Hello, mouth breathing during sleep primarily occurs because the patient is unable to obtain sufficient oxygen through the nasal airway while sleeping and therefore resorts to oral breathing to compensate. This phenomenon is typically caused by nasal obstruction. Conditions such as rhinitis or nasal polyps can impair nasal airflow during sleep, leading the patient to breathe through the mouth. We hope this information is helpful to you. Wishing you a pleasant life!
