What percentage of weight loss is considered normal for newborns in the early days of life?

• A. 1-3%
• B. 5-10%
• C. 10-15%
• D. 3-5%

Answer: (B)

In the early days of life, it is normal for newborns to lose a certain percentage of their birth weight as they adjust to life outside the womb. A weight loss of 5-10% is considered typical due to several factors, including the baby's transition to feeding, loss of excess fluid, and adjustment to new feeding routines.

During the first week after birth, newborns can lose weight primarily because their initial weight at birth often includes a significant amount of fluid. After delivery, the changes in feeding methods - whether breastfeeding or formula feeding - can also contribute to temporary weight loss as infants learn to feed effectively.

A weight loss of up to 10% is often expected and typically resolves as the baby begins to feed well and regain weight. Monitoring weight loss is crucial because excessive weight loss beyond this range can signal problems such as inadequate feeding, underlying medical issues, or hydration concerns.

In contrast, the lower percentages, such as 1-3% or 3-5%, do not accurately reflect the normative range for neonatal weight loss, whereas a range of 10-15% indicates potential concerns requiring further evaluation. Hence, recognizing the 5-10% weight loss threshold is essential in assessing a newborn's health during this early
