About Blood Sugar Level Ranges

Blood sugar refers to the amount of glucose in a person's blood. Blood sugar levels, which are measured in milligrams of glucose per deciliter of blood (mg/dl), should fall within a certain range. Levels that are too high or too low can result in a number of dangerous medical conditions.

  1. Identification

    • Normal fasting blood sugar levels should fall between 70 and 99 mg/dl in adults who are not diabetic. Levels ranging between 100 and 125 mg/dl on a Fasting Plasma Glucose Test (FPG) indicate pre-diabetes; measurements of 126mg/dl or above indicate diabetes.

    Significance

    • A person is hyperglycemic when he has blood sugar levels that are high, or elevated. Hypoglycemia occurs when blood sugar levels are too low, normally below 70 mg/dl.

    Considerations

    • According to Islets of Hope, a resource for individuals with diabetes, fasting blood sugar levels for diabetic adults typically range between 90 and 130 mg/dl, although a physician may provide individuals with ranges specific to them.

    Prevention/Solution

    • People with diabetes should check their blood sugar often. Insulin may be prescribed to help regulate blood sugar levels, and changes in diet can also be beneficial.

    Notable Fact

    • When a person is stressed mentally or physically, it can cause blood sugar levels to rise.
