There is no sure way to prevent food allergies, but there are some things you can do to reduce the risk:
Introduce new foods slowly and one at a time.
Be aware of the foods that commonly cause allergies, such as peanuts, tree nuts, eggs, milk, soy, wheat, and fish.
If you have a family history of food allergies, talk to your doctor about whether your children should be tested.
Why are allergies dangerous
Allergies can be dangerous because they can cause anaphylaxis, which is a potentially life-threatening reaction.
Anaphylaxis occurs when the body has a severe allergic reaction to a substance, such as food, medication, or insect venom. Symptoms of anaphylaxis include difficulty breathing, swelling of the throat and tongue, and a drop in blood pressure. If not treated immediately, anaphylaxis can lead to death.
People with allergies should always carry an epinephrine auto-injector (such as an EpiPen) with them in case they have a severe reaction.
How to introduce new foods to avoid allergies
When introducing new foods to someone who may be allergic, it is important to do so slowly and carefully. Allergies can develop over time, so it is important to watch for any adverse reactions after each exposure. If there are any signs of an allergic reaction (such as itching, swelling, or difficulty breathing), stop the exposure and seek medical attention immediately.
When should children be tested for allergies
There is no one definitive answer to this question. Some parents choose to have their children tested for allergies as early as possible, while others wait until their children show signs or symptoms of an allergy before having them tested.
Some experts recommend that children be tested for allergies if they have a family history of allergies, if they have had repeated episodes of wheezing or other respiratory problems, or if they have eczema.
If you are considering having your child tested for allergies, talk to your child's doctor to discuss the risks and benefits of testing.
How to test for allergies
There are a few ways to test for allergies. One way is the skin prick test, where a small amount of allergen is pricked into the skin. If you are allergic to the allergen, you will develop a small bump or hive at the site. Another way to test for allergies is the blood test, where a sample of your blood is taken and tested for antibodies to specific allergens.
Medication for allergies
There are many different types of medication available for allergies, and the best type for you will depend on your specific allergy. Some common medications include antihistamines, decongestants, and corticosteroids.
If you have a severe allergy, you may need to carry an EpiPen with you at all times in case of an emergency.
What are antihistamines
Antihistamines are drugs that are used to treat allergies. They work by blocking the action of histamine, a substance that is produced by the body in response to an allergy. Some common antihistamines include cetirizine (Zyrtec), fexofenadine (Allegra), and loratadine (Claritin).
What are decongestants
Decongestants are medications that are used to relieve congestion and pressure in the sinuses and ears. Examples of decongestants include pseudoephedrine, phenylephrine, and oxymetazoline. Decongestants work by narrowing the blood vessels in the nose and sinuses, which reduces swelling and inflammation.
Common side effects of decongestants include headache, dizziness, and nervousness.
What are corticosteroids
Corticosteroids are a class of steroid hormones that are produced in the adrenal cortex of vertebrates, as well as the synthetic analogues of these hormones. Corticosteroids are involved in a wide range of physiological processes, including stress response, immune response, and regulation of inflammation, metabolism, and electrolyte balance.
There are two main types of corticosteroids: glucocorticoids and mineralocorticoids. Glucocorticoids are involved in stress response, immune response, and inflammation. Mineralocorticoids are involved in electrolyte balance and regulation of blood pressure.
Where can you find help to treat food allergies
If you have a food allergy, you can find help from your local allergist or immunologist. You can also find help from the Food Allergy and Anaphylaxis Network (FAAN).
FAAN is a national nonprofit organization that provides education, advocacy, and support for people with food allergies.
