Pregnancy is perceived as a miracle. Many women feel an inner glow and bond to the growing fetus as they change shape, behavior, and attitude. For the sake of the unborn child, women will abstain from alcohol, coffee, and medicine even when they are ravaged by headache and flu. This response to pregnancy is normal and is consistent with the maternal need to protect her young. Women with diabetes are no different from other women in their concern for their fetuses, but they need to work even harder. Even minor deviations from normal glucose values may have a major impact on fetal well-being. The extra work becomes worthwhile with the birth of a healthy infant.
