What Causes Alcohol Intolerance

Experiencing symptoms of illness or nauseousness, having sinus congestion, diarrhea, skin flushing, and/or vomiting is a familiar thing to those who have had one too many drinks on a certain occasion. So what does it mean if these symptoms come into effect after only one drink, even a couple of sips of alcohol? This inability to enjoy even one glass of wine or beer without experiencing discomfort occurs as a result of a condition known as alcohol intolerance, closely related but not to be confused with alcohol allergy and Asian/alcohol flush reaction. So what exactly is alcohol intolerance and through which symptoms can we recognize it?

Alcohol Intolerance Definition and Symptoms

Being intolerant to alcohol means experiencing sudden unpleasant reactions, oftentimes very similar to allergic reactions, after ingesting even the smallest amount of alcohol. It’s common knowledge that alcohol tolerance increases by regularly consuming alcoholic beverages, but not in this case since this kind of intolerance can happen out of the blue and surprise you by sticking for a long time. The following are the most common symptoms of alcohol intolerance:

  • Nasal congestion
  • Skin redness and flushing
  • Nausea
  • Vomiting
  • Diarhhea
  • Headaches
  • Heartburn and/or gas
  • Increased heart rate
  • Worsening of asthmatic reactions

As you can see, the symptoms are similar to those of a hangover, with the key difference of not being experienced the day after, but rather immediately after a few sips of alcohol.

In order not to confuse alcohol intolerance to alcohol allergy and Asian flush reaction, let’s go over the causes and compare them to those of the two latter conditions.

Alcohol Intolerance Causes

This condition can be caused either by a genetic trait or a damaged liver, the former being the primary reason. This being said, the following are the most common causes for alcohol intolerance:

Enzyme Deficiency

This is the main reason why oftentimes this condition is confused for Asian flush reaction, since enzyme deficiency is the principal cause for both. So, if you’re not sure which one you have, talk to your doctor so you know which one applies to you.

Enzyme deficiency means that your digestive system has a dysfunctional enzyme, therefore cannot properly metabolize the alcohol you ingest. While Asian flush reaction is the result of two dysfunctional enzymes, alcohol intolerance is usually caused by improper function of just one.

Many people, especially those of Asian descent, are born with an inefficient enzyme called acetaldehyde dehydrogenase (ALDH). This enzyme, which is produced by the liver, is responsible for digesting the ingested alcohol, or to be more exact, converting the harmful toxin acetaldehyde into a less toxic compound called acetic acid. Accumulation of acetaldehyde in the liver can be very detrimental, as it is a cancerogenic toxin, so the inefficiency of the ALDH enzyme causes just that. This acetaldehyde build up results in the above-mentioned symptoms, especially skin flushing and increased heart rate, so read further if you wish to know how to prevent this from happening.

Histamine Intolerance

Histamines are chemicals which are naturally produced by our bodies, but are also present in certain foods and fermented alcoholic beverages like beer, champagne, and especially wine. When the ingested histamine is not properly broken down it accumulates, just as the previously-mentioned acetaldehyde, in this manner causing the aforesaid symptoms with an accent on nasal congestion and skin flushing.

This histamine build up develops due to improper metabolization of the ingested histamine by one or two of the following enzymes: diamine oxidase (DAO) and histamine-N-methyltransferase (HNMT). So, by not processing the histamine correctly, which is usually the main job of the DAO enzyme, one can experience symptoms similar to those of an allergic reaction, which is why these two conditions are often not so distinguishable.

Sulfites Intolerance

Sulfites have been very useful to us from Roman times onward, since these compounds are used as additives for preserving foods and beverages while preventing bacterial growth. However, sulfates can be found naturally in many alcoholic drinks like wines (especially white), beer, vermouth, sake, and some others.

If you have a sensitivity or intolerance to sulfites, the reaction may be increased when consuming sulfites-rich alcohol. The symptoms are similar to those caused by histamine intolerance, meaning that they can easily be confused with allergy-like reactions, so by doing an intolerance test you can confirm or deny this cause for your alcohol intolerance.

How to Prevent Alcohol Intolerance

If the cause for your alcohol intolerance is histamine or sulfites intolerance, then unfortunately the only way to prevent the symptoms is by avoiding alcohol.

However, if caused by enzyme deficiency, there are two ways in which you can treat the discomforting symptoms: antihistamine use and Sunset pills. The latter is more effective than the former, and here’s why.

Antihistamines (Histamine Blockers)

Antihistamines are commonly used for treating some of the Asian flush reaction symptoms, since this condition is also caused by the deficient ALDH enzyme.

The problem with antihistamines is the fact that they do not solve the problem, which is accumulation of the toxic compound acetaldehyde, but merely mask mild symptoms like facial redness for example. By doing this, the acetaldehyde remains in your system and your blood alcohol level increases which means that you may become drunk only after two beers. What’s more, by continual use you build up tolerance so each time you drink you’ll have to increase the amount of antihistamines you use.

All of these things make antihistamine use dangerous, so beware if this is the treatment of your choice when it comes to alcohol intolerance.

Sunset Pills

Sunset pills are the best product for preventing alcohol intolerance-induced symptoms caused by enzyme deficiency, so let’s explain why this is.

As we just mentioned, antihistamines only mask some of the symptoms while staying passive when it comes to acetaldehyde accumulation. Well, Sunset pills not only prevent the appearance of the symptoms, but help this enzyme out by acting as its direct assistant. Hence, in this manner, by preventing the build up of this dangerous toxin, our pills take care of the root problem instead of just masking it.

This happens as a result of the following incredible ingredients present and the balance in which the Sunset pills are formulated.

  • N-acetyl cysteine (NAC) – an amino acid which breaks down into the extremely potent antioxidant Glutathione; reduces inflammation; directly assists the ALDH enzyme to break down acetaldehyde.
  • L-Theanine – non-protein amino acid; prevents alcohol-induced free radicals; works together with the NAC amino-acid.
  • Quercetin – antihistamine; reduces inflammation; helps the body produce more of the powerful antioxidant Glutathione.
  • Bromelain – natural enzyme; helps the body to absorb Quercetin better; assists the deficient enzymes to better metabolize the alcohol.
  • Piperine – alkaloid; increases the potency of the product.
  • Thiamine – vitamin B1; helps out the NAC amino acid; controls the accumulation of acetaldehyde.
  • Vitamin C – helps out the NAC amino acid to easily break down into the antioxidant Glutathione; controls acetaldehyde accumulation.
  • B Vitamins – assistants to the above-mentioned ingredients.

These extremely effective ingredients make Sunset pills the most potent product for treating alcohol flush reaction and alcohol intolerance caused by enzyme deficiency.

Do you have this problem and this sounds too good to be true? Feel free to try our Sunset pills and we guarantee positive results and a worry-free night out with your friends or you’ll get your money back.

Other causes

Beware that alcohol intolerance can also occur due to antibiotics or antifungal medication use as these meds can sometimes prevent the ALDH enzyme from working properly, so talk to your doctor if you think this or liver damage is the cause.
