Hypoglycemia means low blood sugars usually below 80mg%. It becomes troublesome to the persons who experience them when it goes below 70mg% because important organs like the brain which are dependent on blood sugar for normal functioning start to fail (irritable, nervousness, lightheaded in the milder form of hypoglycemia, mental clouding, coma and death in the severest form). Hypoglycemia must therefore be avoided as far as possible as it is linked to impaired quality of life and increased patient mortality.
