Constipation can occur in early pregnancy due to a variety of factors. The increased secretion of progesterone after pregnancy causes the smooth muscles of the gastrointestinal tract to relax and the intestinal peristalsis to slow down, resulting in constipation due to prolonged residence time of stool in the large intestine; then there is the nausea and vomiting caused by pregnancy reaction. The constipation of material deprivation can also occur due to the decrease in food intake and the lack of fluid. After pregnancy, the family treats pregnant women as a key protection, and does not do anything, not to mention proper activities. Some people are so frightened that they are bedridden, fearing that it will lead to miscarriage. Unbeknownst to them, many people suffer from early pregnancy constipation precisely because of this. With less movement, the muscles in the intestines have a hard time pushing out the feces. Pregnant women tend to consume a lot of protein and fat rich foods and reduce the intake of fruits and vegetables, which leads to a lack of fiber. The reduction in the amount of fiber in the stomach and intestines makes it difficult for feces and impurities to slide down. In addition, prolonged sitting at work will weaken the peristaltic function of the intestines. Poor intestinal peristalsis makes it difficult for food to be digested and absorbed, and the water in the food residue that remains in the intestines for too long will be absorbed. After losing water, the residue eventually becomes dry, hard and difficult to excrete stool. If you are constipated after pregnancy, you must pay attention to a reasonable diet, drink plenty of warm water, and move around properly.
