What’s A Food Allergy ?

A food allergy is when your body has an adverse reaction to a particular food. The immune system overreacts to the proteins in the food, thinking they’re harmful. This triggers the release of histamines and other chemicals that cause symptoms like swelling, hives, difficulty breathing, and even anaphylaxis (a potentially life-threatening condition).

 

Types of Food Allergies:

There are two types of food allergies: IgE-mediated and non-IgE-mediated.

  • IgE-mediated reactions happen immediately after eating the offending food.
  • Non-IgE-mediated reactions take longer to develop (usually hours or days) and are often more difficult to diagnose.

Symptoms of a Food Allergy:

The symptoms of a food allergy can range from mild to severe. They can include:

  • Itching or swelling in the mouth
  • Hives
  • Difficulty breathing
  • Nausea
  • Vomiting
  • Diarrhea
  • Anaphylaxis (a potentially life-threatening condition that requires immediate medical attention)

If you experience any of these symptoms after eating, it’s important to see a doctor as soon as possible. Only a medical professional can properly diagnose a food allergy.

 

Food Allergy Diagnosis:

A food allergy can be diagnosed with skin prick testing or blood testing.

 

Skin Prick Test:

During a skin prick test singapore, a small quantity of the suspected allergen is brought close to the skin and then puncturing the skin, allowing the allergen to insert the skin.

If you’re allergic to the substance, you’ll develop a raised bump or hive within 15 minutes.

Allergy Blood Test:

RAST blood test looks for antibodies that your body produces in response to an allergen. It’s generally considered to be less accurate than skin prick testing but is still useful in diagnosing allergies.

 

Allergy Treatment:

Once you’ve been diagnosed with a food allergy, it’s important to work with your doctor to create a treatment plan. Treatment plans will vary depending on the severity of your allergy and how long you’ve had it.

But in general, they will involve avoiding the allergen as much as possible and carrying epinephrine (a medication used to treat anaphylaxis) at all times in case of accidental exposure.

 

The Do’s and Don’ts of Dealing With Food Allergies

Whether you’re allergic to peanuts, shellfish, or something else entirely, dealing with food allergies can be a real pain. Not only do you have to be careful about what you eat, but you also have to be vigilant about cross-contamination and accidental exposure.

In short, it’s not always easy being a food allergy sufferer. However, there are some things you can do to make your life a little bit easier.

 

Allergy Test:

The Do: 

Get tested by a professional if you think you might have a food allergy. Many people self-diagnose their allergies, but this is not always accurate. If you suspect that you might have a food allergy, the best thing to do is to see a doctor or an allergist. They will be able to give you a definitive answer as to whether or not you actually have an allergy.

The Don’t: 

Assume that all members of your family have the same allergies that you do. Just because you’re allergic to peanuts doesn’t mean that your brother or sister is automatically allergic to peanuts as well. Everyone’s body is different, so it’s important to get everyone in your family tested individually.

 

Reaction and Medication:

The Do: 

Keep an epinephrine auto-injector with you at all times in case of an emergency. Epinephrine is the only medication that can counteract the effects of anaphylaxis, which is a potentially life-threatening reaction to an allergy trigger.

If you have an epinephrine auto-injector with you, make sure that it is within easy reach so that you can use it quickly if necessary.

The Don’t: 

Let your guard down just because you haven’t had a reaction in a while. Just because you haven’t had a reaction in a while doesn’t mean that you’re no longer allergic to the trigger. Always be prepared for the possibility of a reaction, even if it hasn’t happened in a while.

 

Final Thoughts on Allergies

If you suspect that you might have a food allergy, the best thing to do is to see a doctor or allergist for testing. To learn more about allergy, visit Ear and Allergy clinic in Singapore today.
