Why does a 1-month-old baby lose weight?

The real reply from the in-app AI advisor

Weight loss in a 1-month-old baby is not normal and must always be evaluated. Some physiological weight loss is expected in the first days after birth (5-7%, sometimes up to 10%), but this is usually regained within 10-14 days. If your baby is still losing weight at 1 month old, the main causes may be:

  • Inadequate nursing or insufficient breast milk supply (frequent nursing and close follow-up are needed until weight returns)
  • Ineffective nursing (tongue tie, difficulty nursing)
  • Reflux or frequent spitting up (prevents nutrients from being retained)
  • Metabolic or digestive system problem (rare but must be ruled out)
  • Infection (UTI can start insidiously)

This situation requires prompt pediatric evaluation. Additionally, if baby has fever, lethargy, tendency to sleep excessively, or decreased urine output, do not delay — go to the emergency room.
