<p>One or more of the following things can happen to make your child's airways narrow.</p><ul><li>The lining of the airways gets thick and swells. This is called inflammation.</li><li>The muscles around the airways squeeze together and get tight. This is called bronchospasm or bronchoconstriction.</li><li>The airways make a lot of thick liquid called mucus.</li></ul><p>All of these reactions make your child's airways narrower. This makes it harder for air to pass in and out of the lungs.</p> | <h2> Key points </h2><ul><li>Asthma can be a lifelong condition, but good asthma control can allow your child to live a normal life.<br></li><li>Asthma symptoms are different in different children.</li><li>In certain conditions, a child with asthma's airways become narrower, making it harder to breathe.<br></li></ul> | | <figure class="asset-c-100">
