About the clinic

Allergy medicine is fundamentally about pattern recognition. An allergy test says what the body reacts to in the test tube — but only the symptom history decides whether that actually means anything clinically. Many people test positive without having symptoms, and some have clear symptoms with negative tests. An experienced allergist therefore always puts most weight on what happens, when and how often — the test is a complement, not the answer.

We start by mapping your symptom pattern properly, because that is where the diagnosis usually lies. It means we can often point to the likely trigger long before a formal test has been done.

3Video consultation — review of your history and targeted questions.
4A clear plan — next steps, any treatment, and a timeframe for follow-up.

What to prepare

A timeline of your symptoms (when it started, what triggers or relieves it)
Current medications and doses
Known allergies and previous illnesses
Previous test results and examinations, with dates if possible
Your three most important questions for the visit

Call your local emergency number immediately or go to the nearest emergency department if you have:

Swelling of the face, lips or throat
Severe difficulty breathing after exposure to a suspected allergen
Dizziness or an altered level of consciousness alongside an allergic reaction
Rapidly spreading hives with breathing affected

Digital care cannot replace emergency services. If unsure, seek care immediately.

Frequently asked questions

Can you assess whether I have an allergy?

We make a first assessment from your symptoms and history; skin prick testing requires in-person care.

Can you follow up asthma?

Yes.

Can you prescribe allergy medication?

Yes, where it is medically appropriate.

Can you interpret an allergy test I have already had?

Yes.

What do I do about a severe allergic reaction?

If you have an adrenaline auto-injector, use it first, before calling. Then call your local emergency number if you have swelling of the face or throat, or difficulty breathing — even if the symptoms improve. See the safety box.

What happens after the appointment?

A written plan.

Can children be helped?

Yes.

What do I do if the symptoms get worse?

Can you develop an allergy as an adult?

Yes. Allergy can begin at any age, even to something you have tolerated all your life.

Does a positive allergy test mean I am allergic?

Not necessarily. The test shows sensitisation — it is the symptoms on exposure that decide whether it is a clinical allergy.

Fifteen common conditions

Allergic rhinitis

Typical age: All ages.
Background: An allergic reaction in the lining of the nose.
Symptoms: Sneezing, a blocked nose, a runny nose, itchy eyes.
What the doctor looks for: A seasonal pattern, or constant exposure.
Investigations: The clinical picture, sometimes an allergy test.
Diagnosis: The clinical picture, with or without a test.
Management: Antihistamine, nasal spray, avoiding the trigger.
Follow-up: As needed.
Prognosis: Good; it is manageable.
What you can do yourself: Start a nasal steroid two weeks before your season — preventing works considerably better than treating once the symptoms are under way.
When should you book?: When over-the-counter treatment isn't enough, or where there are asthma symptoms at the same time.

Asthma

Typical age: All ages.
Background: Chronic inflammation of the airways.
Symptoms: Wheezing, cough, breathlessness.
What the doctor looks for: Symptom control and the triggering factors.
Investigations: A symptom diary, sometimes lung function values from previous care.
Diagnosis: The clinical picture, with or without previous testing.
Management: Inhaled treatment according to a plan.
Follow-up: Regular.
Prognosis: Good control is achievable with the right treatment.
What you can do yourself: Check your inhaler technique — incorrect technique is the most common reason treatment doesn't work.
When should you book?: If your need for reliever medication increases, or if you wake at night with a cough or breathlessness.

Eczema (atopic)

Typical age: All ages; common in children.
Background: Chronic skin inflammation, often linked to allergy.
Symptoms: Dry, itchy, reddened skin.
What the doctor looks for: The extent and the pattern.
Investigations: Clinical assessment of the skin.
Diagnosis: The clinical picture.
Management: Emollients, steroid cream where needed.
Follow-up: If it gets worse.
Prognosis: Good; often chronically recurring but manageable.
What you can do yourself: Emollients daily, including on skin without symptoms — prevention makes more difference than treating the flare.
When should you book?: For eczema that doesn't respond to emollients, or where there are signs of infection.

