Type I and type 2 diabetes are two conditions that affect the body's amount of glucose and insulin. Typically, insulin helps glucose (blood sugar) enter cells after we consume food. Glucose provides the body with energy, but diabetes occurs when insufficient insulin is produced, causing blood sugar to float around the bloodstream. Over time, high blood glucose levels can cause health problems and lead to diabetes. Once you are diagnosed, you may need insulin therapy to keep your blood sugar levels steady and prevent complications like diabetic retinopathy and limb amputation.
