the answer is c, non-infectious. diabetes is a disorder of the digestive system. insulin supplied by the pancreas, is what helps the body digest glucose and starches. type 1= young, child or pre adolescent = insulin/ type 2 = oral meds, diet to control. in my experience as a nurse with type 1, type 2 starts with the oral meds. later in life, type 2's get insulin injections because of age, health state.
