• Asthma is a long-term lung condition that is caused when your airways narrow.
• Common symptoms of asthma include wheezing, coughing, feeling 'out of breath' and tightness in your chest.
• Symptoms are usually mild, but they can flare up — this can cause an 'asthma attack' and you may need hospital care.
• Asthma symptoms and asthma attacks can be managed and prevented with different medicines.
