Disease description:

My child is a premature baby. During a recent health checkup, we found that his weight is not increasing, although he is feeding normally. What could be the reasons for a premature infant's lack of weight gain?

Dr. Xie Zixing
A premature infant's failure to gain weight may be due to the incomplete development of various bodily functions and low immune function, making the infant more susceptible to bacterial or viral infections that can lead to loss of appetite. It could also be associated with anemia in the premature infant, contributing to poor weight gain. If there is insufficient breast milk and the infant consumes less milk, resulting in a state of hunger, this usually affects normal growth and development and leads to inadequate weight gain.
