Many, many women who are pregnant find themselves short of breath at some point. One reason is that the uterus is expanding and pushing up into the abdomen. This squeezes the lungs a bit, reducing the space they have for oxygen exchange. An even bigger cause for shortness of breath is progesterone, a hormone that increases during pregnancy. High progesterone levels cause pregnant women to breathe faster. The rise in progesterone begins early in pregnancy, and the shortness of breath it causes can come as a surprise. While shortness of breath can be worrisome, most of the time it is harmless and due to the normal changes of pregnancy.
