESULTS: Mean weight loss was 13%, 22% and 31% of initial body weight at the respective time points. Energy intake (EI) was signi®cantly reduced postoperatively, with the mean protein intake being only 40 gad. At 2 months, mean intakes of iron, calcium and zinc from food were 40%, 71% and 39%, respectively, of the Australian recommended dietary intake (RDI), and iron and zinc intake remained below half the RDI at 5 months. Only regular adherence to the vitaminamineral supplement, brought iron and calcium intakes close to RDI, but zinc remained low. Haemoglobin and serum ferritin concentrations did not alter signi®cantly and remained within the reference range, but serum folate fell signi®cantly between 5 months and 12 months. By 5 months, 60% of subjects never regurgitated or regurgitated less than once a week. Fresh bread was the least tolerated food. Frequency of regurgitation was not correlated with adequacy of nutrient intake. CONCLUSIONS: The results emphasise the need for regular follow-up of MLVG patients, and nutritional advice which includes diet quality as well as symptom management, and regular intake of the vitaminamineral supplement for at least a year postoperatively. Low protein intakes, however, remain of potential long-term concern.

“…Although effective as a weight loss procedure, concern has been raised regarding the possibility that gastroplasty may have a nutritional cost (6,7,25,26), particularly in the early postoperative phase when body weight loss is typically the most drastic (13). Recent interest has focused on the relationship between elevated circulating homocysteine concentrations and atherosclerotic and thrombotic vascular diseases (8).…”

Objective To investigate whether the increased homocysteine levels occur in the first 6 months postoperatively, when nutritional intake is the most inadequate and weight reduction is the most drastic. Patients and Methods Fasting glucose, insulin, lipoprotein, homocysteine, folic acid and vitamin B12 levels and oral glucose tolerance test (OGTT)were determined in 12 morbidly obese subjects (3 menand 9 womenwith a mean age of 31±3 years, mean±SEM) before, 6 and 12 months after banded gastroplasty.Results Gastroplasty resulted in significant weight loss, from 120±6 to 92±6 and 88±7 kgs, 6 and 12 months postoperatively (all p<0.001). Fasting plasma insulin and triglyceride concentrations, the ratio of total cholesterol to HDL cholesterol, glucose and insulin responses to OGTT,and the degree of insulin resistance as expressed by the Homeostasis model index decreased significantly (p<0.05-0.001) following gastroplasty. Fasting plasma homocysteine concentrations increased from 10.2±0.8 to 12.1±0.6 at 6 months (p=0.036) and 12.0±1.2 [imo\/l at 12 months (p=0.040), respectively. Pooled plasma homocysteine levels were negatively correlated with serum folate concentrations (r=-0.42, p=0.013). However, serum folate and vitamin B12 levels did not change after gastroplasty, nor did the relation between the loss of body weight and increase in homocysteine levels.Conclusion Weobserved that elevated circulating homocysteine levels occurred as early as 6 months after gastroplasty despite improvement in carbohydrate and lipoprotein metabolism in morbidly obese Chinese subjects.

“…Caloric intake often increases significantly during the postoperative course. 8,[14][15][16][17][18][19] In the Swedish Obese Subjects trial, 8 surgery patients consumed approximately 2900 kcal/ d prior to surgery. Their intake decreased to approximately 1500 kcal/d 6 months after surgery, but increased to approximately 2000 kcal/d 10 years later, when patients had regained approximately 10% of their maximum weight loss.…”

Background-Despite the significant weight losses and dramatic improvements in comorbidities associated with bariatric surgery, a significant minority of patients appear to experience suboptimal weight losses. The reasons for this are not well understood, but often attributed to preoperative psychosocial characteristics and/or eating behaviors as well as poor adherence to the recommended postoperative diet.
