Power through the workday, dominate meetings, crush deadlines – it’s all in a day’s work for high-achieving executives. But what happens when your usual after-work drink starts leaving you feeling worse than ever?

For some high-performing individuals, their bodies are no longer tolerating alcohol the way they used to. This can be frustrating, leaving you wondering: why can’t I drink alcohol anymore without feeling sick?

Key Takeaways:

  • As you get older, your bodies produce fewer enzymes needed to break down alcohol 
  • Women tend to be more sensitive to alcohol than men, especially as they age
  • Treating alcoholism involves strategies such as an Alcohol-Free program and lifestyle adjustments

How Alcohol Affects the Body

Alcohol, once ingested, undergoes a complex breakdown process in the body.

Initially, enzymes such as alcohol dehydrogenase (ADH) convert ethanol into acetaldehyde. It’s a toxic compound and a known carcinogen. This acetaldehyde is then transformed into acetate by aldehyde dehydrogenase (ALDH). Genetic and environmental factors dictate the individual’s alcohol tolerance.

From the first sip, alcohol begins to exert its effects, starting with a warm buzz. It potentially leads to more severe reactions like drowsiness, euphoria, or impaired coordination. These immediate reactions can include mood changes and physical symptoms.

The severity and onset of these effects depend on several factors. These include the quantity of alcohol consumed, drinking speed, and individual metabolic response.

Symptoms of Alcohol Intolerance

Have you noticed that your body’s response to alcohol has changed over time? Perhaps a glass of wine or a few beers that used to leave you feeling relaxed and sociable now triggers unpleasant symptoms.

If so, you may be experiencing the frustrating effects of alcohol intolerance. Your body becomes alcohol intolerant when it lacks the enzymes to process the toxins, according to Mayo Clinic. Having an alcohol allergy is not the same as this condition, which might make drinking difficult.

The symptoms of alcohol intolerance can range from mild to severe, and may include:

  • Flushed or reddened skin
  • Nasal congestion or runny nose
  • Headaches
  • Nausea and vomiting
  • Irregular heartbeat
  • Low blood pressure
  • Fatigue

Prevention is key to alcohol intolerance. You may lose your general health and well-being as a high-achieving person if you ignore the problem.

Alcohol Intolerance vs. Alcoholism

The incapacity to metabolize and absorb alcohol is a sign of alcohol intolerance, a physical condition. Unpleasant symptoms follow from this.

In contrast, alcoholism is a chronic condition that recurs and is known as an obsessive urge to drink alcohol. This is despite the detrimental effects it could have on a person’s life.

It might be more difficult to drink in moderation when one has alcohol intolerance. However, the two conditions are not mutually exclusive. Even those who are alcohol intolerant may get alcohol abuse. So, uncomfortable symptoms associated with an intolerance may also be present in alcoholism.

When it comes to helping those with alcohol use disorders (AUD), addressing alcohol intolerance might be a crucial first step.

Factors Influencing Alcohol Intolerance

For many, a wine or a pint of beer is synonymous with relaxation and socialization. However, for others, these activities bring discomfort and illness. This raises a crucial question: Why can’t some people drink alcohol without feeling sick?

Alcohol intolerance is a condition that affects a surprising number of individuals worldwide. Here’s why this happens.


According to the National Institute on Aging, the way your body handles alcohol changes as you age. This means your bodies take longer to process alcohol, which leads to a higher blood alcohol concentration. This can make you feel the effects of alcohol more intensely than you did when you were younger.

Stress Levels

Like high-achieving people, high-stress environments can likewise change how you react to drinking. Stress has a variety of effects on your body, including cortisol production.

High amounts of stress can amplify alcohol’s effects. You may occasionally feel more drunk or hungover than normal as a result of this.

Health Changes

The way your body handles alcohol may affect chronic health conditions like liver disease. This is because alcohol and some medications may not interact well.

Many popular drugs have the potential to interact with alcohol, according to research. These combinations may result in fatal overdoses as well as other severe outcomes.


Certain genetics can affect the production of the enzymes. According to the Cleveland Clinic, people of East Asian descent are more likely to have gene variants that result in a buildup of acetaldehyde. This leads to a higher incidence of alcohol intolerance in this population.

Lifestyle Shifts

Lifestyle changes, whether it’s a new exercise regime, dietary habits, or sleep patterns, can influence our alcohol tolerance. Elements also such as social norms can affect drinking behaviors and the development of alcohol use disorder (AUD).

For instance, a healthier lifestyle might improve how your body handles alcohol. On the other hand, a lack of sleep or poor nutrition can exacerbate its effects.

Understanding these factors is important, especially if you find yourself in a high-stress, high-responsibility environment. Listening to your body and adjusting your habits are always good ideas.

Strategies for Managing Alcohol Intolerance

As a high achiever, you are used to managing a demanding work schedule in addition to your personal and social obligations. But what occurs when alcohol—a common staple at social events—begins to conflict with your body?

It might be uneasy to manage your alcohol sensitivity while leading an active, high-performance lifestyle. Here are some practical strategies to handle alcohol intolerance better.

Know Your Limits

Alcohol intolerance means your body doesn’t process alcohol as efficiently as it used to. Pay close attention to how much you can drink before negative symptoms kick in.

For some, this might be just one drink, while others might manage two. Recognizing your threshold and sticking to it is key. Knowing when to stop can prevent a night of fun from turning into a next-day regret.

Maintain a Healthy Lifestyle

To promote liver health, incorporate nutrient-dense foods like fruits and vegetables into your diet. Try eating a balanced diet to boost your immune system. Move your body to assist with natural detoxifying processes and encourage good circulation.

Additionally, avoiding spicy and acidic foods can reduce sensitivity to alcohol. Keeping a food diary helps evaluate specific triggers.

Furthermore, a medical practitioner could advise an elimination diet. They can identify which dietary sensitivity causes alcohol intolerance.

Stay Hydrated

This is one of the simplest yet most effective strategies. Alcohol is known as a diuretic, which means it causes your body to lose some water. It leads to dehydration and worsening hangover symptoms.

To counteract this, drink more water before, during, and after consuming alcohol. A good practice is to alternate between alcoholic and non-alcoholic drinks. This not only helps keep you hydrated but also slows down your alcohol consumption.

FAQs about Alcohol Sensitivity

Why do I always feel ill after drinking alcohol?

People often feel sick after drinking alcohol due to various reasons such as hangovers, insufficient sleep or food, or alcohol intolerance. Alcohol intolerance is caused by a lack of enzymes necessary to metabolize alcohol properly. This leads to symptoms like an alcohol flush reaction, skin problems, and digestive issues.

What medical conditions can lead to alcohol intolerance?

Conditions like asthma can influence alcohol intolerance, Hodgkin’s lymphoma, or liver damage. It can also be more common among individuals of Asian descent. Other factors include deficiencies in specific enzymes, intolerance to histamine, or sensitivity.

Can alcohol intolerance be treated?

The best way to prevent symptoms is to avoid alcohol or specific ingredients that trigger alcohol allergies. For minor alcohol intolerance symptoms, prescriptions may provide relief. By also joining an alcohol-free program, high-performing individuals can prevent sudden onset alcohol intolerance. They’ll be able to maintain a healthy and alcohol-free lifestyle.
