Insulin is a hormone made in the pancreas, a gland found behind the stomach. In the stomach, food which is eaten is changed into glucose and goes into the blood stream to be used by the body to produce energy. Glucose is our main source of energy.

In a normal person, insulin helps the blood glucose to enter the body cells and be turned into energy.

Normal Person
Diabetes Person

In a diabetic (person who has diabetes) the pancreas does not produce enough insulin or the insulin that is produced fails to act normally ie it is inffective.

As a result, glucose cannot enter the body cells. Instead it collects in the blood giving rise to a high blood glucose level and then spills over into the urine.

Without insulin or ineffective insulin, the body's cells become starved of glucose, despite the high level of glucose in the blood, and thus the body lacks energy.


There are 2 main types:

Type 1   Insulin Dependent Diabetes
  • Usually develops in children and young adults
  • Due to insufficient insulin
  • Can only be controlled by insulin injections as well as proper diet and exercise
  • Usually strong family history

Type 2   Non-Insulin Dependent Diabetes
  • Commonly occurs in adults (40 years and over) and overweight individuals
  • Due to insufficient or ineffective insulin
  • Can often be controlled with just proper diet and exercise or a combination of diet, medication and exercise
  • Usually strong family history
