Cow's milk protein allergy and intolerance in infancy Some clinical, epidemiological and immunological aspects
Latex Allergies
A latex allergy is when your body's immune system overreacts to certain kinds of proteins found in natural rubber latex that's used to make things like rubber gloves, condoms, and some medical devices.
Doctors don't know what causes it. Coming in contact with latex and rubber products over and over may be part of the reason it happens.
About 5% to 10% of health care workers have some form of latex allergy.
Other people who are more likely than most people to get it include those who have:
Rubber industry workers and people who use condoms are also more likely than others to get a latex allergy.
You can get exposed to latex:
There are three types of latex reactions:
1. Irritant contact dermatitis. This is the least-threatening type, and it's not an allergic skin reaction. It usually happens due to repeated exposure to chemicals in latex gloves and leads to dryness, itching, burning, scaling, and skin problems. This generally starts 12-24 hours after contact.
2. Allergic contact dermatitis. This is a delayed reaction to additives used in latex processing. It results in the same type of reactions as irritant contact dermatitis. But the reaction is more severe, spreads to more parts of the body, and lasts longer. Symptoms can start anywhere from 1 to 4 days after you've come in contact with latex.
3. Immediate allergic reaction (latex hypersensitivity). This one is the most serious. It can show up as a nasal allergy with hay fever-like symptoms, conjunctivitis (pinkeye), cramps, hives, and severe itching. It's rare, but symptoms may also include rapid heartbeat, tremors, chest pain, trouble breathing, low blood pressure, or anaphylaxis, a severe allergic reaction that can be life-threatening.
If you have severe symptoms, call your doctor or 911 immediately, or go to the nearest emergency room.
Doctors diagnose a latex allergy in people who:
If you need a skin test to check on a latex allergy, an allergy specialist must supervise it, in case you have a severe reaction.
There's no cure for a latex allergy. If you're allergic to latex, the best course of action is to avoid contact with it. If you do have a reaction, the treatment will depend on how serious it is. For irritated skin, these may be enough:
If your reaction is severe, you may need these right away:
If you have a latex allergy, wear a medical alert bracelet or another type of ID in case of an emergency. You may also need to carry two epinephrine shots if your doctor recommends that.
An allergy to latex can become worse the more you come in contact with it. If you know you have this condition, be aware of products that may have the potential to cause a reaction. Ask your doctor if you need to avoid them.
Many items have latex in them. Read product labels carefully. You may need to ask product makers to be sure.
Home goods that are made with latex include:
Outside the home, latex is also in many items, such as:
Medical products containing latex include:
Tell them about your latex allergy at least 24 hours before your appointment. The hospital or doctor's office should have a plan in place so they can use products like nonlatex gloves to treat you.
Ask for the first appointment in the morning. Even if your doctor or dentist uses latex-free gloves for you, there can be latex particles in the air from gloves used with other patients. You're more likely to avoid these particles by getting there early.
If you have to stay in the hospital, you'll usually be given your own room, free of products that might give you a reaction.
Between 30% and 50% of people who have a latex allergy also have reactions to eating, touching, or even smelling certain foods. This happens because some fruits and vegetables have proteins that are structured a lot like the ones that cause the reaction to latex. It's called a cross-reaction.
These foods include:
Almonds, peppermint, and mustard can also cause cross-reactions.
If you're allergic to any of these foods, you may also have a latex allergy, even if you don't know it. Let your doctor and dentist know so they can keep from exposing you.
Dental Health And Latex Allergy
Latex, also known as rubber or natural latex, is derived from the milky sap of the rubber tree, Hevea brasiliensis. Latex can be found in many household products and also in many medical and dental supplies including gloves, masks, and syringes.
Latex allergy develops in some individuals after repeated exposure to products containing natural rubber latex. As is the case in any allergy, a latex allergy arises when an individual's immune system overreacts to an otherwise harmless substance (called an allergen).
In this case, the immune system overreacts when a latex-containing dental device or supply -- such as gloves -- comes into contact with the mucous membranes (the eyes, nose, or mouth) of a susceptible individual. Even the powder used on latex gloves can contain the latex proteins and become airborne when the gloves are removed, causing upper airway allergic reactions or asthma symptoms in susceptible people.
