What is Alcohol Intolerance?

The primary cause of alcohol intolerance is a genetic deficiency in the aldehyde dehydrogenase 2 (ALDH2) enzyme. This genetic condition means the body struggles to break down alcohol effectively, leading to unpleasant reactions. People of East Asian descent are more likely to inherit this condition.

When ALDH2 levels are low, a harmful substance accumulates, resulting in flushing, an increased heart rate, and headaches. People of East Asian descent often experience a condition called Asian flush” or “Asian glow. This occurs because their bodies cannot process alcohol efficiently.

Causes of Alcohol Intolerance

Alcohol intolerance is primarily because of a genetic issue that hinders the body’s ability to process alcohol effectively. This genetic condition affects the enzyme responsible for breaking down alcohol. Additional factors that may contribute to alcohol intolerance include:

  • Aging: As people age, their liver becomes less effective at breaking down alcohol, increasing their sensitivity to its effects.
  • Medication Interactions: Certain medications interfere with the body’s ability to process alcohol, causing intolerance reactions when people consume alcohol.

Genetic Testing for Alcohol Intolerance

Genetic testing can provide valuable insights into a person’s risk for alcohol intolerance. By analyzing a person’s DNA, healthcare professionals can identify specific genetic variations, particularly in the ALDH2 gene, that influence how the body processes alcohol.

Benefits of Genetic Testing

  • Personalized Insights: Individuals can gain a clearer understanding of their risk for alcohol intolerance, allowing for tailored health recommendations.
  • Informed Decision-Making: Knowing your genetic risks can be a powerful tool for making healthier choices about alcohol consumption.
  • Family History Awareness: Genetic testing can also reveal whether family members may share similar intolerance, encouraging proactive management strategies.

Alcohol Intolerance Reaction

People with alcohol intolerance react quickly to alcohol because their bodies can’t process it properly. This reaction can vary in intensity but is often uncomfortable enough to discourage further drinking.

  • Rapid Onset: Symptoms begin quickly, sometimes within minutes.
  • Visible and Physical Reactions: Flushing, nausea, or rapid heartbeat.
  • Lasting Effects: While temporary, reactions may persist until the alcohol fully leaves the system.
