Symptoms of sciatic nerve compression can occur after pregnancy, although they tend to occur after the middle and late stages of pregnancy. As the number of months of pregnancy increases, the chances of sciatic nerve compression symptoms increase accordingly. The main reason for this is that the uterus grows significantly larger with each month of pregnancy, and the protruding abdomen increases the pressure on the spine, leading to sciatic nerve compression. Prolonged physical inactivity, sedentary lifestyle, and calcium deficiency in pregnant women can cause or aggravate the manifestations of sciatic nerve compression. In order to prevent sciatic nerve compression during pregnancy, pregnant women should pay attention to proper body movement after pregnancy, not to stay in the same position for a long time, and should pay attention to proper calcium supplementation.
