Understanding Asthma: A Guide to Managing Your Breathing

. The description of asthma medication reflected superseded guidance under which a bronchodilator-only rescue inhaler was acceptable for people with infrequent symptoms. Current international guidance is that anti-inflammatory treatment with an inhaled corticosteroid — taken daily, or in a combination inhaler used as needed — should be part of treatment for essentially everyone with asthma, because reliever-only treatment leaves airway inflammation untreated and carries a higher risk of severe flare-ups. The medication passage has been corrected; nothing else in the article was changed.

Asthma is a chronic condition in which the airways become inflamed, narrowed, and produce excess mucus in response to certain triggers, causing wheezing, coughing, chest tightness, and shortness of breath. It affects people of all ages and can range from mild and occasional to severe and frequent.

While asthma cannot be cured, it can be very effectively controlled with the right combination of medication, trigger avoidance, and a clear action plan. Most people with well-managed asthma are able to exercise, sleep, and go about daily life without significant limitation.

Understanding Asthma Triggers

Common asthma triggers include allergens (pollen, dust mites, pet dander, mold), respiratory infections, cold air, exercise, tobacco smoke, strong odors, and air pollution. In the Central Valley specifically, seasonal air quality changes, agricultural dust, and wildfire smoke can be significant triggers for many patients.

Identifying your personal triggers is an important part of asthma management, since avoiding or reducing exposure to them can meaningfully reduce how often you need rescue medication and how well-controlled your asthma feels day to day.

Types of Asthma Medication

Inhaled corticosteroids reduce airway inflammation over time and are the foundation of asthma treatment. Current international guidance is that essentially everyone with asthma should be taking an inhaled corticosteroid in some form — either daily as a controller, or combined with a fast-acting bronchodilator in a single inhaler used as needed — rather than relying on a bronchodilator-only rescue inhaler, even when symptoms are infrequent. Treating with a rescue inhaler alone leaves the underlying inflammation untreated and is associated with a higher risk of severe flare-ups. These need to be taken consistently, even when you feel well, to keep inflammation — and future flare-ups — under control.

Rescue medications, typically short-acting bronchodilators like albuterol, work within minutes to relax airway muscles during a flare-up or before exercise, but they do not treat the underlying inflammation. Needing your rescue inhaler more than twice a week (outside of exercise use) generally signals that your controller regimen needs adjustment.

Creating an Asthma Action Plan

A written asthma action plan, developed with your doctor, uses your symptoms or a simple breathing measurement device (peak flow meter) to divide your asthma into green, yellow, and red zones, each with specific instructions for medication and when to seek care. This turns confusing in-the-moment decisions into clear, pre-planned steps.

Action plans are especially valuable for recognizing early warning signs of a worsening flare-up before it becomes severe, and for knowing exactly when symptoms have crossed into an emergency requiring immediate care rather than more rescue inhaler use at home.

Living Well with Asthma

Regular follow-up with your doctor, even when asthma feels well controlled, allows for adjustment of medication as needed and reinforcement of proper inhaler technique, which is a surprisingly common source of poor control when done incorrectly. Annual flu vaccination and staying current on other recommended vaccines helps prevent respiratory infections that commonly trigger flare-ups.

With consistent treatment, most people with asthma can participate fully in exercise and sports — in fact, regular physical activity is encouraged and, for many, using a rescue inhaler before exercise prevents exercise-induced symptoms entirely.

Signs Your Asthma May Need Better Control

• Using your rescue inhaler more than twice a week (not counting before exercise)
• Waking at night due to asthma symptoms
• Symptoms limiting your normal activities or exercise
• Needing oral steroids for a flare-up more than once a year
• Unsure of your correct inhaler technique
• No written asthma action plan in place
• Recent increase in symptom frequency or severity

When to Contact a Clinician

Contact your doctor if you are using your rescue inhaler more than twice weekly, waking at night with symptoms, or noticing your asthma control declining. If you do not have a written asthma action plan, ask your doctor to create one with you at your next visit.

Questions to Ask at a Medical Visit

• Can we create or update my written asthma action plan?
• Am I using my inhaler with correct technique?
• Should my controller medication be adjusted based on my symptom frequency?
• What are my specific asthma triggers, and how can I reduce exposure?
• Is it safe for me to exercise, and how should I prepare?
• What vaccines are especially important given my asthma?

Main Takeaway

Asthma is a manageable chronic condition, and most people achieve excellent control with the right combination of controller medication, trigger avoidance, and a clear action plan. Needing rescue medication frequently is a sign that treatment needs adjustment, not something to simply tolerate.
