1. What is Infant Weight Loss Percentage?

The infant weight loss percentage calculation measures how much weight a newborn has lost compared to their birth weight. This is an important metric in neonatal care as excessive weight loss can indicate feeding problems or other health issues.

2. How Does the Calculator Work?

The calculator uses the following formula:

Where:

• Birth Weight — The infant's weight at birth (kg)
• Current Weight — The infant's current weight (kg)

Explanation: The formula calculates what percentage of the original birth weight has been lost.

3. Importance of Monitoring Weight Loss

Details: Monitoring weight loss in newborns is crucial as excessive loss (>10%) may indicate inadequate feeding, dehydration, or other medical issues that require intervention.

4. Using the Calculator

Tips: Enter both weights in kilograms (kg). For accurate results, weigh the infant at the same time of day using the same scale. Both values must be positive numbers.

5. Frequently Asked Questions (FAQ)

Q1: What is normal weight loss for newborns?
A: Most newborns lose 5-7% of birth weight in first few days, with 10% generally considered the upper limit of normal.

Q2: When should I be concerned about weight loss?

Q3: How often should I weigh my newborn?
A: In first 2 weeks, daily weights may be recommended for infants with feeding issues. Otherwise, follow your pediatrician's advice.

Q4: When do babies typically regain birth weight?
A: Most infants regain birth weight by 10-14 days of age with adequate feeding.

Q5: Does this apply to premature infants?
A: Premature infants may have different weight loss patterns - consult your neonatologist for guidance specific to preemies.
