Constipation is very common in pregnant women, and if long-term constipation has an impact on the fetus, it should be corrected in a timely manner and regular pregnancy checkups should be conducted so as to benefit the health of the pregnant woman and the fetus. Pregnant women in the early stages of pregnancy who are at risk of pre-eclampsia are not advised to force a bowel movement when constipated. Although in general, straining during defecation does not pose a risk of miscarriage, attention should be paid if there is vaginal bleeding with back pain and other symptoms of pre-eclampsia, as straining during defecation may increase the possibility of vaginal bleeding. Secondly, a pregnant woman with constipation will eat less because of poor bowel movement, which may reduce the appetite of the lighter ones and worsen the intestinal dysfunction over a long period of time. If constipation has occurred, do not use laxatives indiscriminately, otherwise it will cause miscarriage and premature birth. If you are always constipated and do not have a bowel movement, it will also affect the absorption of nutrients, which will certainly affect the development of the fetus. Therefore, constipation is sometimes unavoidable in pregnant women. As the uterus increases in size in late pregnancy, constipation can occur, but to avoid affecting the fetus, you must hydrate and eat more vegetables and fruits to correct the symptoms of constipation.
