Management of asthma in pregnancy.
1. Approximately a third of mothers find their asthma improves during pregnancy, while one third stay the same and the remainder's asthma worsens. 2. Asthma needs to be controlled; if it is not, the fetus may receive insufficient oxygen. 3. The two main types of asthma arise from different causes and have different patterns of inheritance, although in many cases the originating stimulus is the same. 4. A polluted environment contributes to the production of allergens and irritants which trigger asthma in susceptible people.
