what are blood sugar levels

Blood sugar levels, also known as blood glucose levels, refer to the amount of glucose present in your bloodstream. Glucose is a type of sugar that comes from the food you eat and is your body's primary source of energy. Maintaining healthy blood sugar levels is crucial for overall health, especially for individuals with diabetes or prediabetes.
