NCT07183137

Brief Summary

This study is designed to understand how bariatric surgery affects patients with metabolic syndrome over both the short and long term. We will track changes in blood pressure and other health indicators for up to 10 years after surgery. The goal is to see whether surgery can provide lasting benefits for controlling blood pressure and improving overall health in patients with metabolic syndrome.

Study Population

The study population consists of adult patients aged 18 to 65 years who were scheduled to undergo bariatric surgery, including laparoscopic Roux-en-Y gastric bypass (LRYGB) or laparoscopic sleeve gastrectomy (LSG), at three participating medical centers in China. Patients were selected based on guideline-based indications for bariatric surgery at the time of recruitment. For the primary analysis, only patients with hypertension were included, defined as meeting at least one of the following criteria: (1) systolic blood pressure ≥140 mmHg and/or diastolic blood pressure ≥90 mmHg; (2) self-reported or physician-diagnosed hypertension; or (3) current use of antihypertensive medications. Patients with coexisting cardiac insufficiency, renal dysfunction, contraindications to surgery or anesthesia, or who declined participation were excluded. Additional exclusions during the data analysis phase included patients who experienced severe postoperative adverse events within 7 days, had fewer tha

You may qualify if:

  • (1) aged 18-65 years; (2) scheduled to undergo bariatric surgery, including laparoscopic Roux-en-Y gastric bypass (LRYGB) or laparoscopic sleeve gastrectomy (LSG); and (3) met the guideline-based indications for surgery at the time of operation.

You may not qualify if:

  • (1) coexisting cardiac insufficiency or renal dysfunction; (2) contraindications to bariatric surgery or anesthesia; and (3) refusal to provide informed consent.
