What Is a Normal Fasting Blood Sugar?
Most health care professionals consider a normal fasting blood sugar level to be anywhere between 70 and 99 mg/dL. Fasting generally refers to the period of time between eating dinner at night and waking up for breakfast the next morning. Glucose levels should be lowest during this period, but should be no lower than 70mg/dL. If it has not been at least four hours since food was last consumed, levels may be slightly higher than normal. Blood sugar readings lower than normal mean that it may have been too long since food was last consumed.
