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

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.
