One, a 49-year-old woman, used to consume several drinks per week before getting COVID. Now, her tolerance has decreased so dramatically that she has not had any alcohol for seven months. On one occasion, one glass of wine caused such a bad reaction that she felt she could not move. Alcohol sensitivity is also emerging as a possible symptom of long COVID, but very little medical research has looked into the phenomenon. The new study is limited, analyzing the cases of four Stanford patients who had long COVID symptoms lasting longer than a month, but offers a serious look at the possible link.

There’s growing evidence that it may be a unique symptom of long COVID, particularly the post-viral fatigue syndrome (PVFS) type. In lieu of specific treatments, people with long Covid must balance their rest and activity in a strategy called pacing, Brode said, and receive physical and cognitive behavioral therapy for further support. More often than not, many people end up relying on several drugs, including the antiviral Paxlovid, to treat symptoms.

However, these cases reported here may reflect a larger population of individuals with PASC who suffer from new-onset alcohol sensitivity following COVID-19. Objective measures, such as blood alcohol levels, in future research on larger cohorts would also provide additional quantitative insight into the degree of alcohol reaction relative to ingested amount. For humans, sniffing represents active sampling to likely improve olfactory function 36. In particular, we sniff much stronger and vigorously to detect a weak odor, so a common assumption is that stronger airflow during inhalation (sniffing) may benefit olfactory sensitivity. But we often overlook the fact that due to the protective location of the human olfactory epithelium, only a small portion of inhaled air can reach there. So, potentially, modulating the distributions of the intranasal airflow can be more effective than increasing the overall airflow; however, until now, we have no effective way to test that.
What is a low histamine diet?
Otherwise, Malcolm suggests drinking plenty of water to stay hydrated and possibly pursuing some blood work to better understand what may be causing your symptoms. A low histamine diet could help too, which excludes most fermented products like wine, beer, and cured cheese. Some other foods to consider avoiding include fish, tomatoes, spinach, citrus fruits, eggs, and chocolate. Long COVID, also known as post-COVID conditions, occurs when health problems last for weeks, months or even years after a coronavirus infection. It was recognized by the American With Disabilities Act in 2021 and roughly 30% of adults may experience at least one COVID symptom that lasts three months or more, according to research.
- While hand sanitizers containing 60-95% ethyl alcohol can help destroy the coronavirus on surfaces, drinking alcohol offers no protection from the virus.
- According to Grayson, some supplements may also alleviate symptoms relating to long COVID – especially tiredness.
- She explains that long COVID can affect you even if your initial infection caused only mild symptoms – or none at all.
- This may be an effective approach for patients with nasal obstruction and insufficient airflow to the olfaction region to begin with, but could extend to patients with sensorineural causes of smell losses, such as post-COVID-19.
- Linear mixed model (SAS Enterprise v9.4) was used to examine the changes of detection thresholds or odor identification scores between baseline and different manipulations (pinch, nasal plug) with random intercepts for each participant.
Individuals with a lowered tolerance, also known as acute sensitivity, may experience the effects of intoxication even after consuming relatively small amounts of alcohol. This study demonstrated the potential to enhance olfactory functions in healthy and patient cohorts through improving intranasal air and odorant delivery using two creative yet simple novel smell-aids. The results further broaden our knowledge of the importance of intranasal airflow distribution on olfactory function in both healthy and diseased states, as well as the discovery of novel methods to modulate its distribution. Only with a better understanding of the impact of nasal anatomy and its modulation on transport odorants with varying physiochemical properties can we better improve olfactory function through peripheral mechanisms.
Current recommendations for the management of alcohol sensitivity include abstinence, avoidance, or the use of antihistamines to see if the severity of the reaction may be reduced 33. Patients may be advised to avoid the type of drink or ingredient that may be triggering symptoms. The connection between differences in alcohol type and physiological effect is unclear, including whether it is the ethanol content itself or other compounds that are contained within various types of drinks, such as histamines and sulfites.
Alcohol can impact our health and increase the risk of developing COVID and long COVID. Recent research also shows that long COVID may be linked to the development of alcohol intolerance and exacerbated hangovers. Alcohol has acute and long-term effects on our health, which can directly intersect with COVID-19. While causes of long COVID remain inconclusive, Harvard researchers have found that lifestyle influences could affect the risk of developing long COVID. One of these influences is (drumroll, please) alcohol, but that street can go both ways.
Although inconvenient, not being able to drink alcohol isn’t the most earth-shattering of symptoms compared with more serious effects. Although the underlying mechanisms aren’t fully understood, the symptom may be linked to the broader condition of long COVID and share similarities with conditions like myalgic encephalomyelitis/chronic fatigue syndrome (ME/CFS). Long Covid is known to cause over 200 different symptoms in nearly a dozen organ systems, including those of the heart, lungs, kidneys, brain, eyes and skin, but there’s no approved test for it or recommended treatment. Research shows long Covid is more common in middle-aged people, particularly women and those with weakened immune systems, but anyone who catches the virus can get it.
Clues in the eyes, gut and immune system
One reason is that the impact of the complex nasal cavity anatomy on nasal airflow is relatively unclear, and the degree of variation in olfactory acuity that the conductive factors can account for has not been entirely determined 24,25,26. A 60-year-old male with no covid and alcohol intolerance prior medical history presented with five months of persistent symptoms following acute COVID infection, including headache, cognitive impairment, anxiety, and mood and sleep disturbances. These symptoms were disruptive to his regular activities including work and recreation. The patient reported a mild to moderate acute COVID infection that was managed outpatient with supportive care. Prior to his initial COVID infection, the patient reported consuming alcohol twice a month with no issue or reactions. The patient experienced chronic, daily headaches characterized by a squeezing sensation at the top and back of the head, typically worst at night.

