Pendulous abdomen is one of the abdominal shapes of pregnant women, which is mainly manifested by the fact that the waist is not swollen from the back and is even thinner than when there is no pregnancy; however, when viewed from the front, the pregnant woman’s belly is large and her abdomen sags, called pendulous abdomen. In general, the formation of a hanging belly is related to an oversized fetus, and too much amniotic fluid. If the fetus is 7.5 pounds or more, the pregnant woman is likely to have a hanging belly. In addition, the pregnant woman’s abdominal wall muscles are too relaxed, is also a cause of the occurrence of hanging belly. It is recommended that pregnant women should exercise their abdomen during preconception to increase its muscle strength and control their diet to avoid the occurrence of a hanging belly. Once the overhanging belly is formed, it will make the pregnant woman’s center of gravity shift forward as a whole, thus affecting daily activities, and will also lead to excessive spinal burden, low back pain, separation of the pubic symphysis and other compression symptoms, so it needs to be taken seriously.
