What this trial studies

This study evaluates the five-year outcomes of patients who undergo laparoscopic gastric sleeve surgery for morbid obesity at Tartu University Hospital. It follows patients prospectively to assess weight loss, obesity-related comorbidities, and the risk factors for postoperative nutritional deficiencies. Follow-up visits are scheduled at 3 months, 1 year, and 5 years after the surgery to gather comprehensive data on patient progress and health outcomes.

Good fit: Ideal candidates for this study are individuals with a BMI greater than 40, or greater than 35 with obesity-related comorbidities.

Not a fit: Patients who do not meet the criteria for bariatric surgery will not benefit from this study.

Why it matters

Potential benefit: If successful, this study could provide valuable insights into the long-term effectiveness and safety of laparoscopic gastric sleeve surgery for weight loss and management of obesity-related health issues.

How similar studies have performed: Other studies have shown positive outcomes with similar approaches in evaluating long-term results of bariatric surgeries, indicating that this methodology is supported by existing evidence.
