Are Allergies Inherited? | Understanding the Role of Genetics in Allergies

One of the most common questions I get from parents is:
“Doctor, are allergies inherited?”

The answer is yes — allergic conditions often run in families. If one parent has allergies, their child has a 30–50%chance of developing allergies. If both parents are allergic, the risk rises to 60–80%.

But here’s the key point:
🧬 Children don’t always inherit the exact same allergy. Instead, they inherit a tendency — a sensitive immune system that may overreact to everyday substances like:

• Dust mites

• Pollen

• Pet dander

• Certain foods

• Moulds

This is why we often see what’s called the "Allergic March" — where allergic symptoms evolve over time:

• Infants may show eczema (atopic dermatitis)

• Young children might develop food allergies or asthma

• Older kids and teens can begin showing signs of allergic rhinitis (sneezing, nose block, etc.)

What Can You Do?

If allergies run in your family, it's a good idea to:

• Be alert to early symptoms like frequent colds, itchy rashes, or breathing issues

• Avoid known triggers in the home environment

• Get an early allergy evaluation with a certified allergist
