Lifting too much weight would not hurt the baby that is safely situated in the uterus. It cannot damage the placenta either. The possible problems from lifting weight in pregnancy might be experienced by the mother.


During pregnancy the connective tissue (ligaments) that keep the joints firm, tend to be more elastic in order to prepare the pelvis for the delivery. So, if you lift heavy weight your spine joints might suffer enough for temporary or permanent damage to be done. There is no actual consensus in medical professionals about how much weigh is too much to be lifted in pregnancy. It depends on many factors, but generally less is better.


You might want to talk with your gynecologist whether the heavy lifting might affect your health. Your previous spine condition would be taken into account in order to avoid any damage to your back.
