What is the maximum physiologic weight loss considered normal for term neonates in the first days of life?

• A. 10%
• B. 5%
• C. 15%
• D. 20%

Answer: (A)

Term neonates commonly shed some weight in the first days as they lose extracellular fluid and begin feeding reliably. This physiologic weight loss can be up to about 10% of birth weight. It typically peaks around day 2–3, and most infants regain their birth weight within the first week or two. If weight loss approaches or exceeds 10% or continues beyond the first week, it may indicate insufficient intake, dehydration, or another issue and should prompt evaluation of feeding effectiveness, latch, feed frequency, and hydration. So, the maximum considered normal in the early days is about 10%.
