Summary
The goal of this observational cross-sectional study is to evaluate the relationships between the Dietary Inflammatory Index (DII), systemic inflammatory markers, and gastrointestinal symptoms in adults aged 18-65 who have undergone bariatric surgery. The main questions it aims to answer are: Does the inflammatory potential of the diet affect systemic inflammation levels (such as SII, CRP, and WBC) in the post-operative period? Is there an association between the DII score and gastrointestinal symptoms (e.g., bloating, gas, abdominal pain)? Participants who are at least three months post-bariatric surgery will provide dietary intake data to calculate DII scores, undergo blood tests to measure inflammatory markers, and complete assessments regarding their gastrointestinal symptoms.
