A human body consumes energy to perform different daily tasks. The source of
this energy is the food that is consumed. An organ called the pancreas, in a human body,
lying near the stomach, produces a hormone called insulin, which helps glucose to reach
all the cells of a human body. Diabetes is a metabolic disease, in which either the body
fails to make sufficient insulin or cannot utilize the insulin the way it should, which in
return causes sugar to build up in the body. Diabetes, if not controlled, causes
complications and effects heart, nerves, eyes, feet and kidneys [1].
