Introduction to Allergies
Allergies are hypersensitive responses from the immune system to substances that either enter or come into contact with the body. These substances, known as allergens, are typically harmless to most individuals but can trigger a reaction in susceptible individuals. Allergic reactions vary in severity from mild irritation to severe anaphylaxis, which can be life-threatening.
Common Allergens
Common allergens can be categorised into several groups:
- Environmental Allergens: These include pollen, mould spores, animal dander, and dust mites. These allergens are often airborne and can cause respiratory symptoms.
- Food Allergens: Common food allergens include nuts, shellfish, eggs, milk, and wheat. These allergens can cause gastrointestinal symptoms, skin reactions, or more severe anaphylactic responses.
- Insect Stings: Venom from insects like bees, wasps, and ants can trigger allergic reactions in some individuals, ranging from localised swelling to systemic anaphylaxis.
- Medications: Certain medications, such as penicillin or aspirin, can cause allergic reactions. These reactions can range from mild skin rashes to severe respiratory issues.
- Latex: Natural rubber latex found in products like gloves and balloons can cause allergic reactions in some people, particularly healthcare workers and individuals who undergo multiple surgeries.
Symptoms of Allergies
The symptoms of allergies depend on the type of allergen and the individual’s sensitivity to it. Common symptoms include:
- Respiratory Symptoms: Sneezing, coughing, nasal congestion, and shortness of breath.
- Skin Reactions: Hives, eczema, itching, and swelling.
- Gastrointestinal Symptoms: Nausea, vomiting, diarrhoea, and stomach cramps.
- Anaphylaxis: A severe, potentially life-threatening reaction that involves difficulty breathing, a drop in blood pressure, and loss of consciousness.
Mechanism of Allergic Reactions
The immune system plays a crucial role in allergic reactions. When an allergen enters the body, it binds to immunoglobulin E (IgE) antibodies on the surface of mast cells and basophils. This binding triggers the release of histamine and other inflammatory mediators. These chemicals cause the symptoms associated with allergic reactions, such as swelling, redness, and mucus production.
Diagnosis and Management
Allergies are diagnosed using a combination of patient history, physical examinations, and diagnostic tests like skin prick tests and blood tests. Management typically involves:
- Avoidance: Steering clear of known allergens is the most effective way to prevent allergic reactions.
- Medications: Antihistamines, corticosteroids, and decongestants can alleviate symptoms.
- Immunotherapy: Allergy shots or sublingual tablets can desensitise the immune system to specific allergens over time.
Understanding the basics of allergies is essential for effective management and improving quality of life for those affected.
What Causes Allergies?
Allergies are triggered by a hyperactive response of the immune system to substances that are typically harmless to most people. These substances are known as allergens. The immune system mistakenly identifies these allergens as dangerous, prompting the production of antibodies called Immunoglobulin E (IgE). These antibodies travel to cells that release chemicals, causing an allergic reaction.
Common Allergens
- Pollen: Produced by trees, grasses, and weeds. It is most prevalent during spring and fall.
- Dust mites: Microscopic organisms that thrive in house dust and are commonly found in bedding and upholstered furniture.
- Pet dander: Proteins found in the skin cells, urine, and saliva of pets. Cats and dogs are typical sources.
- Mould spores: Fungi that grow indoors and outdoors in damp environments.
- Food: Common food allergens include peanuts, tree nuts, shellfish, dairy products, and eggs.
- Insect stings: Venom from insects like bees, wasps, and ants.
- Medications: Some individuals react to certain drugs, like penicillin or aspirin.
- Latex: Found in products such as gloves, balloons, and condoms.
The Role of Genetics
- Family History: An individual is more likely to develop allergies if there is a family history of allergies, asthma, or atopic dermatitis.
- Genetic Predisposition: Specific genes can make one more susceptible to allergies.
Environmental Factors
- Exposure to Allergens: Early exposure, particularly in childhood, can increase the risk of developing allergies.
- Pollution: Air pollution and tobacco smoke can heighten sensitivity to allergens.
- Hygiene Hypothesis: Suggests that a lack of early childhood exposure to infectious agents and microorganisms increases susceptibility to allergic diseases by suppressing the natural development of the immune system.
Development of Sensitisation
- Initial Exposure: The body’s first contact with an allergen often goes unnoticed, as the immune system becomes sensitised.
- Subsequent Exposures: Future encounters with the allergen trigger a full-blown allergic reaction involving the release of histamines and other chemicals.
Understanding the causes of allergies can help in managing symptoms and reducing exposure to allergens. Identifying triggers through tests like skin prick tests or blood tests can aid in crafting an effective management plan.
Common Allergy Triggers
Allergy triggers, also known as allergens, are substances that can cause allergic reactions. These reactions occur when the immune system responds abnormally to these typically harmless substances. Understanding common allergy triggers can help in identifying and managing allergies more effectively.
Airborne Allergens
Airborne allergens are among the most common triggers of allergic reactions.
- Pollen: The fine powdery substance released by plants, especially from trees, grasses, and weeds, during their reproductive cycle.
- Dust Mites: Tiny insects that thrive in household dust. Their body parts and waste products can become airborne, causing allergic reactions.
- Mould Spores: Fungi that release spores into the air, prevalent in damp environments, such as bathrooms and basements.
- Pet Dander: Tiny, even microscopic, flecks of skin shed by cats, dogs, rodents, birds, and other animals with fur or feathers.
- Cockroach Droppings: Proteins found in cockroach feces, saliva, and body parts can trigger allergies in some individuals.
Food Allergens

- Applying patches containing potential allergens onto the skin, usually the back.
- Leaving the patches in place for 48 hours.
- Reviewing the skin for any reactions 48 to 72 hours after application. This test is particularly useful for identifying contact dermatitis allergens.
Blood Tests
Blood tests, such as the Radioallergosorbent Test (RAST) or ImmunoCAP, measure specific IgE antibodies in the blood. These include:
- Drawing a blood sample from the patient.
- Analysing the sample in a laboratory to identify elevated levels of IgE antibodies related to specific allergens.
- Offering an alternative to skin testing, especially for individuals with skin conditions or those taking medications that could interfere with skin tests.
Challenge Tests
Challenge tests are conducted under close medical supervision and involve:
- Administering a small amount of the suspected allergen orally or through inhalation.
- Monitoring the patient for any allergic reaction. This test is particularly informative for diagnosing food or drug allergies but carries a higher risk and requires specialised settings.
Elimination Diets
Elimination diets are recommended for food allergies and involve:
- Removing suspected allergenic foods from the diet for a specified period.
- Gradually reintroducing foods one at a time and observing any allergic responses.
- Identifying specific food triggers through careful monitoring and documentation of symptoms.
Quote: To ensure accurate diagnosis, patients need to provide a detailed medical history, including symptom descriptions and potential exposure to allergens.
Different tests offer varying degrees of sensitivity and specificity. Selection depends on the patient’s symptoms, history, and type of allergy suspected.
Treatment Options for Allergies
