Avocado allergies aren't all that common, but for those who have this allergy, the symptoms can range from mild to severe, including the life-threatening condition anaphylaxis.
Because there's more than one type of avocado allergy and the symptoms can vary greatly in type and severity from person to person, it's important to have a doctor, allergist or immunologist diagnose this allergy.
Also, since other medical conditions or food allergies can cause similar symptoms, you will want to have those ruled out to determine if you are in fact allergic to avocados.
Many people who have an avocado allergy are also allergic to latex, as well as foods such as bananas, kiwis, tomatoes, papaya and chestnuts. Like the avocado allergy, being allergic to latex or any of these other foods is something you'll want to explore to avoid any serious health problems or reactions.
Oral Allergy Syndrome
The least severe type of avocado allergy is connected to Oral Allergy Syndrome (OAS).
In Oral Allergy Syndrome, the body reacts to foods that contain certain proteins in a similar way that it does with allergens like pollen.
Interestingly, there's a link between various pollen allergies and OAS. The Asthma and Allergy Foundation of America states: "up to a third of pollen allergy patients may be affected." (1)
Symptoms of an OAS response to avocados are usually limited to the lips, mouth and throat and can include:
Swelling of mouth, face, lips, tongue or throat
These symptoms usually appear rather quickly, but can sometimes happen an hour or more after consuming avocado or products containing avocado, such as guacamole.
A very small percentage of people with Oral Allergy Syndrome can get anaphylaxis, which click here is a very serious allergic reaction that requires immediate medical attention because it can be deadly.
The Latex-Avocado Allergy Connection
The American Academy of Allergy, Asthma & Immunology says that approximately 50% of people who are allergic to latex are also allergic to avocados. People with latex allergies may also have allergies to other foods such as bananas, chestnuts, kiwis and tomatoes. (2)
According to the Cleveland Clinic Foundation, some of the symptoms of a latex allergy can include a skin rash, hives, eye tearing, sneezing, congestion, wheezing and itching. (3)
Latex allergies can range from mild to life-threatening, so if you find out you're allergic to avocados, it's important to see a doctor to find out if you have a latex allergy too.
Even if you're not allergic to latex, you can still have symptoms related to the latex version of the avocado allergy.
