If you’ve ever had an allergy attack, you know how exhausting it can be. It doesn’t matter if it’s a seasonal allergy or a deadly allergy to certain foods. Allergy spells can drain you of all energy. And if you’re someone who doesn’t have any allergies, don’t b so quick to click away. Did you know you can develop allergies later in your life too?

Most people think that you can identify basic allergens early on in life, but that’s simply not true. Several studies have shown that you can, in fact, develop an allergy even in your 20s!

Can You Develop Allergies Later In Life?

Believe it or not, yes! You can definitely develop allergies that weren’t present before. Although this might come as a surprise to some, it’s not all that shocking. Since allergies are carried out in genetics, based on your family history, you could contract them if your parents are allergic.

Moreover, allergies that pop up into your adulthood could be a result of unexposed allergens. For instance, maybe you have always had a certain allergy but never came into contact with the allergen before. Or perhaps your immune system found something to be too harmful to you.

Not to mention, most allergies that develop later in your life revolve around shellfish, peanuts, and tree nuts.

When Are You Most Likely To Get An Allergy?

Typically allergies show themselves in children. However, that’s not always the case. Allergies can also surface in adults, no matter their age.

You might find yourself feeling irritated and bothered by things you were perfectly fine with a day before. For instance, you may have loved flowers and pollen before, but the next day you wake up with a runny nose, watery eyes, and an endless sneezing fit.

In addition to that, there’s no set time frame for when you develop an allergy. It could develop when you’re in your 20s, your 30s, or even when you’re 70 years old!

How Do Allergies Suddenly Develop?

Unfortunately, there’s no solid answer to that. Everyone has a different allergic reaction, and it develops differently in every individual.

Sometimes there are changes happening in your body to a specific allergen. It may be too slow to notice, but your body starts raising its defense system against the allergen before going into full attack mode.

At the same time, you might have always been allergic to something but probably never came into contact with it until you’re old enough. For example, maybe you’re born with an allergy to strawberries. However, if you’ve never had them in your childhood, you may never have discovered the allergy until eating them as an adult.


To sum it up, you can develop allergies later in life. It doesn’t matter if you’re a teenager or an adult; there are certain allergens that can affect your immune system no matter the time. This is why getting tested for allergies is essential, so you do not have to suffer from unpredictable reactions out of the blue.
