"You must have wondered why pregnant women seem to tilt backward as the pregnancy progresses and the fetus increases in size. This is medically known as Lordosis. It is characterized by the inward curvature of the spine. It occurs as a result of the adjustment of the spine to realign the center of gravity."
At first I thought it was due to the heavy weight of some babies that causes this. I have really learnt a lot.
Well, you didn’t think wrong at all. The increasing weight of the baby causes the backward tilting in order to align to center of gravity. Thank you @jude9 for stopping by.
