Can you suddenly become allergic to something?
Allergies can develop at any point in a person’s life. Usually, allergies first appear early in life and become a lifelong issue. However, allergies can start unexpectedly as an adult. A family history of allergies puts you at a higher risk of developing allergies some time in your life.
What causes food allergies to develop?
What causes food allergies? Food allergies happen when the immune system – the body’s defence against infection – mistakenly treats proteins found in food as a threat. As a result, a number of chemicals are released. It’s these chemicals that cause the symptoms of an allergic reaction.
Can a food sensitivity turn into an allergy?
Food allergy and food intolerance are commonly confused, as symptoms of food intolerance occasionally resemble those of food allergy. However, food intolerance does not involve the immune system and does not cause severe allergic reactions (known as anaphylaxis).
What causes allergies to develop?
Allergies develop when your immune system mistakenly identifies a substance such as pollen, mold, animal dander, or food as harmful. That substance is referred to as an allergen. The allergen stimulates immune system cells to release certain chemicals, such as histamine, which then lead to allergy symptoms.

How long do food allergies last?

What happens if you keep eating food you’re intolerant to?
What happens if you eat something you’re “intolerant” to? You might get some of the same symptoms as a food allergy, but it can’t trigger anaphylaxis. Over time, however, this reaction can damage the lining of your small intestine and can keep you from absorbing the nutrients you need from your food.
What is the difference between a food sensitivity and an allergy?
The difference between a food allergy and sensitivity is the body’s response. When you have a food allergy, your immune system causes the reaction. If you have a food sensitivity or intolerance, the reaction is triggered by the digestive system.

Can Allergies Be Cured?
No, but you can treat and control your symptoms. You’ll need to do all you can to prevent being exposed to things you’re allergic to — for example, staying inside on days when the pollen count is high, or enclosing your mattress with a dust-mite-proof cover. Allergy medicine can also help.
