Asthma is a widespread condition that affects the lung, making it difficult to breathe. People of all ages have asthma, and it usually begins in early childhood. It can in some circumstances appear later in life. There is no cure for asthma, but there are many ways it can be treated. Through the use of inhalers, sufferers can keep their asthma under control. Some children also grow out of their asthma, but for many it people it remains a lifelong affliction. Those who have asthma will usually experience breathlessness, a tight chest, coughing, as well as wheezing. Severe asthma can even cause a whistling sound when breathing. The severity of the symptoms varies from every person, and when it becomes difficult to breathe, this is known as an "asthma attack." Some known triggers for asthma attacks include exercise, infections, strong smells, and allergens. The scientific community does not yet fully understand why some people develop this condition.
