For which condition is a 3-month-old infant showing concern, related to a low birth weight?

A 3-month-old infant exhibiting a rash in the mouth can raise concerns, particularly when considering low birth weight. Infants with low birth weight are at an increased risk for various complications, including nutritional deficiencies and infections. A rash in the mouth could indicate oral thrush, which is caused by an overgrowth of the fungus Candida. This condition is more likely to occur in infants who are immunocompromised or have insufficient nutrition, both of which can be associated with low birth weight. It is essential to recognize and address oral thrush early, as it can impact feeding and overall growth in vulnerable infants.

While acne, respiratory distress, and dehydration can certainly be concerns in pediatric patients, they are not as directly associated with the implications of low birth weight in the same way that oral health issues, such as a rash in the mouth, would be.
