BACKGROUND: Characteristics of bulimia nervosa (BN) and laryngopharyngeal reflux (LPR) and laryngeal and voice disorders that can arise from exposure to gastric acid of the larynx. PURPOSE: To describe, through literature review, the characteristics of LPR and the BN, linking them with laryngeal and voice disorders that can stem from exposure to gastric acid of the larynx, occurring in both conditions. CONCLUSION: BN is characterized by an eating disorder, where there is a mainly psychological compulsive ingestion of large quantities of food, followed by episodes of self-induced vomiting in order to prevent weight gain. LPR consists of a clinical variation of gastro esophageal reflux disease (GERD), in which the retrograde flow of food and stomach acid comes into contact with the larynx and its structures. In common, BN and LPR have this mechanism of regurgitation that may reach the larynx. The signs and symptoms arising from the vocal and laryngeal regurgitation of gastric acid on the larynx are: globus pharynx, dysphonia, hoarseness, dry cough, dysphagia, halitosis, inflammatory lesions on the vocal cords, laryngitis, tonsillitis, swelling and redness and / or posterior glottis of the arytenoids, and the retrocricoid and interarytenoid region, subglottic stenosis, irregularities in the vocal folds mucosa, hypertrophy of the laryngeal mucosa, leukoplakia, carcinoma, laryngospasm, granulomas, contact ulcer, vocal nodules, vocal polyps, diffuse edema, unilateral or fixing bilateral arytenoids, edema, laryngomalacia, stridor and odynophagia
