Insulin pump users have lower glycosylated hemoglobin levels than injection patients and, more importantly, they have smaller, near-normal blood sugar fluctuations. This means better health as well as the possibility of avoiding and diabetic complications and prolonging life. Also patients experience very few hypoglycemia. Insulin pumps use short-acting insulin, which has a fast onset of action. Patients can freely choose when to eat, exercise and sleep, and even if they work shifts or even travel across time zones, their blood sugar is easier to control and they live more freely. Insulin pumps can input 0.1 unit (some can even be accurate to 0.05 units), and it is impossible for current insulin syringes and insulin pens to achieve such accuracy. Children and wasted adults with diabetes are sensitive to small doses of insulin, and treatment with an insulin pump is the best option for them. The insulin pump can be used at any time and any place, just turn sideways, press a few buttons, and insulin is automatically fed into the body, which is simple and undignified, making the patient forget the hassle and pain of injections at all times.
