The eligible subjects who have given their consent to participate will undergo one of two surgical procedures; sleeve gastrectomy and Roux-en Y gastric bypass.\n\nThe primary objective of this clinical trial is to measure the changes in body weight (kg) and waist circumference (cm) of the enrolled patients at postoperative 1 year. Secondary outcomes are improvement or remission rates of obesity-related co-morbidity (hypertension, type 2 diabetes, dyslipidemia, and sleep apnea), and the change in quality of life. Additionally, postoperative incidences of morbidity and mortality, micronutrient status, body composition, and cost-effectiveness of surgical intervention will be examined.'}, 'eligibilityModule': {'sex': 'ALL', 'stdAges': ['ADULT', 'OLDER_ADULT'], 'maximumAge': '65 Years', 'minimumAge': '20 Years', 'healthyVolunteers': False, 'eligibilityCriteria': 'Inclusion Criteria:\n\n1. body mass index (BMI) ≥ 35 kg/m2 or BMI ≥ 30 kg/m2 with co-morbidities such as hypertension, glucose intolerance, dyslipidemia, and sleep apnea\n2. being suitable for general anesthesia\n3. being able to give informed consent and committed to follow-up\n4.
