1. What is Neonatal Weight Loss?

Neonatal weight loss refers to the expected decrease in weight that newborns experience in the first few days after birth. It's normal for babies to lose some weight as they adjust to life outside the womb, but excessive weight loss can indicate feeding problems or other health issues.

2. How Does the Calculator Work?

The calculator uses the following formula:

Where:

• \( \text{Birth Weight} \) — The baby's weight at birth in kilograms
• \( \text{Current Weight} \) — The baby's current weight in kilograms

Explanation: The formula calculates the percentage of weight lost relative to the original birth weight.

3. Importance of Monitoring Weight Loss

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

4. Using the Calculator

Tips: Enter both weights in kilograms. Ensure accurate measurements for reliable results. Typically used in the first 2 weeks of life.

5. Frequently Asked Questions (FAQ)

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

Q2: When should I be concerned about weight loss?
A: If loss exceeds 10%, if baby isn't regaining by day 5, or if there are signs of dehydration (fewer wet diapers, lethargy).

Q3: How often should newborns be weighed?
A: Typically at birth, day 3-5, and at 2 weeks. More frequent if concerns exist.

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

Q5: What factors influence neonatal weight loss?
A: Delivery method, feeding method, maternal fluids during labor, and infant health status.
