How would you explain the role negative and positive feedback paid in maintaining homeostasis to a newly diagnosed diabetic patient

Homeostasis is the tendency to resist change in order to maintain a stable, relatively constant internal environment.

Homeostasis typically involves negative feedback loops that counteract changes of various properties from their target values, known as set points.

In contrast to negative feedback loops, positive feedback loops amplify their initiating stimuli, in other words, they move the system away from its starting state.
