In early pregnancy, there is always the feeling of wanting to defecate caused by several reasons: 1. It is a normal physiological phenomenon, because in the early stages of pregnancy, the fertilized egg in the uterus of a woman has just started its initial development. The level of hormones in a woman’s body will change significantly, such as estrogen, sex hormones, progesterone, etc. are much higher than the content of women who are not pregnant. These hormones can also indirectly act on the female digestive system, especially the colon to produce the feeling of wanting to poop, which is caused by neurohumoral regulation. 2, may be due to mental and neurological factors, because women have certain emotional changes in the early stages of pregnancy. This can also indirectly act on the pelvic floor nerves through neurohumoral regulation, especially the muscle nerves that innervate the anus, leading to increased neural excitability, which can lead to the abnormal feeling of always wanting to defecate in the early stages of pregnancy.
