Hiccups all the time in pregnant women are related to diaphragm irritation, indigestion and chronic gastritis. After pregnancy, because of the development of the fetus, the uterus of a woman will gradually increase in size, which leads to the squeezing of the organs in the abdomen. After the stomach is squeezed by the uterus, it causes some stimulation to the surrounding organs, especially when the stomach causes stimulation to the diaphragm, it will lead to spasm of the diaphragm, so the performance of hiccups appears all the time. Some pregnant women suffer from indigestion due to emotional tension, stress, slow stomach movement, etc. When indigestion occurs, hiccups occur due to the prolonged presence of food in the stomach and the production of large amounts of gas with the digestive juices. Some pregnant women are accompanied by chronic gastritis, which not only affects the digestive function of the stomach, but also contracts and spasms when stimulated by gastric acid, and hiccups may also occur.
