Symptoms of stomach gurgling in early pregnancy are mainly considered to be caused by functional dyspepsia, because in order to ensure the normal development and growth of the fetus during pregnancy, the stomach, intestines and other organs and tissues of the digestive tract will experience an increased functional burden phenomenon. Part of the food that cannot be decomposed and absorbed in time will have excessive fermentation reaction with harmful bacteria, causing a lot of belching. In addition, due to the slowing down of peristalsis and obstruction of the emptying function, belching will form localized stagnation and cause the expansion of the intestinal lumen space, the flow of gastrointestinal fluids to intensify the situation, so it causes frequent intestinal sound symptoms in pregnant women. This type of patients will also be accompanied by abdominal distension, belching, early satiety, acid reflux, nausea and other concurrent symptoms. However, it is not excluded that pregnant women have irritable bowel syndrome, chronic gastroenteritis, intestinal dysbiosis and other types of diseases.
