Question 1

Do I need to fast for an HbA1c test?

Accepted Answer

No. HbA1c reflects the past two to three months, so a recent meal does not change it. Fasting glucose does need at least eight hours without food or drinks other than water.

Question 2

Can prediabetes be reversed?

Accepted Answer

Often, yes. Losing a modest amount of weight if you carry extra, being active most days and eating fewer refined carbohydrates bring blood sugar back into the normal range for many people. Rechecking at least once a year shows whether it is working.

Question 3

How often should blood sugar be checked?

Accepted Answer

Many guidelines suggest screening adults from age 35, or earlier with risk factors such as excess weight, a family history of diabetes or diabetes in a past pregnancy, and repeating every three years if results are normal. People living with diabetes usually have HbA1c checked every three to six months.

Question 4

What is a normal fasting blood sugar?

Accepted Answer

A fasting glucose below 100 mg/dL (5.6 mmol/L) is usually normal. Levels below 70 mg/dL (3.9 mmol/L) are low and, with symptoms such as shakiness, sweating or confusion, need prompt attention.
