Association Between Sarcopenia, Fatigue and Orthostatic Intolerance in Geriatric Patients: A Case Control Study

This study aims to explore the relationship between sarcopenia, fatigue, and orthostatic intolerance in older adults. It will be conducted among geriatric patients attending Ain Shams University Hospitals. Participants aged 65 years and older will be divided into two groups: those with sarcopenia, diagnosed according to the European Working Group on Sarcopenia in Older People 2, and age- and sex-matched controls without sarcopenia. The study will compare levels of fatigue and the presence of orthostatic intolerance between the two groups. The findings are expected to improve understanding of how sarcopenia is associated with fatigue and orthostatic symptoms in the elderly population, which may help guide better clinical assessment and management.
