Overview

Introduction:
Experience from the past twenty years shows that surgical treatment is the most effective treatment for severe obesity. Changes in patients’ behaviour are some of the most striking effects of bariatric surgery.

Design:
The aim of this study was to assess the influence of sleeve gastrectomy on the body weight and eating habits of patients 3 and 6 months after surgery.

Methods:
A cohort of 44 patients (35 women and 9 men) underwent body weight, height, waist and hip, body fat (Dual X-ray Absorptiometry – DXA) measurement, and their BMI was calculated. Dietary habits were assessed by a questionnaire filled in by 19 persons (15 women and 4 men). A frequency questionnaire was used. The consumption frequency of selected food groups was measured, as well.

Results:
Six months after surgery, an average weight reduction of 27.3 kg (p < 0.001) was found. BMI decreased by 9.7 kg/m² (p < 0.001), and body fat decreased by 17.6 kg (p < 0.001). Patients reported reduced appetite (p < 0.001), greater regularity of meals (p < 0.001), more servings per day (p = 0.003) and paid more attention to diet than before surgery (p = 0.018). They eat less fatty meat, sausages with high fat and white bread, while they eat more fish (p = 0.008 to 0.049).

Conclusion:
Sleeve gastrectomy and follow-up by a nutritional therapist led to an improvement in the eating habits of some patients six months after surgery. For a further assessment of the effectiveness of the treatment, the group of patients will be followed up for two years.
