Diarrhea and stomach rumbling in late pregnancy will not affect the baby if the condition is not serious, but if the diarrhea is serious in late pregnancy, it will show an increase in the number of stools and severe stomach pain, which may lead to uterine contractions during the process of stomach pain and cause premature labor, or the diarrhea is particularly serious and will show dehydration. The process of dehydration can lead to fetal ischemia and lack of oxygen in the uterine cavity, resulting in malnutrition and affecting the growth and development of the fetus. If the diarrhea is not particularly serious, it will not affect the baby very much. We should adjust our diet and improve our living habits, pay attention to keeping warm, eat a light diet and use astringent medicine to relieve the symptoms.
