A diabetic can maintain normal blood sugar levels by having his blood glucose level tested regularly, maintaining a healthy diet and taking all necessary medication, the American Diabetes Association explains. These measures help prevent both hyperglycemia and hypoglycemia.
A diabetic can ensure his blood sugar level stays within the normal range by undergoing periodic testing. There are home testing solutions available, explains WebMD. The test involves pricking the skin and placing the blood onto the test strip. A blood glucose meter provides a reading of the sugar levels. A diabetic can determine if he is suffering from hypoglycemia or hyperglycemia. With hypoglycemia, he should consume high-sugar foods or take his prescribed medication. With hyperglycemia, the diabetic should immediately take glucose-lowering medication, advises Mayo Clinic. A balanced diet and regular exercise help a person to manage his blood sugar levels.
Blood sugar testing should be performed during various times of the day to check for abnormalities, notes WebMD. The specific tests are known as the oral glucose tolerance test, the random blood sugar test and the fasting plasma glucose test. A blood sugar reading of 140 milligrams per deciliter two hours after eating is considered normal. If the person is fasting, readings of less than 100 milligrams per deciliter are considered normal. If below or above these levels, an underlying serious condition could be present, Mayo Clinic advises.
