Alcohol Allergies: Can They Develop Later in Life?
For those with genetically-caused alcohol intolerance, the most straightforward approach is to avoid alcohol altogether, preventing the onset of symptoms. Because acetaldehyde is toxic and carcinogenic (causing cancer), avoiding alcohol altogether is the only option that medical professionals will recommend. Alcohol intolerance is distinctly different from having a lower tolerance for alcohol’s intoxicating effects, although the two are often confused. Individuals with alcohol intolerance are genetically predisposed to have inadequate amounts of the enzyme needed to metabolize alcohol efficiently. As a result, even a minimal intake of alcohol can lead to noticeable and often severe reactions, distinguishing this condition from the typical experience of over-intoxication.
- If you sit in that group, try to stay well below national guideline limits, eat before and during drinking, and alternate each drink with water or a non alcoholic option.
- If you’re experiencing similar changes after starting a new medication, it might be time to have a chat with your doctor or pharmacist.
Alcohol intolerance and allergies: Symptoms & causes
The symptoms of alcohol intolerance include flushing of the skin on the chest, neck, and face, rapid heart rate, headache, low blood pressure, hives, runny nose, and stomach pain. These symptoms can occur immediately after drinking alcohol and can be unpleasant and uncomfortable. Certain factors can increase the risk of developing an allergy to alcohol later in life. These factors include age, genetic Alcohol Intolerance predisposition, pre-existing health conditions, and excessive alcohol consumption.
Treatment and Medication Options for Alcohol Intolerance
Avoiding alcohol is always the best option for those with alcohol intolerance, as the increased acetaldehyde levels increase your cancer risk. Avoiding alcohol also helps you to avoid the unpleasant symptoms that alcohol intolerance can create. This genetic deficiency results in decreased levels of aldehyde dehydrogenase, the enzyme that breaks acetaldehyde into non-toxic chemicals. Those with normal aldehyde dehydrogenase levels break acetaldehyde down almost instantaneously, while those with ALDH2 deficiency metabolize it quite slowly. This is typically more than just feeling queasy, but severe abdominal cramping and retching that occurs very soon after drinking alcohol.
Support and Awareness
This nausea and vomiting will differ from vomiting that can happen when drinking in that it will be very soon after drinking, occurring suddenly and intensely. While there is no way to treat this condition, your healthcare provider can talk with you about ways to reduce the negative effects of alcohol intolerance. If you have any unpleasant symptoms after drinking alcohol, see your healthcare provider. Your provider can help get to the bottom of your symptoms and recommend the best next steps.
While a blood allergy test can help identify an allergy to certain components in alcoholic beverages, it won’t confirm alcohol intolerance. It’s important to consult with a healthcare provider, who can provide appropriate testing and treatment options based on a detailed medical history and observation of symptoms. It’s important to note that an alcohol allergy is different from an intolerance. While an intolerance is caused by the body’s inability to properly metabolize alcohol, an allergy is caused by an immune system reaction to the proteins found in alcohol.
The Role of Nutrition and Hydration in Detox and Recovery
The increased risk among Asians is attributed to inherited genetic traits that result in the body lacking the proper enzymes to metabolize alcohol’s toxins. As individuals age, their ability to metabolize alcohol decreases due to reduced enzyme activity 4. This decline in enzyme function can contribute to a decrease in alcohol tolerance.
