Asthma and allergic rhinitis are two of the most common health
problems worldwide and can present serious complication during
pregnancy. While these diseases may improve, remain unchanged, or
become exacerbated during pregnancy, they are frequently under-
diagnosed and under-treated. The inflammatory processes involved in
asthma and allergic rhinitis are superimposed on the normal respiratory
changes of pregnancy, making early intervention crucial. Recognition
of factors that can aggravate asthma, implementation and adherence to
treatment guidelines, and diligent follow-up are important in midwifery
management. Patient education is particularly important for prevention
of asthma exacerbations. With careful control of asthma and allergic
rhinitis, if present, excellent obstetrical outcomes can be expected.
