Garlic is an indispensable ingredient in our kitchens to add flavor and aroma to our food. However, some people do not like this garlic at all. Even eating a little garlic, or even touching it, can cause various allergic reactions. It can cause difficulty breathing and rashes. Today we are going to talk about this garlic allergy, or `(Garlic Allergy)`. It is also important to remember that this condition can occur in people of any age.
What is Garlic Allergy?
Simply put, a garlic allergy is an unwanted reaction by your immune system to garlic. Our body's immune system is supposed to protect us from disease. But sometimes, this system mistakes something harmless, like garlic, for a dangerous enemy . That's when these allergy symptoms occur.
The important thing is that there are two things called a garlic allergy and a garlic intolerance. Don't confuse the two.
- Garlic Allergy: This happens when your immune system reacts to garlic. Antibodies are formed in the body and various chemicals are released. The symptoms can sometimes be very severe . It can affect any system, including the skin, respiratory system, circulatory system, and digestive system.
- Garlic Intolerance: This is usually related to your digestive system . The immune system is not involved at all. Symptoms like bloating, stomach cramps, nausea, and diarrhea are common. This is similar to someone with ``IBS (irritable bowel syndrome)``, or a condition where some people cannot digest milk (lactose intolerance). This can also happen when the body lacks the enzymes needed to digest certain foods.
So, you probably understand the difference between the two. In an allergy, the symptoms are usually more intense and appear quickly.
How common is garlic allergy?
To be honest, garlic allergy is not that common . Most people have a condition where they can't stand garlic. However, if you're feeling any discomfort, it's best to see a doctor to find out for sure if it's an allergy or something else.
What are the symptoms of a garlic allergy?
These symptoms can vary from person to person. Also, these symptoms can appear within a few minutes to two hours after eating or touching garlic. In the case of garlic poisoning, the symptoms may take several hours to appear, and the symptoms are not as severe.
Here are some of the most common symptoms:
- Hives, itching, and skin discoloration. Sometimes these can occur all over the body, not just at the site of contact with garlic. Some people may also develop a condition called contact dermatitis .
- Swelling of the mouth, tongue, or throat. This is a slightly alarming sign.
- Difficulty breathing, wheezing.
- Stomach ache, nausea, vomiting, diarrhea.
- Rapid heartbeat, dizziness, fainting.
- Anaphylaxis: This is the most dangerous and life-threatening allergic reaction . It can cause sudden shortness of breath, drop in blood pressure, and loss of consciousness.
Important: If you experience severe allergic symptoms after eating or touching garlic, especially difficulty breathing or swelling of the throat, call 911 immediately and get an ambulance or go to the nearest hospital. This is an emergency!
Sometimes, the reaction can also vary depending on how you use garlic. For example, you may not have any reaction to cooked garlic in sauces or gravies. However, if you eat a piece of raw garlic, you may have a severe allergic reaction. However, if you experience any discomfort or pain from garlic, do not take it lightly . It is very important to tell a doctor.
Why does this garlic allergy occur?
As mentioned earlier, food allergies occur when our immune system mistakes certain foods as "enemies." The same thing happens with garlic. To deal with this "threat," the body releases chemicals like histamine and creates inflammatory cells. This reaction is what results in allergic symptoms.
In fact, doctors still don't have a clear understanding of why only some people develop these types of allergies and others don't.
If you're allergic to garlic, are you also allergic to onions?
This is a question that many people ask. You may be allergic to garlic but not be allergic to onions. However, many people are allergic to both . The reason for this is that both onions and garlic are bulbs that belong to the same plant family (Allium family). The proteins in them are very similar. Therefore, your body may react to both in the same way.
We call this cross-reactivity . Other plants that are close relatives of garlic include leeks, chives, and shallots (a small onion like a red onion). You won't be allergic to every plant in the same family. However, research has shown that this cross-reactivity can be a problem for people with garlic allergies.
What are the risk factors for garlic allergy?
Some factors may increase your risk of developing a garlic allergy:
- If anyone in the family has allergies (Family history of allergies).
- If you have conditions like asthma or eczema .
- If you are allergic to similar plants such as onions, chives, or leeks, someone who reacts to one of these is more likely to react to garlic as well.
