A deficiency or inactivity of ALDH2 leads to the accumulation of acetaldehyde, triggering various intolerance symptoms. Other factors, such as certain medications or health conditions, can also interfere with the normal function of ALDH2, causing intolerance symptoms or mimicking intolerance reactions. It is important to distinguish between alcohol allergy and alcohol intolerance, as the two terms are often mistakenly used interchangeably. Alcohol allergy is an immune system response to certain ingredients in alcoholic beverages, not to the alcohol itself.

What causes alcohol intolerance?

A compromised liver struggles to process alcohol efficiently, leading to adverse reactions after consumption. alcohol intolerance Alcohol intolerance, on the other hand, usually results in symptoms like facial redness or flushing, rapid heart rate, headache, low blood pressure, and gastrointestinal discomfort. These symptoms are consistent across different types of alcoholic beverages, whether beer, wine, or spirits. Taking antihistamines regularly before drinking could also cause your body to build up a tolerance to the medicines. Your judgment may be impaired and you may continue to drink even when your body is trying to tell you to stop. Talk with your doctor before taking any medications to help prevent allergic symptoms from alcohol.

• The sudden development of alcohol intolerance is a common early symptom of CFS.
• People who experience low tolerance can continue to consume alcohol as long as they know their limits and do not exceed the recommended units per week – around 14 units per week for men and women.

Recognizing Immediate Symptoms of Alcohol Intolerance

True alcohol allergy is thought to be rare, while alcohol intolerance is more common. Some people may incorrectly assume they are allergic to alcohol, when in fact they are actually reacting to other components of alcoholic drinks. Symptoms of an alcohol allergy include rashes, itchiness, swelling and severe stomach cramps.

Can you treat alcohol intolerance?

It’s essential for individuals with alcohol intolerance to be aware of these risks and to consider lifestyle changes or seek medical treatment to mitigate them. Some alcoholic beverages, particularly those high in histamine like red wine, are more likely to trigger these symptoms. Understanding and recognizing these symptoms is crucial for those who experience adverse reactions to alcohol. Avoidance of alcohol is the primary way to prevent the onset of these symptoms, as there is no cure for alcohol intolerance.

While there is no cure for this condition, avoiding alcohol helps you stay symptom-free. Even if you only have mild symptoms of alcohol intolerance, you should avoid alcohol. Research has shown that some people with mild symptoms of intolerance can get used to the symptoms of excess acetaldehyde in their bodies. However, acetaldehyde is still highly toxic and can significantly increase the risk of cancer.

• You need to get to the nearest A&E department as this can be a life-threatening medical emergency.
• Lifestyle changes, coping strategies development, and support systems are essential components of managing alcohol intolerance and preventing complications.
• If you experience symptoms no matter what type of alcohol you drink, it’s more likely that you have alcohol intolerance.

Approximately 30 to 50 percent of people in this region have an ALDH2 deficiency and are more likely to experience symptoms such as flushing. In addition to this, studies have identified a link between alcohol consumption and an increased risk of certain cancers. Research suggests that the more alcohol a person consumes, or the more frequently it is consumed, raises their likelihood of developing cancers such as breast, head and neck, oesophageal and more. People who experience low tolerance can continue to consume alcohol as long as they know their limits and do not exceed the recommended units per week – around 14 units per week for men and women. Those with alcohol intolerance should try to limit or abstain from alcohol consumption entirely.

Reasons for low tolerance can include lower body weight, genetics, overall health, and the body not being used to metabolizing alcohol. Keep in mind that not being able to stomach alcohol like you used to is not the same thing as having an allergy to alcohol. With an allergy, the body’s immune system fights the substance, as it perceives it as a threat. When it comes to an intolerance, the body simply isn’t up to the task of breaking it down. By employing these strategies, individuals with alcohol intolerance can maintain an active social life while managing their condition.
