Patients with vocal cord nodules can eat seafood, as it does not exacerbate the condition, nor does it generally interact directly with medications used to treat vocal cord nodules, or affect the treatment outcomes. Therefore, it is generally safe for patients with vocal cord nodules to consume seafood. However, it is advised not to eat spicy and irritating foods, and to avoid smoking and drinking alcohol. These foods or poor lifestyle habits can significantly impact the condition, potentially worsening it. It is necessary to visit an otolaryngologist for standardized treatment and to have regular follow-ups to monitor the treatment effects.
