Blood sugar, or glucose , is the primary source of energy for every cell in your body, fueling everything from your brain's complex functions to your muscles' movements. Maintaining a stable balance of glucose in your bloodstream is crucial for optimal health. While much attention is given to high blood sugar (hyperglycemia), dangerously low blood sugar, known as hypoglycemia , can be equally, if not more, life-threatening.
