What is the normal weight loss percentage range for preterm infants in the first week?

• A. 0-5%
• B. 5-10%
• C. 10-15%
• D. 15-20%

Answer: (C)

In preterm infants, there is a normal amount of fluid loss after birth due to fluid shifts and the immaturity of their systems to regulate intake and losses. The typical weight loss in the first week is about 10-15% of birth weight. For example, a preterm baby born at 1200 g may lose roughly 120–180 g during the first week. This weight drop usually reaches a low point around days 3–5 and then weight begins to rebound as feeding becomes established, with many babies returning to or exceeding birth weight over the next week or two depending on maturity and nutrition. To support this process, ensure adequate caloric intake, using fortified feeds if necessary, and monitor daily weights carefully using consistent conditions. If the infant’s weight loss approaches or exceeds 15% or there is no weight regain after the initial drop, evaluate for insufficient intake, feeding intolerance, or excessive losses and adjust the feeding plan accordingly.
