About this study
Official title: Examining the Relationship Between Eating Disorders, Anthropometric Characteristics, and Physical Activity After Bariatric Surgery: A 2-Year Longitudinal Study
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.
Read the detailed description
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.

| Study group | Role | What they receive |
|---|---|---|
| Bariatric Surgery Group | Individuals Undergone Bariatric Surgery |
What is being measured
The primary outcome is the main question the study is designed to answer.
Structural Sociodemographic survey
to get information about physical activity duration and other secondary diseases
Measured: 2 year
Body Mass Index
It will be calculated as weight in kilograms divided by height in meters squared
Measured: 2 year
Eating Disorder Examination Questionnaire
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).
Measured: 2 year
