Constipation in late pregnancy may be mainly related to the increase in estrogen and progesterone levels, uterine pressure on the intestines, which can be improved by improving diet, proper exercise, drinking more water, etc. In serious cases, you can go to the hospital for enemas or drug treatment. Common causes: 1. Increased estrogen and progesterone levels: Increased estrogen and progesterone in late pregnancy can reduce gastrointestinal motility, making gastrointestinal peristalsis weakened, coupled with reduced exercise in late pregnancy, more likely to cause constipation; 2. Uterine pressure on the intestines: the uterus continues to increase in late pregnancy, increasing pressure on the sigmoid colon and rectum, playing a compressive role, easily causing constipation. Treatment: 1, improve diet: eat less and more meals, eat more dietary fiber and fruits and vegetables, such as green vegetables, oranges, carrots, bananas, celery, etc.; eat less greasy, animal offal and other foods; 2, appropriate exercise: moderate activities according to preference, such as walking, yoga, etc., to promote gastrointestinal tract peristalsis and relieve constipation symptoms; 3, drink more water: drinking more water can promote metabolism, to achieve the purpose of laxative; 4. Enema or medication: for patients with severe constipation, often accompanied by abdominal pain and bloating, which affects normal life, should promptly go to the hospital, under the guidance of the doctor for enemas and medication, such as corkage, lactulose, etc. Note: During the late pregnancy, you must strengthen fetal monitoring and do maternity checkups on time; try to sleep in a left-sided position to reduce pressure; relax and face the birth positively.
