1. What is Neonatal Weight Loss Percentage?

The neonatal weight loss percentage calculates how much weight a newborn has lost compared to their birth weight. This is particularly important in the first days of life when some weight loss is expected, but excessive loss may indicate problems.

2. How Does the Calculator Work?

The calculator uses the formula:

Where:

• \( birth\_weight \) — Baby's weight at birth (kg)
• \( current\_weight \) — Baby's current weight (kg)

Explanation: The formula calculates what percentage of the birth weight has been lost in the current measurement.

3. Importance of Monitoring Weight Loss

Details: Monitoring weight loss helps identify excessive loss that may indicate feeding difficulties, dehydration, or other health issues. In India, where neonatal care is crucial, this calculation is particularly important.

4. Using the Calculator

Tips: Enter birth weight and current weight in kilograms. Both values must be positive numbers. The calculator will show the percentage of weight lost.

5. Frequently Asked Questions (FAQ)

Q1: What is normal weight loss for a neonate?
A: Typically 5-7% in first 3-5 days, up to 10% may be normal for breastfed infants. More than 10% may require evaluation.

A: If loss exceeds 10%, if weight loss continues beyond 5 days, or if baby shows signs of dehydration.

Q3: How often should weight be measured?
A: Daily in first week for high-risk infants, every 2-3 days for healthy newborns until birth weight is regained.

Q4: Are there special considerations for Indian neonates?
A: Yes, Indian neonates may have different growth patterns. Always consult with a pediatrician familiar with local growth standards.

Q5: When should birth weight be regained?
A: Most babies regain birth weight by 10-14 days of age. If not, medical evaluation is recommended.
