Asthma

What is it?

Asthma is a chronic respiratory condition characterised by inflammation and narrowing of the airways, leading to recurrent episodes of wheezing, breathlessness, chest tightness, and coughing. These symptoms are often triggered by exposure to allergens, irritants, respiratory infections, physical activity, or changes in weather. Asthma affects people of all ages, but symptoms may vary in severity and frequency from person to person. While there is no cure for asthma, it can be managed effectively with proper treatment and lifestyle modifications.

What can I do?

1. Follow Asthma Action Plan: Work with your healthcare provider to develop a personalized asthma action plan that outlines medications, triggers to avoid, symptom management strategies, and steps to take during asthma attacks or exacerbations. Adhere to the action plan consistently to optimize asthma control and minimise symptoms.
2. Medication Adherence: Take prescribed asthma medications as directed by your healthcare provider, including controller medications to reduce inflammation and prevent symptoms, as well as rescue medications to relieve acute symptoms during asthma attacks. Use inhalers or nebulisers correctly and regularly to ensure optimal drug delivery to the airways.
3. Identify and Avoid Triggers: Identify and minimise exposure to asthma triggers such as allergens (e.g., pollen, dust mites, pet dander), irritants (e.g., tobacco smoke, air pollution, strong odors), respiratory infections, cold air, exercise, and stress. Implement measures to reduce indoor allergens and improve indoor air quality, such as using allergen-proof bedding, regularly vacuuming carpets, and maintaining adequate ventilation.
4. Monitor Lung Function: Use a peak flow meter or spirometer to monitor lung function regularly and track changes in airflow limitation. Follow monitoring guidelines provided by your healthcare provider and seek medical attention if you notice significant declines in lung function or worsening asthma symptoms.
5. Lead a Healthy Lifestyle: Maintain a healthy lifestyle by eating a balanced diet, staying physically active, managing stress, getting enough sleep, and avoiding tobacco smoke and other respiratory irritants. Regular exercise can improve lung function, reduce inflammation, and enhance overall well-being in people with asthma.

Common Medical Treatments

1. Inhaled Corticosteroids: Inhaled corticosteroids are the most effective long-term control medications for asthma, reducing airway inflammation and preventing asthma symptoms. They are typically used as maintenance therapy in combination with other asthma medications.
2. Bronchodilators: Short-acting beta agonists (SABAs) and long-acting beta agonists (LABAs) are bronchodilator medications that help relax and open the airways, relieving acute asthma symptoms and preventing exercise-induced bronchoconstriction. They are often used as rescue medications or in combination with corticosteroids for long-term asthma control.
3. Leukotriene Modifiers: Leukotriene modifiers are oral medications that block the action of leukotrienes, inflammatory substances that contribute to asthma symptoms and airway inflammation. They are used as maintenance therapy in people with mild to moderate asthma or as adjunct therapy in combination with other asthma medications.
4. Immunotherapy: Allergy shots or sublingual immunotherapy (SLIT) may be recommended for people with allergic asthma to desensitise the immune system to specific allergens and reduce asthma symptoms triggered by allergen exposure.
5. Biologic Therapies: Biologic medications such as omalizumab, mepolizumab, reslizumab, and benralizumab target specific immune pathways involved in allergic asthma or eosinophilic asthma and are used to treat severe, uncontrolled asthma that does not respond to standard therapies.

When to Consult Your Doctor

It is important to consult your doctor if you experience:

• Persistent or worsening asthma symptoms despite adherence to asthma medications and management strategies.
• Frequent asthma exacerbations requiring rescue medication use, oral corticosteroids, or emergency medical treatment.
• Difficulty breathing, wheezing, or chest tightness that interferes with daily activities or sleep.
• Signs of a severe asthma attack, such as severe shortness of breath, rapid breathing, difficulty speaking, or bluish discoloration of the lips or fingernails.

Remember:

Asthma is a chronic condition that requires ongoing management and support. By working closely with healthcare providers, following treatment recommendations, and making lifestyle modifications, individuals with asthma can effectively control symptoms, prevent exacerbations, and maintain a high quality of life. Education, self-management skills, and support from family, friends, and healthcare professionals are essential components of asthma management.
