- Poor nutrition of the mother during pregnancy.
- Inadequate feeding intake.
- Blood types of the mother and baby are not compatible.
- Birth defects, endocrine disorders and metabolic diseases present at birth.
- Poor intake of oxygen during birth (birth asphyxia)
Which babies are at higher risk of hypoglycemia?
SGA infants were excluded from analysis due to sample size. Conclusions:Premature infants <33 weeks' gestation have increased risk of hypoglycemia. Maternal hypertension increases hypoglycemia risk. Antenatal magnesium sulfate administration or labor at time of delivery decrease hypoglycemia risk.
What are common causes of low blood sugar in newborns?
Various conditions that might be the causes of low blood sugar in new-born babies include:
- Infants of diabetic mother : Uncontrolled diabetes in the mother results in excessive insulin production. ...
- Premature births: Babies who are born before term are prone to hypoglycaemia.
- Birth weight: Less than 2 kg babies.
- Mothers on certain medications: Like Terbutaline, Propanolol, Labetalol, oral hypoglycaemic agents, etc.
Why do newborns have slightly low blood sugar?
The glucose level can drop if:
- There is too much insulin in the blood. Insulin is a hormone that pulls glucose from the blood.
- The baby is not able to produce enough glucose.
- The baby's body is using more glucose than is being produced.
- The baby is not able to take in enough glucose by feeding.
What causes panhypopituitarism in newborns?
What Causes Hypopituitarism? In children, hypopituitarism is usually caused by something congenital (the child is born with the problem) or by a pituitary tumor. The tumor interferes with the gland. Sometimes, the cause cannot be determined. Congenital. Sometimes, the cause was present before the child was born.
What are 4 common causes of newborn hypoglycemia?
Risk factors include prematurity, being small for gestational age, maternal diabetes, and perinatal asphyxia. The most common causes are deficient glycogen stores, delayed feeding, and hyperinsulinemia. Signs include tachycardia, cyanosis, seizures, and apnea.

Is hypoglycemia curable in newborns?
Hypoglycemia in a newborn is treatable. However, without treatment, this medical condition can cause lasting damage. Parents and caregivers who notice symptoms of hypoglycemia must act quickly. A doctor may recommend giving sugar gel, providing more regular feeds, or supplementing breast milk with formula.
How do you correct hypoglycemia in newborns?
Treatment of Neonatal Hypoglycemia Any neonate whose glucose falls to ≤ 50 mg/dL (≤ 2.75 mmol/L) should begin prompt treatment with enteral feeding or with an IV infusion of up to 12.5% D/W, 2 mL/kg over 10 minutes; higher concentrations of dextrose can be infused if necessary through a central catheter.
How long does neonatal hypoglycemia last?
Usually, low blood glucose levels will only last for a few hours, but can last up to 24-72 hours. Once your baby's levels become normal, he shouldn't have further problems with hypoglycemia (another name for low blood glucose).
What is the first organ affected by hypoglycemia?
The brain is one of the first organs to be affected by hypoglycemia. Shortage of glucose in the brain, or neuroglycopenia, results in a gradual loss of cognitive functions causing slower reaction time, blurred speech, loss of consciousness, seizures, and ultimately death, as the hypoglycemia progresses.
Can Breastfed babies get low blood sugar?
This low blood sugar is normal and not problematic for healthy term breastfed infants without risk factors for hypoglycemia because they have the physiologic resources to generate and rely on ketones as an alternative energy source during the first few days, just like we all do when fasting all night.
Why are preterm infants at risk for hypoglycemia?
Preterm neonates are uniquely predisposed to developing hypoglycemia and its associated complications due to their limited glycogen and fat stores, inability to generate new glucose using gluconeogenesis pathways, have higher metabolic demands due to a relatively larger brain size, and are unable to mount a counter- ...
Why are SGA babies at risk for hypoglycemia?
The SGA babies are more vulnerable to hypoglycemia because of lower glycogen stores and higher energy requirements. Hypoglycemia was 2.3 times more common in babies whose mothers had received intravenous fluids (5% dextrose) during labour.
What causes hypocalcemia in newborns?
Neonatal hypocalcemia usually occurs within the first 2 days of life and is most often caused by prematurity, being small for gestational age, maternal diabetes or hyperparathyroidism, and perinatal asphyxia. Neonates may have hypotonia, tachycardia, tachypnea, apnea, poor feeding, jitteriness, tetany, and/or seizures.
Why do LGA babies have hypoglycemia?
