Patient's question:
My baby is a premature infant, and I'm very concerned about her health. I want to know what the weight standard is for premature infants?Doctor's answer:
The weight of premature infants begins to recover 5 to 6 days after birth and returns to birth weight within 7 to 10 days. If the birth weight is less than 1500 grams, it gradually returns to birth weight within 2 to 3 weeks. After premature infants regain their birth weight, they need to gain 10 to 30 grams per day, with a more precise calculation being 15 to 20 kilograms. Parents of premature infants can monitor their weight gain weekly after discharge. If the growth is too slow, they should seek medical attention promptly.
