Asthma is a common lung condition that causes occasional breathing difficulties.
It affects people of all ages and often starts in childhood, although it can also develop for the first time in adults. There's currently no cure, but there are simple treatments that can help keep the symptoms under control so it does not have a big impact on your life.
Causes of Asthma
Asthma is caused by swelling (inflammation) of the breathing tubes that carry air in and out of the lungs. This makes the tubes highly sensitive, so they temporarily narrow. It may occur randomly or after exposure to a trigger. Common asthma triggers include: Allergies (to house dust mites, animal fur or pollen, for example). Smoke, pollution and cold air. Exercise. Infections like colds or flu.
Treatment for Asthma
Identifying and avoiding your asthma triggers can help you keep your symptoms under control. Asthma is usually treated by using an inhaler, a small device that lets you breathe in medicines. The main types are: Reliever inhalers – used when needed to quickly relieve asthma symptoms for a short time. Preventer inhalers – used every day to prevent asthma symptoms occurring. Some people also need to take tablets.
