What percentage of weight loss is considered normal in newborns?

• A. 3-5%
• B. 5-7%
• C. 7-10%
• D. 10-15%

Answer: (B)

In newborns, a weight loss of 5-7% from their birth weight is considered normal and expected in the first few days after delivery. This temporary loss is primarily due to the elimination of excess fluid that the infant accumulates in utero, as well as the transition from receiving nutrients through the placenta to feeding independently.

Most infants typically regain their birth weight by about two weeks of age. The range of 5-7% allows for normal physiological variations among babies, including factors such as feeding difficulties, initial fluid loss, and maternal factors. Losses greater than 7% may raise concerns about the infant's feeding adequacy or health, necessitating closer observation and potential intervention.

Understanding this percentage helps healthcare providers to monitor newborns' health effectively and to provide guidance and support to new parents, ensuring that babies are on track for healthy growth and development.
