In episode 4 of The Expanse, "CQB", there is a dead man that gets examined in the morgue and they discover he has several cybernetic implants in him, one being the "pancreatic pump". What would the use be of a pancreatic pump?
"Standard inner-ear mike, spinal stabilizer, pancreatic pump, run of the mill, for the sedentary."
Per the wikipedia page on artificial pancreases
The artificial pancreas is a technology in development to help people with diabetes automatically control their blood glucose level by providing the substitute endocrine functionality of a healthy pancreas.
There are several important exocrine (digestive) and endocrine (hormonal) functions of the pancreas, but it is the lack of insulin production which is the motivation to develop a substitute. While the current state of insulin replacement therapy is appreciated for its life-saving capability, the task of manually managing the blood sugar level with insulin alone is arduous and inadequate.
Different approaches under consideration include:
the medical equipment approach—using an insulin pump under closed loop control using real-time data from a continuous blood glucose sensor.
The clear implication is that this individual leads a highly sedentary and presumably unhealthy lifestyle. An artificial pancreas would allow their body to remain moderately healthy and regulate diabetic control long after a real pancreas would have given up the ghost.
