What is an allergy?
An allergy occurs when your immune system reacts abnormally to a substance that is typically harmless to most people. These substances, known as allergens, can be found in everyday items like pollen, animal dander, or certain foods such as nuts, fruit, or shellfish.
Typical symptoms
Allergic reactions vary from person to person. In most cases, they cause mild irritation, such as sneezing, a runny or blocked nose, itchy eyes, coughing, and an itchy rash. However, in some cases, allergic reactions can be more severe, leading to breathing difficulties or even anaphylaxis which can lead to anaphylactic shock.
When to see a health professional
Allergic symptoms can sometimes overlap with other conditions. If you're unsure whether your symptoms are due to an allergy, a GP or ACP can help. For mild allergies, our clinicians can offer advice and treatment. In cases of more severe reactions, or if the cause of the allergy is unclear, we can refer you to an allergy specialist for further tests.
