5 COMMON ALLERGY TRIGGERS

An allergy is an immune system response to a foreign substance that’s not typically harmful to your body. These foreign substances are called allergens. They can include certain foods, pollen, or pet dander.

Your immune system’s job is to keep you healthy by fighting harmful pathogens. It does this by attacking anything it thinks could put your body in danger. Depending on the allergen, this response may involve inflammation, sneezing, or a host of other symptoms.

Below are five common allergy triggers;

Your Overactive Immune System

Many things can trigger an allergic reaction. It happens when your body’s defenses attack something that’s usually harmless, such as pollen, animal dander, or food. The reaction can range from mild and annoying to sudden and  life-threatening. In the US, about 30% of all adults and 40% of children have allergies.

Pollen

It comes from plants such as grasses, trees, and weeds and can trigger hay fever or seasonal allergies. You might sneeze and have a runny or stuffy nose and itchy, watery eyes. Treat these with over-the-counter products, prescription drugs, and allergy shots. To help prevent symptoms, stay inside on windy days when pollen counts are high, close windows, and run the air conditioning.

Insect Stings

These could cause swelling and redness that may last a week or more. You might feel sick to your stomach and tired and have a low fever. In rare cases, insect bites trigger a reaction that can be life-threatening, called anaphylaxis. If you’re severely allergic, you’ll need medicine called epinephrine right away. Your doctor may recommend allergy shots to prevent reactions.

Food

Milk, shellfish, eggs, and nuts are among the most common foods that cause allergies. Others include wheat, soy, and fish. Within minutes of eating something you’re allergic to, you could have trouble breathing and get hives, vomiting, diarrhea, and swelling around your mouth. If your reaction is severe, you will need emergency medical help. 

Medication

Penicillin, aspirin, and other drugs can cause hives, itchy eyes, stuffiness, and swelling in your face, mouth, and throat. If you’re allergic to a drug, it’s best to not take it. Your doctor can talk to you about other medicine options or treatments that may allow you to take a medicine if it’s necessary.

Allergies are common and don’t have life-threatening consequences for most people. People who are at risk of anaphylaxis can learn how to manage their allergies and what to do in an emergency situation.

Most allergies are manageable with avoidance, medications, and lifestyle changes. Working with your doctor or allergist can help reduce any major complications and make life more enjoyable.