Food allergy

Typical age: All ages; most common in children.
Background: The immune system reacts to specific foods.
Symptoms: Rash, an itchy mouth, and in serious cases swelling or breathing being affected.
What the doctor looks for: The pattern of reactions linked to particular foods.
Investigations: History; may require allergy testing through in-person care.
Diagnosis: The symptom history, with or without a test.
Management: Avoidance, with an emergency plan in serious allergy.
Follow-up: Regular.
Prognosis: Varies; children grow out of some allergies.
What you can do yourself: Keep emergency medication available and make sure the people around you know where it is.
When should you book?: For a suspected new allergy, or for follow-up before travelling or starting school.

A severe allergic reaction with swelling of the face or throat, or with breathing affected, is an emergency — see the safety box. If you have an adrenaline auto-injector, use it first, before calling. Then call your local emergency number even if symptoms improve.

Urticaria (hives)

Typical age: All ages.
Background: A histamine-driven skin reaction.
Symptoms: Raised, itchy weals that come and go.
What the doctor looks for: The extent, and the triggering factor.
Investigations: History.
Diagnosis: The clinical picture.
Management: Antihistamine.
Follow-up: If symptoms persist beyond six weeks.
Prognosis: Good; usually temporary.
What you can do yourself: Over-the-counter antihistamine helps most people; note what you were exposed to in the hours beforehand.
When should you book?: For symptoms lasting more than six weeks. For swelling of the face or throat — emergency care.

Drug allergy

Typical age: All ages.
Background: An allergic reaction to a medicine.
Symptoms: Rash, sometimes swelling or breathing being affected.
What the doctor looks for: The timing in relation to taking the medicine.
Investigations: History, and documentation in the records.
Diagnosis: The clinical picture and an assessment of the link.
Management: Avoiding the medicine, with documentation for future care.
Follow-up: As needed.
Prognosis: Good with correct identification and avoidance.
What you can do yourself: Note the exact medicine, the dose and the time of the reaction — that is what decides the assessment.
When should you book?: After every suspected reaction, so that it can be documented correctly in the records.

Immunodeficiency — investigation support

Typical age: All ages.
Background: A weakened immune system, either present from birth or acquired.
Symptoms: Recurrent or unusually severe infections.
What the doctor looks for: The pattern of infections.
Investigations: History, blood tests, often specialist investigation.
Diagnosis: Requires specialist investigation.
Management: According to the specialist plan.
Follow-up: Regular.
Prognosis: Varies with the type and the cause.
What you can do yourself: Keep an infection diary for a year — the number, the type and the treatment.
When should you book?: For unusually many, severe or drawn-out infections.

Pollen allergy

Typical age: All ages.
Background: A seasonal allergic reaction to pollen.
Symptoms: Sneezing, itchy eyes, a blocked nose during the pollen season.
What the doctor looks for: The seasonal pattern.
Investigations: The clinical picture, sometimes an allergy test.
Diagnosis: The clinical picture.
Management: Antihistamine, and possibly specific immunotherapy through a specialist.
Follow-up: As needed.
Prognosis: Good; it is manageable.
What you can do yourself: Shower and change clothes after being outdoors in peak season; keep the windows closed in the morning.
When should you book?: When the symptoms affect sleep or work despite over-the-counter treatment.

Animal allergy

Typical age: All ages.
Background: An allergic reaction to animal hair and skin flakes.
Symptoms: Sneezing, itchy eyes, breathing problems on exposure.
What the doctor looks for: The link to contact with animals.
Investigations: History, sometimes an allergy test.
Diagnosis: The clinical picture, with or without a test.
Management: Avoidance, antihistamine.
Follow-up: As needed.
Prognosis: Good with avoidance.
What you can do yourself: Keeping the bedroom animal-free is the single most effective measure if you cannot avoid the animal altogether.
When should you book?: For symptoms despite these measures, or before deciding to get a pet where allergy is known.

