sugar, also called hyperglycemia, occurs when the sugar (glucose) level in the
blood rises above normal. For a person who has
diabetes, high blood sugar may be caused by missed
diabetes medicine or insulin injection, eating too much, skipping physical
activity, or illness or stress. The rapid growth during the teen years can also
make it harder to keep your child's blood sugar levels within a target
blood sugar, high blood sugar usually develops slowly over a period of hours or
days. But it can also develop quickly (in just a few hours) if you eat a large
meal or miss an insulin dose. Blood sugar levels just above the target range may
make a person feel tired and thirsty. If your child's blood sugar level stays
higher than normal, his or her body will adjust to that level. Over time, high
blood sugar damages the eyes, heart, kidneys, blood vessels, and nerves. If
your child's blood sugar continues to rise, his or her kidneys will increase

as urinary tract infections and skin infections, can increase your child's risk
of a high blood sugar emergency.
The best way to
prevent high blood sugar emergencies is to treat high blood sugar as soon as
your child has symptoms or when his or her blood sugar is significantly above
the target range (200 mg/dL or higher).
If your child's blood
sugar levels are above his or her target range, offer extra liquids to replace the
fluids lost through the kidneys. Water and sugar-free drinks are best. Avoid
caffeinated drinks, regular soda pop, fruit juice, and other liquids that
contain a lot of sugar.
