Things You Need to Know About Food Allergies

Food allergies are a big deal. Every year, people die from reactions to the food they’re allergic to. But what exactly is a food allergy? What are the symptoms? How do you know if you have one? And most importantly, what can you do about it?

In this blog post, we’ll answer all of these questions and more. So whether you’re concerned about food allergies or just want to learn more about them, keep reading!


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

Dealing with food allergies can be difficult, but it’s important to be vigilant about avoiding potential triggers and being prepared for emergencies. 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.

Allergies Management

Spring is in the air and for many people, that means allergies are, too. If you’re one of the millions of Americans who suffer from allergies, you know how miserable they can make you feel.

Do you have allergies? You’re not alone. In fact, allergies are quite common. According to the Asthma and Allergy Foundation of America, more than 50 million Americans suffer from allergies each year.

There are many different types of allergies, and the symptoms can vary depending on the person and the severity of the allergy. Some people might have a mild reaction, while others may have a more severe reaction that could even be life-threatening.

It’s important to know what type of allergy you have so that you can get the proper treatment. The good news is that there are a variety of treatments available to help you get your allergies under control and enjoy the warmer weather.

Types of Allergies

There are many different types of allergies, some of them are as follows:

Food Allergies

If you have a food allergy, your body has a reaction to a protein that is found in a particular food. The most common food allergens include milk, eggs, peanuts, tree nuts, soy, wheat, fish, and shellfish.

People with food allergies must be very careful to avoid their allergens as even a small amount can trigger a severe reaction.

Symptoms of a food allergy reaction include hives, difficulty breathing, swelling of the face or throat, nausea, vomiting, and diarrhea. In severe cases, anaphylaxis can occur which can be life-threatening.

Seasonal Allergies

Seasonal allergies are also known as hay fever or allergic rhinitis. They occur when your body has a reaction to pollen from trees, grasses, or weeds. Seasonal allergies are more common in the spring and fall but can occur year-round in some parts of the country.

Symptoms include sneezing, runny nose, congestion, itchy eyes, and fatigue.

Pet Allergies

Pet allergies are caused by proteins found in an animal’s skin cells or saliva. These proteins become airborne and can cause an allergic reaction when inhaled.

Pet allergies are relatively common; in fact, 15% of people with allergies are allergic to cats and dogs. Symptoms include sneezing; runny nose; watery eyes; coughing; wheezing; and itchy skin (hives).

Contact Allergies

A contact allergy occurs when your skin comes into direct contact with an allergen such as latex or certain metals (nickel is a common one). Poison ivy is another type of contact allergy that occurs when your skin touches the oil found in poison ivy plants.

Symptoms of a contact allergy include redness, itchiness, swelling, and blisters. Treatment typically involves avoiding the allergen and using topical corticosteroids or oral antihistamines to relieve symptoms.

Allergy Treatments

There is no cure for allergies but there are treatments available that can help you manage your symptoms so you can enjoy your life without being miserable.

Allergy Shots:

Allergy shots, also known as immunotherapy, are a treatment that can help reduce or eliminate your symptoms of allergies. The shots contain a small amount of the allergen that is causing your reaction and are given over a period of time. This treatment helps to “desensitize” your body to the allergen and can help lessen or prevent future reactions.

Immunotherapy is a type of allergy treatment that helps your body build up immunity to your allergens over time so that you will have fewer and less severe reactions. It is usually given as shots but can also be given as sublingual tablets or drops that are placed under the tongue.

Immunotherapy is not appropriate for everyone so it’s important to talk to your doctor about whether it might be right for you.



Antihistamines are a medication that is used to treat allergic reactions. They work by blocking the action of histamine, which is what causes many of the symptoms of an allergy. These can be taken orally or applied topically (such as in eyedrops).

Nasal Sprays:

Nasal sprays are a medication that is used to treat nasal allergies. They work by shrinking the swollen tissues in your nose and helping to clear out mucus and other allergens. Nasal sprays can be used daily to help control your allergies.


Decongestants are a medication that is used to treat nasal congestion caused by allergies. They work by shrinking the swollen blood vessels in your nose and helping to clear out mucus and other allergens.

Decongestants should only be used for a short period of time as they can cause side effects such as high blood pressure, heart palpitations, and headaches.


For more severe symptoms or for people who cannot take oral medications due to other health conditions such as asthma or heart disease, there are injectable medications available that can provide relief.

Eye Drops:

Eye drops are a medication that is used to treat itchy, watery eyes caused by allergies. They work by reducing inflammation in the eyes and help to relieve symptoms quickly. Available over-the-counter or by prescription, eye drops should be used regularly to keep your eyes comfortable and symptom-free


If you’re one of the millions of people who suffer from allergies, you’re not alone—allergies are actually quite common. And while they may seem like nothing more than a nuisance at times, it’s important to be aware of the different types of allergies and how to treat them should you come into contact with an allergen.
