Protecting your baby from getting a low blood sugar (Hypoglycaemia) 

Low blood sugar (also called hypoglycaemia) happens when there is not enough glucose (sugar) in your baby’s blood.

Your baby may be at higher risk if they:

  • Were born small
  • Were born early (prematurely)
  • Were unwell at birth
  • You have diabetes
  • You needed to take certain medicines during pregnancy, such as beta-blockers

Most babies with low blood sugar recover quickly if it is picked up and treated early.

Very low blood sugar that is not treated can sometimes cause serious problems, including brain injury and developmental difficulties.
