Which of the following is a common symptom of a newborn experiencing hypoglycemia?

• A. Euphoria and excessive weight gain
• B. Difficulty feeding or lethargy
• C. Signs of dehydration only
• D. Extreme vigor or alertness

Answer: (B)

The symptom of difficulty feeding or lethargy is commonly associated with newborns experiencing hypoglycemia because low blood sugar affects their energy levels and ability to feed. Infants with hypoglycemia often display signs of weakness, tiredness, or a lack of alertness, which can make it challenging for them to feed effectively.

When blood glucose levels drop, the brain and other organs may not receive adequate energy, leading to lethargy. This may manifest as a baby appearing floppy, disinterested in feeding, or having difficulty staying awake during feedings. Recognizing this symptom is crucial, as early intervention can help prevent potential complications associated with hypoglycemia.

In contrast, the other options present symptoms that do not correlate with hypoglycemia. Reports of euphoria, excessive weight gain, and extreme vigor or alertness would typically indicate that the infant is well-nourished and has sufficient energy. Similarly, signs of dehydration alone do not directly connect to hypoglycemia, which focuses more on energy availability rather than fluid balance. Understanding these associations is important for identifying and managing potential hypoglycemia in newborns effectively.
