About Asthma

Asthma makes the airways swell and tighten. This can make it hard to breathe.

Allergies can make asthma worse. During an asthma attack, breathing can be very hard. In a severe attack, the airways can close, which is an emergency.

Taking asthma medicine can help prevent attacks and make symptoms better

What happens during an asthma attack?

  • The lining inside the airways gets swollen
  • Thick mucus fills the airways
  • Air cannot move in and out easily
