Diabetes mellitus is a chronic condition that arises when the pancreas fails to produce enough insulin or when the body cannot use the insulin produced effectively (Alva, 2000). There are currently an estimated 143 million people with diabetes worldwide and this figure is estimated to rise to 300 million by 2025 (Alva, 2000 https://www.projectandmaterials.com/).

More than 90% of all people with diabetes have type 2 diabetes mellitus (www.ext.colastate