- Our 1st invention is a novel “nasal plug” made from foam ear plugs (classic soft™, 311–6000, 3M, Saint Paul, MN) with a plastic straw, 5 mm in diameter (purchased from local supermarket), manually embedded in a diagonal direction (~ 30°).
- Here you’ll find information on what is known about long COVID and alcohol tolerance.
- Our understanding of why individuals develop OI after viral illnesses is incomplete, but it is plausible that this could be a key mechanism by which alcohol consumption aggravates symptoms in those recovering from viral infections.
This may be because alcohol use can weaken your immune system, making you more prone to infectious diseases. «The patient experienced chronic, daily headaches characterized by a squeezing sensation at the top and back of the head, typically worst at night,» according to the study. During the COVID-19 pandemic, there have been some reports of lingering effects of COVID-19 on alcohol tolerance and drinking habits.
Long COVID – also called post-COVID syndrome – refers to ongoing or new symptoms that appear after recovering from the primary phase of a COVID-19 infection. New studies confirming the link between long COVID and alcohol intolerance may suggest that quitting or cutting back on alcohol is the best course of action. Stanford researchers clarified in their writings that they did not find a “definitive causal link” between long COVID and alcohol sensitivity, due to the limited size of their study. The COVID-19 pandemic is affecting every family across the country and will likely have a long-lasting impact on public health and well-being. Alcohol misuse is already a public health concern in the United States, and alcohol has the potential to further complicate the COVID-19 pandemic in multiple ways. Below are links to important resources for the public, clinicians, and researchers from NIAAA.
At the same time, people with active alcohol use disorder shouldn’t suddenly stop drinking without medical supervision, as alcohol withdrawal can be dangerous. Changes in drinking behavior, either drinking more or less than usual, can affect your alcohol tolerance, as well as the impact of alcohol on your life. Rates of relapse among those in recovery from alcohol use disorder have also reportedly increased – due to similar risk factors, as well as challenges accessing treatment.
It’s also worth noting that the effects of alcohol — and a hangover — may be particularly unpleasant if you also have COVID-19 symptoms. If you’re ready to enter treatment and stop drinking, you’ll likely have to wait until your COVID-19 infection is no longer transmissible before you enter a detox program. «Women should have no more than 1 drink per day and men no more than 2 drinks per day,» the medical school said.
All the extra histamine may explain why some people feel terrible after drinking alcohol post-COVID. Rachakonda said it’s not unreasonable to request a blood test if you’re experiencing alcohol intolerance. Checking your liver enzymes, as well as your kidney function and electrolytes, can help rule out any other causes.
