Alcohol Intolerance

Alcohol intolerance is a disease in which the body can’t properly break alcohol because of insufficient key enzymes such as Aldehyde Dehydrogenase (ALDH) and Alcohol Dehydrogenase (ADH). This condition can cause an accumulation of a toxic by-product named acetaldehyde that causes annoying symptoms like headaches, rapid heart rate, facial flushing, vomiting, and nausea.

Alcohol Intolerance Symptoms & Causes are primarily linked to genetic mutations, particularly affecting the ALDH enzyme, which is especially common in people of East Asian descent. This condition may also arise from medical issues like histamine intolerance or celiac disease, as well as from taking certain medications. Alcohol intolerance can often be managed by avoiding alcohol, as continued consumption may worsen symptoms. Individuals experiencing persistent or severe symptoms should consult a doctor for proper management, though the condition is not life-threatening; it mainly impacts social interactions and lifestyle choices.

Symptoms

Alcohol intolerance is produced, as the body can’t properly break down the alcohol, causing several unpleasant symptoms. Some of the symptoms are discussed below.

• Facial Flushing: Redness on the face and neck from acetaldehyde buildup, causing blood vessels to swell.
• Headaches: Acetaldehyde triggers blood vessel expansion in the brain, causing migraine-like pain.
• Nausea and Vomiting: Alcohol irritates the stomach, leading to nausea and vomiting as the body attempts to expel it.
• Rapid Heart Rate: Difficulty processing alcohol may increase heart rate as the body responds to toxin buildup.
• Stuffy or Runny Nose: Alcohol dilates blood vessels, causing nasal congestion or excess mucus.
• Dizziness: Acetaldehyde and reduced alcohol breakdown can lead to dizziness and imbalance.
• Low Blood Pressure: Alcohol widens blood vessels, lowering blood pressure and causing lightheadedness.

When to See a Doctor 

If you are observing symptoms such as extreme fainting or dizziness and difficulty in breathing, you must consult a doctor. After the consumption of even a small quantity of alcohol, the presence of persistent symptoms such as facial flushing, nausea, and headaches may indicate the need for medical attention.

Don’t ignore such symptoms because untreated diseases rapidly grow. These symptoms may also indicate other medical conditions such as celiac disease, genetic enzyme deficiency, or histamine intolerance. Consulting a doctor will help in diagnosing and treating alcohol intolerance appropriately. Fitwell Hub provides the services of experienced doctors to manage alcohol intolerance and other related complications. You can see our provided services and book an appointment with the doctors to consult about your symptoms.

Causes

Alcohol intolerance is usually caused when the body can’t properly break alcohol because of insufficient key enzymes. This disease is frequently inherited, but some other factors may also cause Alcohol intolerance. Some common causes are:

• Genetic Mutation: Common in East Asians, a genetic mutation affecting the aldehyde dehydrogenase enzyme causes acetaldehyde buildup, leading to facial flushing, nausea, and headaches after alcohol consumption.
• Histamine Intolerance: Some people process histamine slowly, causing runny nose, headaches, and flushing after drinking histamine-rich alcohols like beer and wine.
• Sulfite Sensitivity: Sulfites in beer and wine can cause shortness of breath, hives, or wheezing, especially in people with respiratory issues like asthma.
• Celiac Disease: Gluten in some alcoholic beverages can cause digestive problems in people with celiac disease, worsening alcohol intolerance.
• Medication Interactions: Certain medications, like antihistamines and antibiotics, can increase alcohol intolerance symptoms, causing dizziness, headaches, or nausea.
• Chronic Liver Disease: Liver disease impairs alcohol processing, leading to acetaldehyde buildup and symptoms like fatigue, nausea, and vomiting.

Risk Factors

Certain risk factors may increase the chances of alcohol intolerance development. The main risk factors are linked to genetics, lifestyle, and basic health conditions. Some of the risk factors are discussed here:

1. Genetics: The main risk factor for the development of alcohol intolerance is genotype, especially when an individual inherits a mutation in the ALDH2 gene. This mutation may affect the ability of the body to break down alcohol, especially in East Asian descent. When one or both parents possess these gene mutations, there are great chances of the development of alcohol intolerance in their children.
2. Age: The ability to process alcohol may decrease with an increase in age, as the enzyme production decreases naturally and variations occur in the functioning of the liver. Older adults can also experience alcohol intolerance symptoms although they didn’t find any problems in their earlier life.
3. Pre-existing Health Conditions: Health conditions such as asthma, histamine intolerance, or celiac disease can cause an individual to have alcohol intolerance. These diseases can make your body respond negatively to definite compounds like gluten or sulfites found in alcohol, worsening the symptoms.
4. Medication Use: Medications such as antifungals, antidepressants, or antibiotics may increase the unpleasant effects of alcohol and lead to toxic reactions because of enzyme inhibition. If you are using such medicines, consult a doctor before the consumption of alcohol, as these medications can interrupt the body’s ability to metabolize alcohol.
5. Chronic Liver Disease: People with severe liver diseases like hepatitis or cirrhosis are more prone to alcohol intolerance. The functionality of the liver is disturbed and becomes less efficient in metabolizing alcohol, causing symptoms like vomiting, fatigue, or nausea after consumption of alcohol.

