1. What is Birth Weight Percentage Loss?

The birth weight percentage loss calculates how much weight a newborn has lost relative to their birth weight. This is an important metric in neonatal care to monitor adequate feeding and hydration.

2. How Does the Calculator Work?

The calculator uses the following equation:

Where:

• \( \text{Birth Weight} \) — Baby's weight at birth (kg)
• \( \text{Current Weight} \) — Baby's current weight (kg)

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

3. Importance of Weight Loss Calculation

Details: Monitoring weight loss helps identify babies who may need additional feeding support. Excessive weight loss (>10%) may indicate dehydration or feeding problems.

4. Using the Calculator

Tips: Enter birth weight and current weight in kilograms. Both values must be positive numbers. Weights should be measured using calibrated scales.

5. Frequently Asked Questions (FAQ)

Q4: Does this apply to premature babies?
