Insulin ensures that the excess glucose is absorbed out of the blood, taken
up by the cells and converted to energy. This normalises the blood glucose
levels again.


In a diabetic, the secretion and/or functioning of insulin is ineffective or
totally dysfunctional.
- Excess glucose continues to build up in the bloodstream and the
blood glucose level stays high.


In diabetics, hyperglycaemia can be caused by:
- eating foods high in sugar
- not taking insulin injections or other medication, or incorrect use
of medication
- too little exercise & sustained stress