Complications

If left untreated, alcohol intolerance can lead to severe complications. These can affect both Physical & Mental Well-Being. Alcohol intolerance may result in several complications if not properly managed. 

• Injury: One of the major complications is an increased risk of getting injured, especially for people who have dizziness or fainting experiences. This may cause falls or accidents during routine tasks due to impaired motor coordination and slow reactions. 
• Chronic Headaches: Chronic headaches are also a possibility in instances where frequent drinking takes place even with an intolerance. This could significantly impact an individual’s life, starting a cycle of tiredness and irritability.
• Digestive Disorder: In addition, nausea, vomiting, or stomach pain that worsens over time are some gastrointestinal issues and eventually cause long-term digestive disorders. 
• High Blood Pressure: Furthermore, high blood pressure can be experienced by individuals with alcohol intolerance due to their heart rate racing fast or flushing. 
• Breathing Problems: Moreover, breathing problems, hives, or anaphylaxis might result from allergic reactions toward substances including histamine or sulfites present in alcoholic drinks. 
• Mental Health Problems: The effect of alcohol intolerance on mental health can not be ignored because the negative reactions caused by alcohol may trigger anxiety, social isolation, and depression.

Prevention

To prevent symptoms and complications of alcohol intolerance, one should take the following precautions:

1. Limit or avoid drinking alcohol.
2. Go for low-histamine drinks free of sulfites.
3. If you are on medication, consult a doctor before taking any alcohol.
4. Do not consume alcoholic beverages if you have asthma or celiac disease
5. Look out for early signs of intolerance
6. Drink a lot of water and eat before you drink alcohol

Diagnosis

To diagnose alcohol allergy, a doctor will look for signs and symptoms and do tests to confirm the diagnosis. The doctor will go through your medical history and look at symptoms you have after consuming alcoholic drinks followed by tests to know what is behind it. Accurate diagnosis must be made for successful management and treatment. Some Tests discussed given below:

• Genetic Testing: This test detects changes in the ALDH2 gene that are frequently found in people with alcohol allergies. This examination can prove whether an allergic predisposition exists or not.
• Blood Tests: Blood tests assess acetaldehyde levels along with liver functioning. High rates of acetaldehyde levels in the blood plus abnormal liver enzyme results may show impaired alcohol metabolism.
• Histamine Level Testing: Testing histamine levels may establish if a person has histamine intolerance related to the consumption of alcohol. High levels of histamine increase the intensity of symptoms related to alcohol intolerance.
• Liver Function Tests: These tests judge whether the liver is healthy enough and it breaks down alcohol properly. Liver function tests that indicate underlying liver conditions that could contribute towards alcohol intolerance.
• Allergy Testing: Allergy testing helps identify allergic reactions to certain substances found in most alcoholic beverages like sulfites that may worsen its symptoms.

FitwellHub offers comprehensive diagnostic services including these tests through their advanced laboratory facilities. To learn more about FitwellHub assistance along with effective diagnosis and managed health solutions, visit the FitwellHub Lab.

Treatment

In managing alcohol intolerance, consider these treatments:

• Avoidance of Alcohol: The most effective way to avoid the effects of alcohol intolerance is to abstain from alcohol completely. This treatment approach will remove the risks of having negative reactions and related complications.
• Lifestyle Adjustments: Making lifestyle changes such as avoiding certain foods and drinks that cause intolerance symptoms worse, can help manage this condition. In addition, having a balanced diet and drinking enough water is beneficial.
• Medication for Symptoms: In case of severity, doctors may prescribe medicine to handle issues like headaches or nausea. By so doing, they relieve suffering and enhance life quality.

Medications

To treat alcohol intolerance, medications can be used to manage symptoms or address underlying issues:

• Antihistamines: These may help relieve problems like headaches and flushing caused by histamine intolerance. Their main work is inhibiting the actions of histamine receptors thus reducing allergic reactions.
• Anti-Nausea Medications: Nausea and vomiting caused by alcohol intolerance can be controlled through the use of medicines such as meclizine or ondansetron. The work of such medications is to target the brain parts that cause nausea.
• Pain Relievers: Common over-the-counter pain relievers like acetaminophen or ibuprofen are useful in managing associated headaches and body discomfort. These medicines should be taken under medical care to abstain from liver strain.
