How Can You Tell If You Have an Allergy

How Can You Tell If You Have an Allergy

Causes

Allergies occur when your body overreacts to remove an allergen like certain food, air particles, drugs/medications, contacted substances, and insect bites/stings.

Limited childhood allergen exposure and predisposition to asthma can cause allergies later.

Symptoms

While fever is never an allergy symptom, per the ACAAI, here are the most common ones:

1. Nausea/Vomiting

Nausea and vomiting are rarely caused by seasonal allergies, but rather food allergies to fish, shellfish, soy, wheat, nuts, milk, and eggs.

Additional symptoms include hives, coughing, difficulty breathing/swallowing, and more.

2. Rashes

Rashes can stem from food allergies, drug allergies, allergies to physical factors, insect bites/stings, and viral infections.

Allergic rashes usually fall into three cases: contact dermatitis, eczema, or hives.

Eczema, or atopic dermatitis, occur as periodic, long-lasting flare-ups of small raised bump, dry skin, or scaly skin patches.

Typically resulting from an allergy or virus, hives, or urticaria, are sudden, temporary outbreaks of welts and/or skin bumps.

3. Coughing

Allergies and asthma typically cause chronic dry coughing for more than three weeks.

While allergies and asthma can have common causes, allergic coughing happens frequently in certain environments and seasons with other allergy symptoms, whereas asthmatic coughing appears as infrequent, sudden attacks.

Common causes are pollen, mold, pet dander, dust mites, cockroaches, and other allergens.
