Some women are prone to overeating after pregnancy, and some have pregnancy reactions, nausea, vomiting, and significantly reduced eating. These factors can lead to a decrease in intestinal food residues, which reduces the stimulation of the colon and weakens intestinal peristalsis, resulting in defecation dysfunction; on the other hand, it can lead to an imbalance of electrolyte balance in the body, hypokalemia and vitamin deficiency in the body, which can also lead to defecation dysfunction. There are also women who are afraid of miscarriage after pregnancy or have had miscarriage for fear of miscarriage again, resulting in weakening of abdominal muscles, diaphragm, and anal muscles and weakness of defecation, which can also lead to constipation. Therefore, pregnant women should try to overcome the partial diet, if there is a pregnancy reaction, should take appropriate treatment measures to improve the diet, and eat more vegetables, fruits and other fiber-rich foods, and make appropriate activities to ensure that the abdominal muscles, diaphragm, anal raphe muscles have appropriate exercise, in order to promote defecation and prevent the occurrence of constipation. If a pregnant woman is already suffering from constipation, try not to use laxatives, because most laxatives have the possibility of causing uterine contractions, which may lead to miscarriage, and some laxatives have certain toxic side effects, which may affect fetal development. Therefore, the main treatment is to adjust the diet, correct bad bowel habits and appropriate activities, and if necessary, use appropriate Chinese medicine treatment, or use western medicine enema treatment with less toxic side effects is appropriate.