Contact allergy

Typical age: All ages.
Background: An allergic reaction where the skin comes into contact with a substance.
Symptoms: Redness and itching on the exposed area.
What the doctor looks for: The pattern linked to exposure.
Investigations: History, sometimes patch testing through a specialist.
Diagnosis: The clinical picture and the history.
Management: Avoidance, steroid cream.
Follow-up: If symptoms persist.
Prognosis: Good once the cause is identified.
What you can do yourself: Keep the ingredient list from any product you suspect — it is needed to identify the substance.
When should you book?: For recurrent eczema with no clear cause, for patch testing.

Anaphylaxis — prevention and readiness

Typical age: All ages.
Background: Anaphylaxis is a rapidly developing, potentially life-threatening allergic reaction. What decides the outcome is not the severity of the reaction in itself, but how quickly adrenaline is given — which makes readiness, and knowledge in the patient and the people around them, the most important treatment there is.
Common symptoms: Rapidly developing swelling of the face or throat, difficulty breathing, severe hives, a drop in blood pressure, vomiting.
What the doctor looks for: The severity of previous reactions, known triggers, and whether the patient has an adrenaline auto-injector and can use it.
Investigations: Allergy investigation to establish the trigger; a review of previous episodes.
How the assessment is made: From the description of the reaction and the risk profile.
Management: An adrenaline auto-injector, a written action plan, avoiding the known trigger.
Follow-up: An annual review of technique and that the injector has not expired.
Risk factors to know: Asthma at the same time (which raises the risk of a severe reaction considerably), previous anaphylaxis, allergy to peanuts, tree nuts, shellfish, or bee or wasp stings.
Common misconception: That you should wait and see whether the reaction passes before adrenaline is given. Delay is the most common reason for a serious outcome — adrenaline is given early, not last.
What you can do yourself: Always carry the adrenaline auto-injector, check the expiry date, and make sure family, school or workplace know where it is and how it is used.
When should you book?: After every anaphylactic reaction, and for an annual review where the risk is known. During an ongoing reaction — adrenaline first, then call your local emergency number, even if the symptoms improve.
Prognosis: Good with the right readiness.

Cross-reactivity between pollen and food

Typical age: All ages; most common in people with birch pollen allergy.
Background: Many people with pollen allergy also react to certain fruits, nuts and vegetables, because the proteins resemble each other. The reaction usually sits in the mouth and is mild — but it often causes considerable worry, because the patient believes a serious food allergy has developed.
Common symptoms: Itching in the mouth and throat, slight swelling of the lips, immediately on eating raw fruit or nuts.
What the doctor looks for: Whether the reaction is limited to the mouth, and whether the same food is tolerated cooked — both point to cross-reactivity rather than a true food allergy.
Investigations: History; sometimes component testing to distinguish cross-reactivity from a true allergy.
How the assessment is made: From where the symptoms sit and whether heat-treated food is tolerated.
Management: Avoid the raw form; cooked food is usually tolerated.
Follow-up: If the pattern of reactions changes.
Risk factors to know: Birch pollen allergy (the most common link — apple, pear, cherry, carrot, hazelnut), grass pollen (tomato, melon).
Common misconception: That cross-reactivity means a risk of anaphylaxis. The reactions are usually mild and limited to the mouth — but nuts can be an exception and should be assessed.
What you can do yourself: Test whether the same fruit is tolerated cooked — that often gives the answer straight away.
When should you book?: If the reaction spreads beyond the mouth, or if it involves nuts.
Prognosis: Good — most people can eat most things in cooked form.

