Blood sugar, also known as glucose, is the main type of sugar found in your blood. It comes from the food you eat, especially carbohydrates like bread, rice, and fruits. Your body uses blood sugar as a primary source of energy, which is essential for all its functions. Maintaining the right level of blood sugar is crucial for your overall health. When you eat, your pancreas releases a hormone called insulin to help move glucose from your blood into your cells. If blood sugar levels are too high or too low, it can lead to health issues like diabetes or hypoglycemia. Regular monitoring and a balanced diet can help keep blood sugar levels stable.
