To report the prevalence of metabolic (dysfunction)-associated fatty liver disease (MAFLD) and elevated liver stiffness among US adults who meet the criteria for bariatric surgery.
Key Findings:
MAFLD affects 37–39% of the general adult US population and ~75% of patients with type 2 diabetes, highlighting a significant public health concern.
The prevalence of severe obesity has increased significantly, contributing to the rise of MAFLD.
Bariatric surgery is effective for achieving significant weight loss and improving liver inflammation and fibrosis.
Interpretation:
The study highlights the high prevalence of MAFLD and elevated liver stiffness in potential bariatric surgery candidates, suggesting an urgent need for better screening and management strategies.
Limitations:
The study is cross-sectional and cannot establish causality, which limits the interpretation of the findings.
Data may not be generalizable to all bariatric surgery candidates due to the specific population sampled.
Conclusion:
Given the rising prevalence of MAFLD and its implications for bariatric surgery candidates, further research and routine screening for liver disease in this population are warranted to improve patient outcomes.
