What causes constipation in babies who drink formula milk?

Baby constipation caused by drinking formula may be due to various reasons. 1. It could be due to formula intolerance; the baby may have intolerance to proteins in the formula, leading to gastrointestinal dysfunction and symptoms such as constipation and bloating. 2. Indigestion is another common cause; if the baby consumes excessive amounts of formula regularly, it can increase the burden on the gastrointestinal tract and slow intestinal motility, thus causing constipation. 3. Constipation may also occur if the baby is allergic to cow's milk protein or has lactose intolerance. 4. The way formula is prepared can also affect the baby's digestion; preparing the formula too concentrated may lead to constipation. 5. Individual differences and the intestinal health status of the baby are also among the factors influencing constipation. Parents should take corresponding measures based on the baby's specific situation to improve the condition.
