Abdominal discomfort during pregnancy can have gastrointestinal as well as reproductive causes. If it is caused by the gastrointestinal tract, it is often accompanied by nausea, vomiting, bloating and diarrhea. It is necessary to exclude whether it is a reproductive system disease to prevent miscarriage. A preeclamptic miscarriage entails abdominal discomfort or vaginal bleeding, which is small at first and may increase at a later stage. When abdominal discomfort occurs after pregnancy, it is recommended to go to the hospital in a timely manner. During pregnancy, it is important to avoid lifting heavy objects, strenuous exercise, and sexual intercourse, especially in early and late pregnancy, and it is necessary to pay attention to dietary habits, and to avoid eating unclean food, in order to prevent the emergence of acute gastroenteritis.
