Food allergies are very common and often unexpectedly manifest themselves later in life. Symptoms vary dramatically and because they can often be misleading, it is best to consult a medical health practitioner rather than Dr. Google.
What should you do if you suspect you might have a food allergy? | Health24
Some food allergies are easy to diagnose – like when someone eats peanuts and immediately experiences a rash and swelling. Other food allergies are a bit harder to recognise, and may start later in life.
A physical check-up by a medical professional is an important first step. Your doctor must know your symptoms to be able to help you rule out any other causes. If underlying medical causes are ruled out, your doctor will use blood tests or a skin prick test to measure your immune response to certain foods.
If you know that your symptoms are not caused by any other digestive issues, your doctor might suggest that you try the elimination diet – where you eliminate the suspect food(s) from your diet and gradually reintroduce them.
Although elimination helps to link your symptoms to certain foods, it’s not the perfect way to diagnose a food allergy. You might just have a food intolerance, not an actual allergy.
You should also know the difference between food intolerance and a food allergy. An intolerance can cause unpleasant symptoms such as nausea, stomach ache or other digestive issues, while a food allergy can be life-threatening in the case of anaphylaxis.
