The symptoms of total farting in pregnant women may, on the one hand, be related to the normal peristaltic and emptying functions of the gastrointestinal tract due to various factors after pregnancy. On the other hand, it is also related to the change of diet structure of pregnant women. First, the gastrointestinal tract emptying and peristaltic function is weakened. Early in pregnancy, the gastrointestinal tract peristaltic and emptying function will be weakened due to the influence of endocrine function changes in the body. Excessive gas accumulation in the intestine will cause the symptoms of increased anal exhaustion in pregnant women. After the middle and late pregnancy, the size of the uterus gradually increases, which will have a compressive effect on the gastrointestinal tract, and will also affect the normal peristaltic and emptying function of the gastrointestinal tract, causing the performance of increased anal exhaustion. Second, after pregnancy to meet the baby’s growth and development needs, the diet of meat products, dairy products, soy products and other high-protein diet increased, so that the intestinal gas production increased, thus causing increased anal exhaust.
