When to See an Allergist: A Guide for Parents and Patients
Allergic conditions affect approximately one-third of the UK population, but knowing when to consult a specialist can be challenging. While your GP provides excellent care for many allergic conditions, certain situations benefit from the expertise of an allergist – a doctor specialising in diagnosing and treating allergies, asthma, and related immune system disorders.
Understanding the role of an allergist
Allergists have specialised training that enables them to:
- Identify specific allergens triggering your or your child's symptoms
- Distinguish between different types of allergic and non-allergic reactions
- Create comprehensive management plans for complex allergic conditions
- Provide specialised treatments not typically available through primary care
- Recommend preventive strategies based on the latest research
At LACK Clinic, our approach combines pioneering research with personalised care to address the unique challenges of each patient's allergic condition.
When to consider specialist allergy care for eczema
Eczema (atopic dermatitis) affects up to 20% of children and 10% of adults in the UK. While mild cases can often be managed by your GP, several situations warrant consultation with an allergist:
Early-onset eczema
If your baby develops eczema within the first six months of life, an allergist can provide crucial early intervention. Research shows that early-onset eczema, particularly when moderate to severe, significantly increases the risk of developing food allergies. Early specialist care may help prevent this progression.
Treatment-resistant eczema
Consider specialist referral if:
- Regular moisturising and prescribed treatments aren't controlling symptoms
- Your child needs frequent courses of topical steroids
- The condition is causing significant sleep disruption or distress
Eczema with suspected allergic triggers
An allergist should evaluate eczema that:
- Flares consistently after certain foods
- Shows seasonal variations suggesting environmental allergen triggers
- Appears alongside other allergic symptoms
Our specialists can identify specific triggers through appropriate testing and develop targeted management strategies that address both the skin condition and potential allergic causes.
When to seek specialist care for food allergies
Food allergies affect approximately 7-8% of children and 2% of adults. The expertise of an allergist is particularly valuable in these situations:
Multiple food allergies
Managing restrictions to several foods requires careful nutritional planning and periodic reassessment. An allergist can help:
- Confirm which allergies are genuine through appropriate testing
- Identify foods that might be unnecessarily avoided
- Monitor for potential outgrowing of allergies
- Provide guidance on maintaining balanced nutrition despite restrictions
Food allergy with asthma
This combination increases the risk of severe reactions. An allergist will:
- Develop a comprehensive management plan addressing both conditions
- Provide education on early recognition of concerning symptoms
- Create an emergency action plan tailored to your specific situation
Preparing for pregnancy with food allergies
If you have food allergies and are planning pregnancy, specialist advice can help:
- Optimise management of your allergies during pregnancy
- Discuss strategies that may reduce your baby's risk of developing allergies
- Plan for safe breastfeeding if you have food allergies
Suspected food allergy in infants
Early, accurate diagnosis is crucial. An allergist can:
- Determine whether symptoms truly indicate food allergy
- Guide appropriate introduction of allergenic foods
- Implement prevention strategies based on the latest research
When to consult an allergist for respiratory conditions
Asthma requiring specialist input
Consider allergist consultation for asthma that:
- Is severe or difficult to control
- Requires frequent courses of oral steroids
- Significantly impacts daily activities or sleep
- Has clear allergic triggers requiring identification
Allergic rhinitis (hay fever) that affects quality of life
Seek specialist care if you or your child experiences:
- Symptoms not adequately controlled by over-the-counter or prescribed medications
- Significant impact on sleep, concentration, or daily activities
- Interest in immunotherapy (desensitisation treatment)
- Need for long-term management strategies
Persistent or recurrent sinusitis
Consult an allergist if you experience:
- Sinus infections lasting more than 12 weeks
- Four or more sinus infections annually
- Symptoms that persist despite multiple courses of antibiotics
- Sinus symptoms with suspected allergic triggers
When to seek urgent allergist care
After anaphylaxis
If you or your child has experienced anaphylaxis (a severe, potentially life-threatening allergic reaction), prompt assessment by an allergist is essential. This includes reactions to:
