Constipation and excessive exhaustion in late pregnancy are caused by poor digestive function, especially in late pregnancy, as the enlarged uterus will press on the intestines, resulting in poor bowel movement and constipation. The enlargement of the uterus will cause the nearby organs to be squeezed and the gastrointestinal peristaltic function to slow down, which will lead to indigestion, so there will be more exhaust. Due to the poor diet, often eat spicy and stimulating food or eat onions, potatoes, soy products, these foods have a high gas production, not easy to digest, there will be more exhaust. During this period, try to pay attention to a light diet and eat fresh fruits and vegetables in moderation, which is conducive to laxative bowel movements.
