Purpose: Dysphagia is a chronic health condition that causes impairment of eating and drinking functions. It occurs in various diseases such as stroke, neurodegenerative disease, brain tumor, and head and neck cancer, and can also occur during the normal aging process. Current concept: As patients experience symptoms of dysphagia, they no longer feel the pleasure of eating, depression and anxiety increase, and self-esteem decreases. Prolonged loss of appetite can lead to malnutrition, which can lead to death due to serious complications such as aspiration pneumonia and airway obstruction. Dysphagia reduces quality of life by affecting basic activities of daily living, limitations in social life, nutritional deficiencies, and mood disorders. Conclusion: Accordingly, I plan to conduct a literature review on the quality of life of patients with dysphagia. First, to determine the relationship between quality of life and sociodemographic, physical health, and mental health characteristics of patients with dysphagia. I also aim to review quality of life measurement tools and intervention programs for patients with dysphagia.
