Allergic Asthma: The link between allergens and Asthma

Allergic Asthma: Causes, Symptoms, and Management

Allergic asthma is a prevalent condition in Australia, affecting a significant portion of the population. Understanding its causes, symptoms, and management strategies is crucial for those impacted. This article provides an overview of allergic asthma, its triggers, and effective management techniques.

Understanding Allergic Asthma

What is Allergic Asthma?

This is a type of asthma triggered by allergens such as pollen, dust mites, pet dander, and mould. It differs from other asthma types in that it is directly related to allergic reactions. Approximately 80% of individuals with asthma have positive allergy test results, indicating a strong link between allergies and asthma.

Causes of allergy induced asthma

How Allergies Trigger Asthma

When individuals with allergic asthma encounter specific allergens, their immune system overreacts, leading to inflammation and narrowing of the airways. This response results in asthma symptoms such as wheezing and shortness of breath. Managing exposure to these allergens is key to controlling asthma symptoms.

Symptoms of Allergic Asthma

Common Symptoms

• Wheezing

• Shortness of breath

• Chest tightness

• Coughing, especially at night or early morning

Severe Symptoms

• Difficulty breathing

• Bluish lips or face

• Rapid breathing

• Inability to speak in full sentences

Common Allergens That Trigger Asthma

Indoor Allergens

• Dust mites

• Pet dander

• Mould

Outdoor Allergens

• Pollen from trees, grasses, and weeds

• Air pollution

Food Allergens

• Peanuts

• Tree nuts

• Shellfish

• Eggs

• Milk

Tips on how to control allergens

• Use allergen-proof bedding covers

• Keep pets out of bedrooms

• Regularly clean and vacuum with a HEPA filter

• Use air purifiers to reduce airborne allergens

• Limit outdoor activities during high pollen seasons

• Avoid smoking and exposure to secondhand smoke

Allergy Testing for Asthma

Importance of Allergy Testing

Identifying specific allergens through testing helps in tailoring an effective asthma management plan. It enables individuals to avoid triggers and use appropriate medications

Types of Allergy Tests

Skin Prick Test: Involves placing a small amount of allergen on the skin and lightly pricking it to observe reactions. Results are typically available within 20 minutes.

Blood Test: Measures the level of specific IgE antibodies to allergens.

Preparing for Allergy Testing

• Avoid antihistamines for several days before the test

• Inform your doctor of any current medications

• Wear clothing with easy access to your forearms or back

Treatments for Allergic Asthma

Allergic Asthma Medications

• Relievers (Short-acting bronchodilators): Provide quick relief by relaxing airway muscles.

• Preventers (Inhaled corticosteroids): Reduce inflammation and prevent asthma attacks.

• Leukotriene Modifiers: Block chemicals involved in the allergic response.

• Biologic Therapies: Target specific pathways in the immune system for severe cases.

Allergy Shots (Immunotherapy)

Involves regular injections of allergens to desensitise the immune system over time. This treatment is typically considered when other management strategies are ineffective.

The Link Between Asthma and Allergies

Understanding the Connection

Allergic reactions can lead to inflammation in the airways, increasing the risk of asthma symptoms. Managing allergies effectively can help control asthma and improve overall respiratory health.

Managing Both Conditions

• Follow an asthma action plan

• Use medications as prescribed

• Avoid known allergens

• Regularly monitor asthma symptoms

Thunderstorm Asthma

This type of asthma occurs when certain weather conditions, such as high pollen levels and specific wind patterns, lead to an increase in asthma attacks. Individuals with asthma should take precautions during high pollen seasons and stay informed about weather conditions.

What to do during an allergic asthma attack?

• Use your reliever medication immediately

• Follow your asthma action plan

• Seek emergency medical help if symptoms persist

Creating a Comprehensive Asthma Management Plan

Working with Healthcare Providers

Collaborate with your doctor to develop a personalised asthma action plan. Regular check-ups and open communication are essential for effective management.

Incorporating Allergy Test Results

Integrate the findings from allergy tests into your management plan to avoid triggers and adjust treatments accordingly.
