What happens when you drink white wine on an empty stomach depends on the amount of white wine you drink. If the amount of liquor is relatively small, around one or two taels, there are generally no other problems. If you have liver function damage or stomach ulcer or erosion, drinking liquor on an empty stomach can easily lead to damage to the local mucosa, erosion, or even an increase in ulcers, leading to ulcerative haemorrhage. Those who have liver function damage also need to observe changes in liver function, and some may lead to acute liver failure. Of course, this happens only if the amount of alcohol consumed is high and the liver is relatively deficient in acetaldehyde dehydrogenase, the enzyme that breaks down alcohol, is prone to this symptom. Therefore, it is not recommended to drink white wine on an empty stomach, and it is best to drink as little as possible.
