Infants with intestinal flatulence may be related to excessive air inhalation, excessive protein intake, inadequate gastrointestinal function and intestinal inflammation, which can be improved by changing living habits and taking appropriate medication. 1. Excessive air inhalation: babies inhale a lot of air when drinking milk, laughing or crying, which accumulates in the intestine and is difficult to expel. Parents can help the baby gently massage the abdomen, or hot compress with a hot water bag to help air expulsion; 2, too much protein intake: If the baby drinks more milk, or consumes milk powder with high protein content, or breastfeeding mothers consume more food containing protein, it will easily cause flatulence. As babies grow up and add complementary foods, flatulence will be relieved on its own; 3. Insufficient gastrointestinal tract function: the intestinal tract function of infants is not yet developed, digestion and absorption are poor, milk and food accumulate in the intestine too late to digest, it will decompose gas and form flatulence. Probiotics can be appropriately given to babies to help them digest as soon as possible; 4, intestinal inflammation: the intestine is infected by bacteria or viruses, resulting in intestinal flora imbalance, food fermentation in the intestine leads to intestinal flatulence, children can be accompanied by diarrhea symptoms, should promptly seek medical advice to identify the causative agent, viral infections generally do not need to apply antiviral drugs, bacterial infections can be treated with antibiotics under medical advice, if the diarrhea is serious can be applied If the diarrhea is severe, you can apply montelukast to stop the diarrhea. Breastfeeding mothers should pay attention to their dietary structure and avoid consuming too much food that can easily cause flatulence. You need to find the right position when breastfeeding to reduce the possibility of your baby inhaling air.
