Insulin is incredibly expensive and is manufactured by some of the companies making these devices. I wonder how much less insulin people use with these devices?
There is no overlap between companies that manufacture insulin and companies that manufacture diabetes-related devices. (Not for any fundamental reason, it just happened to work out that way.)
Also, the amount of insulin used is not significantly different with a closed-loop system vs. not. Although closed-loop systems do increase the benefit of faster-acting insulin relative to slower insulin, and the fastest-acting insulins are more expensive (especially inside the US).
