During pregnancy, the growth of the fetus may result in the expansion of the uterus. As a result, the expecting mother will experience increased burden on her waist and back due to the shift of her body’s gravity. This will in turn lead to fatigue and back pain for women during pregnancy. This is why pregnant women should maintain appropriate posture at all times and refrain from prolonged sitting or standing. Be sure to have ample rests and wear shoes with low heels or flat soles. It also helps to engage in exercises during pregnancy under the guidance of a medical attendant.
