Age. Very young children are at the greatest risk for very low blood sugar, because they are often not able to communicate symptoms.
Tight blood sugar control. Although keeping your child's blood sugar levels tightly within a target range is important, this puts him or her at risk for frequent low blood sugar levels.
Persistent high blood sugar levels. Children who have persistent high blood sugar, indicated by higher hemoglobin A1c test results, are at greater risk for diabetic ketoacidosis than children who have lower levels.
Puberty. Growth spurts and changing hormone levels that occur during puberty make it difficult to keep a child's blood sugar level within a target range.