The exact cause of latex allergy is unknown, but repeated exposure to latex and rubber products is thought to trigger symptoms.
Other than health care workers, people at increased risk for developing latex allergy include those who have:
There are three types of allergic reactions to latex:
If you experience severe symptoms of a latex allergic reaction, call your dentist, doctor, or 911 immediately, or go to the nearest emergency room.
A skin or blood test can diagnose a latex allergy. Skin testing for latex allergy should only be done with the close supervision of an allergy specialist because of the risk of severe reactions.
In addition, a person may be diagnosed with a latex allergy if they have experienced signs or symptoms of an allergic reaction (skin rash, hives, eye tearing or irritation, wheezing, itching, difficulty breathing) when exposed to latex or natural rubber products.
Allergic reactions to latex may be treated by removal of the latex product and drug treatment according to the type of symptoms developing. If the symptoms are irritant contact dermatitis, antihistamine and/or corticosteroid drugs may be enough to treat symptoms. Severe reactions should be treated with epinephrine, intravenous fluids, and other support by hospital or emergency personnel.
If you have a latex allergy, it is important for you to wear a medical alert bracelet and carry an emergency epinephrine syringe. Epinephrine is the treatment used for severe allergic reactions.
There is no cure for latex allergy, so the best treatment for this condition is prevention. Besides the foods already mentioned in this document, there are other foods that might trigger a latex-like allergic reaction in people with latex allergy. If you suffer from latex allergy, avoid these foods:
Note: Not all people who have these food allergies will also have latex allergies.
If you have a known latex allergy, call your dentist's office at least 24 hours before your scheduled appointment. Your dentist and their staff should have a latex-free protocol that they follow for patients with latex allergies. They will also make a note of your allergy in your medical record.
You could develop a latex sensitivity to the gloves. This is different from a latex allergy. With latex sensitivity, you'd develop a swelling or a rash in the area where the gloves touched you. This would be an irritant contact dermatitis. A true allergic reaction is more serious, is less common, and would cause symptoms including shortness of breath, wheezing, full-body rash, and swelling.
From Papaya To Tomato: 7 Foods You Should Avoid If You Have Latex Allergy
When we think of latex, our mind automatically jumps to a rubber-like material. So it may sound bizarre that someone with latex allergy also needs to stay away from certain foods, which can trigger cross-reactions due to the similarity between the proteins in latex and those in specific fruits and vegetables.
According to the American College of Allergy, Asthma, and Immunology, latex allergy causes hives, itching, stuffy or runny nose, wheezing, chest tightness and difficulty breathing. Shockingly, it can also be fatal and hence people who deal with latex allergy need to stay away from the following foods:
PapayaPapaya contains enzymes with similarities to latex proteins, making it a common trigger for cross-reactions. According to a study titled Latex-Papaya Syndrome, all the participants with latex allergy had a history of papaya-induced anaphylaxis. Individuals with latex allergies may experience oral symptoms such as itching or swelling after consuming papaya.
Bananas
Bananas are known for cross-reactivity with latex, as they share similar proteins. While not everyone with a latex allergy will react to bananas, it's essential to be vigilant, especially if you've experienced cross-reactions in the past.
AvocadoAvocado is another fruit that can elicit cross-reactions in individuals with latex allergies, according to a study by the American Allergy of Allergy. The proteins in avocados may trigger allergic responses, ranging from mild oral symptoms to more severe reactions in sensitive individuals.
KiwiKiwi is a fruit that contains proteins similar to those in latex. Consuming kiwi may lead to cross-reactions in individuals with latex allergies, causing symptoms such as itching, swelling, or even more severe allergic responses.

Mango
Mango contains proteins that can cross-react with latex allergens. Individuals with latex allergies may experience oral symptoms or more severe reactions after consuming mango, especially if they have heightened sensitivity.
ChestnutsChestnuts, particularly European chestnuts, can trigger cross-reactions in those with latex allergies. Roasted or raw chestnuts may contain proteins that elicit allergic responses similar to those experienced with latex exposure.
TomatoWhile less common, some individuals with latex allergies may experience cross-reactions with tomatoes. The proteins in tomatoes can share similarities with latex, leading to allergic responses in sensitive individuals.
