The regulation of blood glucose level is not that easy. Even though you take care of it, there are always some unpredictable variations just by eating a simple sweet. Moreover, it is much harder for young people, I mean those who are 8, 10 or 13 years old, and for those who already have another handicap. And as said before, if glycemia is not well regulated, it leads to big complications, illness and death. That is why doctors and researchers developed a method based on an Insulin pump. They are an answer to these kinds of problems. This involves an external pump, working with a battery, and delivering rapid insulin continually, under the skin with the help of a catheter. It injects insulin automatically without any variations, permitting diabetics to live a bit more "normally", avoiding hyperglycemia or hypoglycemia. The pump is checked every day, and you can inject more insulin, if you want to eat more, by pressing a button.
However, this therapy is not allowed for everybody. There are specific requirements :
. patients who have difficulties to keep the objectives of good glycemia: too much hypo or hyperglycemia (generally young people or those who already have a handicap)
. patients who want to increase their traitement to have a better control
. people who need smoothness for their meal, and who have problems with the mix of different types of insulin (slow and rapid)
. very active people
. pregnancy
. and other people with medical prescriptions
