What Are the Signs of an Allergic Reaction to Avocado?

By Meshell Powell
Updated: Feb 06, 2024

An allergic reaction to avocado can take on two different forms. The first is known as a birch pollen allergy, and the second involves an allergy to latex products. Some of the most commonly reported symptoms include skin reactions, swelling, and digestive disturbances. In the most severe cases, a potentially fatal type of allergic reaction known as anaphylaxis may develop.

A birch pollen allergy is the most common form of allergic reaction to avocado. This type of allergy typically causes local reactions and does not spread throughout the body. Common symptoms include redness, irritation, or swelling around the mouth or other parts of the body that have come into contact with a product containing avocado. These symptoms typically develop within a few minutes of contact and usually go away soon thereafter without any particular medical treatment, depending upon the severity of the allergy.

The second type of allergic reaction is related to a latex allergy and is much more severe. Severe skin reactions such as hives or eczema may occur among those with this type of allergy. Abdominal cramping and other gastrointestinal disturbances may also develop. Foods such as kiwi, bananas, and melons are related to the avocado and should be avoided by those with this type of allergy.

Anaphylaxis is the most severe type of allergic reaction to avocado and can prove to be fatal within a matter of minutes if emergency medical assistance is not obtained. Symptoms of anaphylaxis may include chest pain, facial swelling, and difficulty breathing. Those who suffer from this type of reaction may require oxygen therapy or other life-support measures in a hospital setting. A special type of injectible medication known as epinephrine is usually prescribed for those who have had an anaphylactic reaction and is designed to be carried by the patient at all times in the event of a recurrence. Since may people may not be able to immediately discern the difference between a mild and severe allergic reaction, it is best for individuals to talk to a medical professional if any potential allergic symptoms develop.

I get a really bad bloaty gastrointestinal reaction, burp a lot, and have a bad taste in my mouth for a couple days every time I eat avocado. It sucks because I love the taste either sliced in salads or mashed in guacamole. I have also noticed swelling and a slight topical irritation of the tongue, but no difficulty breathing, eczema, or itching. Afraid to eat it knowing I'm going to pay for days after. Is there a pill similar to bean-o or lactaid to counteract/prevent the symptoms? Will continued consumption cause any long-term harm?

I totally understand people being allergic to processed foods but it's strange how some people are allergic to natural foods.

I had avocado and was so sick to my stomach. But I can eat kiwi or bananas with no problem. Any suggestions?

I used to get stomach cramps and diarrhea whenever I ate avocados. I stopped eating them for about a year and then tried eating them again. Surprisingly, I can eat them without problems now.

I don't know if I had an allergy to them or just a sensitivity, but I guess taking a break from them was enough. I'm so happy I can eat them again because they're so nutritious and tasty.

@dljohn-- I don't get lip swelling, I get an itchy rash when I eat avocados.

Do you have the same reaction to kiwi or bananas? Do you get stomach cramps? If so, it's probably a latex allergy and you need to avoid avocados.

If you don't have other symptoms, it might be a pollen allergy. You should get an allergy test to see how allergic you are. It might be okay to have avocado in small amounts occasionally in that case but you have to check with your doctor.

Does anyone experience slight itching and swelling of the lower lip after eating avocado?
