The 2023 study indicated that people with ME/CFS were more likely to experience alcohol intolerance, and that those with this symptom experienced more symptoms overall. Other factors like coexisting morbidity, drinking, body mass index, exercise, and the SARS-CoV-2 strain responsible for the infection, did not show significant correlation with allergy risk. Some people report that they are able to start drinking small quantities of alcohol again as time goes on – especially if their health is improving.

• The 2004 study supported the anecdotal belief that people with the condition reduced or ceased alcohol intake.
• Alcohol intolerance – often complete but sometimes partial – is a very characteristic symptom of ME/CFS that can happen quite suddenly right at the start of the illness.
• Within these groups, approximately 150,000 participants from South Korea, 77,000 from the UK, and 542,000 from Japan had been infected with SARS-CoV-2.
• “Previous to the infection or previous to the disease, the intolerance was not present,” Dr. Vaughn said.

New study reveals increased risk of allergic diseases after COVID-19 infection

After getting ME/CFS, I have developed a clear intolerance of alcohol. I was never a big drinker, but around the time of being diagnosed with ME/CFS I found that the smallest amount of alcohol impacted my ability to use my legs and since then I have really abstained from it. Although I have never been a big drinker, I was able to tolerate alcohol with a likely hangover. We’ve received many comments over the years from people with ME/CFS describing their experiences with alcohol. Alcohol reactions and sensitivity are not well characterized in the literature as it relates to post-viral illness. Azthena may occasionally provide inaccurate responses.

Severity of infection and allergy risk

This increased risk was consistent for infections from both the original and Delta variants of the virus. After adjusting for all known variables that could affect the outcome, the researchers discovered that individuals infected with SARS-CoV-2 showed a 20% higher occurrence of allergic diseases compared to those not infected. This large-scale analysis aimed to shed light on the ethnic variations in post-COVID-19 allergic reactions. Symptoms of PASC, in some cases, include immunologic phenomena that may cause allergic conditions of various kinds. Additionally, nearly half of COVID-19 cases have to deal with delayed or chronic morbidity, which may have set in during or after the acute phase of infection. Now, some people battling back from COVID, are saying they get sick from just a few sips of alcohol.

There is no certain answer as to whether drinking alcohol again is going to cause any harm or delay any natural recovery process if you feel able to drink again. We don’t know why alcohol intolerance occurs – partly because very little research has been carried out. Two-thirds of those in the study reduced alcohol intake because it increased symptoms, and one-third ceased because ‘it seemed sensible’. The 2004 study supported the anecdotal belief that people with the condition reduced or ceased alcohol intake. Post-acute sequelae of SARS-CoV-2 (PASC), or long COVID, is characterized by persistent symptoms after acute SARS-CoV-2 infection that can vary from patient to patient.

• Now, I am unable to drink any more than 2 glasses of wine without vomiting a few times.
• During their medical consultation, the patients self-reported new changes in their symptoms or behaviors following the use of alcohol.
• This large-scale analysis aimed to shed light on the ethnic variations in post-COVID-19 allergic reactions.
• According to the ME Association out of the UK, tens of thousands of people have had some sort of post COVID illness lasting more than one month.
• This potential revelation, could help in diagnosing and potentially treating patients going forward.

As ME/CFS does not normally affect liver function, where alcohol is metabolised/broken down, it is unlikely that the problem lies there. Alcohol intolerance – often complete but sometimes partial – is a very characteristic symptom of ME/CFS that can happen quite suddenly right at the start of the illness. Alcohol intolerance can cause an immediate or delayed (20-30 mins) uncomfortable reaction.

The two-dose cohort had comparable allergy risk as the controls, both overall and for the various allergy subgroups. Those who had received the vaccine had a 44% higher risk of allergy (with one dose). Moderate-to-severe COVID-19 was linked to a 50% higher risk of overall allergy, compared to 14% among those with mild disease. The chance of getting allergic rhinitis was 25% higher in the infected group, though no significant increase was observed for food allergies or atopic dermatitis.

