You may notice a sudden rash, redness, or itching that can occur out of nowhere. This could probably be a sign of an allergic reaction. While the problems may seem to start in the nose, or the eyes, allergies actually occur when your immune system is disrupted. Learning about these reactions can help you keep things under control and feel better.

An insight into an allergic reaction

An allergic reaction is a set of symptoms that occur due to the way your body reacts to an allergen (foreign substance).  Your immune system activates your body’s defense mechanism which creates antibodies to form immunoglobulins. These antibodies find the allergens in your body and help remove them by attaching them to the mast cells (allergy cells) through special receptors. This leads to the release of histamines that cause the allergic symptoms.

Allergic reactions can exhibit the following symptoms 

The symptoms of an allergic reaction can vary from mild to severe. These have been listed below.

Mild symptoms 

  • Skin rash
  • Itching and hives 
  • Allergic rhinitis leading to nasal congestion
  • Scratchy throat
  • Itchy, and watery eyes

Severe symptoms 

  • Abdominal cramps 
  • Diarrhea 
  • Nausea or vomiting
  • Chest pain or tightness
  • Wheezing
  • Breathing difficulties
  • Palpitations
  • Difficulty swallowing 
  • Flushing of the face
  • Swelling around the eyes and lips
  • Dizziness or vertigo
  • Weakness
  • Sudden drop in blood pressure 
  • Unconsciousness 

Common allergens that cause negative reactions in your body:

  • Insect bites
  • Bee stings
  • Nuts
  • Shellfish
  • Pet dander 
  • Penicillin, aspirin, or other medicines 
  • Some plants 
  • Mold 
  • Pollen 
  • Dust mites 
  • Latex allergies 

Treating allergic reactions 

It is essential to determine the cause of the allergic reaction and to design an appropriate treatment plan. This is possible through a skin prick test, blood tests, and a combination of other allergy tests.

Treatment for allergic reactions depends on the cause and severity of the symptoms. Allergic reactions are addressed best by ER (emergency room) physicians and nurses. Your physician will opt for the following methods to manage the reactions:

  • Watchful waiting 
  • Medications in the form of oral pills, nasal sprays, or eye drops
  • Epipheprine shot 
  • CPR (in severe cases )


Allergic reactions occur when your immune system triggers a negative reaction to an allergen (foreign body). These reactions vary in severity and may be mild, or severe. 

Allergic reactions can be incredibly frustrating if you do not know the cause that triggers your immune system. Seek medical help to pinpoint the exact cause of your allergies, which facilitates prompt treatment.
