All About Asthma: Triggers, Treatment, and Prevention

As an asthma sufferer, you know how frightening and debilitating an asthma attack can be. Your airways tighten and swell, making it difficult to breathe. Asthma is a chronic respiratory disease that affects over 25 million Americans, including 5 million children. The good news is with proper treatment and management, most asthma symptoms can be controlled.

In this article, you will learn about the common triggers that can spark asthma flare-ups and exacerbate your symptoms. You will discover the various medications available to open your airways and reduce inflammation. You will also find helpful tips and strategies to better manage your asthma and avoid emergency room visits. Though there is no cure for asthma, gaining a better understanding of your condition and treatment options can help you breathe easier and live an active, healthy life despite this chronic disease.

Asthma Triggers: What Can Trigger an Asthma Attack?

Asthma triggers are environmental factors that can cause inflammation in the airways and lead to asthma symptoms like coughing, wheezing, and shortness of breath. Being aware of and avoiding triggers can help prevent asthma attacks and keep symptoms under control.

Common asthma triggers include:

  1. Airborne allergens: Pollen, dust mites, mold, and pet dander are common allergens that can trigger asthma symptoms in susceptible individuals.
  2. Irritants in the air: Pollution, smoke, aerosol sprays, and harsh fumes or odors may irritate airways and trigger asthma.
  3. Respiratory infections: Colds, the flu, and bronchitis can inflame airways and worsen asthma symptoms. Practice good hygiene like hand washing to avoid getting infections.
  4. Weather changes: Extreme cold or hot weather, especially changes in barometric pressure, may trigger asthma in some people.
  5. Occupational exposures: Chemicals, fumes, or dust in the workplace can trigger “occupational asthma” in exposed individuals. Seek medical advice about potential work-related triggers.
  6. Emotions: Strong emotions like stress, anxiety, crying or laughing hard can trigger asthma symptoms in certain individuals. Practice relaxation and coping strategies to minimize emotional triggers.

By identifying personal triggers and making an effort to avoid or minimize exposure to them when possible, individuals with asthma can gain more control over their symptoms and disease. An asthma action plan created with a doctor can also help outline the best ways to avoid and manage triggers to prevent asthma attacks. With vigilance and proper treatment, asthma triggers do not have to prevent living a normal, active life.

Asthma Treatment Options: Relieving Symptoms and Preventing Attacks

To relieve asthma symptoms and prevent attacks, several treatment options are available. Medications are typically delivered through inhalers, nebulizers, or pills.

Inhaled corticosteroids are commonly used to reduce airway inflammation. These are often paired with long-acting beta agonists (LABAs) which open airways. For quick relief during an attack, short-acting beta agonists (SABAs) can provide fast-acting bronchodilation. Leukotriene modifiers are also options to decrease inflammation.

For severe, persistent asthma, biologic therapies may be options. Omalizumab can be used for allergic asthma, and newer biologics directly target specific inflammatory pathways.

Oral medications are sometimes used, especially for children. Montelukast and zafirlukast are leukotriene receptor antagonists in pill form. Theophylline, a bronchodilator, also comes as a pill but can have side effects.

Frequent medical checkups, especially when starting or changing medications, are important. Lung function tests and other monitoring help determine if treatments are working or need adjustment. An asthma action plan should be developed with your doctor to manage symptoms and know when to seek emergency care.

Avoiding triggers like allergens, irritants, pollutants and respiratory infections can significantly help reduce asthma flare-ups and the need for medications or hospital visits. Making lifestyle changes and learning proper disease management techniques are key to controlling asthma in the long run.

With the right treatment and prevention strategies, most people with asthma can avoid severe attacks and live active, healthy lives. By working closely with your doctor, you can find an effective treatment plan tailored to your needs.

How to Prevent Asthma Attacks: Creating an Asthma Action Plan

To prevent asthma attacks, it is critical to identify and avoid triggers that irritate your airways. Work with your doctor to create an asthma action plan tailored to your specific triggers and symptoms. This plan should include:

Environmental Control

Make your home environment asthma-friendly by reducing exposure to allergens and irritants like dust mites, pet dander, mold, and harsh chemicals. Encase mattresses and pillows in allergen-proof covers, vacuum frequently with a HEPA filter, and consider rehoming pets if needed.

Medication Adherence

Take all prescribed controller and rescue medications as directed by your doctor. Controller medications like inhaled corticosteroids help reduce airway inflammation to prevent attacks. Rescue inhalers quickly relieve symptoms when an attack occurs. Use a spacer with inhalers for maximum effectiveness and ask your doctor about nebulizer treatments if inhalers are not working well.

Monitoring and Record-Keeping

Keep an asthma diary to record symptoms, triggers, and medications taken. Note the time, severity, and duration of attacks to help determine patterns. Share this information with your doctor to make adjustments to your treatment plan. They may order lung function tests to monitor the severity and determine if symptoms are well-controlled.

Avoiding Triggers

In addition to controlling environmental allergens, avoid other common triggers like respiratory infections, cold air, smoke, pollution, and strenuous exercise. Wash hands frequently, dress warmly in cold weather, and use a scarf to cover your mouth. Stay indoors on high air pollution days and avoid smoky areas. Warm up before exercise and use an inhaler as prescribed to prevent exercise-induced attacks.

Following an asthma action plan tailored to your needs can help get symptoms under control and prevent life-threatening attacks. Be diligent in avoiding triggers, taking medications as prescribed, and monitoring your condition. See your doctor right away if your symptoms are not improving or you are using your rescue inhaler more than twice a week. With proper management, asthma does not have to limit your activities and quality of life.


With vigilance and proper treatment, asthma can be managed well. You have learned about common asthma triggers and how to avoid them. You now understand the various medications available to open airways and reduce inflammation, allowing you to live symptom-free. Make sure to work closely with your doctor to develop an effective asthma action plan tailored to your needs.

Though asthma cannot be cured, it can be controlled. By identifying your personal triggers, properly using medications as prescribed, and making healthy lifestyle changes, you can prevent asthma attacks and live life fully. You have the power to take an active role in your asthma management and improve your quality of life. Though the responsibility ultimately lies with you, with the support of your medical team and loved ones, you can gain confidence in keeping your asthma in check and doing all the things that matter most to you.
