Why should high blood sugar be prevented?
Blood
sugar levels that are somewhat above a
normal or near-normal range may cause symptoms, such
as increased thirst and more frequent urination. If early high blood sugar is
not treated, it may rise to a very high level, which can be life-threatening.
Over time, high blood sugar can also increase the risk for complications, such
as problems with your nerves, eyes, or kidneys.
When your child's
blood sugar level rises above 200 mg/dL, his or her kidneys will eliminate some
of the extra sugar through the urine. Along with sugar, the kidneys release
large amounts of fluid, which causes increased urination.
If your
child's blood sugar level continues to rise and liquids that are lost aren't
replaced, your child can become dehydrated. Dehydration can lead to a high
blood sugar emergency. Both of the following high blood sugar emergencies can
become life-threatening:
- Your child is at risk for a high blood sugar
emergency called a
hyperosmolar state. A hyperosmolar state can develop
if your child's blood sugar levels are consistently very high, such as above
600 mg/dL, and he or she becomes dehydrated. It is easy to overlook early
symptoms of a hyperosmolar state.
- Your child may also develop a
condition called
diabetic ketoacidosis (DKA) from high blood sugar.
Diabetic ketoacidosis can occur if your child's blood sugar levels are
consistently high, such as above 250 mg/dL, and he or she becomes dehydrated.
In ketoacidosis, your child's body burns protein and fat for energy, causing
acids and
ketones to build up in his or her blood. These ketones
can be partially released into the urine. If ketoacidosis develops, your child
needs emergency care immediately to keep the condition from getting
worse.
Often, a high blood sugar emergency can develop because of
stress to your body, such as an infection or surgery, which increases the need
for insulin.
