In people without diabetes, the beta cells make and release some insulin all of the time. This is a “basal” level of insulin that helps the body to function. When a person eats and their blood glucose level rises, the body releases an extra burst or ‘bolus” of insulin to help bring the blood glucose back into the target range. The insulin taken to manage diabetes is designed to work the way the body works as closely as possible. http://www.idf.org/worlddiabetesday/toolkit/pwd/insulin http://www.idf.org/worlddiabetesday/toolkit/pwd/insulin
