Allergies and food intolerances affect a significant proportion of the population, and the symptoms they cause can range from mildly inconvenient to seriously disruptive. At The Wright Practice, Dr Dan Wright offers comprehensive allergy and food intolerance testing to identify what is causing your symptoms and provide a clear management plan.
A food intolerance involves the digestive system’s inability to process certain foods properly. Symptoms are usually gastrointestinal: bloating, diarrhoea, wind, and abdominal discomfort.
Lactose intolerance and non-coeliac gluten sensitivity are common examples. Food intolerances are not life-threatening, but they can significantly affect quality of life.
A food allergy involves the immune system. When an allergic person is exposed to a trigger food or allergen, the immune system mounts an exaggerated response. Symptoms can include hives, itching, facial swelling, breathing difficulties, and in severe cases, anaphylaxis. Food allergies to peanuts, eggs, shellfish, wheat, milk, and seeds are increasingly common.
Environmental allergies, including hay fever, dust mite allergy, and allergic reactions to insect stings, also involve immune responses and can range from mild to severe.

Identifying what is triggering your symptoms allows you to manage them effectively. Without a clear diagnosis, many patients spend years avoiding the wrong foods or failing to address the actual cause. Proper testing also establishes the severity of any reaction, which is important for deciding whether you should carry an adrenaline auto-injector.
Around 30% of the population experiences some form of allergy at some point. Hay fever affects more than 15% of people, and food allergy prevalence is rising across all age groups.

Dr Dan will take a detailed history of your symptoms, including when they occur, what appears to trigger them, their severity, and how they affect your daily life. Based on this, he will recommend the appropriate tests, which may include blood testing for specific IgE antibodies (true allergy) or IgG antibodies (intolerance), and in some cases a specialist referral for skin prick testing or drug challenge.
Results will be discussed in a follow-up consultation, with a clear plan for avoiding triggers, managing symptoms, and where relevant, carrying emergency medication.
Allergy and intolerance testing at The Wright Practice is part of a thorough, whole-person assessment. Dr Dan does not simply send a test panel and leave you to interpret the results. He explains findings in the context of your symptoms and history and gives you a practical management plan. Where a reaction is severe or complex, he will refer you to a specialist allergist.

Wow! Dr. Dan was extremely knowledgeable and attentive to my health and well being. I’m so glad to have found him!
I have been going to Dr Wright for a number of years now. He is highly knowledgeable, compassionate, open minded and efficient, I couldn’t recommend him highly enough
I have been a patient of Doctor Dan for some time and continue to consult with him despite having left the UK. Dan has the enthusiasm and energy of a young man, whilst taking the holistic “physician” approach of an old school family doctor, equipped with the most modern insights and technology.
Dr Jain was great. Expert knowledge with practical advice
Food intolerance symptoms include bloating, diarrhoea, wind, and stomach pain after eating. Allergy symptoms can include hives, itching, sneezing, facial swelling, and breathing difficulties. Persistent fatigue and eczema can also be allergy-related.
Yes. Blood testing for specific pollen, dust mite, and animal dander IgE antibodies can identify the environmental allergens causing hay fever and allergic rhinitis symptoms.
Blood testing for coeliac disease is available. If the result is positive or inconclusive, Dr Dan will arrange a specialist referral for confirmatory biopsy, which is required for a definitive diagnosis.
If you have had a severe reaction including throat tightening or difficulty breathing, seek emergency medical care immediately. For less severe reactions, book a consultation with Dr Dan as soon as possible.
Yes. Drug allergy assessment is available. If you have had a reaction to a medication, Dr Dan will assess the nature of the reaction and refer to a specialist allergist for formal testing where needed.
For blood-based allergy tests, antihistamines do not need to be stopped. For skin prick testing via specialist referral, antihistamines should be stopped several days before the test.
Blood-based allergy tests typically return results within five to seven working days. Dr Dan will review the results and discuss them in a follow-up appointment.
The practice primarily sees adult patients. For children’s allergy testing, Dr Dan can provide initial assessment and refer to a paediatric allergist where appropriate.
