Diabetes is a chronic illness that affects how your body breaks down the glucose (sugar) in your blood from the food that you eat. Glucose is a key source of energy for your cells, and its level in the blood need to be balanced and at or near your goal. When you have diabetes, your body has trouble balancing glucose levels in your blood leading to high blood sugar (hyperglycemia) or low blood sugar (hypoglycemia). There are two main types of diabetes, Type 1 Diabetes (T1D) when you make little or no insulin and Type 2 Diabetes (T2D) when you don’t make enough insulin and the insulin that you make does not work well.
