Relationship Between Eating Disorders, Anthropometric Characteristics, and Physical Activity After Bariatric Surgery

In individuals diagnosed with obesity, the traditional treatment method involves changing and regulating dietary habits and increasing physical activity levels. When these measures prove insufficient, pharmacological interventions are used.

When exercise programs conducted after bariatric surgery are compared to weight loss achieved through surgery alone, it is believed that physical activity after bariatric surgery is an effective approach to improving metabolic health.

Gastric leptin level indicates the level of leptin hormone found in stomach tissue. Leptin is a hormone produced by adipose tissue in the body and plays a role in energy balance. It generally controls appetite by reducing feelings of hunger and helps regulate body weight by increasing energy expenditure.

This study aims to examine the relationship between gastric leptin levels, eating disorders, and physical activity after bariatric surgery.

About this study

n individuals diagnosed with obesity, the traditional treatment method involves changing and regulating dietary habits and increasing physical activity levels. When these measures prove insufficient, pharmacological interventions are used. However, in 90% of individuals diagnosed with obesity, these treatments have been found to be ineffective, failing to achieve the desired results. It has been reported that weight loss of 5-10% over a five-year period is difficult to achieve. When all these methods are evaluated, it has been reported that bariatric surgery has been a successful technique in improving the health of individuals diagnosed with obesity in recent years. When a technique combining different methods and approaches, such as calorie restriction, physical activity, and behavioral changes in individuals, is attempted, it has been reported that the weight gained in the long term is regained, and the individual is able to perform their physical abilities to a large extent. When exercise programs conducted after bariatric surgery are compared to weight loss achieved through surgery alone, it is believed that physical activity after bariatric surgery is an effective approach to improving metabolic health.

Gastric leptin level indicates the level of leptin hormone found in stomach tissue. Leptin is a hormone produced by adipose tissue in the body and plays a role in energy balance.

Treatment and study plan

Primary outcomes

  1. Structural Sociodemographic survey

    Time frame: 2 year

    to get information about physical activity duration and other secondary diseases

  2. Body Mass Index

    Time frame: 2 year

    It will be calculated as weight in kilograms divided by height in meters squared

  3. Eating Disorder Examination Questionnaire

    Time frame: 2 year

    Eating Disorder Examination Questionnaire (EDE-Q). The EDE-Q consists of four subscales: Restraint, Eating Concerns, Weight Concerns, and Shape Concerns. Each item is rated on a 7-point Likert scale ranging from 0 to 6, with higher scores indicating greater severity of eating disorder symptoms. Subscale scores are calculated as the mean of relevant items, and the Global score is the average of the four subscales. Possible range for each subscale and the global score: 0 (no symptoms) to 6 (highest symptom severity).
