Blood Sugar Charts: Target Levels

A blood glucose or blood sugar chart classifies the ideal blood sugar levels throughout the day, including before and after meals. Blood sugar charts help those with diabetes to self-monitor sugar levels and accordingly calculate their blood sugar test results.

Monitoring blood sugar levels is undoubtedly a crucial part of managing diabetes.

Most of the blood sugar charts show recommended levels as a range, thus allowing for differences among individual people.

The following blood sugar charts have been taken as a reference from The American Diabetes Association (ADA), Joslin Diabetes Center (JDC), and American Association of Clinical Endocrinologists (AACE).

People with high as well as low blood sugar should be worried.

Fasting blood sugar level

Risk level and suggested action

50 mg/dL or lessDangerously low, Undoubtedly need medical attention.
70 – 90 mg/dLPossibly too low, basically an indication to increase sugar consumption, if experiencing symptoms of low blood sugar. Also better to consult a doctor.
90-120 mg/dLNormal range, generally no need to worry.
120-160 mg/dLMedium, This basically suggest that it is better to see a doctor.
160 – 240 mg/dLSignificantly too high. Steps to lower blood sugar levels are certainly needed.
240-300 mg/dLUnquestionably Too high, a sign of out of control diabetes, Obviously a visit to the doctor should be on priority list.
300 mg/dL or aboveIndeed very very high. Without a doubt, seek immediate medical attention.

Diabetes is becoming common amongst children and especially among young adults. As a parent, you need to know the normal as well as acceptable range of blood sugar levels in children.

There is always a way to control and reduce blood sugar levels as long as the levels have not reached the critical stages.
