It is useful to use abdominal belts after giving birth, and its functions mainly include fixing internal organs, fixing wounds and strengthening lumbar support. 1. Fixing internal organs: After giving birth to a child, the uterus shrinks rapidly, and the use of abdominal belts can promote the organs that have been squeezed to other parts to return to their original positions, so as to achieve the purpose of fixing internal organs. 2. Fixing wounds: The use of abdominal belts can also fix abdominal wounds after giving birth. The belt will produce a certain amount of pressure to stop bleeding. 3. Strengthening lumbar support: women’s muscle ligaments function abnormally after giving birth, and the lumbar support is weaker. The use of a belly band can strengthen the lumbar support.
