Patients with diabetes mellitus are prone to injury, are prone to relapse, and also many other risks that may be faced by people with diabetes mellitus. As long as people with diabetes mellitus are at home, they cannot be directly supervised by nurses, unlike when they are in the hospital. So it needs to be conveyed to patients and their families how to modify the environment to maintain blood sugar stability and keep diabetes mellitus patients from developing diabetes wounds.
