Insulin aspart is a form of insulin, which is a hormone that is naturally produced by the pancreas. This hormone is important for several functions, such as controlling blood sugar. Insulin helps the cells of your body remove glucose ("sugar") from your bloodstream. This sugar fuels your body's cells, giving them the energy they need to work properly. You may need to take insulin if your pancreas has trouble making enough insulin, which is the case in people with type 1 diabetes and in some people who have type 2 diabetes.
Normally, your body is able to maintain proper levels of sugar in your blood and inside your cells. However, in people with type 1 diabetes (and sometimes type 2 diabetes), the pancreas has trouble making insulin. This causes too much sugar to accumulate in the blood. Too much sugar can also accumulate in the blood if your body has trouble responding to normal levels of insulin, as is common in type 2 diabetes. Over time, high levels of sugar in the blood can lead to serious health problems in the eyes, feet, hands, kidneys, and heart.
Insulin aspart is a rapid-acting insulin medication. It starts working quickly, produces a sharp peak in insulin levels, and drops off quickly. It is designed to help control the blood sugar spike that occurs after meals. Most people who take insulin aspart will also need a long-acting insulin in addition to insulin aspart to provide a steady background level of insulin to help control blood sugar throughout the day.
