A person with type 1 diabetes should balance insulin delivery to manage their blood glucose level.

In some cases, the insulin pumper may want to wear the pump during sports to be able to increase and decrease insulin delivery as needed.

But for young children, parents must assume the responsibility for properly programming the machine's insulin delivery.

"The worst part of being a diabetic is not insulin delivery, it's the finger tests," he said.

A pump has an alarm system to tell you when something is wrong with insulin delivery or if the pump's battery is getting low.

Therefore pump users typically monitor their blood sugars more frequently to evaluate the effectiveness of insulin delivery.

In some extreme cases the insulin delivery will appear to have no/little effect on lowering blood glucose levels and the site must be changed.

Currently there are no mature algorithms to automatically control the insulin delivery based on feedback of the blood glucose level.

NN1952 has been designed to address some of the key challenges relating to oral insulin delivery.

Several other non-transplant methods of automatic insulin delivery are being developed in research labs, but none is close to clinical approval.
