During pregnancy, the demands on a woman's body increase substantially. While pregnancy affects every woman differently, the following guidelines are suggested in the selection of appropriate activity levels. The question of whether to work, and for how long is up to the woman and her doctor.
Some women can work up until just before the birth of the baby, even in high stress, demanding jobs.
As long as the pregnancy is healthy, and the mother's health is good, working poses no risk to either her or the baby. Working in a job that is physically demanding or that requires exposure to toxic metals, chemicals or x-rays can result in abnormal fetal development, miscarriage or birth defects. The decision to continue in such a job should be made carefully, with the help of a doctor. A temporary leave of absence or transfer to another department may be advised. A working, pregnant woman should take occasional breaks, change positions often, and rest whenever possible, especially as pregnancy progresses.
