Why is a higher-calorie formula or fortified breast milk recommended for infants with congenital heart disease?

• A. Easier digestion
• B. Weight gain and energy conservation
• C. Reduces reflux
• D. Improves immune function

Answer: (B)

In infants with congenital heart disease, meeting growth needs efficiently is essential because the heart condition increases energy expenditure and feeding can become tiring or limited by fluid restrictions. A higher-calorie formula or fortified breast milk delivers more calories per ounce, so adequate daily calories and weight gain can be achieved with smaller or fewer feeds. This helps the baby grow despite the extra energy the body uses for the heart and lungs, and it can reduce the total volume the infant must take, which supports fluid balance and comfort during feeds. It’s not primarily about digestion ease, reflux reduction, or immune function; those may be influenced by other factors, but the main purpose of increasing caloric density is to promote weight gain and conserve energy overall.
