Why does my baby have diarrhea after drinking formula milk?

Diarrhea in infants after consuming formula milk may be caused by various factors. 1. It could be due to indigestion, possibly resulting from formula that is too thick or the infant's own weak digestive capacity. 2. Improper feeding is another common cause, such as feeding excessive amounts of formula at once, which may overwhelm the infant's digestive capacity. 3. Certain components in the formula may irritate the infant's intestines or trigger allergies, such as cow's milk protein allergy, which may lead to irritable bowel syndrome. 4. Failure to properly clean and disinfect feeding bottles and other formula preparation equipment, or inappropriate formula temperature, may also cause diarrhea in infants. 5. Medical conditions such as gastroenteritis and lactose intolerance can also cause diarrhea symptoms. When an infant experiences diarrhea after consuming formula, parents should carefully observe and identify potential causes, consulting a doctor and taking appropriate measures when necessary.
