Common Allergy Symptoms That You Should Know About

An allergy occurs when your body’s immune system overreacts to something that is harmless to most people by releasing a chemical called histamine to counteract it.

When histamine gets released into the body, it can cause a variety of symptoms. The symptoms will vary depending on the type of allergen. If the allergen is something you breathe in from the air, such as dust mites or pollen, the reaction will most likely affect around your eyes, nose and lungs. If it is something you eat such as foods or drugs, it may affect your mouth, stomach and intestines. Allergies can cause skin rashes or even asthma symptoms. In the most serious cases, a life-threatening reaction called Anaphylaxis can also occur.

Some of the common allergy symptoms include:

  • Itchy eyes
  • Itchy skin
  • Sneezing
  • Wheezing
  • Runny nose
  • Nasal congestion

  • Hives (a rash with raised red patches)
