Vocal cord polyps are a relatively common otolaryngological ailment. In terms of diet, it is advised not to consume spicy and irritating foods such as chili peppers, Sichuan pepper, and black pepper, as well as foods that are likely to cause allergies. These foods can directly irritate the throat and vocal cords, potentially exacerbating symptoms such as hoarseness and possibly causing throat pain and a sensation of a foreign object in the throat. Patients with vocal cord polyps should visit an otolaryngology clinic after symptoms appear. Routine blood tests and laryngoscopy can help determine the specific cause and extent of the condition, which then facilitates targeted treatment.