In response, the baby's body makes insulin. All the extra sugar and the extra insulin that is made can lead to fast growth and deposits of fat. This means a larger baby. It also means a risk for low blood sugar right after birth.

Transitional hypoglycemia
A drop in blood glucose is a normal part of the transition to life outside of the uterus. This is known as transitional hypoglycemia. As long as this drop is temporary and mild, it does not typically harm the infant.
Inadequate food
Some infants do not get enough food at birth. This can happen when there are feeding delays, when a parent or caregiver does not feed early or on demand, or when there are issues with breast milk supply.
Medical conditions
There are a variety of medical conditions that can cause difficulty feeding in newborns or difficulty absorbing and storing energy. This can be a cause of persistent hypoglycemia.
Antenatal steroids
According to a 2020 study, hypoglycemia is a common side effect of the steroid medication betamethasone. Sometimes, doctors give a single course of this drug to pregnant people who are at risk of preterm birth, as it speeds up fetal lung development.
Large size at birth
Infants who are large for their gestational age have higher metabolic and glucose needs. This can raise the likelihood of hypoglycemia, as they may not get as much glucose as they need from breastmilk or formula.
Small size at birth
Infants who are small for their gestational age have fewer fat stores and less glycogen storage. This means that they are less able to produce glucose and are more likely to become hypoglycemic, especially if there are other issues, such as delayed feeding.
Prematurity
Premature babies have similar issues to small infants. They may not produce enough glucose. They may also experience difficulty nursing or issues with a breast milk supply.
Which babies are more likely to have hypoglycemia?
Babies who are more likely to have hypoglycemia include those who are: Born to mothers with diabetes. Small for gestational age or growth-restricted. Preterm babies, especially those with low birth weights. Born under significant stress. Born to mothers treated with certain medicines such as terbutaline.
What are the symptoms of hypoglycemia in a newborn baby?
Signs of low blood sugar may not be easy to see in newborn babies. The most common signs include:
How is hypoglycemia in a newborn baby diagnosed?
A simple blood test for blood glucose levels can diagnose the problem.

What causes incompatible blood types in a newborn?
Incompatible blood types of mother and baby (severe hemolytic disease of the newborn) More insulin in the baby's blood for other reasons, such as a tumor of the pancreas. Birth defects. Congenital metabolic diseases or hormone deficiencies. Some of these run in families.
Why is my newborn's blood sugar low?
It can cause problems such as shakiness, a blue color to the skin, and breathing and feeding problems.
What are the risks of hypoglycemia in newborns?
Some newborns have certain risk factors that make it easier for them to develop neonatal hypoglycemia. These may include: 1 Being born too early 2 Infection 3 Need for oxygen after delivery 4 Mother with diabetes 5 Having a slow growth while in the womb 6 Being smaller or larger in size than normal 4
How to treat hypoglycemia in neonates?
Treatment of neonatal hypoglycemia depends on the presence of hypoglycemia symptoms, breast milk supply , and the ability to nurse or feed with a bottle and formula. Newborns with low blood sugar will need extra breast milk or formula feedings. Some newborns may need a sugar solution (glucose) intravenously, or through a vein, especially if the baby is unable to feed by mouth or if blood glucose is very low. 5
How to diagnose neonatal hypoglycemia?
Diagnosis of neonatal hypoglycemia is done with a serum glucose test. It is a blood test that measures blood sugar in a newborn using a heel stick, an easy and minimally invasive way do blood work for newborns where blood is drawn from the heel of the foot.
What is the blood glucose level of a newborn?
In newborns, a blood glucose level of 30 mg/dL (milligrams per deciliter) in the first 24 hours of life and less than 45 mg/dL constitutes neonatal hypoglycemia. Symptoms of neonatal hypoglycemia are not always obvious in a newborn. Moreover, each newborn may experience symptoms differently.
Why does blood sugar drop in newborns?
Some newborns have certain risk factors that make it easier for them to develop neonatal hypoglycemia. These may include:
What is the term for a newborn's blood sugar levels?
A Word From Verywell . Neonatal hypoglycemia, or low blood sugar in a newborn, occurs when a newborn’s blood glucose levels are less than the baby’s body needs. Glucose is the main fuel source for the body and brain. In a newborn, low blood sugar has many causes. It can also cause problems, including breathing and feeding issues.
How many babies are born with hypoglycemia?
Neonatal hypoglycemia affects up to about 4 per 1,000 full-term births according to some studies. 1 It is usually associated with risk factors, including the mother’s age at the time of birth, if the mother is diabetic, or if the baby is too small or too large.
