Food allergy incidence around the Globe
Studies show that the prevalence of food allergy is increasing in both Western countries and developing countries in Asia and Africa during the last decade.
“Most people think that the allergic symptoms are not severe, just skin rashes or other conditions that are inconvenient rather than fatal,” said Prof Emeritus Pakit Vichyanond, director of the Samitivej Allergy Institute (SAI) at Samitivej Thonburi Hospital as interviewed by The Nation Newspaper (on 16 November 2018). “In fact, if the allergy affects more than two body systems or leads to anaphylaxis, death might occur.”
What is a food allergy and what are the symptoms?
Excessive adverse effects to a certain kind of food is a sign that your immune system is displaying an allergy to proteins in the food. The reaction can be immediate or appear as much as two hours after eating, even if you have only had a small amount of that food.
Symptoms can be mild to moderate-tingling in the mouth, skin rash, nasal congestion, vomiting, abdominal cramps, diarrhoea, dizziness, swelling of the tongue and throat – or they can be very serious like anaphylaxis.
Anaphylaxis is the life-threatening complication. It is unpredictable and occurs suddenly making it potentially life threatening. One of the most dangerous symptoms of anaphylaxis is swelling of the throat, making it difficult or impossible to breathe, possibly resulting in acute cardio-respiratory distress. Other anaphylaxis symptoms include abdominal pain, vomiting, diarrhoea, oedema of lips and tongue, diffuse skin rash, low blood pressure, elevated and abnormal heart beats, chest pain and faintness. If you know that you suffer from anaphylaxis, you should carry your Epi-Pen with you at all times.
However, most people confuse food allergies with food intolerance. There’s a difference between these two things. The latter does not involve the immune system, but rather a problem in the digestion process.

How to keep yourself safe from food allergies
When eating out at restaurants you can reduce your risks by checking menus about ingredients, or asking someone to help you understand the ingredients of each dish you want to eat.
Therefore, if you have doubts about the ingredients of your favorite dish, be sure to ask about both the ingredients and the way it is cooked to ensure food allergens are not included in the dish for your own safety.
Is an allergy test necessary for you?
In fact, there is no standard test to confirm or rule out a food allergy. Family background, type, and frequency of reactions, skin and blood tests usually form the diagnosis. Your doctor might ask you to skip a suspected food for a couple of weeks to see if the symptoms stop.
However, when it comes to an allergy test, there are several primary methods of testing for allergies as follows:
- Skin test for allergy
- Immunotherapy
- Drug desensitisation
- Blood test for allergies
If you suspect you are allergic to something it is worth getting yourself checked; but make sure if your insurance covers the allergy test or if it is claimable. Usually, health insurance will pay upon particular food allergy status based on the ICD-10-CM Diagnosis Code.
If you have allergy symptoms, you can easily buy over-the-counter drugs which will typically help to reduce mild symptoms. If these drugs do not help your symptoms, then it is time to see your doctor.
