What is Asthma?

Asthma is a chronic respiratory condition that causes inflammation and narrowing of the airways, leading to breathing difficulties, wheezing, and shortness of breath. It can vary in severity and may be triggered by allergens, exercise, cold air, or stress.

Classify Asthma

Asthma is classified as a chronic respiratory condition, often categorized as a long-term illness that affects the airways in the lungs.

Types of Asthma

• Allergic Asthma: Triggered by allergens such as pollen, dust mites, or pet dander.
• Non-Allergic Asthma: Triggered by factors like stress, exercise, or cold air.
• Exercise-Induced Asthma (EIA): Symptoms occur mainly during or after physical activity.
• Occupational Asthma: Triggered by workplace irritants like chemicals, dust, or gases.
• Nocturnal Asthma: Symptoms worsen during the night, often disrupting sleep.

Asthma Health Signs and Symptoms

• Shortness of breath
• Wheezing (a whistling sound when breathing)
• Chest tightness
• Coughing, especially at night or early morning
• Difficulty breathing after physical activity

Asthma Causes

• Genetic predisposition
• Environmental factors (pollen, smoke, pollution)
• Respiratory infections
• Allergens such as dust mites, mold, pet dander
• Occupational exposures (chemicals, fumes)

Asthma Stages

1. Mild Intermittent: Symptoms occur less than twice a week.
2. Mild Persistent: Symptoms occur more than twice a week but not daily.
3. Moderate Persistent: Symptoms occur daily and may affect daily activities.
4. Severe Persistent: Symptoms are continuous, severely limiting daily activities.

How to Prevent Asthma

• Avoid known allergens and triggers.
• Use air purifiers and keep your living space free from dust and mold.
• Get vaccinated against flu and pneumonia.
• Maintain a healthy weight to reduce strain on the lungs.
• Use prescribed medications, including preventive inhalers.

Asthma Diagnosis

Doctors typically diagnose asthma based on medical history, a physical exam, and tests such as:

• Spirometry: Measures lung function by assessing how much air you can exhale.
• Peak Flow Meter: Tests how quickly you can expel air from your lungs.
• Allergy Testing: Identifies any allergens triggering asthma symptoms.
• Methacholine Challenge Test: Determines airway sensitivity.

How to Test for Asthma

• Spirometry and lung function tests
• Allergy testing
• Chest X-rays or CT scans (to rule out other conditions)
• Nitric oxide tests (measures airway inflammation)

What Type of Health Professionals Treat Asthma?

• Pulmonologists: Specialize in lung diseases and respiratory issues.
• Allergists/Immunologists: Focus on asthma triggered by allergens.
• General Practitioners: Manage mild to moderate asthma.
• Respiratory Therapists: Help patients with breathing techniques and device use.
• Pediatricians: Treat asthma in children.

Reasons to See an Asthma Health Professional

• Frequent or worsening symptoms
• Symptoms interfering with daily life or sleep
• Medication adjustments
• Concerns about managing asthma during pregnancy or illness

Process to Find the Right Asthma Specialist

• Seek referrals from your primary doctor.
• Search for specialists with experience in respiratory or allergy care.
• Ensure they are certified in pulmonary or allergy and immunology.
• Check reviews and consider proximity to your home for regular follow-ups.

How to Prepare to See a Health Specialist?

• Bring a detailed history of symptoms and triggers.
• List current medications and treatments.
• Prepare questions regarding your asthma management.
• Track your peak flow meter readings (if applicable).

What Questions to Ask a Doctor?

• What type of asthma do I have?
• What are the best treatment options for my symptoms?
• How can I avoid my asthma triggers?
• What should I do during an asthma attack?
• Are there long-term effects of asthma on my health?

What Type of Treatments Exist?

• Rescue Inhalers (Short-acting Beta-agonists): For immediate relief during asthma attacks.
• Preventive Inhalers (Corticosteroids): Reduce airway inflammation.
• Leukotriene Modifiers: Oral medications to reduce inflammation.
• Biologic Therapies: For severe asthma (e.g., omalizumab, mepolizumab).
• Immunotherapy (Allergy Shots): For allergen-triggered asthma.

Asthma Clinical Trials

Some clinical trials are investigating new treatments, biologics, or immunotherapy for asthma. To find current clinical trials, visit resources like clinicaltrials.gov or consult your healthcare provider for local trials.

How to Monitor Asthma

• Peak Flow Meter: Monitors lung function and helps detect early signs of a flare-up.
• Smartphone Apps: Track symptoms and medication usage.
• Spirometer: Monitors lung function and severity of asthma over time.

How to Manage Asthma – Living with Asthma Recommendations

• Use a daily preventive inhaler if prescribed.
• Monitor lung function regularly.
• Avoid known allergens and triggers.
• Stay active but adjust exercise intensity based on your symptoms.

How to Care for Someone with Asthma

• Help manage medications and keep track of inhaler use.
• Know the signs of a severe asthma attack and when to seek emergency help.
• Keep the environment clean and allergen-free.
• Ensure they have quick access to rescue inhalers during flare-ups.

Nutrition Dos and Don’ts

Dos:

• Eat anti-inflammatory foods like fruits, vegetables, and omega-3 rich fish.
• Stay hydrated.

Don’ts:

• Avoid processed foods high in trans fats and preservatives.
• Minimize salt intake, which can worsen inflammation.

Lifestyle Dos and Don’ts

Dos:

• Stay active with controlled and moderate exercises.
