A normal blood sugar level ranges approximately 60 to 120 mg/dL, states "Pharmacotherapy: A Pathophysiologic Approach." Low blood sugar, termed hypoglycemia, is a measurement of less than 60 mg/dL, which is a sugar level that is not adequate to fuel your body. You may experience hypoglycemia as a condition by itself or as a complication of another disease or disorder. Typically, if you are diabetic you may experience hypoglycemia if you have taken too much medication, missed a meal or eaten less than usual. If you develop any signs and symptoms of low blood sugar, you should inform your physician.
