How do insulin pumps help prevent future complications?

Control: If used correctly, an Insulin pump can help you achieve better blood sugar level which will prevent future complications. The goal is to keep A1c < 6.5 or 7%. Your risk of complications is lower with these A1c level.

Tight Glycemic: control helps prevent diabetic complications like kidney disease, heart disease, peripheral vascular disease, retinal disease, and infections by preventing spikes in blood sugar which cause damage to blood vessels which degrade multiple organ systems. This helps meaningfully extend both the quality and duration of life for diabetics. Hope this helps!
