Some people with diabetes use a computerized pump -- called an insulin pump -- that gives insulin on a set basis. You and your doctor program the pump to deliver a certain amount of insulin throughout the day (the basal dose). Plus, you program the pump to deliver a certain amount of insulin based on your blood sugar level before you eat (bolus dose).
Knowing your blood-sugar levels and acting accordingly are among the most important ways to treat T1D. Monitoring lets a person know when insulin may be needed to correct high blood sugar or when carbohydrates may be needed to correct low blood sugar. Monitoring blood sugar can be done using traditional blood-sugar meters or continuous glucose monitors (CGMs).
Diabetes is an illness related to elevated blood sugar levels. When you stop releasing and responding to normal amounts of insulin after eating foods with carbohydrates, sugar and fats, you have diabetes. Insulin, a hormone that’s broken down and transported to cells to be used as energy, is released by the pancreas to help with the storage of sugar and fats. But people with diabetes don’t respond to insulin properly, which causes high blood sugar levels and diabetes symptoms.
Normally, blood glucose levels are tightly controlled by insulin, a hormone produced by the pancreas. Insulin lowers the blood glucose level. When the blood glucose elevates (for example, after eating food), insulin is released from the pancreas. This release of insulin promotes the uptake of glucose into body cells. In patients with diabetes, the absence of insufficient production of or lack of response to insulin causes hyperglycemia. Diabetes is a chronic medical condition, meaning that although it can be controlled, it lasts a lifetime.