- Foods
- Medications
- Insect stings or bites
- Unknown triggers
An allergist will:
- Identify the specific cause through appropriate testing
- Prescribe emergency medication and create an action plan
- Provide comprehensive education on avoiding triggers
- Consider whether immunotherapy might be appropriate (for certain triggers)
Severe allergic reactions to medications
Consult an allergist if you've had a significant reaction to a medication, particularly if:
- You're likely to need that medication or similar ones in the future
- Alternative medications are limited or less effective
- The reaction was severe or involved multiple symptoms
- The specific medication causing the reaction isn't clear
Other situations requiring allergist consultation
Chronic urticaria (hives)
Seek specialist assessment for hives that:
- Last more than six weeks (chronic urticaria)
- Are severe or significantly impact quality of life
- Appear alongside other allergic symptoms
- Are suspected to be triggered by specific foods or medications
Severe allergic conjunctivitis
Consider specialist care for eye allergy symptoms that:
- Aren't adequately controlled by prescribed medications
- Significantly affect vision or daily activities
- Occur alongside other allergic conditions
Insect sting or bite reactions
Consult an allergist if you've experienced:
- Large local reactions (extensive swelling)
- Systemic reactions affecting areas beyond the sting site
- Any reaction causing breathing difficulties or dizziness
Benefits of early specialist consultation
Seeking specialist advice early in the course of allergic conditions offers several advantages:
Accurate diagnosis
Allergists have access to advanced diagnostic tools not typically available in primary care, including:
- Component-resolved diagnostics
- Challenge testing under controlled conditions
- Specialised blood tests for complex cases
Prevention of disease progression
Early intervention guided by an allergist may help:
- Prevent the "allergic march" – the tendency for allergic conditions to progress from eczema to food allergies to respiratory allergies
- Reduce the risk of developing additional allergies
- Minimise the long-term impact of allergic conditions
Comprehensive care
An allergist provides:
- Coordinated management of multiple allergic conditions
- Education on allergen avoidance and symptom recognition
- Regular monitoring and adjustment of treatment plans
- Access to the latest research and treatment options
What to expect at your first allergist appointment
Your initial consultation will typically include:
Detailed history
The allergist will discuss:
- Your or your child's symptoms and their pattern
- Family history of allergic conditions
- Environmental factors that may influence symptoms
- Previous treatments and their effectiveness
Physical examination
This may focus on:
- The skin, especially for patients with eczema or hives
- The respiratory system for those with asthma or hay fever
- Other relevant systems depending on your symptoms
Diagnostic testing
Depending on your situation, the allergist may recommend:
- Skin prick testing
- Blood tests for specific IgE antibodies
- Lung function tests for respiratory symptoms
- Patch testing for suspected contact allergies
Treatment planning
Together with your allergist, you'll develop a management plan that may include:
- Medications tailored to your specific condition
- Environmental modification strategies
- Allergen avoidance guidance
- Consideration of immunotherapy if appropriate
Finding the right specialist care
When seeking an allergist, consider:
- Qualifications and specialisation in your particular allergic condition
- Experience with your age group (paediatric or adult)
- Approach to patient care and communication style
- Accessibility and availability for follow-up care
At LACK Clinic, led by Professor Gideon Lack, we combine world-leading expertise in allergy research with compassionate, patient-centred care for both children and adults.
Taking the next step
While many allergic conditions can be effectively managed by GPs, specialist care provides particular benefit in complex cases, severe reactions, or when quality of life is significantly affected.
If you or your child are experiencing any of the situations described in this article, consider discussing a referral to an allergist with your GP. Alternatively, many allergy specialists accept self-referrals for private consultations.
Remember that early, expert intervention can not only provide relief from current symptoms but may also positively influence the long-term course of allergic conditions, potentially preventing progression to more severe or additional allergies.
By understanding when specialist care is appropriate, you can make informed decisions about the best approach to managing allergies for yourself or your child, ensuring the most effective treatment and the best possible quality of life.
