Can a latex allergy cause cross-reactions?

Repeated exposure to a protein in natural rubber latex can make someone more likely to develop latex allergy.

Some cross-reactive foods include avocado, banana, kiwi, chestnut, peach, potato, tomato and bell pepper. MedlinePlus also lists kiwi, peaches, nectarines, celery, melons, tomatoes and papayas.

These foods are possibilities, not a prediction that every person with latex allergy will react to them. You do not need to avoid fruits and vegetables unless you have had an allergic reaction to them.

Cambridge University Hospitals describes food allergy in about half of people with type 1 latex allergy. A study reports latex-fruit syndrome in 36.4% of its patients with natural rubber latex allergy.

Food cross-reaction symptoms may start within 5 to 30 minutes after eating a cross-reacting food.

Symptoms can include itching or irritation in the mouth, swelling of the lips or tongue, and sometimes small bumps or blisters.

A fruit allergy may prompt recognition of previously undiagnosed latex allergy, or fruit allergy may develop after years of latex exposure and sensitivity. Latex allergy often develops after many previous latex exposures.

You do not need to avoid every food on a cross-reaction list if you eat it without problems.

Cambridge University Hospitals says you do not need to avoid fruits and vegetables unless you have had an allergic reaction to them. Leeds Teaching Hospitals advises continuing foods you or your child currently eat without problems, including foods on cross-reaction lists.

Call emergency services right away for a severe allergic reaction. Severe-reaction signs can include difficulty breathing or swallowing, dizziness or fainting, confusion, vomiting, diarrhea or stomach cramps.

Before surgery or another procedure, tell healthcare professionals about a latex allergy.

Natural rubber latex comes from liquid sap from tropical rubber trees. Latex allergy is associated with proteins in natural rubber latex.

Can a food allergy happen before latex allergy is recognized?

Yes. A fruit allergy can lead someone to recognize previously undiagnosed latex allergy.

Is latex allergy the same as a rubber tree sap allergy?

Latex allergy is a reaction to proteins in natural rubber latex, which comes from Hevea brasiliensis tree sap. Some synthetic rubber materials called latex lack those natural rubber proteins.

Does a latex allergy mean I should stop eating every food on cross-reaction lists?

No. You do not need to avoid fruits or vegetables unless you have had an allergic reaction to them.
