The constant urge to defecate in pregnancy is mainly related to uterine pressure on the rectum or ectopic pregnancy conditions, which can be taken care of on a daily basis and, if necessary, promptly treated by a doctor. In early pregnancy, as the uterus increases, it will press on the rectum and cause a feeling of stool, but after 3 months of pregnancy, the size of the uterus exceeds the pelvic cavity, the pressure will be reduced, and the feeling of stool will also be reduced; in late pregnancy, when the fetal head is in the pelvis, it will also press down on the rectum and cause a strong feeling of stool. These are normal phenomena and no special treatment is needed. In daily life, you can do appropriate exercises such as walking and yoga, drink more warm water and supplement coarse fiber food to stimulate gastrointestinal peristalsis and promote defecation; eat more fresh fruits and vegetables to maintain a balanced nutrition and supplement multivitamins to improve the body’s immunity; adjust your eating habits, eat less and more often and not too full. However, we should be alert to the fact that if the ultrasound in early pregnancy cannot clearly identify the pregnancy as intrauterine, the rupture and miscarriage of ectopic pregnancy may cause intra-abdominal bleeding, stimulate the rectum and cause bowel movement, accompanied by abdominal distension and abdominal pain and other discomforts, so we need to seek medical attention promptly and terminate the pregnancy under the guidance of a doctor. If the paroxysmal abdominal pain in late pregnancy is accompanied by strong bowel movements, it may also be a sign of impending labor and requires prompt medical attention. Most of them are normal during pregnancy, as long as all the obstetrical examinations are normal and you pay attention to good health care during pregnancy.
