Asthma is not generally considered by doctors to be a serious illness in most people who have it, mainly due to the mildness of symptoms and the range of very effective medicines that control these symptoms and stop asthma worsening. Asthma does, however, have an effect on quality of life because attacks can be unpleasant and distressing and can restrict activity. Whilst most sufferers learn to live with and manage their condition, for some it can be disabling. In exceptional cases, asthma can be life-threatening, particularly if it is not treated adequately or promptly. For some of these, an attack is so severe that it results in death.