Asthma that gets worse on exertion

Typical age: All ages; particularly common in children and young athletes.
Background: Exercise-induced asthma is common and often undiagnosed — many people think they are simply unfit. That leads young people to give up sport unnecessarily, even though the condition is straightforward to treat.
Common symptoms: Cough, wheezing or breathlessness five to fifteen minutes after starting to exert yourself, often worse in cold air.
What the doctor looks for: The timing after exertion begins — symptoms that only come on after a few minutes are typical.
Investigations: History; an exercise test or lung function measurement through in-person care.
How the diagnosis is made: The symptom picture plus lung function measurement.
Management: An inhaled bronchodilator before activity; maintenance treatment where symptoms are pronounced.
Follow-up: After treatment has been started.
Risk factors to know: Known asthma, allergy, eczema, cold and dry air, endurance sport.
Common misconception: That it is just poor fitness. Unfit people become breathless straight away — in exercise-induced asthma the symptoms typically come a few minutes into the activity or after it.
What you can do yourself: Warm up gradually for ten minutes — it noticeably reduces the symptoms for many people.
When should you book?: For cough or breathlessness during exercise, particularly in a child who has started avoiding sport.
Prognosis: Very good — most people can train entirely normally with the right treatment.

Hives with no known cause

Typical age: All ages; more common in women.
Background: Chronic urticaria — hives lasting more than six weeks — is often not allergic at all, despite the name. In the majority of cases no external trigger is found, and the condition is instead autoimmune. That means an extensive allergy work-up is often unnecessary while the treatment works well anyway.
Common symptoms: Itchy, raised weals that move around and disappear within a day, often coming in bouts.
What the doctor looks for: Whether individual weals last longer than 24 hours (which points to a different diagnosis) and whether there is swelling at the same time.
Investigations: A limited blood panel; an extensive allergy work-up has little value in chronic urticaria.
How the assessment is made: From the duration and how the weals behave.
Management: An increased dose of antihistamine is first-line and helps most people; specialist treatment where the effect is insufficient.
Follow-up: Once treatment has been settled.
Risk factors to know: Autoimmune thyroid disease, stress as an aggravating factor, NSAIDs (which can make it worse).
Common misconception: That there must be a food allergy behind it. In chronic urticaria a trigger is rarely found at all — and that does not mean the work-up has failed.
What you can do yourself: Photograph the weals and note how long individual ones stay — that is diagnostically valuable.
When should you book?: For hives that keep recurring beyond six weeks.
Prognosis: Good — most people are rid of it within a few years, and the treatment works in the meantime.

Bee and wasp stings — reaction and risk assessment

Typical age: All ages.
Background: Local swelling after a sting is normal and harmless, even when it is pronounced. What matters is to pick out a systemic reaction — symptoms somewhere other than the sting site — because that means a risk of anaphylaxis at the next sting and makes investigation worthwhile.
Common symptoms: Local pain, redness and swelling. In a systemic reaction: hives over the whole body, difficulty breathing, dizziness.
What the doctor looks for: Whether the reaction was purely local, or whether there were symptoms somewhere other than the sting site.
Investigations: Allergy investigation after a previous systemic reaction; not needed for purely local reactions.
How the assessment is made: From how far the reaction spread at previous stings.
Management: An adrenaline auto-injector after a previous systemic reaction; immunotherapy (desensitisation) is highly effective in pronounced insect venom allergy.
Follow-up: During ongoing immunotherapy.
Risk factors to know: A previous systemic reaction, asthma at the same time, occupational exposure (beekeepers, gardeners).
Common misconception: That pronounced local swelling means allergy and a risk of anaphylaxis. Large local swelling is unpleasant but does not mean a greater risk of a serious reaction next time — a systemic reaction does.
What you can do yourself: Cooling and antihistamine for a local reaction. After a previous systemic reaction — always carry an adrenaline auto-injector outdoors during the season.
When should you book?: After every reaction with symptoms beyond the sting site.
Prognosis: Very good — immunotherapy gives strong protection for the great majority.
