Keep reading to learn more about how to notice the signs of garlic allergy in you or your loved ones today, helping you take proactive actions to keep safe and tend to your symptoms.

How Does An Allergic Reaction to Garlic Work?

Garlic allergies are caused when your body’s immune system mistakenly interprets garlic as harmful, creating antibodies that trigger the release of histamine and other defensive chemicals to ‘protect’ you from the threat.

It is these chemicals that then launch a full-blown allergic reaction, activating your body’s inflammatory response and unpleasant symptoms. These reactions can occur immediately when you come into contact with garlic or within two hours.

Compared with other food allergies, garlic allergies are rare.

Garlic allergy vs. Food Intolerance: What’s The Difference?

It is possible to experience an adverse reaction to garlic without being allergic. This is called food intolerance, and it tends to be caused when your body lacks the enzyme needed to digest a specific food type.

Garlic intolerance symptoms tend to be milder than an allergy and are centered around the digestive tract, such as stomach pain or heartburn.

Intolerance to garlic can, unfortunately, be a significant problem for people with irritable bowel syndrome (IBS) and requires medical attention.

What Are The Main Symptoms of Garlic Allergy?

Garlic Allergy symptoms tend to range from mild to severe. These may include:

  • Hives
  • Contact dermatitis
  • Skin inflammation 
  • Tingling sensation across the lips, mouth, or tongue
  • Nasal congestion, including a runny nose or sneezing
  • Vomitingstomach cramps, and diarrhea
  • Wheezing and shortness of breath
  • A sudden drop in blood pressure, accompanied by an anaphylaxis reaction

Anaphylaxis: Warning Signs

Anaphylaxis can be a life-threatening condition requiring immediate medical attention. If you or your loved one experience any of the following symptoms, we’d urge you to seek emergency help right away:

  • racing pulse
  • Sudden drops in blood pressure
  • Swelling around the throat, including struggles to breathe
  • Dizziness or lightheadedness
  • Fainting 

Other Foods To Avoid

Garlic is part of the allium family, which is a food group that also contains many popular vegetables such as:

  • Onions and shallots 
  • Leeks 
  • Chives 

If you are allergic to garlic, therefore, it is likely that your immune system may react to these foods, too, in a process called cross-reactivity.

It is also worth noting that thanks to its punchy flavor, garlic or garlic extract is often added to many packaged or processed foods such as boxed rice, sauces, stews, and bread. So, read food labels carefully to avoid triggering an allergic reaction.

Seeking Medical Help

To receive a garlic allergy diagnosis, the first step often involves visiting an allergist who will likely complete a blood test and a skin prick test to measure your body’s reaction to controlled amounts of garlic exposure.

As with many food allergies, keeping a detailed food diary can be a great way to help you and your allergist identify exactly which ingredients might be triggering your adverse reactions.

Especially if you’re experiencing a severe allergic reaction, your doctor may recommend an elimination diet where you cut out garlic entirely. As with all food allergies, however, we invite you to seek professional support before attempting to alter or restrict your diet.

How To Treat A Garlic Allergy Rash

One of the most common symptoms of a garlic allergy is skin inflammationhives, and an itchy rash such as contact dermatitis.
