What is the reason why my stomach moves like a fetus when I am not pregnant?

No pregnancy belly like fetal movement is the result of intestinal spasms, intestinal obstruction, enteritis disease, etc. Episodes of intestinal spasms are associated with a variety of factors and are mainly manifested by spasmodic contractions of the smooth muscles of the intestine during the onset of the disease. During an episode of intestinal spasm, there is a strong localized contraction of the intestine that looks like a sensation of fetal movement. Intestinal obstruction is caused by blockage of the intestine and inability to expel the contents. An attack of intestinal obstruction is accompanied not only by excessive dilatation of the intestinal lumen but also by hyperactive bowel sounds. When the gas in the intestinal cavity passes through the chyme and the fluid in the intestine, it causes a slight fluctuation in the intestine, and a sensation like fetal movement may occur. During an attack of enterocolitis, the main manifestation of the disease is hyperactive intestinal peristalsis and dysfunction. Due to the high tension of intestinal peristalsis, the sensation of fetal movement in the abdomen can be clearly felt, accompanied by symptoms such as abdominal distension and diarrhea.
