Incomplete intestinal obstruction intestinal partially blocked, larger food residues or feces can not be easily discharged, the gas is easier to pass. Patients with incomplete intestinal obstruction have increased gas production and increased exhaust due to excessive accumulation of food and feces in the intestines, resulting in fermentation of the food and feces. Incomplete intestinal obstruction patients with intestinal flora disorders, harmful bacteria and food debris fermentation gas production, resulting in increased exhaust. And due to the flora disorder, opportunistic infectious bacteria infect the intestines to cause inflammation of the intestines, intestinal peristalsis increases, and exhaust gas increases.
