The symptoms of asthma can range from mild to severe. When asthma symptoms get significantly worse, it is known as an asthma attack.
The symptoms of asthma include:
• feeling breathless (you may gasp for breath)
• a tight chest, like a band tightening around it
• wheezing, which makes a whistling sound when you breathe
• coughing, particularly at night and early morning
• attacks triggered by exercise, exposure to allergens and other triggers
You may experience one or more of these symptoms. Symptoms that are worse during the night or with exercise can mean your asthma is getting worse or is poorly controlled. Talk to your doctor or asthma nurse about this.
