Hello, I'm an expert in medical terminology and conditions. I can help explain what a "drinker's nose" is.

A drinker's nose, also known as rhinophyma, is a red, bulbous, and enlarged nose that can develop in people who have been heavy consumers of alcohol over a long period of time. It's a condition that is more common in men and is characterized by the thickening of the skin on the nose, which can cause it to become disfigured.

The exact cause of rhinophyma is not entirely understood, but it is believed to be related to the combination of alcohol consumption, exposure to the sun, and possibly a genetic predisposition. The skin changes are thought to be due to the dilation of blood vessels and the thickening of the sebaceous glands, which produce oil.

Here's the translation in Chinese:

酒糟鼻的确切原因尚不完全清楚，但人们认为它与饮酒、日晒暴露以及可能的遗传倾向有关。皮肤变化被认为是由于血管扩张和皮脂腺增厚所致，皮脂腺是产生油脂的腺体。
