During pregnancy, the size of the heart typically does what?

Explanation:
During pregnancy the heart size increases modestly as part of normal adaptation to the body's bigger blood volume and higher cardiac workload. Blood volume rises by roughly 40–50%, heart rate often increases, and stroke volume rises too, so cardiac output goes up significantly. The heart adapts with slight enlargement and chamber dilation to handle the greater preload. This change is typically within normal limits and usually reverses after delivery. If enlargement were pronounced or accompanied by symptoms, it could suggest a problem, but in a healthy pregnancy it’s a typical, temporary adjustment.
