Quizplus · Accepted Answer

The buildup of acetaldehyde, a toxic substance, causes flushing syndrome. When alcohol is consumed, it is metabolized by the enzyme alcohol dehydrogenase into acetaldehyde, which is then further metabolized by the enzyme acetaldehyde dehydrogenase into a less toxic substance. However, when there is an excess of alcohol consumed, the acetaldehyde accumulates and causes symptoms such as flushing, nausea, and headache.
