Are Allergies Hereditary? What Factors Influence Allergies?

Whether it’s winter or summer, the dread of allergies is always around the corner. This might lead to a question popping into your head: Are allergies more than just triggered symptoms? What if they’re a part of your genes? What do allergy specialists say? Here’s everything that you need to know.

Allergies & Genes

Allergies are the worsening of the immune system and its basic defense mechanism when something foreign invades the body and bloodstream. Allergies are primarily caused by agents that trigger the immune system. It can be anything, like:

  • Pollen
  • Hay
  • Dust
  • Mites
  • Insects
  • Pet fur
  • Certain foods and the list goes on

Even though the cause of allergies is pretty much determined, it’s still unknown why allergies happen in the first place. A lot of studies have supported the theory that allergies are a part of our genes and if there’s a long family history of allergies, then it’s highly probable that kids will have allergies as well, kind of like the case with asthma.

On the other end of the spectrum, allergies are thought to be the reaction of the body, when there are changes in the external environment, like bad weather, pollution, climate, etc. So, which one is it? Are allergies in the DNA of humans, or is it just an environmental thing?

It’s A 50-50 Chance

Allergies can be genetic. There is a possibility that allergies are aggravated by family history and that’s a fact. Several studies have been done on people and their families, some suffer from allergies, while others are normal. In the results, almost 80% of the people who had allergies passed them down to their kids and they also showed symptoms.

While that’s not completely the case because every circumstance can be different, there is still a lingering possibility that if your family has a history of allergies and weak immune systems, then the effects might pass down to the kids.

Genome studies have also suggested and supported the fact that allergies are, in fact, hereditary. Usually, when an allergen attacks the immune system, the body produces a compound called immunoglobulin E (IgE) and it has shown hereditary signs, upon testing.

It should be stressed that not all people who have an allergic history will fall victim to allergies. Sometimes, that just doesn’t happen. There are a lot of other factors that can cause allergies to rear their heads. This is why it’s a 50-50 case. Allergies can or cannot occur, even if you do have an allergy history in the family. It’s only a matter of time until you see where on the side of the line you stand.