Possible complications of garlic allergy
Most of the time, garlic allergies are not severe enough to be life-threatening. However, sometimes severe symptoms or a life-threatening condition called anaphylaxis can occur. Research shows that eating or touching raw garlic is more likely to cause anaphylaxis than cooked garlic.
How to diagnose garlic allergy?
Food allergies are generally a bit difficult to diagnose because we eat a lot of different foods and ingredients at the same time.
To diagnose this, a doctor or allergist will ask you about your symptoms and review your medical history. In addition, some tests may be done to determine if garlic is causing your symptoms:
- Skin Prick Test: This involves placing a very small amount of an allergen on your skin, making a small puncture, and then checking to see if there is any reaction (such as redness or swelling).
- Blood Tests: Some blood tests can check whether your immune system is reacting (producing antibodies) to a specific food (e.g. garlic).
- Food Challenge Test: This is done only under the supervision of a doctor, in a hospital setting . In this, the doctor gives you a small amount of garlic and carefully observes you to see if you have any allergic reactions.
Warning: Never try to "eat garlic and see what happens" at home on your own. It's safest to do these types of tests in a place with medical facilities to deal with a severe reaction.
How serious is a garlic allergy?
Most garlic allergies are not serious. However, it is important to talk to a doctor about your symptoms and avoid garlic until you know exactly how sensitive you are.
How do you treat garlic allergy?
The best and only treatment is to avoid garlic completely .
If you suddenly experience minor symptoms (such as itching, hives) after eating or touching garlic, you can get relief from antihistamines that you can buy at a pharmacy or supermarket. For example, there are medications like `(diphenhydramine - Benadryl®)` or `(cetirizine - Zyrtec®)`. However, it is wise to seek medical advice before taking these.
For more severe reactions, use in an emergency. Your doctor may prescribe an emergency epinephrine auto-injector (Epinephrine auto-injector - EpiPen®) . Keep this with you and use it in case of a severe allergic reaction. Remember, even if you use an EpiPen®, you should still call emergency medical services immediately , because the medicine can wear off after a while.
Another important thing to note is that garlic is a common ingredient in many pre-packaged and processed foods . Sometimes, the ingredient list may not explicitly state "garlic." So, if in doubt, it's best to avoid the food or call the manufacturer.
Garlic is used in many dishes in our country and abroad. Before ordering food from a restaurant, inform the staff that you have a garlic allergy. Then they will be able to recommend a dish without garlic for you.
Here are some other things you can do:
- Thoroughly wash any utensils, cutting boards, knives, and cooking surfaces that have come into contact with garlic.
- Tell a restaurant employee about your allergies before you order. The chef may be able to prepare your meal separately or provide you with a list of safe foods.
- If you're going to a party or picnic, tell the host that you're allergic to garlic. They may be able to tell you what ingredients were used, or give you an alternative dish. Or, you can bring your own food.
- Use other spices like paprika, oregano, cumin, and basil to flavor your food.
Can garlic and onion allergies be cured?
Most food allergies cannot be cured . The best thing you can do is to avoid the foods you are allergic to and prevent allergic reactions. And be prepared to deal with any sudden reactions that may occur.
Sometimes children can outgrow their garlic allergy as they get older. But only a doctor can confirm that. Sometimes they do tests for it. It's rare for adults to outgrow a food allergy.
What if I have a garlic allergy?
Living with a garlic allergy means always being aware of what's in your food . This can be a bit difficult, but it's something you need to do to avoid a dangerous allergic reaction.
It's important to be mindful of this when eating out at restaurants, at friends' houses, and when shopping. This can help you reduce the chance of accidentally eating or touching garlic. The good news is that even people with garlic allergies can find plenty of garlic-free recipes.
Is garlic allergy permanent?
Most food allergies don't go away easily. However, sometimes, especially in young children, the allergy can go away. Never go to the doctor to test your allergies on your own . Do this only under the supervision of a doctor.
Can garlic allergy be prevented?
No, you can't prevent a garlic allergy. You can only manage your allergic reaction by avoiding garlic or taking medication.

- Salad dressings
- Frozen meals

Since herbs like chives, onions, and shallots are similar to garlic, some people may find it beneficial to avoid those foods as well.
When should I see a doctor?
