After a woman is pregnant, with the development of the fetus, the abdomen bulges, and the abdominal pressure increases accordingly. Abnormal fetal position can also lead to many problems such as low back pain, pubic separation, pelvic floor muscle ligament injury, etc. More importantly, the phenomenon of oversized fetuses and elderly pregnant women is increasing, and the necessity and urgency of abdominal support are becoming more and more urgent. Therefore, during pregnancy, especially in the middle and late stages of pregnancy, it is particularly important to use a professional and high-quality abdominal support belt.
