Abdominal bloating can be quickly eliminated using lactase, domperidone, and intestinal probiotics. Bloating in the abdomen is directly related to slow intestinal peristaltic function and imbalance of intestinal flora, which can be improved by the use of medication. Lactase is an active bacteriocin preparation that enters the intestinal tract and breaks down the sugar in the intestine into lactic acid, which can maintain the acidity of the intestine and inhibit the production of spoilage bacteria. Lactase raw material can prevent the fermentation of proteins in the intestine, inhibit the cause of gas production in the intestine, and also promote digestion. Domperidone coordinates the movement from the esophagus to the small intestine and shortens the time that food is retained in the stomach. It also promotes intestinal peristalsis, allowing the rapid elimination of gas from the intestines. For people who develop intestinal flatulence, they should pay attention to supplementing intestinal probiotics such as Lactobacillus, yeast and bifidobacteria in general. These intestinal probiotics can improve the function of the intestine, promote the absorption of gas in the intestine and reduce the feeling of abdominal flatulence.
