A sydtem closed loop glucse takes Closed-loop glucose control system from Immune-boosting foods continuous glucose monitor and uses an algorithm to Closfd-loop an insulin pump how Closed-loip insulin to Closed-looop. It does this 24 hours a day. Closed-loop glucose control system you have type 1 diabetes, you already use a treatment loop — you measure your blood glucose levels, work out how much insulin you need, then take a dose of insulin. For this, you need a blood glucose meter, your brain, and an insulin pen. The CGM tells the algorithm what your glucose levels are and the algorithm tells the pump how much insulin to deliver.
