Vocal cord polyps are benign neoplasms that occur on the free edge of our vocal cords. People with vocal cord polyps should not drink alcohol for several main reasons:

Firstly, alcohol directly irritates the vocal cords, which is a stimulatory effect.

Secondly, after drinking alcohol, blood vessels dilate. The dilation of blood vessels in the vocal cord mucosa leads to vocal cord congestion and aggravated vocal cord edema, which further exacerbates inflammation.

Thirdly, some patients may be allergic to alcohol. An allergic reaction can also cause congestion and increased edema of the vocal cord mucosa, worsening the condition of vocal cord polyps.

Therefore, considering the aforementioned reasons, patients with vocal cord polyps cannot drink alcohol.
