The risk of falling is increased for pregnant women with:

During pregnancy, a woman's body undergoes significant physiological changes, one of which is a shift in the center of gravity. This change occurs as the baby grows and the uterus expands, causing the weight to distribute differently and alter the balance of the body. The forward shift in the center of gravity can lead to instability, making it more challenging for pregnant women to maintain their balance.

As a result, this shift is a direct contributor to an increased risk of falling. Maintaining balance becomes more complex, particularly during movements that require agility or quick adjustments. Awareness of this change is important for expecting mothers, as it underscores the need for careful movement and attention to their body's new mechanics during daily activities as well as any exercise routines.

Other factors, such as decreased coordination, lack of exercise, and poor nutrition, while they can contribute to overall physical fitness and wellbeing, do not directly cause the same level of change in balance due to the structural and physical adjustments a pregnant body experiences.
