Overview
High blood sugar occurs when the sugar (glucose) level in the blood rises above your child's target range. It can happen if your child:
- Misses a dose of insulin or diabetes medicine.
- Eats more than usual.
- Is under emotional stress.
- Has an illness, such as the flu or an infection.
- Takes a medicine that raises blood sugar as a side effect. Examples include medicines that reduce inflammation (corticosteroids) and some decongestants.
- Starts puberty. Hormonal changes affect how well the body uses insulin. These changes can cause higher blood sugar levels.
Some children who take insulin may have very high blood sugar in the morning, even if it was low at bedtime. This could be caused by the dawn phenomenon. Talk with your child's doctor if this happens.
