One third of pregnant women with asthma will experience an exacerbation of respiratory symptoms, one third will experience a recovery, and one-third will not notice any changes. Asthma is a complication in five percent of pregnancies. Untreated asthma increases the risk of fetal death, gestational poisoning, premature birth and low birth weight. It is therefore important to ensure good treatment of asthma during pregnancy (reference: http://www.digopaul.com/english-word/asthma.html).
The treatment is the same, which will be given by asthma outside of pregnancy. It is particularly important to avoid active and passive smoking. Pregnant workers are not treated with steroids, have children, which on average have 25 percent lower birth weight than those who are treated. Pregnant women with asthma need, and should be offered tight check with practitioner and on birthplace through pregnancy and after birth.