ME Association Website Survey: Alcohol Intolerance: ME/CFS and Long Covid

While there have been some anecdotal reports of new alcohol sensitivity in PASC patients in the media, there is a paucity of published data in the medical literature about this topic. Moreover, while the risk for allergic diseases decreased over time after the infection, it didn’t disappear entirely. The study aimed to investigate how ethnicity affects allergic conditions following COVID-19. These are called post-COVID-19 conditions or post-acute sequelae of COVID-19 (PASC), otherwise known as long COVID. A recent study published in Nature Communications explored the association of COVID-19 with long-term allergic conditions.

“Previous to the infection or previous to the disease, the intolerance was not present,” Dr. Vaughn said. According to the ME Association out of the UK, tens of thousands of people have had some sort of post COVID illness lasting more than one month. If you’ve had a drink that hit you harder than you thought it should after a COVID infection, it could be telling you something. I haven’t noticed any adverse effect from the very small amount of alcohol I drink.

How a sip of booze could help diagnose a COVID long hauler syndrome

I am not even able to drink a small bucks-fizz. From my experience, I have found that my ability to tolerate alcohol has decreased quite considerably. Now, I am unable to drink any more than 2 glasses of wine without vomiting a few times. I have noticed, without question, that I am unable to handle and tolerate alcohol to the level that I was able to before ME/CFS. I used to be able to drink several Cointreau and orange, but on my parents 40th Wedding Anniversary in 2007 – 3 years after falling ill – half a one sent my head spinning.

In Alabama, Dr. Jordan Vaughn says he’s seeing patients regularly with lingering issues from COVID. A report indicates a splash of alcohol could help detect long hauler problems. Have you noticed an intolerance since developing ME/CFS or Long Covid? I became intolerant to alcohol after ME/CFS started. I just avoid alcohol completely.

Dr. Liji Thomas

She has counseled hundreds of patients facing issues from pregnancy-related problems and infertility, and has been in charge of over 2,000 deliveries, striving always to achieve a normal delivery rather than operative. Multiple pathways have been proposed to account for the observed correlations, including T cell disruption, regulatory T cell (Treg) disturbances, and the cytokine storm in acute severe COVID-19. The findings broadly corroborate earlier research, but there is a need for more studies on the allergic sequelae of COVID-19 on a larger and more multinational scale.

About the study

It also indicates that COVID-19 vaccination with at least two doses weakens the risk of new allergies. It emphasizes the relationship between COVID-19, especially moderate to severe, and subsequent allergy onset. This decrease in risk varied from country to country. Specifically, the likelihood of developing asthma in those infected was more than double, at 2.25 times that in non-infected individuals.

In ME/CFS and Long Covid we know that alcohol intolerance can be an issue for some people, that it is regarded as an additional diagnostic symptom in ME/CFS, and that alcohol consumption can cause an exacerbation of other symptoms. “This is the first study that provides comprehensive evidence for the association between SARS-CoV-2 infection and subsequent incident allergic outcomes.” Other people refrain from drinking alcohol because they are too unwell and feel it is sensible or have chosen to abstain from alcohol completely. A new onset of alcohol sensitivities should be assessed along with other post-COVID-19 symptoms and may provide novel avenues to explore the pathobiology of illness and potential interventions. During their medical consultation, the patients self-reported new changes in their symptoms or behaviors following the use of alcohol.

Within these groups, approximately 150,000 participants from South Korea, 77,000 from the UK, and 542,000 from Japan had been infected long covid alcohol intolerance with SARS-CoV-2. Pecifically, the South Korean segment included more than 800,000 people with an average age of 48. It caused over seven million deaths and many times that number of infections and hospitalizations. This potential revelation, could help in diagnosing and potentially treating patients going forward. What Doctor Vaughn says you can do, is document and combine multiple symptoms to come to a diagnosis. “One of the definitions of post viral fatigue syndrome is there’s not a laboratory abnormality,” Dr. Vaughn said.
