Infant flatulence is mostly considered to be caused by immature development of gastrointestinal function and cold, etc. It is usually recommended to take probiotics such as Bifidobacterium bifidum, Bacillus licheniformis, Lactobacillus acidophilus and so on. 1. Bifidobacterium bifidum: Bifidobacterium bifidum probiotic contains a certain amount of Lactobacillus acidophilus, Enterococcus faecalis, Bacillus cereus and so on. These ingredients are more in line with the structure of infant intestinal flora, and at the same time can help to improve lactose tolerance of dairy products, promote digestion, and improve infant flatulence and other symptoms. 2. Bacillus licheniformis: Bacillus licheniformis promotes the growth of bifidobacteria and other beneficial bacteria, but also has an antagonistic effect on pathogenic bacteria such as staphylococci, etc., which is helpful in regulating the intestinal flora, and is helpful in relieving flatulence in infants. 3. Lactobacillus acidophilus: Lactobacillus acidophilus can increase intestinal acidity by breaking down sugar into lactic acid, which helps to regulate intestinal flora and improve symptoms of flatulence and other discomforts. All of the above medications need to be used under the guidance of a doctor, not self-medication. Infant flatulence may also be related to other causes, should go to the hospital in order to clarify the cause of the disease, standardize the treatment, and follow the doctor’s instructions for medication.
