normal glucose levels for adults
Blood sugar level (or blood sugar concentration) is the amount of glucose (a source of energy) present in your blood at any given time. A normal blood glucose level for a healthy person is somewhere between 72 mg/dL (3.8 to 4 mmol/L) and 108 mg/dL (5.8 to 6 mmol/L).It, of course, depends on every individual alone.ote: mg/dL and mmol/L are units of measure. mg/dL is mostly used in USA whereas mmol/L is mostly used in EU and other parts of the world.
