Food Allergy: How does that happen?

If you don’t know how a person gets allergic, here it is- when some foreign substance gets in your body that your immune system is not used to, you may get an allergy. These foreign substances may be pollen, dust particles, bee venom, pet dander, etc. In special cases, food is also considered as an active trigger of allergy. It may happen that some may have allergy from certain kind of food while others don’t get affected by it.

 Food Allergy

Let’s say for an instance, you decide to eat something that you have not tasted ever before, and it triggers a reaction. You start having breathing difficulty, your tongue gets swollen up and so does your face. You feel difficulty in speaking. The reason is that when you eat a certain food, your immune system recognizes it as a foreign body which is also termed as an allergen. The reaction of your body, in that case, is that it develops the antibodies that fight the allergens. When you eat that food again, your body again fights antibodies but also releases a chemical called histamine that leads to the allergic reaction. Sometimes, people get confused with food allergy as well as food tolerance. At one place where food allergy is eating a certain type of food that could cause some serious complications, food tolerance is less severe than that which does not involve the immune system.

What are the risk factors involved?

There are some risk factors that are linked to this kind of medical condition like:

  • Having a family history of allergy. You will be more likely to have allergies if both of your parents have it. 
  • If you have some allergic conditions like asthma, dermatitis, etc.
  • If you have some medical condition then it would make it easier for allergens to pass through the walls of the stomach and create a disturbance.
  • If you are an asthma patient

What are the symptoms involved?

For some, it could be too frightening that they need to consult the doctor immediately due to the severe symptoms. They include:

  • Swelling of throat or tongue
  • Feeling faint
  • Itching in the mouth
  • Wheezing, nasal congestion
  • Abdominal Pain
  • Trouble Breathing
  • Nausea
  • Vomiting
  • Eczema

What are some common triggers?

When you get allergic to food, then your immune system accidentally identifies a specific kind of food as a harmful substance. In its response, the immune system triggers those cells that are responsible for releasing the antibodies usually termed as immunoglobulin E which is responsible for neutralizing the allergy-causing food. Next time, when you eat the same food, your body senses it and signal your immune system to release the chemical which causes the symptoms of allergy.

Some common triggers include:

  • Shellfish like shrimp, lobster or crab
  • Fish
  • Peanuts
  • Eggs
  • Cows milk
  • Soy
  • Kiwi

What could be the complications?

Sometimes the complexity could get worse. It may lead to:

  • Eczema
  • Anaphylaxis

How to prevent?

It is always said that “Prevention is better than cure” which means If you know what are your food triggers, you could avoid those in your diet. You can also follow some steps like:

  • Keep a check on what you are eating or drinking: It is important to read the brands and check whether that food item has not exhausted its expiry date.
  • Regularly Visit Doctor: If you are at risk of severe reaction caused by allergens, it is necessary to immediately contact your doctor and get the proper diagnosis.

This is all about food allergy. Hope you get benefitted from it. Share it with your friends and family.
