Pregnant women with herniated lumbar discs should control their diet during pregnancy to avoid excessive weight gain during pregnancy, and need to avoid sedentary and bending during pregnancy. The lumbar spine will definitely be affected by the gradual enlargement of the uterus after pregnancy, so it is very important to control the weight, and the larger the fetus is, the greater the pressure on the lumbar spine may be. Normally, pregnant women should try to avoid bending over, avoid lying down for a long time and sitting for a long time, and straighten their backs whether they are standing or sitting, so as to avoid the lumbar intervertebral discs from being further compressed and causing pain aggravation. It is recommended that pregnant women go to the hospital regularly for maternity checkups, and once symptoms of discomfort occur during pregnancy, they should consult a doctor in a timely manner.
