Quality of Life 10 Years After Bariatric Surgery

Importance: Improvement of the QoL after bariatric surgery is an important outcome of the treatment. The investigators believe that assessment of distant QoL results, could provide new insight into effectiveness of most popular bariatric procedures.

Objective: The investigators aim to analyze the bariatric surgery effect on the long term QoL, considering the type of surgery.

Design: A cohort study including patients undergoing bariatric surgery. Setting: One academic referral center. Exposures: Patients undergo Laparoscopic Sleeve Gastrectomy or Laparoscopic Roux-en-Y Gastric Bypass . Surgical technique is standardized and consistent in the whole study group.

Main Outcomes and Measures: The main outcome is the change of QoL after bariatric surgery. It is assessed in three different time points: pre-surgery, first follow up (1 year after surgery) and second follow-up (10 years after surgery). The investigators use two licensed and standardized questionnaires: (Short Form Health Survey) and MA-QoLQII (Moorehead-Ardelt Quality of Life Questionnaire II).
