ABSTRACT
Introduction: 'Phonation' is the physical process by which the vocal folds produce certain sounds. According to laryngology, there are different factors that can affect our larynx (voice box) negatively, such as: Obesity, benign vocal cord lesions, sex hormones, head and neck surgeries and patients who are suffering from health complications recovered from COVID-19 after a prolonged intubation. These factors could show difficulties in voice, airway, and swallowing. Aim: This study aimed to investigate the relationship between obesity and chronic laryngitis in which this inflammation hinders phonation and voice/sound output. This investigation in South Korea using data from Korea National Health and Nutrition Examination Survey (KNHANES) collected during 2008 - 2010. Method: (KNHANES) was a cross-sectional survey of the civilian, noninstitutionalized population of South Korea (n=13,819) aged 19 years or older. Obesity status was measured by using BMI and waist circumference. Conclusions: Obese women in Korea have an elevated risk for developing chronic laryngitis. Chronic laryngitis itself is a misfortune. Chronic laryngitis (CL) causes excess mucus, a sore throat, a persistent dry cough, loss of voice and phonation and difficulty swallowing. Moreover, obese women will suffer from hormonal imbalances that show changes in their voice tones. Elevated estrogen levels cause gastric acid secretion and GERD in women. To help those patients, it is better to shift into a healthy lifestyle, manage their weight by healthy diet and exercises. In this way, a lot of complications will be lessened such as: GERD that is responsible for benign vocal cord lesions possibility. Some women who suffer from chronic laryngitis and turns into cancer decide to do neck surgery. Otolaryngologists stated common side effects from head and neck surgery include temporary or permanent loss of normal voice, impaired speech, and hearing loss.
