It is not normal for a woman to experience significant abdominal pain and lumbago in the early stages of pregnancy. The more common cause is pre-eclampsia, and if the digestive system problems are caused by dietary inattention, significant abdominal pain or lumbago may easily occur. If there is obvious abdominal pain or lumbago in early pregnancy, the possibility of pre-eclampsia should be ruled out. It is also necessary to examine the uterus through ultrasound to find out whether there is obvious bleeding in the uterus and to check whether the development of the gestational sac conforms to the gestational week. If the levels are abnormally low, progesterone or dydrogesterone supplementation should be used to preserve the pregnancy. If there is no obvious manifestation of pre-eclampsia after the relevant examination, the problem is caused by the digestive system, which can be improved by appropriate dietary adjustment.
