Chiropractic care is the health maintenance of the spinal column, discs, related nerves, and bone geometry without drugs or surgery. It involves the art and science of adjusting misaligned joints of the body, especially of the spine, to promote health throughout the body. Chiropractic care is safe during pregnancy when provided by a chiropractor that has been trained in the physical changes that occur within a pregnant woman's body. Chiropractors that have been trained to work with pregnant women will use tables that adjust for a pregnant woman's body and they will use techniques that avoid unneeded pressure on the abdomen.
