What is allergies?

An allergy is the body's reaction to something usually harmless — like pollen, dust, animal fur, or certain foods. Symptoms range from mild (sneezing, itching, rash) to severe (breathing difficulty, anaphylaxis). Most allergies can be managed with avoidance, antihistamines, and steroid sprays or creams. Severe reactions need immediate treatment with adrenaline.

Self-care information from NHS

  • Follow these steps if you think you or someone you're with is having an anaphylactic reaction.
  • Use an adrenaline auto-injector (such as an EpiPen) if you have one – instructions are included on the side of the injector.
  • Call 999 for an ambulance and say that you think you're having an anaphylactic reaction.
  • Lie down – you can raise your legs, and if you're struggling to breathe, raise your shoulders or sit up slowly (if you're pregnant, lie on your left side).
  • If you have been stung by an insect, try to remove the sting if it's still in the skin.
  • If your symptoms have not improved after 5 minutes, use a 2nd adrenaline auto-injector.
  • Do not stand or walk at any time, even if you feel better.
  • There are different types of adrenaline auto-injectors and each one is given differently.

Common questions

How do I know if I have an allergy?

Common signs include sneezing, runny or blocked nose, itchy eyes, rashes, hives, or stomach symptoms after exposure to something. A GP can assess symptoms, and testing (skin prick or blood tests) can confirm the trigger if needed.

What's the difference between an allergy and intolerance?

An allergy involves the immune system and can cause immediate, sometimes severe reactions. An intolerance (like lactose intolerance) doesn't involve the immune system — symptoms are usually digestive and take longer to develop.

What is anaphylaxis?

Anaphylaxis is a severe, life-threatening allergic reaction. Signs include swelling of the face or throat, difficulty breathing, wheezing, a rapid pulse, and collapse. Call 999 immediately and use an adrenaline auto-injector (EpiPen) if prescribed.
