Asthma 101: What Triggers an Asthma Attack?


Asthma, a chronic respiratory condition affecting millions of people worldwide, is often characterized by episodes of breathlessness, wheezing, and coughing, known as asthma attacks. At TexasAllergyMD, with locations in McKinney/Prosper and Southlake, Texas, we believe that a key component of effectively managing asthma is understanding what can trigger these attacks. Let’s delve into the factors that can set off an asthma flare-up.

Deciphering Asthma and Its Triggers

Asthma is a condition in which your airways narrow and swell, producing extra mucus. This can make breathing difficult and trigger coughing, wheezing, and shortness of breath. Asthma attacks can vary from mild to severe and, in some cases, can even be life-threatening.

It’s crucial to understand that the triggers of asthma attacks differ from person to person. What may cause an asthma attack in one person may not affect another. Asthma presentation also differs from child vs. adult. Let’s explore some of the most common asthma triggers:

1. Allergens:

Allergens are substances that cause allergic reactions and can trigger asthma attacks. These include:

  • Pollen from trees, grasses, and weeds
  • Dust mites
  • Pet dander from cats and dogs
  • Mold spores
  • Cockroach droppings

2. Irritants:

These are substances that can irritate the airways and trigger an asthma attack:

  • Tobacco smoke
  • Chemical fumes and vapors
  • Air pollution
  • Strong odors from paints or cleaning products
  • Dust or particles in the air

3. Health Conditions:

Certain health conditions can provoke asthma symptoms:

  • Respiratory infections, such as the common cold or flu
  • Sinusitis
  • Gastroesophageal reflux disease (GERD)

4. Physical Factors:

Certain physical factors can also instigate an asthma attack:

  • Exercise, particularly in cold, dry air
  • Changes in the weather, such as cold air or extremely dry, wet, or windy weather
  • Strong emotions, such as stress, anxiety, or laughter

Navigating Asthma Triggers

Once you know what triggers your asthma, you can take steps to avoid these triggers and reduce the likelihood of an asthma attack. Here are a few strategies:

For Allergens:

  • Regularly clean your home to reduce dust mites
  • Keep pets out of your bedroom
  • Purchase Dust mite covers for your pillows, boxsprings and mattresses
  • Use air conditioners when pollen counts are high
  • Repair leaks to prevent mold
  • Start Sublingual Immunotherapy (Allergy drops) to aggressively manage your allergy triggers

For Irritants:

  • Avoid smoking and secondhand smoke
  • Use natural cleaning products
  • Stay indoors on high air pollution days

For Health Conditions:

  • Get regular check-ups to manage other health conditions
  • Get vaccinated for flu and pneumonia
  • Manage GERD symptoms with the help of a healthcare provider

For Physical Factors:

  • Warm up before exercising and cool down afterward
  • Dress appropriately for the weather
  • Practice stress management techniques
