Diabetes mellitus (diabetes) is a metabolic disorder
A person does not respond properly to insulin (insulin resistance)
Means that individuals cannot easily regulate their blood glucose levels
Decreased blood glucose levels, known as hypoglycaemia, causes symptoms related to lack of energy due to decreased glucose availability to cells
As the brain requires a constant supply of energy, generally in the form of glucose, an extended lack of supply can result in unconsciousness and even death
Elevated blood glucose levels, known as hyperglycemia, can cause a range of symptoms
Both type 1 and type 2 diabetes can result in elevated blood glucose levels
