The analysis of female flatulence during pregnancy is as follows: a. During pregnancy, the enhanced function of the endocrine system in the body causes significant changes in the hormone content of the body, such as the rise in the content of estrogen, follicle-stimulating hormone, progesterone, luteinizing hormone and other hormones in the body, which interferes with the function of the gastrointestinal tract and can lead to flatulence in women. Second, during pregnancy, the implantation of fertilized eggs into the uterus can cause certain interference with the digestive system, which can also lead to flatulence in women. Third, during pregnancy, the digestive function may decline or even become disturbed, which can lead to indigestion and constipation, which can also lead to flatulence in women.
