Acute gastroenteritis flatulence is related to the presence of inflammation and gastrointestinal dysfunction in the gut. Most episodes of acute gastroenteritis are caused by inflammation of the gastrointestinal mucosa, because inflammation leads to congestion and edema of the gastrointestinal mucosa, so the patient will experience flatulence in the digestive system. When inflammation stimulates the smooth muscle of the digestive system, it leads to hyperperistalsis of the smooth muscle, and this process generates a lot of gas, and there is flatulence. Since inflammation also affects the function of the intestine and stomach, the absorption function of the intestinal wall cells for gas will be affected, and the gas in the intestine cannot be absorbed by the intestinal wall cells and enters the body’s blood circulation will gather in the intestinal cavity in large quantities, and there will also be gastrointestinal flatulence. The symptoms of flatulence caused by acute gastroenteritis can generally be improved after the inflammation is eliminated and the intestinal function is restored. During this period, medications such as montelukast, enteritisin, and intestinal probiotics can be used to help the recovery of the condition.
