Hypoglycemia in a Newborn Baby

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 colour to the skin, and breathing and feeding problems.

What Causes Hypoglycemia In A Newborn Baby?

Hypoglycemia can be caused by conditions such as:

· Poor nutrition for the mother during pregnancy

· Making too much insulin because the mother has poorly controlled diabetes

· 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 tumour of the pancreas

· Birth defects

· Congenital metabolic diseases or hormone deficiencies. Some of these run in families.

· Not enough oxygen at birth (birth asphyxia)

· Liver disease

· Infection (certain medicines the mother may have been taking for diabetes at the time of birth, such as sulfonylurea medicines, can cause sepsis or other severe infections)

Which Newborns Are At Risk For 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

· Large for their gestational age

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:

· Shakiness

· Blue colour to skin and lips (cyanosis) or pallor

· Stopping breathing (apnea) or fast breathing

· Low body temperature (hypothermia)

· Floppy muscles (poor muscle tone)

· Not interested in feeding

· Lack of movement and energy (lethargy)

· Seizures

· Weak or high-pitched cry

The signs of hypoglycemia can seem like other health conditions. Make sure your child sees their healthcare provider for a diagnosis.

How Is Hypoglycemia In A Newborn Baby Diagnosed?

A simple blood test for blood glucose levels can diagnose the problem.

How Is Hypoglycemia In A Newborn Baby Treated?

Treatment will depend on your baby's gestational age and overall health. Treatment includes giving the baby a fast-acting source of glucose. This may be as simple as a glucose and water mixture or formula as an early feeding. Or your baby may need glucose given through an IV (intravenous) line. The baby's blood glucose levels are checked after treatment to see if the hypoglycemia occurs again.

What Are Possible Complications Of Hypoglycemia In A Newborn Baby?

The brain needs blood glucose to function. Not enough glucose can harm the brain's ability to function. Severe or long-lasting hypoglycemia may cause seizures and serious brain injury.

What Can I Do To Prevent Hypoglycemia In My Newborn Baby?

In many cases, there may not be a way to prevent hypoglycemia in a newborn baby. For a baby with risk factors, healthcare providers will need to watch carefully for the signs and start treatment as soon as possible. Mothers with diabetes should keep their blood glucose levels in a normal range during pregnancy. This may help lower the risk for their baby.

When Should I Call My Child's Doctor?

Call your baby’s paediatrician right away or get immediate medical care if you see signs of low blood sugar in your baby. Give your baby formula or a glucose and water mixture, if advised.

Key Points About Hypoglycemia In A Newborn Baby

· Hypoglycemia is a condition in which the level of glucose in the blood is lower than normal.

· A baby is at risk if they have a mother with diabetes, is preterm, or is large.

· If your baby has signs of hypoglycemia, give them formula or a glucose and water mixture.

Next Steps

Tips to help you get the most from a visit to your child’s paediatrician:

· Know the reason for the visit and what you want to happen.

· Before your visit, write down questions you want answered.

· At the visit, write down the name of a new diagnosis, and any new medicines, treatments, or tests. Also write down any new instructions your provider gives you for your child.

· Know why a new medicine or treatment is prescribed and how it will help your child. Also know what the side effects are.

· Ask if your child’s condition can be treated in other ways.

· Know why a test or procedure is recommended and what the results could mean.

· Know what to expect if your child does not take the medicine or have the test or procedure.

· If your child has a follow-up appointment, write down the date, time, and purpose for that visit.

· Know how you can contact your child’s doctor after office hours. This is important if your child becomes ill and you have questions or need advice.
