Newborn Low Blood Sugar States: Recognition and Management
Newborns can experience a condition called hypoglycemia, which occurs when their blood glucose levels fall below the normal range. This condition can have serious consequences if not detected and treated promptly.
Symptoms of hypoglycemia in newborns may include shakiness, blue or white discoloration of the lips and skin, lack of interest in eating, weak or floppy muscles, low energy, low body temperature, and seizures. Other non-specific symptoms include jitteriness, apnea, sweating, irritability, lethargy, pallor, and seizures.
Causes of hypoglycemia in newborns can be varied. Inadequate food, medical conditions, and antenatal steroids can contribute to this condition. Medical conditions that may cause hypoglycemia include congenital hyperinsulinism, hypothyroidism, galactosemia, fructose intolerance, Beckwith-Wiedemann syndrome, Soto syndrome, and Costello syndrome. Infants of birthing parents with diabetes are more likely to be large for their gestational age, which increases their metabolic and glucose needs, making them more susceptible to hypoglycemia. Similarly, infants who are small for their gestational age have fewer fat stores and less glycogen storage, making them more likely to become hypoglycemic.
Premature babies and late preterm infants, born between 34 and 37 weeks, are particularly at risk due to their inability to produce enough glucose and potential issues with breast milk supply or difficulty nursing. Delayed cord clamping, a practice that allows the placenta to deliver more oxygen and nutrients to the newborn, may offer some protection against hypoglycemia in late preterm infants as a side effect of the steroid medication betamethasone.
Complications during delivery, such as perinatal stress, fetal distress, eclampsia, or hypothermia, can increase the risk of hypoglycemia.
If blood glucose falls below 45 mg/dl in the first 4-24 hours, a doctor may recommend increasing the frequency of feeds to raise blood glucose. Treatment for hypoglycemia in newborns may include giving breast milk, formula, or a mixture of glucose and water. In severe or sustained cases, intravenous dextrose may be administered. For persistent hypoglycemia, medications like diazoxide or hydrocortisone may be used. Close monitoring of blood glucose levels is crucial to prevent brain injury caused by prolonged low glucose.
In rare cases, persistent hypoglycemia requires extensive metabolic and genetic workup to identify treatable underlying causes beyond transient neonatal adaptation.
If an infant shows signs of hypoglycemia after birth, it is essential to call a doctor right away. Early glucose testing after birth can detect hypoglycemia early, allowing treatment to start as soon as possible and reducing the chance that it will cause harm.
