Therefore, it is recommended to minimize the consumption of gas-producing foods such as sweet potatoes, soymilk and carbonated beverages. 2. Gastrointestinal dysfunction: It may be due to irregular diet or unclean diet. It is recommended to have regular meals, combine meat and vegetables, and pay attention to dietary hygiene. 3.
