Does using the insulin pump improve your blood sugar levels?

How's the use of the insulin pump if you were to use the insulin pump? Has that been shown to improve your blood sugar levels? So the use of insulin pump has been shown in various trials in America under FDA and within UK to lead to decreased amount of hypoglycemia and also improvement in the HbA1c. The biggest amount of the HbA1c's have been shown in research studies have been observed in patients who are on insulin pump and this is directed by the insulin pump's ability to integrate the information that is coming through the sensors and at the same time being able to vary your insulin on a more circadian rhythm fashion instead of being being able to give you a flat rate of insulin. Thank you.
