Asthma is a disease of the lungs. When you have asthma, the airways are very sensitive to many things in the air. The airways may get smaller when you are around things that trigger your asthma. This is called a flare-up.
What happens during an asthma flare-up?Asthma can be very serious. Breathing problems that start out mild can turn deadly. Three main things happen during an asthma flare-up that can make it hard to breathe:
- The airways swell and they become smaller.
- The airways fill with mucus.
- The muscles around the airway tighten and squeeze the airways making them smaller.
Asthma flare-ups begin with swelling in the airways. Asthma flare-ups or serious attacks can happen if the swelling is not treated. Taking medicines to control the swelling can prevent an asthma flare-up. Medicines that treat the swelling must be used every day. Follow the Asthma Action Plan that your doctor gives you.
Can asthma be cured?The good news is that asthma can be controlled. There is no medicine that can cure asthma. Asthma symptoms often improve as children get older. However, this may take a long time.
Warning signsMost asthma flare-ups start slowly. You may notice small changes in your child’s body before a flare-up. Changes include:
- runny or stuffy nose
- itchy or watery eyes
- itchy or sore throat
Many things can cause an asthma flare-up. They are called triggers. Know your child’s asthma triggers and avoid them.
