Symptoms typically start shortly after alcohol consumption, with facial flushing and warmth, headaches and dizziness. In more severe cases, this can escalate to nausea and vomiting, heart palpitations and difficulty with breathing.
Now, there is an at-home DNA test that can reveal if you are one of the unfortunate people who are genetically adverse to booze. The simple cheek swab test detects telltale clues in your DNA, with results sent back to you within 10 working days.
An enzyme called aldehyde dehydrogenase (ALDH) is responsible for eliminating this toxic byproduct. In most people, this enzyme works at clearing away acetaldehyde, but some have a variation in the gene that results in a defective form of the enzyme, causing acetaldehyde to accumulate.
He urges those with this defective enzyme should only drink in small amounts make sure they're washing alcohol down with plenty of water. 'Make sure that you follow a balanced diet, avoid stress and sleep well. When you want to drink alcohol make sure that you are well-hydrated, eat before you drink and, of course, avoid consuming excessive amounts of alcohol.'
