When a pregnant woman has constipation, it is recommended to adjust the diet structure in a timely manner, exercise appropriately, and take lactulose orally to help defecate when the constipation is serious. As the hormone level of pregnant women increases during pregnancy, and with the gradual increase in the size of the fetus, it will lead to edema of the gastrointestinal mucosa, so pregnant women are prone to constipation during pregnancy. Pregnant women should eat more fiber-rich foods, such as apples, yogurt, beans, etc., and take physical exercise after meals to keep the gastrointestinal flora in a balanced state and prevent aging of the intestines. In case of severe constipation with hemorrhoids or blood dripping, you can take oral lactulose to help defecate or take medication under the guidance of a doctor, not blindly take medication to prevent the impact on the growth and development of the fetus.
