Also known as hyperglycemia, high blood sugar levels commonly occur among those with diabetes. Essentially, high blood sugar means that your body isn’t producing enough insulin or your body is unable to absorb insulin properly [1]. Food choices, illness or taking an insufficient dose of glucose-lowering medication are all common contributing factors to high blood sugar levels.
