Understanding Allergies in the UK: Causes, Symptoms, and Treatments
Allergies affect more than 1 in 4 people in the UK at some point in their lives, making them one of the most common chronic conditions across the populationabout Allergies. They can start in childhood and either fade or persist into adulthood—and in many cases, adults can even develop allergies later in life. Though usually mild, allergies can be life-altering and, in rare cases, life-threatening.
What Are Allergies?
An allergy is the immune system’s overreaction to substances that are typically harmless, called allergens. Common allergens in the UK include:
- Pollen (grass and tree)
- Dust mites
- Animal dander
- Food (nuts, eggs, shellfish, milk)
- Insect stings
- Medications
- Latex
- Mould
- Household chemicals

Symptoms of Allergies
Allergic reactions usually occur within minutes of exposure to an allergen. Symptoms may include:
- Sneezing and a runny or blocked nose
- Red, itchy, or watery eyes
- Wheezing or coughing
- A red, itchy rash
- Worsening asthma or eczema
- In severe cases, anaphylaxis—a potentially fatal reaction that requires immediate emergency attentionabout Allergies.
