What are the problems associated with babies who are not born at full term?

Children who are not born at full term are generally considered premature infants. Premature babies may experience problems such as low birth weight, weakened immune function, underdeveloped lung function, incomplete digestive system development, and immature intestines. A detailed analysis is as follows:

1. Low Birth Weight

In general, the earlier a premature infant is born, the less subcutaneous fat they have, resulting in lower body weight and less stable vital signs. As a result, the risk of complications is relatively higher.

2. Weakened Immune Function

Premature infants have relatively weak cellular and humoral immunity, as their immune systems are not fully mature. Compared to full-term infants, their immunity and resistance are significantly lower, making them more vulnerable to infections from external factors, such as gastrointestinal or respiratory infections. Therefore, meticulous care is required after birth.

3. Underdeveloped Lung Function

Premature infants often have incompletely developed lungs. If pulmonary surfactant cannot be adequately produced, they may be unable to breathe independently after birth or may frequently experience episodes of apnea. In such cases, prompt mechanical ventilation treatment is necessary.

4. Incomplete Digestive System Development

The gastrointestinal tract of premature infants has not yet fully matured and cannot produce sufficient digestive enzymes, leading to inadequate absorption of nutrients such as fats, carbohydrates, and proteins. Parents can gently massage the infant's abdomen in a clockwise direction or, under medical guidance, administer medications such as *Bacillus subtilis and Enterococcus faecalis* live bacterial granules or pediatric digestive oral solution to aid digestion.

5. Immature Intestines

Premature infants have generally weak organ functions, and their intestinal systems are not fully developed. The immaturity of the gut may lead to feeding intolerance, causing vomiting or necrotizing enterocolitis. Therefore, parenteral nutrition should initially be provided according to medical advice, followed by a gradual transition to normal breastfeeding.

The various physiological indicators of premature infants usually do not meet normal standards. It is recommended to follow medical advice for regular check-ups to monitor growth and development. Daily care should be carefully managed to promote healthy physical development.
