What this trial studies

This observational study focuses on the comprehensive management of bariatric surgery by integrating various disciplines such as general surgery, endocrinology, nutrition, exercise, and traditional Chinese medicine. It aims to record key health indicators of patients before and after surgery and employs machine learning techniques to predict postoperative complications. The ultimate goal is to enhance precision management and establish a refined diagnosis and treatment system for metabolic weight loss surgery, thereby improving patient outcomes and reducing healthcare burdens.

Who should consider this trial

Good fit: Ideal candidates include individuals with simple obesity or type 2 diabetes who have not achieved adequate control through lifestyle changes or medical treatment.

Not a fit: Patients with non-obese type 1 diabetes or those with significant loss of pancreatic function may not benefit from this study.

Why it matters

Potential benefit: If successful, this study could lead to improved management and outcomes for patients undergoing bariatric surgery.

How similar studies have performed: Other studies have shown success in using integrated approaches for managing bariatric surgery, but this specific methodology may be novel.
