"50 adult patients suffering from severe or morbid obesity (BMI ≥ 35 kg/m2 in the presence of comorbidities and BMI ≥ 40 kg/m2, respectively), male and female, candidates for bariatric surgery (Sleeve Gastrectomy and Roux-en-Y Gastric Bypass).~Two timepoints: T0 (pre-hospitalization) and T1 (follow-up 12 months +/- 1 month).~Expected assessments at T0 and T1:~* Blood chemistry tests to monitor metabolic markers involved in dietary and metabolic changes.~* Bone densitometry for body composition analysis (DEXA).~* Analysis of pre-intervention walking and the ability to recover motor activity after bariatric surgery using gait analysis."
