The fluid in the uterine cavity that appears during pregnancy is mostly caused by bleeding from the gestational sac, which is a manifestation of pre-eclampsia and generally indicates embryonic dysplasia or insufficient progesterone level. At this time, food does not have an obvious effect on promoting the absorption of the fluid in the uterine cavity, and the most important thing is to identify the specific cause of bleeding from the gestational sac and assess whether the development of the gestational sac is normal and whether it has the value of fetal preservation. If the size of the gestational sac is consistent with the gestational week after examination, and if it is determined to have the value of fetal preservation treatment, it is necessary to supplement progesterone for fetal preservation treatment, and hemostatic drugs are not effective. The diet can include various kinds of soy products, durian and honey, which have the effect of balancing the hormone level in the body.
