Condition

Allergies

Allergy and intolerance are different things with different mechanisms and different tests. A great deal of money is spent in India on panels that cannot tell you what they claim to.

Allergy is
An immune (IgE) reaction
Intolerance is
Not immune — usually digestive
Reliable tests
Skin prick, specific IgE
Unreliable
IgG food sensitivity panels

An allergy is an immune reaction, usually rapid and IgE-mediated; an intolerance is not immune and is usually digestive. Skin prick tests and specific IgE blood tests are reliable when interpreted with the clinical history. IgG food sensitivity panels are not recommended by allergy bodies and routinely produce false positives.

Symptoms of allergies

Symptoms vary, and few people have all of them. These are the ones most commonly reported.

Sneezing and a runny noseTypical of allergic rhinitis
Itchy, watery eyesOften seasonal
Itching or hivesWithin minutes of exposure
Swelling of lips, face or tongueRequires urgent assessment
Wheeze or breathlessnessWhere the airway is involved
Vomiting or abdominal painIn food allergy
Eczema flaresOften associated in children
AnaphylaxisRapid, multi-system — a medical emergency

2-minute check

Allergy or intolerance?

Four questions. Your result appears immediately — we do not ask for an email.

How soon after exposure do symptoms start?

What kind of symptoms?

Does a tiny amount cause it?

Does it happen every single time?

When to see a doctor

Arrange a medical appointment rather than waiting if you have:

  • Swelling of the lips, tongue, face or throat — emergency
  • Difficulty breathing or swallowing — emergency
  • Any previous severe reaction — you may need an adrenaline auto-injector
  • Suspected food allergy in a child
  • Before removing a major food group long term

What causes allergies

The distinction matters because it determines the test, the treatment and the seriousness.

Step 1 The immune system sensitises

It produces IgE antibodies to a harmless protein.

Step 2 Re-exposure occurs

The allergen binds those antibodies.

Step 3 Mast cells release histamine

Rapidly, usually within minutes.

Step 4 Symptoms follow

From itching and sneezing to, rarely, anaphylaxis.

Risk factors

  • A family history of allergy, asthma or eczema
  • Existing asthma or eczema
  • Early-life antibiotic exposure
  • Urban living and air pollution
  • Delayed introduction of allergenic foods in infancy
  • Occupational exposures

How allergies is diagnosed

Tests commonly used, and what each one shows
TestWhat it indicates
Detailed clinical historyThe most important part — tests mean little without it
Skin prick testingReliable for IgE-mediated allergy
Specific IgE blood testWhere skin testing is impractical
Supervised oral food challengeThe definitive test for food allergy
Elimination and reintroductionFor suspected intolerance, done properly
Coeliac serologyBefore removing gluten — testing is invalid afterwards

Not sure which of these you have had?The assessment asks, and tells you which are worth requesting.

What happens if it is left untreated

Stated factually, because these risks are real and manageable rather than inevitable.

  • Anaphylaxis, which can be fatal
  • Unnecessary dietary restriction and consequent deficiency
  • Poor growth in children on over-restricted diets
  • Anxiety around eating and social situations
  • Poorly controlled asthma where allergy is untreated

How Health Total treats allergies

Our protocol runs alongside whatever your doctor has prescribed. We do not ask anyone to stop medication.

  1. 1

    Separate allergy from intolerance

    They have different mechanisms, different tests and very different levels of risk.

  2. 2

    Use tests that are actually validated

    IgG food sensitivity panels are not recommended by allergy societies and generate long lists of false positives.

  3. 3

    Test for coeliac before removing gluten

    Testing becomes unreliable once gluten has been removed, and the diagnosis matters.

  4. 4

    Restrict narrowly and temporarily

    Removing a long list of foods causes real nutritional harm, particularly in children.

  5. 5

    Replace what is removed

    If dairy goes, calcium has to come from somewhere. This is routinely forgotten.

What makes this different

A standard diet plan

  • A commercial IgG sensitivity panel
  • A long list of foods removed at once
  • Gluten removed before coeliac testing
  • Nothing replaced nutritionally

How we do it

  • Validated testing, read with the history
  • Narrow, temporary, structured elimination
  • Coeliac excluded first
  • Calcium and nutrients actively replaced

Nine questions. Two minutes.You will see your result before we ask for your name.

Audited results

Publication pending. Aggregate outcome figures for this condition — sample size, inclusion criteria, mean and median change, range and dropout rate — will appear here once the audited outcome report is complete and signed by a second clinician.

Under the ASCI Healthcare Guidelines, a success rate, timeline or efficacy claim requires peer-reviewed data or the organisation’s own audited outcome report. We would rather publish nothing here than publish a number we cannot substantiate.

Case studies

De-identified clinical records — the plan as delivered, the markers as measured, and adherence as it actually was. Each signed by the supervising clinician and verified by a second.

Questions we are asked

Are food sensitivity blood tests reliable?

The IgG panels widely sold in India are not recommended by allergy societies. IgG indicates exposure rather than intolerance, so the tests reliably produce long lists of everyday foods and lead to unnecessary restriction. We do not use them and would advise against paying for one.

What is the difference between allergy and intolerance?

Allergy is an immune reaction, usually within minutes, triggered by even small amounts, and it can be dangerous. Intolerance is not immune, usually digestive, generally dose-dependent, and uncomfortable rather than dangerous.

Should I remove gluten to see if I feel better?

Get tested for coeliac disease first. Once gluten is removed, coeliac testing becomes unreliable, and coeliac is a diagnosis with long-term consequences that matters to have confirmed.

Can allergies be outgrown?

Many childhood milk and egg allergies are outgrown. Peanut, tree nut and shellfish allergies are more often lifelong. Re-assessment over time is worthwhile and should be done under supervision.
