Vestibular and balance changes before and after sleeve gastrectomy
Evaluation of the Effect of Bariatric Surgery on the Vestibular System in Obese Patients.
This study will see if vestibular (balance) function improves in adults having sleeve gastrectomy for severe obesity by testing them before surgery and at one and six months after surgery.

What this trial studies
This is an observational study enrolling Turkish-speaking adults aged 18–60 with BMI ≥40 who are scheduled for bariatric sleeve gastrectomy. Participants will have baseline history and BMI recorded, then undergo vestibular and balance testing including video head impulse test (vHIT), static posturography, Berg Balance Scale, SF-12 quality of life, and an activity-specific balance confidence measure. The same battery will be repeated at 1 month and 6 months after surgery to track short- and mid-term changes associated with weight loss. People with prior vestibular diagnoses, neurological disorders, or significant joint/muscle/walking problems are excluded, and no experimental interventions are assigned.
Who should consider this trial
Good fit: Ideal candidates are Turkish-speaking adults aged 18–60 with BMI ≥40 who are eligible for sleeve gastrectomy and have no prior vestibular or major mobility disorders.
Not a fit: People with preexisting vestibulopathy, neurological disease, significant joint or muscle problems, non-Turkish speakers, or those outside the age/BMI range are unlikely to benefit from this study's findings.
Why it matters
Potential benefit: If findings show improvement after weight loss, clinicians could better predict balance recovery and tailor fall-prevention or rehabilitation plans after bariatric surgery.
How similar studies have performed: Prior research indicates obesity can impair vestibular function, but longitudinal data on vestibular recovery after bariatric surgery are limited, so this approach builds on partial prior evidence rather than being entirely novel.
