How to spot an allergy or intolerance

What’s the difference between an allergy and an intolerance?

If you suspect that milk or a certain food is making your baby feel unwell or react suddenly, it can be quite unsettling to begin with. But there’s a helpful way to tell the difference between a food allergy and a food intolerance and that’s how quickly the reaction takes place.

Allergy

With an allergy, the signs are usually there within minutes or seconds. An allergy is when the immune system gets a bit confused by reacting to an allergen in the food and builds up antibodies to attack it. The body releases defence chemicals, which cause an allergic reaction such as sneezing, swelling or a rash. It’s important you get your doctor to diagnose an allergy if you suspect one.

Intolerance

With an intolerance, the symptoms might be similar but the reaction usually takes longer and doesn’t involve the immune system. Upset tummies are often the main complaint.
