Pumps deliver insulin much more precisely than anyone can with a syringe or pen injector. Pumps typically can be programmed to deliver insulin in 0.1 unit increments. Such precision is not possible with today's commercially available insulin syringes or pens. Pump users almost always report better control than they were able to achieve using even multiple daily injections. A recent study demonstrated that insulin pumps are better than multiple daily injections for adolescents.
Many people feel that pumps are better for everyone who uses insulin.
You eat when you want, when you want, since you are no longer eating to cover long-acting insulin injected hours earlier. Pump users are generally the most dedicated in the management of their diabetes. They are highly motivated, and want the utmost control over their blood sugars. They are adults and college students, teens and children who have good parental support. They all test their blood sugars frequently, often six or eight times a day.
