Asthma, also known as allergic bronchitis by some doctors, is a lung disease that causes narrowing of the airways, leading to difficulty breathing. It usually begins in childhood, especially before the age of 5.

  • Cold or bronchitis
  • Dust, mold, and animal dander
  • Cigarettes or perfume in the environment
  • Exercise, especially in cold or dry air
  • Fear, anger, or excitement

What Are the Signs & Symptoms of Asthma?

  • Wheezing (high-pitched sound when exhaling)
  • Tightness in the chest
  • Coughing, especially in cold air or during exercise (sometimes coughing is the only symptom)
  • Shortness of breath

When Should You Go to the Hospital?

If your child has any of the following symptoms, go to the emergency room immediately:

  • Difficulty breathing, which may include loud wheezing, shortness of breath, or gasping
  • Sweating, pale complexion
  • Decreased blood oxygen saturation, leading to bluish lips or fingers
