OBJECTIVE: The present study aims to examine subjectively and objectively the voice changes in bulimia nervosa (BN) patients at different stages of treatment.
METHOD: The study was conducted with a study group including 10 patients followed up with a diagnosis of BN and a control group consisting of 10 healthy participants of a similar age group without eating disorders. The Reflux Symptom Index (RFS) was used for stroboscopic evaluation. The fundamental frequency (F0), jitter, shimmer, and noise-to-harmonics ratio were determined during acoustic voice analysis. Maximum phonation time was analyzed. A subjective evaluation was performed using the Voice Handicap Index-10 (VHI-10).
RESULTS: Jitter, shimmer, VHI-10 score, and RFS values showed a statistically significant difference in the patient and control groups (P < 0.05). The mean values of jitter, shimmer, VHI-10 score, and RFS were higher in the patient group than in the control group. Maximum phonation time did not differ between groups (P > 0.05) Age and F0 (Hz) values showed no statistically significant difference in the patient and control groups (P > 0.05).
CONCLUSIONS: In BN patients, the laryngopharyngeal reflux mechanism causes negative effects on vocal cord examination and acoustic sound analysis parameters, leading to subjective dissatisfaction.
