Detailed Description
The aim of the study is to compare the prevalence of sarcopenia and nutritional status between adults older than 65 years who have previously undergone bariatric surgery and patients with obesity but without previous bariatric surgery.
Current sarcopenia will be assessed during a cross-sectional assessment after surgery using the criteria from the European Working Group on Sarcopenia in Older People (EWGSOP).