What is hypoglycemia in a newborn baby?
Hypoglycemia is when the level of sugar (glucose) in the blood is too low. Glucose is the main source of fuel for the brain and the body. In a newborn baby, low blood sugar can happen for many reasons. It can cause problems such as shakiness, a blue color to the skin, and breathing and feeding problems.
What are possible complications of hypoglycemia in a newborn baby?
Not enough glucose can harm the brain's ability to function. Severe or long-lasting hypoglycemia may cause seizures and serious brain injury.
How is hypoglycemia in a newborn baby diagnosed?
A simple blood test for blood glucose levels can diagnose the problem.
Why is hypoglycemia so severe in infants?
Infants are at risk for more severe or prolonged hypoglycemia due to one or a combination of the following underlying mechanisms: insufficient glucose supply, with low glycogen or fat stores or poor mechanisms of glucose production; increased glucose utilization caused by excessive insulin production or increased metabolic demand; or the failure of counter-regulatory mechanisms (i.e., pituitary or adrenal failure). [12][11]Neonatal hypoglycemia most commonly affects the following groups of infants [3]:
What is the risk of hypoglycemia in a diabetic infant?
Infants of diabetic mothers (IDM) and large for gestational age infants experience fetal hyperinsulinism and increased peripheral glucose utilization, putting them at risk for hypoglycemia in the immediate postnatal period. [1][4][12]The placenta supplies the fetus with a direct source of glucose via facilitated diffusion, such that fetal glucose concentrations are proportional to maternal levels. Prolonged elevations in maternal glucose concentrations result in fetal hyperglycemia and pancreatic overstimulation to increase endogenous fetal insulin production.[12] These elevated levels of fetal insulin persist after birth and, in the absence of a continuous exogenous glucose source, result in increased glucose utilization and lower blood glucose concentrations.[12] IDM have a decreased ability to mobilize glycogen stores after birth and experience a relative adrenal insufficiency with decreased levels of catecholamines, further contributing to the risk of low blood glucose levels.
What happens to blood glucose after birth?
Healthy infants experience an expected drop in blood glucose concentrations immediately following birth as a part of the normal physiologic transition to extrauterine life. Abruptly clamping the umbilical cord at birth disrupts the infant's connection to the placenta, upon which it relied to supply glucose and other metabolites necessary to meet its energy needs in utero. The continuous supply of exogenous intravenous glucose from the placenta suddenly ceases, and the infant's blood glucose concentration declines in the first hours of life. For most healthy infants, this transitional neonatal hypoglycemia is brief, transient and most often asymptomatic. [4][11]
Why are preterm infants at risk for hypoglycemia?
Preterm, intrauterine growth restricted and small for gestational age infants are at risk for hypoglycemia because they are born with decreased glycogen stores, decreased adipose tissue and experience increased metabolic demands because of their relatively large brain size . [1][12]In very low birth weight (<1000 g) preterm infants, the enzymes involved in gluconeogenesis are expressed at low levels; thus their ability to produce endogenous glucose is poor, contributing to their risk of severe or prolonged low glucose concentrations. [12]
How long does it take for glucose to go down in an infant?
Despite a better understanding of early glucose homeostasis and transitional hypoglycemia in the first 48 hours of life, gaps in our knowledge persist. Observations have shown that healthy infants experience transient hypoglycemia as a part of the normal adaption to extrauterine life, with a decline in blood glucose concentrations to values as low as 20 to 25 mg/dL in the first two hours of life.[1] However, because we do not routinely measure blood glucose concentrations in healthy infants without risk factors for hypoglycemia, it is difficult to define 'normal' levels of blood glucose in the first 48 hours of life. As Harding et al. question: "even if healthy infants experience low glucose concentrations, can we extend these values to infants at risk of impaired metabolic adaption?" [5]And how low is too low?
What is the most common metabolic disturbance occurring in the neonatal period?
Hypoglycemia is the most common metabolic disturbance occurring in the neonatal period. Screening at-risk infants and the management of low blood glucose levels in the first hours to days of life is a frequent issue in the care of the newborn infant. Yet, a clear definition of neonatal hypoglycemia is lacking. Current screening guidelines and management algorithms are based on limited evidence, relying more on expert opinion to guide recommendations. This activity reviews neonatal hypoglycemia and the need to develop an improved knowledge of it. This activity highlights the role of the interprofessional team in the recognition and management of neonatal hypoglycemia.
What is the treatment for severe hypoglycemia?
Symptomatic hypoglycemia or severe hypoglycemia requiring treatment with intravenous dextrose
