1. What is Birth Weight Loss Percentage?

The birth weight loss percentage calculates how much weight a newborn has lost compared to their birth weight. It's an important metric for assessing neonatal health and feeding adequacy in the early days after birth.

2. How Does the Calculator Work?

The calculator uses the following formula:

Where:

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

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

3. Importance of Monitoring Weight Loss

Details: Monitoring weight loss helps identify feeding problems, dehydration, or other health issues. Most newborns lose 5-7% of birth weight in first few days and regain it by 10-14 days.

4. Using the Calculator

Tips: Enter both weights in kilograms (kg). Ensure measurements are accurate and taken at consistent times (preferably before feeding).

5. Frequently Asked Questions (FAQ)

Q1: What is considered normal weight loss after birth?
A: 5-7% loss is typical for vaginal births, up to 10% for C-sections. More than 10% loss warrants evaluation.

Q2: When should I be concerned about weight loss?
A: If loss exceeds 10% of birth weight or continues beyond 5 days without regain.

Q3: How often should weight be checked?
A: Daily in first week if concerns exist, otherwise at pediatric visits (day 3-5 and 2 weeks).

Q4: Does breastfeeding affect weight loss?
A: Breastfed babies may lose slightly more initially but should follow similar regain patterns.

Q5: What if my baby loses more than recommended?
A: Consult pediatrician to assess feeding, hydration, and possible supplementation needs.
