Signs That You Have an Allergic Reaction

An allergic reaction is a form of exaggerated sensitivities that occurs when your immune system responds abnormally to ordinary substances such as dust, certain food, or pollen. The reaction happens when your immune system sees certain substances as harmful while they may not be. There are several types of allergies; some may be seasonal while others occur indefinitely. It is vital to work with your healthcare provider to plan to protect and manage your allergies. Dr. Hiral Thakrar in Gilbert provides customized treatment and specialized services to suit your unique treatment needs.

Types of allergies that you are likely to experience

There are several forms of allergic reactions that you are likely to experience. Some of these include;

Type I or Anaphylactic reactions; this type of allergic reaction is mediated by IgE antibodies produced by your immune system. This happens when you ingest allergens such as pollen, dust, animal dander, or even certain types of food. Ingestion will cause your body to release histamine or other chemicals that cause swelling or inflammation. Examples of some allergic reactions include; bronchial asthma, allergic dermatitis, food allergies, eye inflammation, and anaphylaxis. Anaphylaxis is severe and life-threatening. If you experience this, you will likely have difficulty breathing, low blood pressure, swelling, shock, or bluish skin.

Type II or Cytotoxic reactions; is a reaction mediated by proteins called IgH and IgM antibodies. This condition results from the damage of cells by antibodies, activating a component of immunity known as the complement system. Some of the conditions you are likely to experience if you have this form of a reaction include; immune thrombocytopenia, autoimmune hemolytic anemia, and autoimmune neutropenia.

Type II or Immune Complex reactions; is a type of allergic reaction mediated by proteins such as IgG and IgM. When you are experiencing this, your antibodies react and form antigen-antibody complexes. These complexes are responsible for the reaction that you are likely to experience. Conditions that you are likely to experience include lupus, serum sickness, and Arthur’s reaction.  

Type IV or Cell-mediated reactions; refers to a delayed type of allergic or hypertensive reaction that occurs several hours after being exposed to allergens. This implies that you are likely to experience this reaction after 48-72 hours. The most common type of these reactions is associated with skin sensitivity to metals.

What triggers allergic reactions?  

Allergic reactions occur when you ingest substances that trigger them. These substances are called allergens. Some common types of allergens include;

  • Pollen
  • Dust mites
  • Bee/wasp stings
  • Anima/pet dander
  • Rubber or latex
  • Specific medications such as penicillin-based medication
  • Certain foods, like eggs, peanuts, milk, wheat, or fish
  • Mold
  • Specific metals
  • Some plants


If it is evident that you have an allergic reaction, your doctor may recommend some medications depending on your allergy. The medications help to reduce the reactions in your immune system to ease the symptoms. If less severe, your doctor can recommend over-the-counter prescriptions, nasal spray, or eye drops. If severe, your doctor will recommend immunotherapy or emergency epinephrine. However, the best way to manage allergic reactions is to avoid the allergen. Your doctor will assist you in identifying and avoiding your allergens.
