The main reasons for babies farting with a sour odor are indigestion, intestinal flora disorders, acute gastroenteritis and so on.
1. indigestion: if a baby drinks too much milk and suffers from indigestion, a lot of milk stagnates in the digestive tract and produces a lot of acidic gas when it is fermented, so the fart is a bit acidic.
2. Intestinal dysbiosis: when the dominant bacteria in the baby’s intestinal tract are Escherichia coli and Lactobacillus, the gases released by these strains of bacteria in the decomposition of the baby’s intestinal contents will be foul-smelling and acidic.
3. Acute gastroenteritis: If an infant has an attack of acute gastroenteritis due to eating unclean food, bacterial infection, etc., the intestinal mucosa can produce inflammation and secrete inflammatory secretions under the action of pathogens, resulting in a sour odor in the intestines, and the gases released when farting will also have a sour odor.
There may be other reasons for farting in infants, so it is recommended to go to the hospital in time, complete the examination to clarify the cause of the disease, and then give targeted treatment or therapy under the guidance of the doctor.
