Bloating and gas during late pregnancy are symptoms caused by the uterus pressing on the intestinal canal, and are also related to the pregnant woman’s diet. When a woman enters late pregnancy, the uterus is relatively large due to the development of the fetus, which affects the surrounding organs. Since the intestinal system is located around the uterus, the normal peristaltic function of the intestinal system will be affected after being squeezed by the uterus, and it will not be able to empty the food in the intestine, and the time of food retention in the intestine will be relatively longer. After reacting with the harmful bacteria in the intestine, a large amount of gas will be produced, so many women in late pregnancy will have a bloated stomach, accompanied by the performance of exhaust. There are also some women who have eaten too much gas-producing food. Eating too many soy and dairy products in the diet will cause a lot of gas to be produced in the digestion process, which will also cause the stomach to swell and want to exhaust.
