What change should be expected in blood pressure during pregnancy when engaging in exercise?

During pregnancy, the body undergoes various physiological changes that can affect blood pressure. Engaging in regular exercise during this time is generally beneficial and can lead to adaptations in cardiovascular function. While some women may experience slight fluctuations in blood pressure due to hormonal changes and increased blood volume, moderate exercise is associated with a stabilizing effect on blood pressure.

Research indicates that regular physical activity can help maintain blood pressure within a healthy range throughout pregnancy. Typically, women may experience a decrease in blood pressure in the first and second trimesters due to vasodilation and changes in vascular resistance. However, as pregnancy progresses, blood pressure often returns closer to pre-pregnancy levels. Exercise can further help in this regulation process, leading to little to no significant change overall when measured during physical activity.

Choosing a response suggesting no change in blood pressure reflects the understanding that the body adapts to exercise in a way that stabilizes blood pressure levels, promoting cardiovascular health both for the pregnant individual and the developing fetus.
