What do you suggest if my six year old has been having blood glucose readings from 150 to 233 is this normal?

What do you suggest if my six year old has been having blood glucose readings from 150 to 233 is this normal?

Absolutely not: The first thing that needs to be done is accurate measurement of his blood glucose levels, HgbA1C, blood ketones and several other labs.

No symptoms: Unfortunately, the complications of diabetes are insidious. Most don't know they have complications until the doctor starts looking or when things are very far along. Good blood sugar control and mgmnt of other co-occurring illness like high bp, dyslipidemia, obesity, and maybe sleep apnea will help also. Your meter can be checked thru your doctor's office. Meds may need to be adjusted, too. ...Read more
