1. What is Percent Weight Loss?

Percent weight loss is a calculation used to monitor newborn weight changes in the early days after birth. It compares the current weight to the birth weight to determine what percentage of weight has been lost.

2. How Does the Calculator Work?

The calculator uses the following formula:

Where:

• \( \text{birth weight} \) — Newborn's weight at birth (grams)
• \( \text{current weight} \) — Newborn's current weight (grams)

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 in newborns is crucial as excessive weight loss (>10%) may indicate feeding problems or other medical issues requiring intervention.

4. Using the Calculator

Tips: Enter both weights in grams. Ensure measurements are accurate and taken at consistent times (preferably before feeding at the same time each day).

5. Frequently Asked Questions (FAQ)

Q1: What is normal weight loss for a newborn?
A: Most newborns lose 5-7% of birth weight in first few days, typically regaining birth weight by 10-14 days of age.

Q2: When should I be concerned about weight loss?
A: Consult a pediatrician if weight loss exceeds 10% or if baby isn't regaining weight by day 5-7.

Q3: How often should weight be measured?
A: First weight should be measured at birth, then daily for first week if there are concerns, otherwise every few days.

Q4: Does this apply to premature babies?
A: Premature babies may have different weight loss patterns - consult your neonatologist for specific guidance.

Q5: What affects newborn weight loss?
A: Factors include feeding method (breast vs formula), maternal milk supply, baby's ability to feed effectively, and fluid balance.
